The panel's verdict
doo is event-registration and ticketing SaaS from Munich-based doo GmbH, and its highest scores are shop and registration (6 to 7) and invoicing and tax (6 to 7): ticket categories, conditional questions, promotion codes and widget or iFrame embedding on any number of websites, a seating tool for events up to roughly 2,250 attendees, and per-category VAT with mixed 0%, 7% and 19% rates printed on invoices doo creates for the organiser. Payments and fees and check-in and on-site score 5 to 6: the on-site module is in beta, recommended for up to 500 attendees and requiring a stable internet connection, and the captured pages give different accounts of refunds — a features page describes automatic repayment while the terms state doo does not process refunds unless expressly agreed. Sovereignty sits at 6 across the bench — EU data centres with EU-only servers on request, ISO/IEC 27001 stated — though data centres are unnamed and no subprocessor list is published. Scores sat close; the widest spread is attendee data ownership, 5 to 7. Pricing transparency trails at 4 to 5.
Speaks for it
- Registration is configurable with ticket categories, conditional tickets tied to questions, promotion codes, add-on products and widget or iFrame embedding on any number of websites
- VAT is set per ticket category, with mixed 0%, 7% and 19% rates possible in one event and the exemption reason printed on bookers' invoices
- doo is the processor under a downloadable Article 28 GDPR agreement, with attendee and booking data exportable as Excel or CSV at any time
- The exit path is unusually explicit: up to 30 days of transition support, at least 30 days to retrieve data after termination, and early-termination compensation capped at the remaining fees
- On-site check-in validates add-on products such as workshops and catering and shows check-in numbers in real time
Held against it
- The captured pages give different accounts of refunds — a features page describes automatic repayment while the terms state doo does not process refunds of ticket prices unless expressly agreed
- The on-site module is in beta, recommended for events up to 500 attendees, and its documented setup requires a stable internet connection
- We found no public information naming the data centres, the subprocessors with their locations, or the company's ownership
- We found no public information on payout timing, chargeback handling or passing service fees on to buyers
- The documented accounting export is Excel or CSV, with no public information on a DATEV export or e-invoice formats such as XRechnung or ZUGFeRD
Best for
- You organise German events that mix VAT rates in one event — 0%, 7% and 19% — and want invoices created on your behalf with your VAT ID on them
- You need a configurable registration flow with ticket categories, conditional questions and promotion codes, embedded by widget or iFrame on any number of your own websites
- You run seated events of up to about 2,250 attendees and want the seating plan to feed badges, check-in and table plans
- You face a data-protection review and need an Article 28 processor agreement, exports at any time, and a stated retrieval window of at least 30 days after termination
Avoid if
- You need on-site check-in for events well beyond 500 attendees — the module is documented for small to medium events with a maximum of 500
- Your check-in stations cannot rely on a stable internet connection — the documented hardware requirements state one is required per station
- Your refund process depends on automatic repayment of ticket prices — the terms state doo does not process refunds of ticket prices unless expressly agreed
- Your accounting hand-off needs more than the documented Excel and CSV exports

Ticket shop, checkout & registration
Show reasoningHide reasoning
How this is scored
How a ticket or a registration is sold: ticket types and categories, member and early-bird prices, discount codes, bundles and add-ons, a shop embeddable on the organiser's own website or under its own domain, custom questions per ticket and per attendee, group and company bookings, capacity limits and waiting lists, reserved seating with a seating plan, recurring dates and course series, several languages, and an accessible mobile checkout.
0 — Not a ticketing or registration tool; tickets cannot be sold and registrations cannot be taken in the product.
3 — An event page on the platform with a few ticket types and a fixed sign-up form; embedding, custom questions, capacity rules or seating are basic or not described.
5 — Several ticket types with prices, quotas and sale periods, discount codes, custom questions per attendee, a shop embeddable on the organiser's website as a widget or link, capacity limits with a waiting list, and a checkout that works on a phone.
8 — A white-label shop under the organiser's own domain and design, reserved seating with a seating-plan editor, add-ons and bundles, group and company bookings with several attendees per order, conditional questions, member prices by code or login, recurring dates and course series, several languages, and the checkout's accessibility stated.
10 — A shop that fits any event: multi-event and season tickets, timed entry and seat holds, a checkout that the organiser can extend (API, custom fields synced to a CRM), an accessibility conformance statement (WCAG level named), and the conversion and drop-off of the checkout reported to the organiser.
The Conference Organiser
Multiple ticket categories with individual prices, promotion codes, conditional tickets combined with questions, add-on products that explicitly include workshops with minimum and maximum quantities, and quotas plus purchase periods are all documented, and the registration embeds as a widget or iframe into any number of our own websites; the seating tool adds an interactive plan with automated placement and down-stream reuse for badges. We found no public information on waiting lists, a shop under our own domain and design, member prices by code or login, recurring course series, or checkout languages and checkout accessibility, which keeps it below the top band. 1 2 8 10 18
The Venue Promoter
The ticket setup fits my nights: free and paid events with several ticket categories and prices, minimum and maximum quantities per total and per booking, purchase periods, promotion codes, add-on products like VIP packages, conditional tickets combined with questions, a checkout in responsive design, and registration embedded as a widget or iFrame on as many of my sites as I like. The seating tool is a full plan editor with interactive seat and table assignment, reusable layouts and roughly 2,250 attendees, though for a standing club a waiting list, member prices, shop languages beyond the German and English documentation, and an accessibility statement for the checkout are things we found no public information on. 1 2 10
The Course Provider
Configurable registration forms with several ticket categories, conditional tickets tied to questions, add-on products such as workshops, quota and sale-period rules, promotion codes and one-click prefilled registration are all documented, as is embedding by widget or iFrame on as many websites as I like, plus a deep reserved-seating tool. For my eight-week evening courses, though, we found no public information on a waiting list that refills a cancelled seat, on recurring dates or course series, member prices, or an accessibility statement for the checkout. 2 8 10 1
The Revenue Accountant
Registrations are built step by step with configurable forms, ticket categories, conditional tickets linked to questions, minimum and maximum quantities with purchase periods, promotion codes and add-on products, embedded by widget or iFrame in unlimited websites, with a responsive checkout. A seating tool adds interactive seat and zone placement, automated placement rules and multi-event plans that can be embedded on my own website. We found no public information on a shop under my own domain, waiting lists, member prices, recurring course series, checkout languages or an accessibility statement for the checkout. 1 2 8 10
The Data Protection Officer
Configurable registration forms with per-category and conditional questions, quota, quantity and sale-period rules, widget or iframe embedding on any number of club websites, paid add-on products, promotion codes, and a genuinely deep seating tool with automated placement and catering preferences taken into account. What keeps me below the top anchors: we found no public information on a shop under the organiser's own domain, member pricing, recurring course series, or an accessibility statement for the checkout. 1 2 10
The Skeptic
Registration is configurable with several ticket categories, conditional tickets combined with questions, add-on products with minimum and maximum quantities, promotion codes, and widget or iFrame embedding on any number of websites, alongside a seating tool with interactive zone and seat placement for events up to about 2,250 attendees. I found no public information on a shop under the organiser's own domain, member pricing by login, recurring course series, several shop languages, or an accessibility statement for the checkout. 1 2 10 18
Payments, payouts, fees & refunds
Show reasoningHide reasoning
How this is scored
How the money moves: payment methods offered to buyers (cards, PayPal, SEPA direct debit, invoice, local methods), whether the organiser connects its own payment account or the platform collects as merchant of record, when the revenue is paid out (continuously, before the event, or after it), the per-ticket and payment fees and whether they can be passed on to the buyer, refunds of single tickets and of a cancelled event, ticket transfer and resale, and chargebacks.
0 — No payment of any kind; the product only collects free registrations.
3 — Online card payment through the platform; payout timing, fee model, refunds or buyer-paid fees are basic or not described.
5 — Several payment methods including cards and PayPal or SEPA, the fee per ticket stated with the option to pass it to the buyer, the payout schedule stated, and refunds of single orders and of a cancelled event issued from the product.
8 — A choice between the organiser's own payment account (Stripe, PayPal, Mollie or similar) and platform collection, payouts before the event stated with their conditions, invoice and bank transfer for business buyers, partial refunds and refund policies set per event, ticket transfer or resale by buyers, and chargeback handling explained.
10 — Full control of the money: the merchant of record named for each set-up, payout timing and any reserve held published, every fee itemised per order, refunds, transfers and resale with the organiser's rules enforced, and the cancellation process for an event documented end to end.
The Conference Organiser
Purchase on account, PayPal, credit card and direct debit are documented with the organiser choosing methods and periods, and we can either connect our own payment provider or have participant payments run through an escrow account in doo's name; the fee charged to us is published in the terms as 0,99 EUR per ticket plus, for paid events, 0,49 EUR + 5,9% of the ticket price excluding VAT. Payout timing, chargeback handling, buyer-paid fee options and ticket transfer are not described, and the captured pages give different pictures of refunds: the registration features describe cancellation management with automatic repayment, while the terms state doo does not process repayments of ticket prices unless expressly agreed. 2 8 11
The Venue Promoter
The money routes are real — my own payment provider, doo's default provider, or payments through an escrow account in doo's name — with purchase on account, PayPal, credit card and direct debit offered, and the fee is published: 0,99 EUR je Ticket plus 0,49 EUR + 5,9% des Ticketpreises at paid events, excluding VAT, billed to me monthly in arrears. But no page states when the ticket money lands in my account before the show, nothing says I can push the fee onto the twelve-euro ticket price, and the captured pages give different statements on refunds — the terms state doo does not process refunds of ticket prices unless expressly agreed otherwise, while the feature page describes automatic repayment with invoice adjustment and a cancellation invoice. 2 8 11
The Course Provider
Purchase on account, PayPal, MasterCard/Visa, direct debit and Amex/Discover are the documented methods, and I can integrate my own payment provider, use the doo standard provider or handle payment myself, with collection either through the organiser's provider or an escrow account in doo's name under power of attorney. The service fee to me as organiser is stated as "0,99 EUR je Ticket sowie bei kostenpflichtigen Veranstaltungen 0,49 EUR + 5,9% des Ticketpreises (zzgl. USt.)" with acquirer surcharges passed through, but we found no public information on payout timing, passing fees to buyers, ticket transfer or chargeback handling; the captured pages also describe refund handling differently — a feature page promises automatic repayment on cancellation while the terms state doo does not process refunds of ticket prices unless expressly agreed. 11 2 8
The Revenue Accountant
The money can flow either through my own payment provider, doo's standard provider, or an escrow account in doo's name under a separate power of attorney, with purchase on account, PayPal, credit card and direct debit offered and the organiser choosing methods and periods. The service fee is published as 0,99 EUR per ticket plus, for paid events, 0,49 EUR + 5,9% of the ticket price (plus VAT), billed to me monthly in arrears, with payment-provider surcharges passed through. The captured pages give different accounts of refunds — the features page describes cancellation management with automatic repayment while the terms state doo does not handle refunding of ticket prices unless expressly agreed — and we found no public information on payout timing, passing fees to buyers, partial refunds, ticket transfer or chargebacks. 2 8 11
The Data Protection Officer
The terms offer a real choice between the club's own payment provider and collection through an escrow account in doo's name, with purchase on account, PayPal, card and direct debit among the methods, and a published service fee of 0,99 EUR je Ticket plus 0,49 EUR + 5,9% des Ticketpreises for paid events. Payout timing, chargeback handling and passing fees to the buyer are undocumented, and the captured pages give different pictures of refunds: the terms state doo assumes no unwinding of paid ticket prices unless expressly agreed, while the feature page describes automatic repayment with cancellation invoices. 2 8 11
The Skeptic
Buyers can pay by purchase on account, PayPal, MasterCard/Visa credit card, direct debit and, via PayPal, American Express and Discover; the organiser can connect its own payment provider, use doo's default, or self-manage, with platform collection running through an escrow account in doo's name. The captured pages give different accounts of refunds — the features page promises automatic repayment with cancellation invoice, while the terms state doo does not process refunds of ticket prices unless expressly agreed — and I found no public information on payout timing, chargebacks, or buyer-side transfer and resale. 2 8 11
VAT, invoices & accounting handoff
Show reasoningHide reasoning
How this is scored
How ticket revenue reaches the books correctly: the VAT rate set per ticket or product (reduced rates for concerts and culture, exemptions for education and seminars), gross and net prices shown, invoices to buyers in the organiser's name with consecutive numbers, business buyers with company name and VAT ID, reverse charge for cross-border events, cancellation invoices and credit notes, the platform's own fee invoice, e-invoicing, and exports to DATEV or named accounting systems.
0 — No receipts or invoices; the organiser has to produce every invoice outside the product.
3 — An order confirmation or simple receipt per booking; VAT rates, invoices in the organiser's name, business buyers or accounting exports are basic or not described.
5 — VAT rate configurable per ticket, invoices generated in the organiser's name with its tax details and consecutive numbers, company name and address captured for business buyers, cancellation invoices on refund, and a sales export as CSV or to at least one named accounting system.
8 — Several VAT rates in one order, net prices for business buyers, VAT IDs validated and reverse charge applied, e-invoices (XRechnung or ZUGFeRD) for public and business buyers, a DATEV export with booking data, the platform's fee invoice separated from ticket revenue, and whether the platform sells as agent or in its own name stated.
10 — Tax handled per country: VAT rules for events in several EU countries documented with the place of supply, invoices and credit notes stated as compliant with national invoice law, a reconciliation of payouts, fees and ticket revenue per event, and a GoBD-compliant archive or audit export.
The Conference Organiser
doo creates the booker invoices on the organiser's behalf, in German or English, customisable per event with our logo, with a separate VAT rate per ticket category including mixed 0%, 7% and 19% rates and a printed exemption reason, and our VAT ID must be stored before the event can go live; cancellation invoices and a booking overview with net and VAT totals, invoice numbers and cancellation invoice numbers round this out. We found no public information on e-invoicing formats such as XRechnung or ZUGFeRD, a DATEV export, net prices for business buyers with validated VAT IDs and reverse charge, or an accounting hand-off beyond Excel and CSV. 2 8 13 14 18
The Venue Promoter
doo writes the invoices to my buyers on my behalf with my VAT ID on them, lets me set the rate per ticket category — 7% for the concerts, 19% elsewhere, mixed rates in one event — prints the exemption reason at 0%, produces cancellation invoices, and offers German or English invoice templates with my logo; a VAT ID or tax number must be stored before an event can go live. We found no public information on net prices for business buyers, reverse charge, XRechnung or a DATEV export; the export to my books is Excel or CSV. 2 8 13 14 18
The Course Provider
This matches my mixed shop: an "Exempt from VAT" event type allows categories at 0% alongside 7% or 19% in one event, a separate VAT rate per ticket category appears on bookers' invoices with my VAT ID, and the required exemption reason is printed on invoices. doo creates the invoices to participants for the organiser, customisable with my logo in German or English, including cancellation invoices, and booking overviews with net totals, VAT totals and invoice numbers export to Excel. We found no public information on reverse charge for cross-border bookings, VAT-ID validation, e-invoices or an export to a named accounting system such as DATEV. 13 14 8 2 18
The Revenue Accountant
I can set a separate VAT rate per ticket category — 0% only for private events, 7% or 19% for taxable ones, or mixed rates on exempt events with the exemption reason printed on booker invoices — and my VAT ID or tax number must be stored before an event can go live, appearing on the invoices doo creates for me as organiser. Cancellation invoice numbers, net totals and VAT totals sit in the booking export, and doo's service fee is billed to me separately, which keeps the fee invoice apart from ticket revenue. The export reaches me only as Excel or CSV; we found no public information on a DATEV or other named accounting export, reverse charge, buyer VAT-ID validation, or e-invoice formats. 2 8 13 14 18
The Data Protection Officer
VAT is configurable per ticket category with 0, 7 and 19 percent options, an exemption reason printed on bookers' invoices, the organiser's VAT ID required before an event can go live, invoices created by doo on the organiser's behalf in German or English with template control, cancellation invoice numbers tracked, and booking exports as Excel or CSV. We found no public information on reverse charge for cross-border events, e-invoices, DATEV or another named accounting export, so the handoff to the club's accountant stays partly manual. 8 13 14 18
The Skeptic
A VAT rate is set per ticket category, event types allow 0%, 7% and 19% mixed within one event with the exemption reason printed on invoices, and doo creates the participants' invoices for the organiser showing the organiser's VAT ID, cancellation invoices included, with Excel and CSV exports of bookings and attendees. I found no public information on consecutive invoice numbering, validation of business buyers' VAT IDs or reverse charge, e-invoices such as XRechnung or ZUGFeRD, or a DATEV export. 2 8 13 14 18
Check-in, badges & on-site sales

How this is scored
What happens at the door: a check-in app that scans tickets on phones or scanners, offline scanning and several devices at once, entrances and time slots, check-in lists by name, badge printing with attendee data and QR code, box office and on-site sales with card terminals, walk-in registration, session and room check-in at conferences, attendance certificates, and live attendance figures.
0 — No check-in; tickets cannot be validated at the event.
3 — Tickets with a QR code and a guest list to tick off by hand or in a simple app; offline use, several devices, badges or on-site sales are basic or not described.
5 — A free check-in app for iOS and Android that scans tickets on several devices at once, works offline and syncs, a searchable guest list, and live check-in numbers in the dashboard.
8 — Badge printing with attendee data and QR codes, access rules per entrance, session or day, box office sales on site with a named card terminal, walk-in registration, dedicated scanner hardware supported or rented, and attendance certificates for courses.
10 — On-site operations at scale: self-service kiosks or turnstile integration, session check-in feeding continuing-education credits, cashless or on-site payments reconciled with online sales, and the hardware, offline limits and failover documented.
The Conference Organiser
QR and wallet scanning on our own or rented handheld scanners, search-and-check-in for forgotten tickets, walk-in registration on site, badge and label printing with attendee name corrections possible at the door, product-level check-in that validates workshop and add-on permissions, and real-time attendance counts are all documented. Two things hold it back for a 900-person congress: the pages themselves describe the on-site management as suited to small and medium events of up to about 500 attendees and state that a stable internet connection is required, and we found no public information on offline scanning, box-office sales with card terminals, or attendance certificates feeding continuing-education points. 15 16
The Venue Promoter
The door kit is heavier than my basement needs: QR and wallet scanning on owned or rented handheld scanners with a laptop or tablet per station, badge and label printing on a Windows machine, search-and-check-in for ticketless guests, walk-in registration, product check-in for the VIP packages, and live attendance numbers. But the documentation states a stable internet connection is required — no offline door for two volunteers without signal — the solution is in beta with a stated ceiling of about 500 attendees, activation by doo and purchased scanners come first, and we found no public information on box-office sales with a card terminal. 15 16 18
The Course Provider
QR check-in with my own or rented handheld scanners, search-and-check-in for attendees who forgot their ticket, on-site registration, badge and label printing with an HTML template, product-level check-in for workshops, and real-time attendance figures are all documented. The tool is described as in beta with important functions still missing, needs a stable internet connection per station — we found no public information on offline scanning — and is recommended for events up to 500 attendees, with card-terminal box-office sales and attendance certificates not described beyond name corrections for badges or certificates. 15 16 18
The Revenue Accountant
The on-site module scans QR codes and wallet tickets with own or rented handheld scanners across stations of laptop or tablet plus 2D scanner, checks in forgotten-ticket attendees by search, registers walk-ins, prints badges or labels from an HTML template, validates add-on products such as workshops and catering, and reports check-ins in real time. The hardware requirements state that a stable internet connection is required, the module is in beta and recommended for events up to 500 attendees. We found no public information on box-office card terminals, session or room check-in, or attendance certificates. 10 15 16 18
The Data Protection Officer
QR and digital-wallet scanning on laptop or tablet with own or rented handheld scanners, badge and label printing, walk-in registration and search for attendees without tickets, product-level check-in for workshops and catering vouchers, and real-time attendance figures.

The Skeptic
On-site management scans QR codes and wallet tickets with own or rented handheld scanners, checks in ticketless attendees via search, registers walk-ins, prints badges, validates add-on products like workshops by category, and shows check-in numbers in real time. The documented setup requires a stable internet connection with no offline mode stated, the feature is in beta and described for events up to about 500 attendees with activation by doo required, and I found no public information on box-office sales with a card terminal or session-level check-in. 15 16
Attendee data & the customer relationship
Show reasoningHide reasoning
How this is scored
Who the ticket buyer belongs to: whether the organiser is the controller of attendee data and the platform its processor, or the platform a controller in its own right; whether buyers must create an account on the platform; whether the platform markets other events to the organiser's buyers or lists the event on its own marketplace; consent for the organiser's newsletter collected in the checkout; messages to attendees; attendee data exportable at any time; and deletion and anonymisation after the event.
0 — The organiser receives no attendee data at all; the platform keeps the buyer relationship entirely.
3 — A guest list visible to the organiser; who is controller, the platform's own marketing to buyers, export or deletion are basic or not described.
5 — Attendee data exportable by the organiser at any time, the organiser named as controller with a data processing agreement offered, buyers able to book without a platform account, newsletter consent for the organiser collectable in the checkout, and messages to attendees from the product.
8 — A white-label set-up in which buyers see only the organiser, the platform stated not to market other events to the organiser's buyers (or the opt-out explained), the platform's marketplace listing optional, deletion and anonymisation of attendee data after the event configurable, and attendee data synced to a named CRM or via API and webhooks.
10 — The organiser owns the relationship and can prove it: the controller and processor roles documented for every data flow, no platform account or platform marketing by default, retention set per event and enforced, and a complete export of orders, attendees and answers that a successor tool can import.
The Conference Organiser
doo is contractually our processor with an Article 28 agreement published for download, attendee and booking data exportable as Excel or CSV at any time, messaging through contact groups and payment reminders, deletion or anonymisation once the purpose falls away, and a genuinely strong exit path with a 30-day transition, at least 30 days to retrieve data and termination capped for switching providers. We found no public information on booking without a platform account, newsletter consent collected in the checkout, retention configurable per event, or attendee data synced to a named CRM. 3 5 7 8 18

Last month's buyers are mine to mail: the attendee list and booking overview download as Excel or CSV at any time, one row per attendee, doo acts as processor under an Article 28 agreement that is part of the contract, I can filter contacts into groups and send them individual messages, data is deleted or anonymised once its purpose is served, and I get at least 30 days after termination to pull everything out. We found no public information on a white-label set-up, whether buyers need a doo account, or newsletter consent collected in the checkout; doo's own attendee terms and privacy information show to my buyers by default unless I replace them. 3 5 7 8 18

The terms name doo as processor under an Article 28 agreement that is part of the contract, and I can pull the booking overview and attendee list as Excel or CSV at any time, message contacts in filtered groups, and after termination retrieve my data for at least 30 days with transition support. The platform is restricted to my own events with third-party ticket resale prohibited, and data is deleted or anonymised once the purpose falls away, subject to legal retention duties. We found no public information on whether buyers need a platform account, white-label set-up, newsletter consent collected in the checkout, or per-event retention settings. 3 5 7 8 18
The Data Protection Officer
The terms name doo as Auftragsverarbeiter with a data processing agreement under Article 28 GDPR that is an integral part of the contract and downloadable, booking and attendee data exportable at any time as Excel or CSV, attendee messaging and contact groups from the product, no ticket resale or marketplace promotion, deletion or anonymisation once the purpose falls away subject to statutory retention, and a 30-day retrieval window with transition support on exit. We found no public information on booking without a platform account, newsletter consent collected in the checkout, or per-event retention settings, and doo's default attendee terms and privacy information are shown to participants unless the organiser replaces them. 3 5 7 8 18
The Skeptic
doo is contractually the processor with an Article 28 agreement available for download, attendee and booking data export as Excel or CSV at any time, and an unusually explicit exit — a 30-day transition phase, at least 30 days to retrieve data after termination, and switching under the EU Data Act with an early-termination charge capped at the remaining fees. The default terms and privacy information shown to participants are doo's, replaceable by the organiser, and I found no public information on whether buyers must create an account, on newsletter consent collected in the checkout, or on retention configurable per event. 5 7 8 18
European sovereignty
panel opinion
Show reasoningHide reasoning
How this is scored
Who the contracting entity and the parent company are, where attendee, order and payment data are hosted, and who the subprocessors are (hosting, payment providers, email delivery, analytics, support). Independently sourced by the sovereignty pipeline; attendee lists show who goes where and when, and a conference list holds names, employers and dietary or accessibility answers, so the whole chain counts, not only the database.
0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.
3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.
5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (payments, email, analytics, support) run through non-EU providers without a stated safeguard.
8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated.
10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, a self-hosted or on-premises option or data export and deletion documented, and certifications published with their scope rather than implied.
The Conference Organiser
The contracting entity is doo GmbH at a Munich address with a commercial register entry and a German VAT ID, the platform runs in data centres within the European Union with EU-only processing available on request, an ISO/IEC 27001 certification is stated and a data processing agreement is published. The hosting infrastructure itself is not named, we found no public information on subprocessors and their locations, and the certification documents are provided on request after review rather than published with their scope. 1 5 6 8

What I could not find published is the named hosting infrastructure, the list of subprocessors with their locations, and the ownership behind the company. 1 5 6 8

The contracting entity is doo GmbH, Hultschiner Straße 8, Munich, with a German VAT ID, the platform runs in professional data centres within the European Union with EU-only servers available on request, a data processing agreement is published for download, and ISO/IEC 27001 certification is stated. We found no public information naming the data centres or the individual subprocessors for payments, email and similar services, so parts of the chain stay unverified. 6 8 5 1
The Revenue Accountant
The contracting entity is doo GmbH of Munich, registered at Amtsgericht München under HRB 204689, the platform runs in data centres within the EU with EU-only servers on request, an Article 28 data processing agreement is published for download, and ISO/IEC 27001 certification is stated. We found no public information naming the hosting infrastructure, the subprocessors for payments, email, analytics and support with their locations, or the ownership of the company. 1 5 6 8
The Data Protection Officer
The contracting entity is doo GmbH of Munich (HRB 204689, Amtsgericht München), the platform runs in data centres within the European Union with exclusively EU servers available on request, a data processing agreement is published for download, and ISO/IEC 27001 certification is stated with certificates and penetration test reports provided on request. The data centres are not named and no subprocessor list with their countries is published, which is my sticking point: our attendee lists carry names, employers and dietary or accessibility answers, and I cannot yet assess the whole chain of hosting, payment, email and support providers. 1 5 6 8
The Skeptic
The contracting entity is doo GmbH in Munich, registered at the Amtsgericht München, the platform is stated to run in data centres within the EU with exclusively EU servers available on request, an ISO/IEC 27001 certification is stated with certificates and penetration test reports on request, and a data processing agreement is published. The data centres themselves are not named, no subprocessor list with locations is published, and I found no public information on the company's ownership — so the chain from database to email delivery to payment provider remains unproven. 1 5 6 8
Pricing transparency

Show reasoningHide reasoning
How this is scored
Whether an organiser can compute the real cost of an event from public pages alone: the fee per ticket or per registration (fixed, percentage or both), payment processing fees, whether fees are charged to the organiser or added to the buyer's price, free events, subscriptions or credit packs, payout and refund fees, add-ons (seating, white label, badges, box office), hardware rental, minimums and term, and VAT on the fees.
0 — No public prices at all; every organiser is a sales call.
3 — A starting price or "free for free events" exists, but the fee for paid tickets, payment fees or who pays them is unclear.
5 — The fee per ticket and the payment processing fees are public with the main inclusions, but at least one commonly needed piece (refund fees, white label, seating, box office, hardware) is unpriced or "on request".
8 — Every fee published with its rule (per ticket, percentage, cap), the share paid by buyer and organiser stated, add-ons and hardware priced, payout and refund fees listed, and VAT treatment of the fees stated.
10 — Complete price computability: the cost of an event derivable for a given ticket price, ticket count and payment mix, with every add-on, hardware, support and payout fee and the cancellation and data-return terms published.
The Conference Organiser
The terms publish the fee rule clearly: 0,99 EUR per ticket plus, for paid events, 0,49 EUR + 5,9% of the ticket price, excluding VAT, invoiced to the organiser monthly in arrears, with payment-provider surcharges passed through, fourteen-day payment terms and a six-week notice plus termination right on increases above 5 percent. What we cannot compute from public pages is everything around it: payment processing fees per method, payout and refund fees, and the pieces our congress would need — seating, on-site activation, scanners and badge printers, and invoice customisation limited to Pro and enterprise plans — all require contacting doo and carry no published price. 8 15 16
The Venue Promoter
The core fee is on the table — 0,99 EUR je Ticket, and at paid events 0,49 EUR + 5,9% des Ticketpreises, excluding VAT, invoiced to me monthly in arrears on 14-day terms, with additional payment-provider surcharges passed through to me. But I cannot price a full night from public pages: the seating tool, the handheld scanners, activation of on-site management by doo and the invoice customisation reserved for Pro and enterprise customers are all on request, and payout or refund fees are not published. 8 10 14 15 16
The Course Provider
The fee rule is public and quoted as "0,99 EUR je Ticket sowie bei kostenpflichtigen Veranstaltungen 0,49 EUR + 5,9% des Ticketpreises (zzgl. USt.)", stated as excluding VAT, billed monthly in arrears with 14-day payment terms, a cap on early-termination compensation and a right to cancel on price rises above 5%. What I cannot compute: the payment processing fee amounts are not stated (only the pass-through of surcharges is described), and we found no public prices for the seating tool, on-site management with scanners, the extra dunning module or the Pro and enterprise plans — these run through individual contact. 8 10 14 16
The Revenue Accountant
The core fee is public: 0,99 EUR per ticket plus, for paid events, 0,49 EUR + 5,9% of the ticket price (plus VAT), billed to the organiser monthly in arrears, with payment-provider surcharges passed through, 14-day payment terms and published price-increase and termination rules. Beyond that the calculator stops: the plan names Pro and enterprise appear without prices, and the dunning module, on-site activation, scanner and printer hardware, the seating tool and customised invoices are unpriced or by individual offer; we found no public information on payment processing fee amounts, payout or refund fees. 8 14 16
The Data Protection Officer
The service fee is published exactly and charged to the organiser: 0,99 EUR per ticket plus, for paid events, 0,49 EUR + 5,9% of the ticket price, excluding VAT, invoiced monthly in arrears with 14-day payment terms and payment-provider surcharges passed through. The commonly needed remainder is unpriced: payment processing amounts, the separately chargeable dunning module, on-site activation and scanner hardware, the seating tool, and plan prices such as Pro and enterprise are all quoted only through a doo representative, so a club cannot compute the cost of an event from public pages alone. 8 10 14 15 16
The Skeptic
The terms publish exact fees charged to the organiser — 0.99 EUR per ticket and, for paid events, 0.49 EUR plus 5.9% of the ticket price, VAT excluded — with monthly billing in arrears, 14-day payment terms, and rules for price increases and early termination. Payment processing costs appear only as pass-through of acquirer surcharges, the captured pages name Pro and enterprise plans without prices, and I found no public information on the price of the seating tool, on-site activation, scanner purchase, or badge hardware — so the real cost of an event is not computable from public pages alone. 8 14 15 16

Where this could be wrong
- Evidence ages. The oldest capture behind this page is from 29 Oct 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
- Weak sourcing — Data processing agreement, Legal entity, Hosting location, Hosting options. Not confirmed on the vendor’s own pages as captured.
- AI can misread a source. Extraction and judgement are automated; a citation guarantees traceability, not infallibility. If something here is wrong, say so — no account needed, every report is decided within 5 business days, and accepted corrections are published.
