Frisbii (formerly billwerk+) vs Stripe Billing

Frisbii (formerly billwerk+)

Add-ons, trials, three documented upgrade and downgrade paths, usage-based and hybrid pricing models and a self-service customer portal are all evidenced, with the full lifecycle from pending through trial, on-hold and non-renewing to expired handled by the system. I found no public information on proration at mid-period changes, metering through an API, quotes that convert into subscriptions, or multi-currency price books, and entitlements appear only in the Scale tier's feature list.

Stripe Billing

Seat, tiered, graduated and volume pricing are documented for both Dashboard and API, usage metering runs through the Meters API with up to 100 million events per month included, and free trials, quotes, a Stripe-hosted customer portal and multi-phase subscriptions that schedule future changes are all evidenced. On grandfathered price rollouts, entitlements exposed to the selling application and versioned subscription history we found no public information.

Hybrid e-invoices as Factur-X 1.0.07 / ZUGFeRD 2.3 to the EN 16931 profile, automatic invoice numbering with configurable prefixes and reset rules, and credit notes as separately numbered documents that leave the original invoice unchanged — that trifecta is done properly, down to DIN 5008 warnings and printable VAT exemption texts. I found no public information on Peppol delivery, XRechnung for public bodies or a named-GoBD archiving guarantee; archiving is described only as PDFs being generated and archived.

Stripe Billing

Credit notes are handled the way an auditor wants: not modifiable once issued, creatable only from an invoice or an associated refund, and described as the source of truth when an invoice amount must be amended, with invoices in over 135 currencies and 35 languages. For structured e-invoices, however, the documentation itself states that Stripe creates invoice records and exposes data through API and webhooks but does not itself generate or transmit legally compliant e-invoice files — UBL, CII and Peppol BIS Billing 3.0 are reached through third parties such as the marketplace partner Billit. We found no public information on sequential numbering, mandatory invoice content or GoBD-conformant archiving.

VAT is applied automatically by customer country with the normal rates of twenty European countries preconfigured, reverse charge for EU business customers requires a VAT number to be configured, non-EU supplies go out at 0% with a printed exemption text, and German rate changes with key-date splitting are preset. The documentation stops at a VAT number being configured — I found no public information on VIES validation before 0% is applied — and the VAT-group option explicitly places the legal verification on the seller's tax adviser; OSS is assumed of the seller rather than evidenced with reporting data, and I found no public information on US sales tax.

Stripe Billing

Stripe Tax automates VAT, sales tax and GST across more than 90 countries with product tax codes, tracks sales against local registration limits, performs registrations on your behalf and manages filings directly or through integrated partners, covering one-time and recurring payments and even payments outside Stripe. What the year-end audit will ask for next — reverse charge against a validated VAT identification number, VIES checks and OSS reporting data — we found no public information on, and no written statement of which tax liability a merchant-of-record arrangement would assume.

Frisbii (formerly billwerk+)

One gateway covering more than fifty European payment methods with SEPA direct debit and return handling, retries that classify temporary from permanent failures, a dunning plan where intervals, actions and even automatic cancellation are configurable, plus an AI collections agent in beta and a receivables dashboard tracking collection performance. I found no public information on card updaters, bank-transfer reconciliation, a handover to an agency, or a documented migration path for taking subscriptions and payment tokens elsewhere; gateway choice is stated only as Frisbii or partner options.

Stripe Billing

Smart Retries with AI-chosen timing, custom retry schedules of up to three attempts, retry policies per customer segment, automatic reminder emails, cancellation or pausing of subscriptions once retries are exhausted, and automatic reconciliation of recurring invoices paid by ACH or bank transfer are all documented, with 8.2 billion dollars of failed payments recovered in 2025 reported. Over 100 payment methods and connections to other payment providers are offered (multiprocessor support marked as a paid extra), and there is a documented path for migrating SEPA direct-debit mandates from another provider. We found no public information on a handover to a collection agency or recovery figures broken down per dunning step.

MRR, ARR and churn dashboards sit on top of a genuinely deep DATEV export — SKR03/SKR04 selection, posting-key overrides, revenue accounts per tax country, rate and currency — schedulable daily, weekly or monthly to Google Drive, OneDrive or SFTP, with a named Salesforce integration and documented subscription events and API. I found no public information on deferred-revenue schedules or IFRS 15 recognition, though the exportable end-of-performance-period field shows period-based recognition is understood.

Stripe Billing

Revenue recognition to ASC 606 and IFRS 15 is stated, with six debit/credit report types including per-customer, per-invoice and per-line breakdowns carrying general-ledger codes, downloadable as CSV or through an API that automates period accounting; the handoff runs through the NetSuite connector and QuickBooks exports, and data-warehouse sync exists as a paid extra. We found no public information on a DATEV export or on a complete export of customers, subscriptions and invoices that a successor system could import, and the recognition API is a public preview whose data fields may change.

The contracting entities are two German companies with a Frankfurt register number, there is a German data protection officer, a published data processing agreement in four languages, standard contractual clauses and DPF-listed providers for third-country transfers, and website subprocessors named with their locations. The hosting of the core billing platform is not confirmed on the captured pages — the privacy notice says only that in some cases data is processed on servers in Germany and the EU — and I found no public information on security certifications or a full platform subprocessor list.

Stripe Billing

The captured pages prove an Irish contracting side — a legal notice naming an entity at One Wilton Park, Dublin with Irish registration number 564555 and VAT number IE3396855EH — plus a Central Bank of Ireland-regulated affiliate, a published data processing agreement, a published subprocessor list and stated ISO 27001 and SOC 2 certifications. But the parent vendor is US-based, and the captured pages give no information on where customer, invoice and payment data are hosted or in which countries the listed subprocessors operate.

Starter at €49/mo and Growth at €299/mo are public with inclusions and seat counts, the 0.95% charge on processed billing is stated, standalone gateway transactions are €0.08 each, and VAT exclusion plus a 3-month cancellation notice are published. But Scale and Scale for Media are tailored pricing on a sales conversation, the variable media fees per subscription, transaction and user are not quantified, and charges above the user limits sit in the ordering document rather than on the pricing page — so a buyer above Growth cannot compute an annual cost from public pages alone.

Stripe Billing

The core scaling rule is public: 0,7 % of billing volume on pay-as-you-go with 0,67 % for additional volume above 80.000 € monthly, a 1-year contract billed monthly at 500 € with 11 % savings, and card pricing of 1,5 % + 0,25 € for standard European cards. But commonly needed modules — revenue recognition, tax registration and filing, high-volume metering, multiprocessor payments, data-warehouse sync, receivables aging — are marked with an asterisk as available at a surcharge with no prices, and we found no public information on VAT treatment of the fees. A buyer can compute the billing fee but not the total annual cost with the modules that matter.
