Fakturia vs Frisbii (formerly billwerk+)

Fakturia

The whole lifecycle is modelled in the product: minimum terms, automatic renewal, notice periods with deadline calculation, trial periods that convert or end automatically, upgrades and downgrades prorated to the day, and a whitelabel self-service portal with a cancellation button built to § 312k BGB. Usage-based billing, multiple articles per contract and multiple currencies are on the feature list. I found no public information on metering through the API, ramps, quotes that convert into subscriptions, or a per-customer subscription history.

Frisbii (formerly billwerk+)

The subscription lifecycle is documented in real depth — pending, trial, active, on-hold, cancelled, non-renewing and expired states, scheduled actions, and renewal and change events exposed through the API documentation. Plans carry add-ons, one-off charges and credits, usage-based and hybrid pricing on the Growth and Scale plans, contract management, and a self-service customer portal with upgrades and downgrades. I found no public information on quotes converting into subscriptions, metering through an API, or price changes rolled out with grandfathering, which keeps it below the top band.

Fakturia

Invoices are issued as ZUGFeRD and XRechnung — a readable PDF with the XML embedded — and all data is archived GoBD-conform and audit-safe, with cancellations and corrections transferred as counter-bookings instead of edits and exact service periods printed on each line. The German B2B e-invoicing obligation from 2025 is addressed and the booking data exports to the accountant. I found no public information on Peppol delivery, sequential numbering, or e-invoicing mandates outside Germany.

Frisbii (formerly billwerk+)

Invoices are generated and archived as PDFs with automatic numbering, configurable prefixes and reset rules, and every correction runs through a credit note that leaves the original invoice untouched — the discipline a tax auditor expects. Structured e-invoicing to the EN16931 profile is implemented as Factur-X 1.0.07 / ZUGFeRD 2.3, and it extends to credit notes as PDF+XML. I found no public information on XRechnung or Peppol sending, GoBD-compliant unalterable archiving, or the e-invoicing mandates in named countries.

Fakturia

A VAT ID check, reporting data for the German summary return (ZM) and for MOSS/OSS on EU digital services are documented, and the vendor's own guidance covers reverse charge for EU services. I found no public information on automatic VAT rates per customer country and product type, VIES as the named validation source, or evidence of customer location being kept on file.

Frisbii (formerly billwerk+)

VAT is determined automatically by customer country — a standard setting covering the top twenty European markets — with reverse charge for EU business customers whose VAT number is configured, and exemption texts printed on the invoice in the customer's language. The German rate cuts are handled from a key date with automatic splitting of continuous services, and the end-of-performance-period rule is exactly how subscriptions should be taxed. I found no public information on VIES validation of VAT IDs, OSS reporting data, or US sales tax.

Fakturia

Collection is provider-flexible — SEPA direct debit collected in-house or handed to a provider, plus Stripe, Adyen, Unzer and PayPal — with bank reconciliation via finAPI and return debits processed automatically. Dunning is multilevel and automatic, with unlimited escalation stages, individual texts per stage, the original invoice attached, and it is included in every tariff. I found no public information on smart retries, card updaters, service suspension rules, handover to a collection agency, or export of stored payment details.

Frisbii (formerly billwerk+)

Payment failures are classified — temporary errors such as an exceeded limit are retried automatically, permanent ones like an expired card trigger dunning immediately — and the dunning plan's intervals and actions are configurable, with automatic cancellation as an end state and SEPA direct-debit returns handled separately. Fifty-plus European payment methods run through one gateway, and a beta AI collections agent contacts customers and records promises to pay under user oversight. I found no public information on card updaters, a handover to a collection agency, or a documented migration path for subscriptions and stored payment data.

Fakturia

The accounting handoff is the strongest part: passive revenue deferral is calculated and dissolved month by month straight into the DATEV export — a 1.200 EUR annual fee becomes 200 EUR in October and 100 EUR in each following month — through a certified direct connection to the DATEV data centre, with invoice PDFs and booking records pushed together, individual debtor accounts or a central receivables account, and a Lexware CSV alternative. A REST API with OpenAPI specification and webhooks for contract start, payment, cancellation and dunning is documented, plus a JSON data export. I found no public information on MRR, ARR or churn reporting, and CRM connections run through Zapier.

Frisbii (formerly billwerk+)

The DATEV export is what I would close the month with: SKR03 or SKR04 chart of accounts, EXTF format, per-transaction posting keys, automatic debtor IDs, and a separate revenue account per tax country, tax rate and currency, delivered monthly, weekly or daily and shippable to SFTP. MRR, ARR, churn and receivables sit on dashboards, subscription events are documented in the API, and the end of an invoice item's performance period can be exported per line. I found no public information on deferred revenue schedules, IFRS 15 recognition, or a complete export of customer and subscription data, so billing is not yet provably the system of record.

Fakturia

Fakturia comes from a Munich-registered German GmbH that describes itself as privately held without foreign investors, and runs in a TÜV-certified Nuremberg data centre with no data transfer to third countries stated. The terms require a data processing agreement and document data return and deletion after termination. I found no public information on ISO 27001 or SOC 2 certifications or a subprocessor list covering the billing chain itself, and the vendor's own website uses US providers such as HubSpot chat and Wordfence (standard contractual clauses stated for the latter).

Frisbii (formerly billwerk+)

The contracting entities are German — Frisbii Germany GmbH registered in Frankfurt with a German VAT ID, and a data protection officer in Bad Vilbel — and a data processing agreement is published in four languages with GDPR commitments in the terms. Website subprocessors are listed with their locations and safeguards, but I found no public information on where the billing platform itself is hosted; the terms name Salesforce as subcontractor only for the Salesforce-deployed product, and no security certifications are stated.

Fakturia

For the FLEX series the annual cost is computable: no base fee, 1,9% or 2,4% of monthly net revenue depending on tier, each additional user 25,- € a month, API calls beyond the included 7.500 at 0,004 € each, all prices net of statutory VAT, monthly with four weeks' notice, and an optional one-time 1.200 EUR onboarding. I found no public information on prices for the Business and Enterprise tariffs or on payment-provider pass-through fees, so a full-range computation is not possible from these pages.

Frisbii (formerly billwerk+)

Starter at €49/mo and Growth at €299/mo are public with the scaling rule — a 0.95% charge on processed billing, with billing free for the first three months on Starter — plus VAT treatment and cancellation terms. Standalone payments are €0.08 per transaction plus payment-method fees that are not itemised in what I read, and both Scale tiers are tailored pricing on a sales call, with merchant bank processing and card import fees mentioned but unquantified. I can budget the lower tiers precisely but not compute a full annual cost at the top end.
