Frisbii (formerly billwerk+) vs Stripe Billing

Frisbii (formerly billwerk+)

Plans, add-ons, discounts and coupons, trials, usage-based and hybrid pricing and a self-service customer portal with upgrades and downgrades are all documented, and the lifecycle is modelled end to end through named states from pending to expired, with scheduled actions, pause and trial flags. For our upcoming usage-based tier that covers most of what I need. We found no public information on quotes converting into subscriptions, multiple currencies and price books, metering through an API, or price changes rolled out to existing customers with grandfathering.

Stripe Billing

Seats, volume and graduated tiers are configurable in the Dashboard without code, with trials, quotes, proration, multi-phase subscription changes, a hosted customer portal, and basic usage metering through the meters API with up to 100 million events a month included; the advanced usage-based product Metronome is sold separately at custom pricing. The catch for me is that a product and price can only be edited until a subscription is created, which makes rolling price changes to existing customers harder than it should be.

E-invoices go out as Factur-X 1.0.07 / ZUGFeRD 2.3 on the EN16931 profile for both invoices and credit notes, numbering is automatic with configurable prefixes and reset rules, and corrections happen by credit note with its own configurable number sequence while the original invoice stays unchanged. Invoices are generated and archived as PDFs, with DIN5008 compliance warnings on invoice formatting. We found no public information on XRechnung, Peppol sending, or GoBD-compliant unalterable archiving, which is what a German audit would ask me for.

Stripe Billing

The captured documentation states that Stripe Invoicing does not itself generate or transmit legally compliant e-invoice files — that runs through third parties such as Billit from the App Marketplace — and I found no public information on sequential numbering, mandatory invoice content, or retention and archiving on the captured pages. Credit notes are handled correctly (not modifiable once issued, multiple per invoice, refund or customer balance), and invoices go out in over 135 currencies and 35 languages.

VAT is determined automatically by customer country with preset normal rates for twenty top European countries, reverse charge applies to cross-border EU business customers when a VAT number is configured and the tax setting enables it, non-EU deliveries print at 0% with an exemption text, and German rate-change dates with service-period splitting come preset. Invoices follow the customer's language and exemption texts are translatable. We found no public information on VIES validation of VAT IDs, OSS reporting data, or US sales tax, and reverse charge relies on my own configuration rather than any validated check.

Stripe Billing

Stripe Tax covers calculation across more than 90 countries with product tax codes, threshold monitoring, historical liability analysis, and registration and filing directly or through partners, applying to one-off and recurring payments even outside Stripe. For my nine EU countries the engine looks real, but I found no public information on reverse charge, VAT ID validation or OSS reporting on the captured pages, and registration and filing are marked as costing extra.

Failed payments are retried automatically on temporary errors with smart failure classification while dunning starts immediately on permanent ones, and I control the dunning plan's intervals and actions up to automatic cancellation and reminder emails — exactly the retry-before-churn behaviour I care about. One gateway covers fifty-plus European payment methods, SEPA direct debit includes return handling, a beta AI collections agent chases unpaid invoices and records promises to pay, and a receivables dashboard tracks collection performance. We found no public information on card account updaters, bank-transfer reconciliation, handover to a collection agency, or a documented migration path for subscriptions and payment tokens.

Stripe Billing

This is the strongest area: Smart Retries with AI-chosen timing (recommended default of 8 attempts within 2 weeks), custom retry schedules of up to three retries, segment-specific retry policies, updates for expired cards, payment reminder emails, automatic bank-transfer reconciliation, and subscription outcomes from pause to cancel after failures, with the vendor reporting 8.2 billion dollars recovered in 2025. Over 100 payment methods including direct debits are supported, and there is a documented path for migrating SEPA direct debit mandates in from another provider; I found no public information on a collection-agency handover or on exporting payment details out.

MRR, ARR and churn sit on dashboards alongside billing, receivables and customer-health views, and the accounting handoff is properly German: DATEV export with SKR03 and SKR04 charts, posting-key overrides, automatic debtor IDs, revenue accounts per tax country, tax rate and currency, and delivery to SFTP, OneDrive or Google Drive on daily, weekly or monthly intervals. API documentation with subscription events and a Salesforce app round it out. We found no public information on deferred-revenue schedules or revenue recognition, a complete export of customer and subscription data, or data-warehouse sync.

Stripe Billing

Revenue recognition to ASC 606 and IFRS 15 is stated (at extra cost), with six report types including debit and credit by customer, product and invoice, general-ledger codes, open-period handling, CSV and API access, plus named accounting integrations (QuickBooks Desktop IIF export, NetSuite connector) and data-warehouse sync. The recognition API is in public preview with fields that may change, and I found no public information on a DATEV export.

The contracting entities are German — Frisbii Germany GmbH in Frankfurt and Frisbii Media GmbH in Kempten, with register numbers and German VAT IDs — and a data processing agreement is published in four languages with a German data protection officer, GDPR clauses and standard contractual clauses for third-country providers. However, the hosting location of the core billing platform is not described on the captured pages: only the Salesforce-hosted app names its host, the marketing website runs on a US WordPress provider, and we found no public information on a platform subprocessor list or security certifications.

Stripe Billing

An Irish entity in Dublin is named in the imprint with a registration number and VAT ID, an EEA entity is authorised by the Central Bank of Ireland, a data processing agreement and a subprocessor list are published, and ISO 27001 and SOC 2 are stated. The parent company is US-based, I found no public information on where billing data is hosted, and the captured facts do not show subprocessor locations.

Starter at €49/mo and Growth at €299/mo are published with a 0.95% charge on processed billing, seat counts, VAT treatment and cancellation terms, and the payment service standalone is €0.08 per transaction plus method-based fees — enough to compute cost on the two lower tiers. But Scale and Scale for Media are "Tailored pricing Talk to sales", the media plan's variable fees per subscription, transaction and users carry no figures, and merchant bank processing and customer/card import fees are referenced without amounts, so the real annual cost at the top end is not computable from public pages.

Stripe Billing

The core rule is public and computable: 0.7% of billing volume pay-as-you-go with no recurring fees, 0.67% for additional volume above 80.000 € monthly, a 500 € annual-contract option billed monthly with an 11% saving, and card fees of 1,5% + 0,25 € for standard European cards. But a long list of things I actually need — revenue recognition, tax registration and filing, metering beyond the included events, data-warehouse sync, receivables aging, third-party gateways and Metronome — are marked as available at additional cost or at custom pricing with no price on the captured pages, and e-invoicing goes through an unpriced partner.
