our call
Start with Recharge — highest vibe code, weakest moat.
Billwerk
While creating a basic recurring charging script using Stripe is easy, building a platform that adheres to German GoBD immutability requirements, automated EU VAT OSS calculation, and SEPA Direct Debit mandate lifecycle management is extremely difficult. Replacing Billwerk with LLM code introduces severe audit and legal liability in Europe.
you can rebuild
- Hosted self-service customer portal for plan upgrades and cancellations
- Basic recurring plan catalog and pricing tiers
- Webhook notifications for invoice generation and subscription status change
- Simple automated credit card retry schedules for failed payments
- Standard checkout widgets for subscription signups
what you lose
- GoBD-compliant immutable financial audit logging and invoice archiving
- Native DATEV format exports for German tax advisors and local ERPs
- Automated EU VAT calculation and One-Stop-Shop (OSS) tax reporting
- SEPA Direct Debit XML generation, mandate management, and pre-notifications
- Pre-integrated native European payment gateways like Unzer, Adyen, and Payone
real moats
- Deep regulatory compliance with strict European accounting standards (GoBD, EU VAT OSS)
- Turnkey integrations with legacy EU accounting software like DATEV
- High data migration switching costs involving tokenized SEPA mandates and vaulted cards
Recharge
Generating subscription contracts and running a skip/swap customer portal using Shopify's native APIs is completely trivial for an AI agent. However, replacing Recharge's advanced dunning algorithms, carrier-compliant SMS workflows, and complex retention tools requires serious engineering and operational overhead.
