The problem

You don't want to build this yourself.

Plans, day-accurate proration, sequential invoice numbers, dunning logic — building that yourself costs weeks and adds nothing to your product. Florentin delivers it ready-made; payments go through your Stripe integration.

  • Implement plans, trials and day-accurate proration yourself
  • Legally compliant, sequential invoice numbers and PDF receipts
  • Settle up- and downgrades mid-cycle cleanly

Does Florentin replace Stripe Billing?
