- Stripe-based subscription businesses auditing MRR
- Worth noticing
- It normalises six-month and two-year billing intervals instead of treating prepaid invoices as recurring monthly revenue.
Field notes
The homepage demonstrates the product with a customer ledger whose movements total €649, including a six-month prepaid plan divided into monthly value and a discount ending without a direct event. Its workflow mirrors subscriptions, prices, coupons, invoices, and events, while retaining archived prices and an append-only event log. The service says it rejects write-capable Stripe keys and exposes judgement calls such as trial and past-due treatment as settings.
