Subscription and Recurring Billing Engine
A build-to-order SAP Business One add-on that turns contracts into scheduled A/R Invoices with proration, usage-based charges and deferred revenue schedules. ECOSIRE builds it for your billing rules after a fixed quote.
- Contracts held as User-Defined Objects with User-Defined Table backing, linked to Business Partners and visible to standard SAP Business One find, browse and authorisation behaviour
- Contract lines referencing real Items or service descriptions, supporting flat recurring, quantity-driven, one-off scheduled and usage-rated charge types
