How to Build a Subscription Billing Engine for Your B2B Platform
If you are designing a B2B subscription billing engine, get the close and reconciliation model right before you chase product flexibility. A durable sequence is to define recurring billing scope (plans, billing periods, usage, and trials), then map settlement and payout reconciliation to transaction-level settlement outputs, and finally tie that discipline into month-end close controls. The real test is simple: finance should be able to trace invoices, payments, and payouts from source events through settlement records into reconciled close outputs without ad hoc spreadsheet rescue.
