Subscription Billing Flow Re-Architecture
We rebuilt the billing lifecycle from checkout to dunning so finance and product teams could manage plans without engineering tickets.
Dunning sequences and retry logic recovered failed renewals that were previously written off.
Clear proration logic and in-app previews reduced failed upgrade and downgrade attempts.
Self-serve invoices and transparent charge breakdowns reduced confusion-driven tickets.
Reconciled event logs removed manual corrections at month end.
Project Details
Problem
Billing logic was spread across UI code, cron jobs, and spreadsheets. Plan changes were error-prone and finance reporting required manual cleanup.
Approach
We centralized billing state transitions in backend services, implemented event-driven webhooks, and added an admin layer for plan management. The trade-off was stricter validation that temporarily slowed custom deal workflows.
Result
The team gained reliable billing operations with fewer support issues and cleaner month-end reconciliation.
What Could Be Better
The first version of proration rules confused sales-assisted contracts. We introduced contract templates and role-based overrides.
