Finance Operations
Early accessFinStackX
Subscriptions, usage-based pricing, and invoicing as infrastructure, so finance teams stop reconciling by hand.
FinStackX is a billing engine that software products embed. It handles plans, the full subscription lifecycle, invoicing with proration, coupons, usage records, refunds, and failed-payment retries, with tenant isolation and an audit trail on every change. We are building it to run billing for our own products first.
The core billing engine is built. Payment gateway integration and PDF invoices are next.
