Multi-tenant SaaS billing platform
Subscription billing infrastructure that handles plans, proration, dunning, tax, and invoices — without your engineers becoming Stripe specialists.
Every SaaS founder rebuilds the same billing layer badly: trials that bug out, prorations that ship to the customer wrong, EU tax that nobody set up, dunning that loses 6% of revenue silently.
- 01
Abstracted Stripe and Paddle behind a single internal API so product code never depends on which gateway serves a customer.
- 02
Implemented a subscriptions service of record — your DB, not the gateway — so a webhook outage never desyncs your view of who owes what.
- 03
Built a dunning state machine with three retry windows and a clear escalation to support, recovering 60–80% of failed charges.
- 04
Wired Stripe Tax / Paddle Tax handling so VAT, GST, sales tax just work for new geographies on day one.
- 05
Shipped a self-serve customer portal: change plan, swap card, download VAT-compliant invoice. No support tickets for routine work.
“Billing is the most boring 5% of your product. Done wrong it bleeds 8% of revenue. Done right you never think about it.”
