PAYMENTS · STRIPE + MOREPayments that reconcile.
Stripe and other processors behind one clean abstraction, with idempotent capture, refunds, webhooks, and reconciliation. We have shipped multi-processor payments in production.

[THE SHORT VERSION]
The money has to tie out, every time.
Payments look simple in the demo and get hard in production: idempotency, webhook reliability, partial refunds, disputes, and reconciliation against the processor. We treat payments as a state machine with an audit trail, and we have run several processors behind one abstraction (see the Nuforce case).
When it fits
- Subscriptions, marketplaces, and one-time payments
- Products needing multiple processors behind one interface
- Anywhere money movement must reconcile and audit cleanly
[HOW WE BUILD IT]
How we build with Stripe & Payments.
02
Build on a tested foundation
We integrate Stripe & Payments against a foundation we trust: typed code, CI, and observability from the first commit. Boring infrastructure, modern surface.
03
Eval before launch
An eval suite proves the build behaves before it reaches a user. We measure, then ship.
04
Handoff with ownership
Your team gets the code, the tests, and a runbook. No lock-in to us or to a vendor framework.
