The boring half of payments is the whole job
A billing feature starts as a simple invoice tool. Then it becomes a state machine with disputes, refunds, and ACH. The boring states are where the money lives.
8 states
draft to disputed, all handled
Card + ACH
connected Stripe accounts
Correctness
over speed, every time
On a healthcare platform we built billing that started as a simple invoice tool. It became a real payments system: connected Stripe accounts, card and ACH, and an invoice state machine with every unglamorous state. Draft, sent, unpaid, partially paid, refunded, voided, disputed. Each one is a place money can go wrong.
Payments is where "simple" features are never simple. The demo is a button. The product is what happens after the button when the network times out.
What we build into payments
- Stripe Connect for marketplaces and multi-party payouts.
- An invoice state machine that survives partial payments and disputes.
- Payment links, scheduling breakdowns, and reconciliation that ties out.
- The idempotency and retry logic that keeps you from charging twice.
Why correctness beats speed here
You can ship a fast payments feature or a correct one, and in healthcare and finance the correct one is the only one that counts. We ship on a tight deadline without cutting the safety corners, because the cost of a double charge is not a bug ticket, it is a refund and a trust problem.
When not to hire us
If a hosted checkout link covers your whole flow, take the link. You do not need a custom payments build to sell one thing at one price. Call us when the flow has more than one party, more than one currency, or more than one way to go wrong.
