Payments & billing systems

The boring half of payments is the whole job

A billing feature starts as one invoice. Then come subscriptions, payouts, refunds, disputes, and ACH that clears three days later. The boring parts are where the money lives.

draft to disputed, all handled

Card + ACH

connected Stripe accounts

Correctness

over speed, every time

We build payments and billing into the platforms other companies run on. Customers and patients get billed. Providers connect their own Stripe account and get paid out. Plans renew, upgrade, and prorate. Invoices go from draft to disputed and still reconcile.

We deliver this regularly, across healthcare and SaaS, down to the invoice state machine with every unglamorous state. Each state is a place money can quietly 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.

Customers pay, providers get paid, plans renew

  • Customer and patient billing: one-off charges, payment links, card and ACH, saved payment methods.
  • Subscriptions and tiered plans, with proration, upgrades, downgrades, and dunning when a card fails.
  • Stripe Connect for marketplaces and multi-party payouts: providers onboard their own account and get paid out.
  • An invoice state machine that survives partial payments, refunds, voids, and disputes.
  • Idempotency and retry logic, so a timeout never charges a customer twice.
  • Reconciliation that ties out, because the books have to match the bank.

Why correctness beats speed here

You can ship a fast payments feature or a correct one. 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 the money sits next to patient data, we build it HIPAA-aware, money and PHI held to the same standard.

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.

What buyers ask before they start

Do you build on Stripe?

Yes, including Stripe Connect for marketplaces and multi-party payouts, card and ACH, subscriptions with proration and dunning, and an invoice state machine that survives refunds, voids, and disputes. We add idempotency so a timeout never charges a customer twice.

Why does a payments build cost more than wiring up a checkout button?

The button is the demo. The product is everything after it: partial payments, failed cards, ACH that clears three days later, and books that have to reconcile to the bank. That is where the work and the risk live.

Can you build payments into a HIPAA platform?

Yes. When money sits next to patient data, we hold both to the same standard and build it HIPAA-aware. Correctness over speed, because a double charge is not a bug ticket, it is a refund and a trust problem.
