Prototype first · pay after
Payments and billing, done right.
Stripe integrations, subscriptions, usage-based billing, and marketplaces — built correctly so revenue flows reliably and the edge cases don't bite you.
Book the call → a working prototype of your checkout or billing flow within 24 hours. $0 until you've seen it.
The real problem
Payments are the one system where 'mostly works' means losing money quietly — failed webhooks, double charges, subscriptions that cancel but keep billing, payouts that don't reconcile.
Stripe's API is excellent. It's also enormous, and the difference between a demo integration and a correct one is exactly the edge cases you haven't hit yet: proration, dunning, disputes, tax, refunds mid-cycle.
We design for those cases up front — proration, dunning, disputes, refunds — because that's what billing engineering is. Revenue flows, and finance stops finding surprises.
The deal
You see it before you pay for it.
Book the call and brief us. Within 24 hours you get a working prototype of your checkout or billing flow — free. If it's not obviously right, walk away owing nothing. If it is, we scope the full build with a fixed quote.
What you actually get
Everything it takes to ship. Nothing it doesn't.
Subscriptions done properly
Plans, trials, upgrades, proration, cancellation flows — the whole lifecycle, correct.
Usage-based billing
Metering, aggregation, and invoicing that charge exactly what was used.
Marketplace payouts
Multi-sided flows with Stripe Connect — onboarding, splits, payouts, reconciliation.
Bulletproof webhooks
Idempotent handlers, retries, and monitoring — the failure modes handled before they happen.
Migration without downtime
Moving billing systems with revenue mid-flight — carefully, reversibly.

Before you ask
Questions you're probably asking.
Do you only work with Stripe?
Stripe is our default and deepest expertise; we also work with adjacent stacks (Paddle, Lemon Squeezy) when the business model fits better. The engineering discipline is the same.
Can you fix an existing integration?
Yes — that's a billing rescue, and it's squarely in scope. We audit what exists, stabilize the dangerous parts first, then rebuild incrementally without interrupting live revenue.
How do you handle migrations with live subscribers?
Staged and reversible: parallel-run the new system, migrate cohorts, reconcile at every step. Nobody gets double-charged and nobody silently churns.
What does it cost?
Fixed quote after we map your billing model on the call. Considerably less than a billing incident.
Every day billing is wrong, it's wrong with your revenue.
