Stripe integrations, Connect + Billing + webhooks, production-grade end-to-end.
Stripe is the default. We've shipped Connect for marketplaces, Billing for SaaS subscriptions, one-shot payments for consumer apps, and the webhook plumbing that ties them to the rest of the product. The piece most teams underestimate is the operational layer; we don't.
What we build
Connect for marketplaces and multi-party flows
Express, Custom, or Standard Connect accounts depending on platform needs. Onboarding flows with KYC up front. Transfer logic that respects platform fees, holds, and reserves. Connect Embedded Components where the platform wants its own brand on the seller dashboard.
Billing for subscriptions that survive proration
Stripe Subscriptions with the state-machine details handled: trials, plan changes, proration, schedule changes, pausing, cancellation with refund logic. Phased subscriptions for migration events. The UI shows what the customer will be charged before the charge happens.
Checkout, Payment Links, and Elements where each fits
Stripe Checkout for fast time-to-launch. Payment Links for sales-led flows. Stripe Elements when the in-product experience needs to feel native. We pick per-surface; we don't religiously force one option on every flow.
Webhook ingestion as a first-class service
Every Stripe event lands in a typed handler with idempotency, ordering guarantees, and replay support. The handler is testable in isolation; we run the Stripe CLI in CI to fire events at the dev server. Production webhooks get the same treatment as production HTTP requests.
Stripe Tax wired correctly
Automatic tax calculation on Checkout and Subscriptions. Origin and destination addresses validated; tax IDs collected where required for reverse-charge. Threshold monitoring per jurisdiction so the next VAT registration is on the roadmap before it's mandatory.
Disputes + refunds + reconciliation
Disputes route to an internal queue with the evidence template pre-filled from order data. Refunds are partial- and full-friendly with proper Stripe webhook reconciliation. Monthly reconciliation runs against the payouts report and flags discrepancies before the accountant finds them.
Where this fits
You're standing up Stripe for the first time and need the production-grade version, not the Quickstart-grade one.
Your Stripe code grew organically and the failure modes (webhook out-of-order, partial refunds, plan changes mid-cycle) are getting expensive to debug.
You're migrating from another processor and need the cutover plan that doesn't lose in-flight transactions.
