One Peak

Payments · Stripe

One Peak for Stripe integrations.

Stripe is the default way startups take money online, and the part of an MVP where edge cases actually matter: failed payments, refunds, webhooks, taxes. We build Stripe integrations that survive real customers, not just demo checkouts.

What we build with Stripe

From a simple checkout to full subscription businesses.

  • Subscriptions with trials, upgrades, and proration handled
  • Stripe Checkout and Customer Portal for fastest time-to-revenue
  • Marketplace splits with Stripe Connect
  • Usage-based and per-seat billing models

The part everyone underestimates

The checkout is 20% of the work. The other 80% is webhook reliability, dunning for failed payments, refunds, disputes, and keeping your database in sync with Stripe's truth — that's what we actually scope for.

When billing belongs in your MVP

If willingness-to-pay is the assumption you're testing, billing belongs in v1. If activation is the open question, a waitlist plus manual invoicing can defer the complexity — we'll tell you which.

Frequently asked questions

How long does a Stripe integration take?

A subscription flow with portal and webhooks: about a week inside a normal MVP build. Marketplace splits with Connect: longer — scoped explicitly.

Should my MVP use Stripe Checkout or a custom payment UI?

Checkout, almost always — it's faster to ship, handles SCA and wallets, and converts well. Custom UIs earn their cost later.

Can you set up EU VAT handling?

Yes — Stripe Tax configured for EU VAT, with invoices that finance teams and accountants accept.

Do you handle subscription changes and refunds?

Yes — upgrades, downgrades, proration, cancellations, and refund flows are part of the integration, not afterthoughts.

Is billing data safe in our hands?

Card data never touches your servers — Stripe holds it. Your database stores references and entitlements only.
