Stripe Checkout, integrated the Starks Enterprise way
This page demonstrates the Stripe Checkout flow we integrate into client storefronts under SOW SE-SOW-13. It is the exact same pipeline that powers secure sign-then-pay checkout on starksenterprise.com — server-computed amounts, session-backed payment state, and webhook-verified fulfillment.
The checkout flow
- Agreement first. The customer e-signs the SOW and Payment Agreement (DocuSign) before any payment is unlocked.
- Server-side amount lock. Prices are recomputed on the server from the estimator inputs — the browser never sends an amount it invented.
- Stripe Checkout Session. A single-use session is created with line items, state-aware sales-tax treatment, and success/cancel return URLs.
- Hosted, PCI-scoped payment page. Card data goes straight to Stripe's hosted page — it never touches our servers.
- Webhook-verified fulfillment. Access and receipts are granted only after Stripe's signed
checkout.session.completedwebhook is verified server-side.
