Prepare product information and unit economics, connect a suitable payment flow and verify payment, fulfillment, refunds and customer recovery before release.
Choose the products, variants and inventory model. Write accurate descriptions, images, availability, shipping/collection information and customer-support contacts. Assign responsibility for stock, fulfillment, returns and account access. Select a platform based on those requirements and actual operating costs, rather than a universal launch schedule or free-tier assumption.
Define one unit or a justified fixed sales mix and the accounting period. Record net sale proceeds, variable product and fulfillment costs, and fixed period costs without double counting fees or shipping. Use Break-Even for the resulting contribution model. Keep taxes, refunds and inventory cash commitments explicit; the threshold does not forecast orders or cash flow.
Use the platform or payment provider’s supported integration and test environment. Confirm product identifiers, quantities, totals, currency, shipping choices and confirmation behavior. Keep secret credentials and trusted price decisions on the appropriate server. Make checkout, error messages and recovery usable with a keyboard and a narrow viewport. Review your remaining payment and data obligations with the provider.
For an automated integration, verify payment status through the provider’s trusted server-side mechanism and validate webhook signatures. Record an order’s fulfillment state and handle duplicate or concurrent notifications without fulfilling it twice. Account for delayed payment success or failure, cancellation and refunds. A return to the success page alone is not reliable proof that fulfillment should occur.
In the provider’s test mode or sandbox, exercise successful payment, decline, abandoned checkout, duplicate notification, delayed status, unavailable stock and refund handling as applicable. Verify customer messages, access or shipping work, inventory changes and administrative records. Inspect one pasted redacted response block when troubleshooting delivery headers, while keeping credentials and customer data out of shared logs.
Confirm production configuration through the normal release process and verify public product, cart, support and policy paths. Monitor payment and order failures and reconcile orders, fulfillment, refunds and payouts for a stated period. Add supported product structured data that matches visible information and validate it without promising a rich result. Download the release and reconciliation record.

Stripe documents using trusted payment state and handling repeated or concurrent fulfillment calls. A customer return URL cannot replace reliable payment-event handling.
Use Stripe’s documented test environments and simulated payment details for integration checks. Apply equivalent documentation when using another provider.
Google requires structured data to follow its policies and reflect page content. Valid markup does not guarantee a rich search result.
Keep these task-specific records with the tested version and review date.
| Record | Include | Verify |
|---|---|---|
| Payment | Order/session identity, amount and trusted payment state | Success, decline and delayed state |
| Fulfillment | Recorded status and idempotent processing | Duplicate/concurrent event does not duplicate delivery |
| Operations | Inventory, customer messages, refund and payout records | Reconcile the whole order lifecycle |
A completed payment, fulfilled order, refund and payout are separate events to track.
Use clearly labeled sandbox orders so operational staff can distinguish integration checks from real customer work.
