Template — E-commerce

Acceptance Criteria Checklist for E-commerce Products

E-commerce acceptance criteria must validate that features work under load, integrate correctly with payment gateways, and do not negatively impact conversion rate. A feature that works in staging but breaks at scale is not done.

Use this template to ensure every e-commerce story considers the revenue and performance implications unique to online commerce.

Template sections

4 sections covering the complete acceptance criteria workflow.

01

Conversion Impact Criteria

Stories affecting the purchase funnel include: Page load time stays under 2 seconds (Google Core Web Vitals), Above-the-fold content renders within 1 second, No new friction points added to the checkout flow, and the CTA is visible without scrolling on mobile. Test with real product data, not placeholder content.

02

Payment Gateway Criteria

Stories involving payments include: Successful payment creates order and sends confirmation, Failed payment shows clear error with retry option, Timeout handling prevents double charges, Refund flow is tested end-to-end, and Payment events are logged for reconciliation.

03

Performance Under Load

Stories must be load-tested before peak seasons: Response time under 200ms at 3x current traffic, No degradation at 5x current traffic, Graceful degradation at 10x (queue requests, show wait page), and Cart data is not lost during traffic spikes.

04

Mobile-First Criteria

E-commerce is mobile-majority: Touch targets are 44px minimum, Forms use appropriate mobile input types (numeric keyboard for quantities), Images are responsive and lazy-loaded, and the feature works on 4G connections (not just fast Wi-Fi).
