An e-commerce PRD template must include payment failure handling, inventory edge cases (out of stock, partial fulfillment), tax and shipping calculation logic, returns and refunds flow, and conversion metrics as success criteria. Generic PRD templates treat all features as equivalent; e-commerce features have specific failure modes (an abandoned cart at payment, a botched refund, a tax miscalculation) that cost money directly. This template prevents those failures by documenting the decisions before engineering writes a line of code.

1 to 10. Standard sections

Use the standard 10-section PRD template as the base. For e-commerce features, the success metrics section (section 4) must use conversion metrics, not engagement metrics.

Conversion metrics for section 4 (required for e-commerce PRDs)

Metric Baseline Target Timeframe

Add-to-cart rate [Current %] [Target %] 30 days post-launch

Checkout initiation rate [Current %] [Target %] 30 days post-launch

Checkout completion rate [Current %] [Target %] 30 days post-launch

Payment failure rate [Current %] [Target %] 30 days post-launch

Average order value [$X] [$X+Y] 60 days post-launch

Metric	Baseline	Target	Timeframe
Add-to-cart rate	[Current %]	[Target %]	30 days post-launch
Checkout initiation rate	[Current %]	[Target %]	30 days post-launch
Checkout completion rate	[Current %]	[Target %]	30 days post-launch
Payment failure rate	[Current %]	[Target %]	30 days post-launch
Average order value	[$X]	[$X+Y]	60 days post-launch

11. Payment handling

Payment methods supported: [Credit/debit (Visa, Mastercard, Amex), Apple Pay, Google Pay, PayPal, buy-now-pay-later (Klarna / Afterpay), bank transfer, state which are in scope for v1]

Payment processor: [Stripe / Braintree / Adyen / Square, state the processor and what changes, if any, this feature requires]

Soft decline handling: When a card is soft-declined (insufficient funds, velocity check), show a specific error message and offer to try a different card. Do not show a generic error. Log the decline reason for analytics.

Hard decline handling: When a card is hard-declined (card reported stolen, fraud), show a generic "payment could not be processed" message. Do not indicate that the card is flagged. Log for fraud review.

3DS (3D Secure) authentication: [Required for EU users under PSD2. State how 3DS challenges are handled in the checkout flow, inline modal or redirect?]

Payment retry logic: [Allow user to retry with same card? Different card? After how many failed attempts does the order cancel?]

12. Inventory edge cases

Out of stock at checkout: If an item goes out of stock between add-to-cart and checkout submission, show an inline error at checkout, do not allow the order to complete. Offer: remove the item, or save to wishlist and be notified.

Partial fulfillment: If a multi-item order has one item out of stock at fulfillment time: [ship available items immediately and ship remainder when in stock / cancel out-of-stock item and refund / hold entire order until all items available, state the policy]

Oversell protection: [State the mechanism that prevents selling more units than available, database lock, pessimistic inventory reservation at add-to-cart, or optimistic check at payment capture]

Pre-order inventory: [If applicable: how is pre-order inventory tracked, what happens if pre-order demand exceeds supply, and how are customers notified of a delay?]

13. Tax and shipping calculation

Tax calculation: [TaxJar / Avalara / manual rates, state the provider. State which jurisdictions require tax collection. State how tax is displayed: included in price vs. added at checkout.]

Shipping calculation: [Flat rate / weight-based / real-time carrier rates (FedEx, UPS, USPS), state the method. At what cart value does free shipping apply?]

International shipping: [Supported / not supported for v1. If supported: which countries? Who is responsible for customs declarations? Duty and import tax responsibility: seller (DDP) or buyer (DDU)?]

14. Returns and refunds flow

Return window: [30 days from delivery, state the policy]

Return initiation: [Self-serve via order history / contact support, state which is in scope for v1]

Refund processing time: [3 to 5 business days to original payment method, state the SLA]

Restocking fee: [None / X%, state the policy]

Non-returnable items: [Digital goods, personalized items, final sale, list explicitly]

Frequently asked questions

What metrics should I use as success criteria in an e-commerce PRD?

E-commerce PRDs should use conversion funnel metrics, not engagement metrics: add-to-cart rate, checkout initiation rate, checkout completion rate, payment failure rate, and average order value. Each should include a current baseline, a specific target, and a measurement timeframe. 'Improve checkout experience' is not a metric, 'increase checkout completion rate from 61% to 74% within 30 days of launch' is.

How should payment failures be handled in an e-commerce PRD?

Separate soft declines (insufficient funds, velocity checks) from hard declines (stolen card, fraud). Soft declines: show a specific, helpful error message and offer to try a different card. Hard declines: show a generic 'payment could not be processed' message, never indicate the card is flagged. Both require separate error messages, separate logging, and separate analytics events. Treating all declines identically creates a worse UX and harder debugging.

What is oversell protection and how should it be documented in a PRD?

Oversell protection is the mechanism that prevents selling more units than you have in stock. The three approaches are: pessimistic reservation (lock inventory at add-to-cart), optimistic check (check at payment capture only), and hybrid (soft lock at cart, hard check at payment). Document which approach you're using because it affects database design, cart expiry logic, and the user experience when items go out of stock between steps.
