Returns and refunds

Always-on rule for returns-and-refunds  ·  Source

• Keep each return as its own record (RMA) linked to the order, with lines, reason, and state.
• Check the return window, returnable flags, and already returned quantities on the server.
• Refund from the inspection result, not from the request.
• Restock only resellable units, as a return stock movement. Quarantine damaged units.
• Refund through the original payment method with an idempotency key. Store the provider refund id.
• Never refund more than was captured. Check earlier refunds inside the transaction.
• Refund tax in proportion. Refund shipping only when the policy says so.
• A partial refund keeps the order paid for the rest.
