Return Window

Return Window is the period after delivery or purchase during which a customer may return an item for a refund, exchange, or credit under the brand's return policy.

Why it matters for ecommerce brands

Thirty days is a common US ecommerce window, and many retailers extend windows during the holiday season. Longer windows can lift conversion but bring back items that are harder to resell.

Common questions

Does the return window start on purchase date or delivery date?
It depends on the brand's policy. Starting on delivery date is fairer to customers and common in ecommerce, while some brands use the order date for simplicity. State it clearly in the policy.
