Partial fulfillment means completing only some items or quantities while the rest remain open, cancelled or backordered. Track every line separately. ### Can part of an order be fulfilled? Yes. Fulfill the available line items or quantities and leave the rest open with a clear next step and customer-visible status. ### Can part of an order be cancelled? Yes. Cancel exact unfulfilled items, release their stock and adjust the payment without changing items that will still ship. ### Can part of an order be refunded? Yes. Refund no more than the eligible value of the affected items and approved shipping or tax adjustment, while preserving the remaining paid balance. ### Can part of an order be returned? Yes. Create the return against exact fulfilled quantities so the system does not allow more units back than the customer received. ### How should customers see partially fulfilled orders? Show each item and quantity as fulfilled, shipped, cancelled, returned or still pending. Include separate tracking or refund information where outcomes differ. ### How should partial orders affect inventory? Reserve, release and receive stock at line-item and quantity level. Never restore the entire order when only one unit was cancelled or returned. --- ## Frequently asked questions ### Can one item be refunded without cancelling the order? Yes, if the payment provider and order system support a partial refund and the remaining order total stays accurate. ### How should customers see a split outcome? Show each item, quantity and current state, with separate shipment, refund or return details when needed. --- ## Related learning path - **Ecommerce Order Cancellation** - **Customer Order History and Guest Lookup** - [ZenBasket Build Guide](https://help.getzenbasket.com/zenbasket-builder/)
