How to Process a Partial Receipt Refund After loading the original receipt into the refund workflow: Review all eligible receipt lines. Delete every item that is not being returned. For a multi-quantity line, keep only the quantity actually returned. Confirm the refund total, tax, discounts, and tender. Complete checkout and provide the refund receipt. RepairNest POS tracks refunded quantity. A product line can be refunded only up to the quantity originally sold; a fully refunded item cannot be refunded again.
