A sales invoice is more than a receipt printout—it is the durable record of what was sold, at what price, and under which invoice number. Cashiery keeps that history accessible after the customer leaves the counter.
Refunds happen in real retail life: a damaged gift wrap, a wrong stationery SKU, a perfume box returned unopened. Cashiery supports revisiting invoices so refunds stay tied to the original sale.
For flower shops, herbal stores, accessories counters, and packaged grocery sellers, organized invoices reduce disputes and make end-of-day reviews far less painful.
