What Is the Register? Navigation: Open Register from the main navigation. The register is where employees build a cart and complete a sale or refund. The screen brings together customer selection, Sale/Refund mode, product search, cart items, receipt notes, customer notes, discounts, tax, totals, Hold, Cancel, and checkout. The register supports fast scanner-based selling as well as manual entry. You can find stocked products by identifiers, search by name, or enter a miscellaneous item when no inventory product should be used.
