Where the guest pays
Identify counter service, table service, takeout, delivery, and online orders separately. The equipment, software, and cost assumptions may differ. A portable terminal does not by itself confirm a complete table service workflow.
Tips, checks, and refunds
If you need tips, split checks, open tabs, or adjustments, have each function demonstrated in the proposed setup. Verify how receipts and refunds are recorded. Do not assume a hardware family includes every restaurant application.
Orders and existing software
Name the POS, online ordering tools, and delivery platforms. Confirm each required connection and whether order and payment records remain consistent. An accounting connection does not establish kitchen display or delivery integration.
Compare a representative service period
Bring processing statements and separate POS, gateway, and ordering bills. Check total cost at your average check size, staff permissions, connectivity, support, and equipment terms. Test a sale, decline, and refund before service relies on the replacement.
