A guest wants to pay half in cash and half by QR

Choose SPLIT on the payment screen and enter the cash amount and the QR amount. The screen will not let you past unless they add up to the bill, which is what stops a half-recorded payment.

Why it matters afterwards

Each part is posted to its own account, so the Sales Report's Cash / Card / UPI figures stay true and the shift reconciles at day close. A split recorded as one lump is the commonest reason a drawer count disagrees with the system.
