In typical retail POS sales, it’s valuable to prevent partial payment when making a sale.
This might happen as an error, for example, $15 is the total and the customer hands over $20, but the sales clerk incorrectly enters $2 cash and clicks Submit. The transaction proceeds with an amount owing. This is a bad idea in a retail POS situation.
My POS Profile already has only cash and credit card as Modes of Payment.
Is there a way to prevent partial payments?
