If you're making a sale from the register then you should generally make another payment until the sale is completely paid off. If you're paying off an invoice, then the invoice will be in a partially paid state and can always be paid off later.

Incomplete sales

If you leave a partially paid sale then that sale will appear in your Invoices tab, if you are in an invoicing mode, otherwise it will appear under the Incomplete filter of the Paid tab until it is paid off.
