Open Account (O/A) Payments
What are open account payments?
Open account payments are payments posted against one or more outstanding invoices. They may be in the form of cash or credit card, a credit on the account by your store, or by an order deposit. Any outstanding balance can be checked quickly just by looking at the customer information on the Add/Change Customer window.
Working with open account payments
You can post payments to an outstanding customer account through the Point of Sale module, incorporating other transaction types and automatically searching for outstanding account activity, or as an individual transaction from the Modules menu. Either way you choose, you have the option to post full or partial amounts to one or more invoices.
