If a Customer owes for example $10 000-00 on several invoices and over a period of 60 days. He now pays $7000-00. Can I allocate this amount to credit from the oldest invoices to the newer invoices on bulk credit?
Allocate the receipt to Customer credits account and the customer’s subaccount. Manager will automatically do what you want. When it runs out of money, you may have a partially paid invoice, with the remaining ones being unpaid.
