Payment Allocations

When a payment run creates a payment for an invoice, it automatically creates allocations against the full balance of each invoice line. However, if a user created a payment record manually, they can also make any number of allocations as long as the total allocation amounts are within the payment’s amount. In this case, an allocation can cover all or part of an invoice line’s balance.

For example, let’s say an account has an invoice with a $1000 invoice line, a $500 invoice line, and a $300 invoice line. The same account also contains an unallocated $1500 payment record. A user could make a $1000 allocation against the first invoice line and a $500 allocation against the second invoice line. They could also apply a $300 payment allocation to each invoice line, and leave the payment record with an unallocated balance for future use. One payment’s allocations can also be made to invoice lines from different invoices, as long as the invoices are on the same account.

Unallocated payments remain on an account indefinitely.

• Correct a Posted Payment in Lightning Experience
  Salesforce Billing must retain a copy of all payments for legal and accounting purposes. You can fix an error on a posted payment by refunding it. The refund reduces the erroneous credit note’s balance to zero. You can then create and post a payment with the correct values. (Salesforce Billing Managed Package)
• Payment Allocation Errors
  Sometimes, your payment run can receive a successful gateway response and create a payment, but fail to allocate the payment to your invoice. This can happen due to user-defined validation rules or database errors. To finish the allocation process, manually create an allocation record and assign it to your invoice.
