Oldest allocates the Payment Amount, along with any other existing credit amounts, toward all of the customer's outstanding invoices. The allocation begins with the oldest invoice and progresses toward the most recent, until the Payment Amount is exhausted.
:::(Error) (Example) A customer has two outstanding invoices: an older one of \$500 and a more recent one of \$1000, as well as an unallocated credit note of \$200. They then pay \$1000 toward their account. Using the **Bulk** allocation method will total the customer's credits to \$1200, and then allocate them first toward the older, \$500 invoice and then allocate the remaining \$700 credit toward the more recent \$1000 invoice, reducing its Remaining Balance to \$300. :::Transaction Age allocates the Payment Amount, along with any other existing credit amounts, toward all of the customer's outstanding invoices within a specified age range, depending on the customer's payment terms. The allocation begins with the oldest invoice within the specified age range and progresses toward the most recent, until the Payment Amount is exhausted. An invoice's age is measured in the amount of payment periods that have elapsed since the accounting date of the invoice and is shown in the Age column of the Allocations list. The transaction age range is determined using the From Age and To Age textboxes that appear at the bottom of the Bulk Allocation Options window once the Transaction Age toggle has been selected.
