You can make changes to a recurring invoice if the last iteration is in the current period. An iteration is the chance for an invoice to be paid.

In accrual basis accounting, if you have a recurring invoice with its last iteration in a closed period, the program reverses the invoice in the current period. A copy of the invoice is created and you can edit it. Any changes you make are reflected in future iterations of the invoice.

In cash basis accounting, if you have a recurring invoice with its last iteration in a closed period, you can modify the invoice before receiving payment.
