    Note: You may need to post invoices in Accounts Receivable as well, in AR, Tasks, Post Invoices.

Note: If you bill a partial retainage amount (not 100%), the system will spread that percentage over all previous invoices. So if you bill 50% of retainage held, in AR, the retainage held on each invoice for that contract item will be reduced by 50%. It will not bill 100% of the oldest invoice. To bill by invoice, please see How do I bill retainage by invoice or distribution in Accounts Receivable?
