Manually paying an invoice
Manually paying an invoice occurs when you physically write a check for an invoice in the system. For example, a courier delivers a package and you write them a check. You must then manually post the check against the appropriate invoice. Although you can use this method, note that for auditing purposes, the preferred method would be an immediate payment.
If you have the invoice when you manually pay a vendor, you can create the invoice as you record the payment. If you manually pay a vendor, but there is no invoice number, you must enter the transaction as a miscellaneous credit.
