Enter or select a valid general ledger account to which you want to apply the amount due. This only applies if your company uses the accrual method of accounting. If your company uses the cash-basis method, then you can't enter an A/P account. The default for the field will be the last account entered. If no account has been entered, this field will be blank.
If you apply a purchase order to an invoice, this information comes from the purchase order.
Note: If you have the Hide General Ledger Accounts global option activated, Sage 50 will not display the A/P Account field in this window. To modify the A/P account used for this transaction, you must select the Journal button.
