It is recommended to use bank sub-accounts for posting incoming and outgoing payments in accounts payable. If you do not use sub-accounts, set up your standard bank accounts in the payment program configuration menu. For more information, see the standard payment program documentation.
It is also recommended to use a different bank sub-account for each payment method. Using such sub-accounts offers some advantages: You can at any time reconcile the balance of the account at your bank with the balance of your corresponding G/L account. The sub-accounts ensure that all incoming and outgoing payments are posted to the G/L bank account until the money is actually debited from/credited to your bank account.
