1. Go to the Banking menu and select Write Checks.
2. Proceed to the Expenses tab and select the Accounts Payable account.
3. Enter all other details of the payment.
4. Click Save and close.

1. Go to the Vendors menu, then select Pay Bills.
2. Select the bill connected to the check.
3. Click Set Credits, then go to the Credits tab.
4. Put a check on the credit or the payment that you made. 
5. Select Done, then select Pay Selected Bills.
