If you make a payment to a vendor at the time you record the purchase, you can enter the amount paid directly in the Purchases window. Follow these steps:
The Reference, Payment Method, and Cash Account fields appear under the Amount Paid at Purchase field.
In the Payment Method field, select the way that you made the payment, for example, Check.
Tip: You can click the Payment Method link to add, edit, or delete payment methods.
Note: If you have the Hide General Ledger Accounts global option activated, the Cash Account lookup list displays only names of cash accounts currently set up in the chart of accounts. Select the cash account name to apply to this payment. If you want to apply an alternate G/L account (an account that uses an account type other than Cash) for this payment, you must select the Journal button.
