From the Setup menu, choose Balances/Payable Balances to open thePayable Balances window.
Note the amount that appears in the Linked Payables Account Balance field at the bottom half of the Payable Balances window. You should enter historical purchases that, when totaled, equal this amount.
Click the zoom arrow in the scrolling list next to the name of a vendor from whom you’ve made historical purchases. The scrolling list changes to show all the historical purchases that exist for the vendor. (If you’re just starting out, no purchases appear in the scrolling list.)
To enter a historical purchase, click the Add Purchase button. The Historical Purchase window appears.
Enter all information that applies to the historical purchase. When you reach the Total Including Tax, be sure to enter the remaining amount of the purchase, not the original amount. Also select the tax code from the Select from List; the tax portion of the total amount remaining will display. When you’re finished entering the historical purchase, click Record.
Continue entering historical purchases for the vendor until the amount that appears in the Out of Balance Amount field of the Payable Balances window is zero (or as close to zero as you can get it). When you’re finished, click Close.
