To do this task
If you haven't already done so, turn on inventory tracking.
Go to the Banking menu and click Write Checks.
Fill out the check, but don't save it yet.
Click the Items tab.
Enter the items to purchase.
If an open purchase order exists for the items, QuickBooks prompts you to
receive against the purchase order as soon as you enter the vendor's name
as the payee.
Click the Site drop-down arrow and select the site where these items will be stored.
Save the check.
