Hi Rosebud1,
Currently, reverting a purchase order isn't possible. You'll have to delete and create them if you want to correct the error.
Here's how:
- Click Vendors on the upper menu,then select Vendor Center.
- Select the purchase order.
- Click Delete on the upper menu beside the Save icon.
- Click OK.
Once done, you can recreate a new purchase order. Then , create a bill and pay them in QuickBooks. Please visit this article: Pay Bill in QuickBooks Desktop.
You can touch base with us if you need anything else.
