When you save a vendor bill, it is posted, so it cannot be deleted. If you need to redo a vendor bill, you can edit it or void it. After you void a vendor bill, you can create a duplicate vendor bill that you can edit.
You cannot undo a void for a vendor bill.
On the Vendors menu, point to Vendor Lists, and then click Bill and Item Receipts.
Right-click a vendor bill, and then click Void.
To confirm, click Yes.
If you select In the future, do not show this warning, you will not be asked for confirmation.
Microsoft Office Accounting 2008 does the following:
Stamps the Vendor Bill form VOID.
Creates a reverse posting with the same financial date, so the vendor bill is financially removed from the ledger, but you have an audit trail.
The VOID stamp also appears in the Bill/Item Receipt List.
