For any number of reasons, you may want to void a check number. You may, for example, find that one of your check forms is damaged and not usable for printing or you may realize that after printing a check for a vendor, the amount of the check is not correct.
Since the check form in the first example will never be used, you may want to void the check number. When you void a check number, no amounts are assigned to the check; instead, VOID appears as the check's amount in the Cash Disbursements Journal.
In the second example, a check transaction using a check number has been recorded, so in addition to voiding the check number, you'll delete or reverse the incorrect check transaction to remove the transaction from your records. (Whether you'll delete or reverse the transaction depends upon whether your company file is changeable or unchangeable. You'll then enter a new, correct check transaction to replace the original transaction.
You can also use the Bank Register window to void a check number. See Spending money using the Bank Register for more information.
Note: Spend Money transactions can be changed
If you have a changeable company file, the check number and other entries in the Spend Money window can be changed. If you printed a check that you no longer want, you'll edit the original check transaction, and you may want to void the check number.
