Difference Between Voiding and Erasing Checks
NOTE: If you are using the U.S. version, the word check will be displayed. If you are using another countries version of the software, the word cheque will be displayed.
When you void a check that is changeable it will remove the dollar value of that check and will show up as VOID in the bank register.
When you void an unchangeable transaction it will create a reversal of the original transaction. Both transactions will show up as VOID when you drill into them.
For more information about voiding check transactions please see this article.
When you delete a check it removes the cheque entirely from the system. You will no longer see that check transaction anywhere in the system.
