Can I edit a check after it is created?

Once you create a check, the data on that check and the check itself is time and date stamped. For security reasons, a check may not be edited at any point after creation.

What can I do?

You may void the check and create another one. Voiding an eCheck that was created but not signed does not consume an available check. Voiding a check that was created and signed does consume one of your available checks.
