Selected invoice date must be less than or equal to the check date
Also described as. "How to print a check with a date that is earlier than the invoice date?"
The message, "Selected invoice date must be less than or equal to the check date," means you cannot pay a bill with a check which has a date that falls before the invoice date. You will need to date the check on or after the date of the invoice. Our software was intentionally designed to disallow check dates to fall before invoice dates per the request of our customers.
