Duplicate Vendor Checks Issued By Mistake

(0) ShareShare
ReportReport
Posted on by Vicki Hillary 10

We recently had a case where GP issued duplicate checks to two of our vendors - the same invoice was paid twice with the same check number used.  We do NOT have the allow duplicate check number option turned on for this checkbook, so I am not sure how these duplicate checks were issued.   Fortunately, our vendors notified us of this error and we have taken care of the "extra" payment.  We use Mekorma for check printing.  Looking for tips on how to identify if we have more of these duplicates out there, and also how to prevent it going forward.

Thank you.

    Lisa-thank you for this comment.  I was surprised to find that you can in fact print "duplicate" checks by printing from the Print Preview window for Mekorma and then printing the same check through the normal check printing window for Mekorma.  We have asked them to remove that print button from the preview window as this seems like a security concern.  While we do not think this is the cause of our issue (because not all checks were duplicated in the batch), it is good to know.  We believe our issue is related to a Printer bug associated with a recent windows update.

    A way that you can accidentally end up with printing the same checks multiple times with core GP is to print the checks to the screen and then print from the Screen Output window.  GP doesn't track how many times you print from Screen Output.  (It is a useful method for testing check alignment with new check stock and/or a new check printer.)  Mekorma MICR Preview window probably works the same way.  Implementing tight cash/check procedures is part of critical cash controls.  (Blank check stock should be controlled just like pre-coded check stock.)

    In the US, Implementing SafePay (Positive Pay) is an important way to control what the bank accepts for payment.  (It should prevent the same check from being paid multiple times.)
