Hi John
With GridView RW, you CAN reverse cleared checks, so long as they still show up in the list of reconciled checks. Just change the setting to Outstanding (and there are a few other fields that need to be reset), and then mark the outstanding check as reversed.
I do it for my clients all of the time.
That's because when you a clear a check in Adagio, it has no accounting ramifications.
If you want, feel free to contact me directly at steve@sschwartzcpa.com, or have your dealer contact me.
Steve
