I don't recommend deleting memorized reports in QuickBooks because it has been known to cause the file to be corrupted. One alternative is to make a folder called something like “Inactive” or “Old” and move the unwanted memorized reports there instead. Of course, this doesn't always happen as I even have had tons of clients do that without a drag , but it's happened multiple times within the past and you don’t know when it'll happen and you certainly don't want your files getting corrupted.
