I am having the same issue. Has there been any fix to this?? It has happened multiple times with one client where a bill that has been paid, weeks before, suddenly shows up in the unpaid bills again. I couple times I actually paid it twice, after panic came over me that it had not gotten paid. Today I went in to a client and noticed bills that were entered and paid a few weeks ago, have just disappeared, the bills and checks. No trace of them in audit reports or anywhere. How can I do business like this?? I am running QB Desktop Accountant 2021 for these particular clients. I use QBOX, and would prefer not to upgrade because I do not want to make them upgrade. It isn't necessary for them. Help!
