My client sent me their file that is in format QBX. The file description says QuickBooks Company Backup File and the size is 427,764kb. When I attempted to convert to QBA I had some errors and I did not have a password. The client said it did not ask her to enter a password. After several attempts, I was able to open the file. I did an entire calendar year of work without realizing when I opened the file it did not say "Accountant's Copy" at the top. All of the work I did was for 2019. There were some adjusting entries, but mostly bank account/credit card transactions and recons.
Is there a way to get my changes into the client's books?
