I have a license version of QB 2016. I have set up the QB from scratch and noticed that when I try to enter "Sales Receipt", although customer name is present (for certain names), it brings up "Customer Job Not Found" dialog. When I click Quick Add, it kicks me back into the same dialog and see that it has added duplicates. I have same issue for some of the item that I use for sales receipt as well.
I have decided to try trial version of QB 2021. However, I get the same issue. Is there anyway for me to send the QB file with instruction to reproduce the issue so that tech support can debug the error?
