You'll encounter a "Failed when handling conflicts" error when your CSV/QBJ file has account numbers, account names, and account types that differ from the information in QuickBooks.
Let's ensure all names, numbers, and types are the same before importing the copy. This way, you'll encounter no error messages.
You can get back to this thread after checking. We're available 24/7 to help you. Keep safe!
