Manual upload of transactions can be a valuable alternative, accountant40.
Beforehand, I'd like to ask if you have encountered any specific errors when trying to connect your National Bank of Canada (NBC) bank to QuickBooks Online (QBO)? This way, I can further check if there are known issues or if other users are also having this issue.
Alternatively, you can sign in to your bank's website to check for any alerts or notifications. There may be a maintenance on your bank's end, which is why you're experiencing this problem.
In the meantime, you can still continue manually entering your data into QBO to continue managing your business seamlessly.
Count on me if you need further help with your banking connection. Drop a comment below. I'm just a few clicks away to help you once more, accountant40.
