It's nice to meet you, @tantraww.
To properly assist you with your issue, I'll need to gather some information from you first.
What kind of problems are you having with your transactions? Example: duplicating, missing, or reversed transactions.
Note: If you're missing transactions, I recommend signing out and back into your QuickBooks account. This will allow time for the transactions to load into QuickBooks.
These links below may come in handy.
Once I've received some insight into this matter, I'll be able to get you back to business.
I value you and the success of your business. I'll be waiting for your response.
