Hello there, @PlayaRoundGolf.
I'd like to ensure that you'll be able to import your transactions successfully using the IIF importer from AaaTeX.
QuickBooks with various third-party applications to make the system work the way your business needs. To help you with importing transactions, I recommend contacting the AaaTeX Customer Care Team. They'll be able to guide you on how their product works and walk you through with the procedure.
In addition, here are links that you can visit about importing bank transactions and fixing upload errors in QBO, in case you need it in the future:
I got your back if you have any other questions. I'm always here to help. Wishing you all the best and take care.
