Good afternoon, @gerdgoebel.
It's great to see you back in the Community!
To fix sales tax rounding issues between Square and QBDT, there are two options you can choose from:
- Manually adjust each transaction needed in QBDT.
- Create a specific "Rounding Adjustment" item to account for the differences.
However, we recommend speaking with Square's Support to determine if there are any other options that could be more beneficial for you and your business.
Please reach back out and let us know how the chat or call goes with Square. I'll be waiting for your response!
