Thank you for sharing your detailed concern. I can see how critical it is to ensure the seamless syncing of Tax Code data from QuickBooks to your system to maintain consistency and avoid disruptions. I appreciate the time you've taken to outline the specific challenges you're facing, Karam.

Firstly, the issue arises from a data formatting inconsistency, where QuickBooks is returning the Tax Code List and Tax Code Agency IDs differently. Typically, this occurs due to differences in how data types are handled between the two systems. There may be a mismatch in compatibility regarding the data formats expected by your system compared to what QuickBooks is outputting.

To resolve this, I recommend examining the integration settings within your system to see if there is a way to accept or convert incoming text strings into numeric values. This adjustment could help bridge the format discrepancy. Additionally, you may want to check if an updated integration tools or third-party applications available that align better with the data format used by QuickBooks.

To modify the Tax Code directly in QuickBooks, follow these steps:

1. Go to the Taxes section on the left panel.
2. Click on the Tax Code you wish to update.
3. Make any necessary changes.
