How is the tax information managed between Procore & QuickBooks Online?

The integration transfers Tax Codes from Procore to QuickBooks Online as well as from QuickBooks Online to Procore. 

To be able to sync the Tax Codes, they need to be mapped within Tax Codes Mapping section in your integration.

Requirement: 1-to-1 mapping between the tax codes.

Note: Procore stores only Tax Codes, not the Tax Values.
