We are trying to integrate with Avalara Avatax for QuickBooks Online at avataxforqbo.com and are receiving an error message:
"An Unexpected Error occurred, please contact support,"
We do have a Sales Tax Payable account and have ensured that our credentials are correct and the company code is listed.
If you've ensured that all credentials are correct, that the correct company file is showing, and that there is a valid Sales Tax Payable account in your chart of accounts that is named as such this issue could require intervention from our Development team.
Please Contact us and we'll escalate the issue to our development team for resolution.
