*Note* The functionality of the AvaTax for Quickbooks application and it's link to your Quickbooks Online instance is reliant on Intuit servers. Sometimes, when uninstalling and reinstalling the AvaTax app (or any app in Quickbooks Online) there is a lag between what you see on your screen and what Intuit has processed through their servers. If you do not see the AvaTax buttons on your transactions, please log out of Quickbooks Online and check back in about an hour. This is usually enough time for the Intuit servers to update your instance.
