AvaTax for Sage50
AvaTax For Sage50 is a connector between the Avalara AvaTax service and Sage 50 Accounting. The connector works with all flavors of Sage50 and versions 2014 through 2020.
Version 2.0 Uses the newer Avalara .NET REST SDK and has some improved features.
NOTE: Sage will release version 2021 on July 15, 2020. Please do not install this update until we have had a chance to thoroughly check it out with the connector. There is one problem we
know of that can cause problems if you are using Sage 50 in a local network environment: With version 2021 Sage 50 has changed how it determines which computer has control of direct access to the database
and this has resulted in some files being left behind that it no longer uses and this creates some confusion in how to access the database. If you have already installed version 2021 and are getting
errors with the connector, do the following: search all the directories on your computers for files named "~pvsw~.loc" and delete them. These are temporary files that Sage 50 creates that can be left
behind with invalid information, so they can be safely deleted and the next time Sage 50 needs to access the file it will create a new one with the correct information.
