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 2021.
Version 2.0 Uses the newer Avalara .NET REST SDK and has some improved features.
NOTE: Sage50 2021 has an issue that can cause problems if you are using Sage 50 in a local network environment: Version 2021 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, which creates some confusion in how to access the database and may cause the Avatax connector to run very slowly or not at all.. If you install version 2021 and are getting
errors with the connector, do the following: stop Sage 50 on all computers, search all the directories on each computers for files named "~pvsw~.loc" and delete them. These are text files that Sage 50 creates that can be left
behind with invalid information, so they can be safely deleted. Next, start Sage 50 on the computer wher the Sage 50 database resides, then restart Sage 50 on the other computers. This will create new versions of the ~pvsw~.loc files with the correct information.
