Dear Wayne,
We want to inform you that Avalara will no longer support Connectors for Sage 100 versions 4.30, 4.40 and 4.50. Avalara only provides software updates, fixes and support for versions of Sage 100 which are supported by Sage. Sage no longer supports these older versions and Avalara's support policy follows Sage's.
Your clients can continue to run this software, however Avalara will no longer provide software fixes. You can find all of the 5+ versions of Sage Sales Tax for Sage 100 on the Admin Console for download.
We encourage you to help your clients upgrade to a supported version of Sage 100 so they can benefit.
