Version 2014 of both Sage 100 and Sage 500 ERP are scheduled to release first quarter of 2014. We recommend that all clients upgrade software routinely to insure you remain on a supported version.
Version 7.3 and earlier of Sage 500 ERP (formerly known as MAS500) are no longer supported. Version 7.4 will roll off support on 9/30/2014.
We are sure you will be pleased with the additional functionality introduced in the past few releases.
