We are often asked about the differences between Sage MAS 90 and MAS 200. Our standard response is that the programs are identical in features and functionality, but MAS 200 has a “stronger back end” to support larger numbers of users and a greater number of transactions. Sometimes, though, this answer isn’t enough and more details are required. Accordingly, see the attached Sage MAS90 vs. Sage MAS 200 Comparison document for a matrix presenting the differences between the two products. In addition, we’ve also attached the Sage White Paper reviewing MAS 90 and MAS 200 technology in general.
