Sage MAS 90, also known as MAS90, is accounting software offered by Sage.[1]
First offered in the mid 1980s by a company called State of the Art, Inc, the Master Accounting Series for the 90's gained significant market share by developing a reseller channel largely made up of Certified Public Accountants (CPAs). These accountants used the product in their own practice, became familiar with it, then subsequently recommended it to their client base. Over time, as technology became more complex and rules on Accountants' independence and objectivity became stricter, nearly all CPAs gravitated away from reselling the software. Now Sage MAS 90 is primarily re-sold by a network of independent software consultants.
Sage MAS 90 primarily targets the wholesale distribution industry, and most of the continued development and enhancement to the software line is centered around the wholesale distribution and warehouse management niche. However, it has many enhancements making it suitable for other industries as well; at present, there are over 20 separate software modules, including some for light manufacturing and e-commerce.
Sage MAS 90 operates in a file server environment. Sage MAS 200 is functionally equivalent, but operates in a client–server environment running under Windows 200x operating systems.
Sage MAS 90 uses Business Objects' Crystal Reports for almost all of its built in and custom reports. Some of the remaining 'legacy' modules, such as Work Order Processing or Job Cost still have 'hard coded' non user editable reports, but users can still create new reports using the included Crystal Reports tool.
In January 2010 Sage released a roadmap guide providing guidance to their future upgrade plans through the year 2012.
In October 2011 Sage released version 4.50 of the MAS 90 (and MAS 200) product line, which included an option to use a Microsoft SQL Server database.
