The Sage MAS 90 Business Framework Object Interface provides developers and business partners with access to business objects within Sage MAS 90 through a common and secure interface while offering them a development language of choice such as Visual Basic, C++, or Delphi. The Object Interface can be used for data retrieval and updates as well as complex transaction inserts. This ultimately provides developers with the ability to perform tight integrations with Sage MAS 90 by leveraging the data validation routines within the Sage MAS 90 business objects without modifying or reengineering the underlying source code of the application.

Another aspect of the Object Interface is the ability to control the user interface associated with the business object. This can be extremely useful when user intervention is required by the user as part of the communication between the custom program and the Sage MAS 90 business object. Portions of the user interface can be rendered to the user such as a dialog box or inquiry form.
