Greetings,

Depending on the MES system, one or more of our Partners may already have an integration available or maybe they have worked with both the Sage 100 and MES System.  Please consider finding a Sage 100 Partner that can work with you to integrate the systems.

Sage 100 does have APIs available through the Business Object Interface.  If you are interested, you may want to tak the Object Interface training course available through Sage University: http://sageu.com/

Thank you,

Kent Mackall
