An merchandise management system or merchandise management software, in short MMS, is a company solution for the illustration of the flow of goods and business processes of a company. The definition is mainly used in connection with software for disposition and logistics. The transition between merchandise management system and ERP system is not clearly defined. The differentiation is usually based on the scope of functions. If, for example, functions or modules are integrated in the area of controlling and materials management, one speaks of an ERP rather than an MMS.
In the Microsoft Dynamics 365 Business Central / NAV business solution, all business functions are combined in an integrated system. The Navision ERP solution thus goes beyond the pure functions of a merchandise management system or merchandise management software.
