Microsoft Dynamics is a line of enterprise resource planning (ERP) and customer relationship management (CRM) software applications. Microsoft markets Dynamics applications through a network of reselling partners who provide specialized services. Very few installations take place without the aid of third-party resellers.

The Microsoft Dynamics focus-industries are retail, services, manufacturing, financial services, and the public sector. Microsoft Dynamics offers services for small, medium, and large businesses.
