A Microsoft Certified Partner (MCP) is a firm that provides Microsoft-related products or services, or support for such.
They are confirmed by Microsoft to be official, and that they work effectively, and help customers with a range of information technology (IT) projects and specific products and services.
MCPs provide Microsoft services on behalf of Microsoft worldwide, spanning many fields including original equipment manufacturer (OEM), education, software providers, and technical support.
Every MCP has been in business for at least 5 years, has passed several tests, and has proven skills in their particular field.
In return for participating in the program, partners gain support services and tools from Microsoft, often at a significant discount to their retail prices.
