What Is a Master Agent? Definition, Evolution, and the Modern Alternative for MSPs

A master agent is a channel intermediary that connects agents and sub-agents to multiple telecom and internet carriers under one umbrella. Originating in the 1990s, the model evolved through the 2000s into cloud and VoIP distribution. Today, many MSPs are moving beyond traditional master agents to modern platforms like Viirtue, which offer self-service quoting, instant deployment, usage rating, and automated taxes in a single quote-to-cash workflow.
