AMCs maintain a centralized office, which serves as the headquarters for multiple associations. Any overhead costs are shared between the AMC's various clients, increasing each association's resources and capabilities without requiring major capital investment.

Under this shared-resource model specialists are drawn from the personnel pool and are assigned on an as-needed basis, delivering professional expertise for a fraction of what it would cost to hire full-time staff.

There are more than 670 association management companies across the U.S. and beyond. AMCs collectively manage annual budgets exceeding $3.4 billion and represent more than 7,600 clients. These AMCs book nearly 2 million room nights and $1 billion in meetings and conventions services annually.
