Network vs Cluster vs Aggregator
What each model actually means, and the questions worth asking before you sign anything.
The three terms overlap and the industry uses them loosely, but they describe different structures. The practical differences that matter to an agency owner are who owns the agency, who holds the carrier appointments, how compensation is shared, and what happens when you want to leave or retire.
How Each One Is Generally Structured
Network or Alliance
Agencies join under a master agreement with a master agency. Members keep full ownership and their own brand. Carrier access, compensation and profit sharing flow through the master agreement, and perpetuation terms are usually written into the contract. SIAA is the largest example.
Cluster
A smaller, often local group of agencies that band together — sometimes informally, sometimes through a jointly owned entity — to share carrier appointments and hit volume commitments. Terms vary widely from one cluster to the next, and so does what happens on exit.
Aggregator
An organisation that aggregates premium across many agencies, typically in exchange for a share of commission or a fee. Scale can be substantial. The key questions are who holds the appointments and whether they travel with you if you leave.
These labels are not standardised. Two organisations calling themselves the same thing can operate very differently — which is why the contract matters more than the label.
Five Questions That Separate Them
Ask these of any organisation you are considering, including MIA.
1. Who owns the agency?
In a network or alliance, you do — membership changes nothing about ownership. In some clusters and aggregator arrangements, joining involves equity in a shared entity. Get this in writing.
2. Who holds the carrier appointments?
Appointments may sit with you, with the master agency, or with a jointly owned company. This determines what you keep if the relationship ends.
3. How is compensation shared?
Look at base commission, overrides, profit sharing and growth bonuses separately — and ask whether any of them carry a minimum volume requirement. At MIA they do not.
4. What happens when you leave or retire?
Ask whether a perpetuation formula is written into the agreement, what happens to your book, and how much notice is required. MIA contractually guarantees perpetuation by a formula in the membership agreement.
5. What support comes with it?
Markets alone are not the whole value. Compare training, help with pricing and placement of large accounts, agency management system discounts, and access to specialty and wholesale markets.
Which model is MIA?
Mississippi Insurance Alliance is a network — the SIAA master agency for Mississippi. Members remain independently owned, keep their own name and staff, and gain access to the network’s carriers and compensation.
Where Mississippi Insurance Alliance Sits
Local relationship, national scale.
MIA operates as a master agency within SIAA, the Strategic Insurance Agency Alliance. SIAA represents more than 5,200 independent strategic agencies and in excess of $18.1 billion in combined premium volume. A Mississippi agency joining MIA deals with people in Jackson while participating in that national scale.
Membership is structured so the agency stays independent: you continue to own and control your agency, keep your local identity, and gain markets, compensation and a contractual perpetuation plan.
