Ask 10 insurance professionals to define the difference between an aggregator, a cluster, and a network, and you will get 10 different answers. The terms overlap, some organizations use them interchangeably, and the industry has never standardized the definitions.
The good news: the label does not actually matter. What matters is the contract — specifically, five questions that determine whether joining any group is a smart business decision.
The Definitions (As Commonly Used)
Insurance Aggregator
An aggregator pools the business of multiple independent agents or agencies under master carrier contracts. The aggregator negotiates carrier appointments at the group level, giving individual agents access to carriers they could not get independently.
Key characteristics:
- Individual agents write under the aggregator's carrier contracts
- Aggregator takes a commission split (typically 10–30%)
- Agents should (but do not always) own their book of business
- Aggregator may provide technology, training, and compliance support
- Designed for independent agents who want carrier access without volume requirements
Insurance Cluster Group
A cluster group is similar to an aggregator but often implies a tighter, more cooperative structure. The term "cluster" originally referred to independent agencies clustering together to pool premium volume.
Key characteristics:
- Multiple agencies pool volume for carrier access and profit sharing
- May involve shared ownership of some carrier contracts
- Often regional rather than national
- May have more complex exit provisions than pure aggregators
- Sometimes involves shared services (technology, marketing, back office)
In practice, the line between "aggregator" and "cluster" is blurry. Many organizations use both terms for the same model.
Insurance Agency Network
An agency network is the broadest category. Networks range from loose referral groups to formal aggregator-like structures with shared contracts.
Key characteristics:
- Broad term — can mean almost anything
- Some networks are purely for lead sharing and referrals
- Others function exactly like aggregators with shared carrier access
- The term is often used to emphasize agent independence
- Contract terms vary enormously
The 5 Questions That Actually Matter
Forget the label. When evaluating any group — aggregator, cluster, or network — ask these five questions:
1. Do I Own My Book of Business?
This is the most important question. Your book of business is the asset you are building. If the group retains ownership — or if ownership is conditional on meeting production requirements — you are building their asset, not yours.
What to look for in the contract:
- Explicit statement that the agent owns the book
- No lien, buyback clause, or right of first refusal on the book
- Clear language about what happens to the book if you leave
- No minimum tenure requirement before ownership vests
Red flags:
- "You own your book after X years" — ownership should be immediate
- "We have the right of first refusal if you sell" — limits your exit options
- Vague language that does not explicitly address ownership
2. What Is the Commission Split?
Every group takes a percentage of your commissions in exchange for the services they provide. Typical ranges:
- 80/20 (you keep 80%): Competitive — common at aggregators with good support
- 85/15 or 90/10: Better — appropriate for experienced agents with volume
- 70/30: On the lower end — acceptable if training, technology, and support are extensive
- Below 70/30: Hard to justify unless you are brand new with no alternatives
Also ask: Does the split improve over time based on production? Are there performance milestones that increase your percentage?
3. Are There Fees?
Commission splits are the obvious cost — but fees are often where groups make additional margin. Common fees to ask about:
- Startup/onboarding fees
- Monthly membership fees
- Technology platform fees
- E&O surcharges above market rate
- Exit fees or penalties
- Training fees beyond basic onboarding
Some fees are reasonable. Others indicate a group that generates more revenue from fees than from genuinely helping agents grow. Ask for a complete fee schedule before signing anything.
4. What Carrier Access Do You Actually Get?
"Access to 50+ carriers" sounds impressive. What matters is whether those carriers are relevant to your market and your lines of business.
Ask specifically:
- Which personal lines carriers are available in my state?
- Which commercial lines carriers do you have?
- Are carriers available from day one, or does access depend on production thresholds?
- Are any carriers shared with all agents, or do some require individual credentialing?
Carrier access that is geographically irrelevant or locked behind production gates is not really carrier access.
5. What Are the Exit Terms?
What happens if you want to leave? This is the question most agents forget to ask — until they want to leave and discover the answer.
Evaluate:
- Notice period required to terminate
- Non-compete or non-solicitation provisions
- What happens to your carrier appointments on exit — do they transfer?
- What happens to renewal commissions on business you wrote while in the group?
- Exit fees or penalties
The exit terms reveal more about a group's intentions than any marketing material. Groups that make it difficult to leave are groups that profit from keeping you — not from helping you succeed.
Aggregator vs. Cluster vs. Network: Summary
- Aggregator: Formal structure with master carrier contracts, commission splits, and typically clear book ownership. Best for agents who need immediate carrier access.
- Cluster: Similar to aggregator but often with tighter cooperative structure and potentially more complex ownership arrangements. Evaluate contracts carefully.
- Network: Broad term. Can range from a referral group (no shared contracts) to a full aggregator. Ask what "network" means in the specific context.
The bottom line: evaluate any group on the five questions above, not the label they use to describe themselves.
How IPA Compares
IPA is an independent insurance aggregator. Here is where we stand on the five questions:
- Book ownership: Yes — your book is yours from day one. No exceptions.
- Commission split: 80/20 standard, with pathways to improve based on production
- Fees: No signup fees. No monthly fees. No exit fees.
- Carrier access: 50+ personal and commercial lines carriers, available from day one
- Exit terms: Standard notice period. Your book goes with you.
