The short version: these are three different relationships, not three competing products. Gusto is an HR platform — software plus service, with your company as the sole employer. TriNet is a PEO — a co-employer whose master health plan your employees join. An independent broker is a specialist who works for you, places your coverage anywhere in the carrier market, and pairs with whatever payroll setup you already have. Most comparison shopping goes wrong by treating them as interchangeable.
If you’re evaluating how to handle payroll, HR, and health benefits together, these three names come up constantly — usually in the same breath, as if they were direct competitors. They’re not. Each one answers the question “who takes care of my people?” with a different structure, and the structure determines what you pay, what you control, and what happens when you want to change.
The three models in one table
| Gusto (HR platform) | TriNet (PEO) | Independent broker | |
|---|---|---|---|
| What it is | Software + service vendor | Co-employer | Specialist advisor for benefits |
| Legal employer | You | Shared (co-employment) | You |
| Payroll taxes | Your EIN | TriNet’s EIN | Not their domain — pairs with any payroll |
| Health benefits | Your own small-group policy, from Gusto’s carrier menu | TriNet’s master plan, pooled across clients | Full carrier market, placed in your company’s name |
| Plan structures available | Standard fully-insured options | The PEO’s plan menu | Fully-insured, level-funded, self-funded, ICHRA |
| Claims data access | Limited | Limited — the plan is the PEO’s, not yours | Yours to demand, especially under level/self-funding |
| Workers’ comp | You source it | Typically included under the PEO | You source it (broker can coordinate) |
| Who they answer to | Their platform economics | Their pool economics | You — and you should ask exactly how they’re paid |
| Switching away | Change vendors | An unwind: new EIN registration, replacement benefits | Change brokers; your policies stay |
What each one actually is
Gusto is payroll and HR software with a benefits offering attached. It is not a PEO — your company stays the sole legal employer, and benefits placed through Gusto are your own group policy, chosen from Gusto’s carrier partnerships and serviced by Gusto’s in-house benefits team.
TriNet is a professional employer organization. Through co-employment, TriNet becomes the employer of record for payroll and benefits purposes. The benefits upside is access to large-group-style plans pooled across TriNet’s client base; the trade is that the plan belongs to TriNet, not to you — carriers, plan menu, and renewal pricing are decisions you receive, not decisions you make.
An independent broker doesn’t process payroll and doesn’t co-employ anyone. A broker’s job is to design, place, and manage your health benefits: shopping the full carrier market, presenting structures a platform menu won’t (level-funded and self-funded plans that return surplus and expose claims data), and advocating at renewal. A broker pairs with Gusto, with in-house payroll, or with anything else.
Where the comparison actually gets decided
Most teams start this comparison thinking about payroll features. It usually ends up being decided by benefits, for one reason: as your team grows, health benefits become a far larger line item than any software subscription. The differences that matter are:
Who owns the plan. With Gusto or a broker, the health plan is yours — it follows your company. With TriNet, coverage exists through the co-employment relationship, which is part of why leaving a PEO takes planning.
How wide the market is. A platform sells from its menu. A PEO sells its pool. A broker shops the market — and is the only one of the three that will routinely present alternative funding structures that give you claims data and surplus refunds.
Whose incentives point where. Platforms monetize bundling. PEOs monetize the pool. Brokers are paid by commission or fee — which is exactly why you should ask any broker how they’re compensated. Transparent compensation is the difference between an advisor and another sales channel.
The question isn’t “which of these three is best?” It’s “which relationship do I want for payroll, and which do I want for benefits?” Those are two decisions, and nothing forces them to have the same answer.
When each one wins
Gusto’s bundled benefits fit when you’re very small, your needs are standard, and administrative simplicity is worth more to you than market access.
TriNet (or another PEO) fits when you’re small, want HR genuinely taken off your plate, value bundled workers’ comp, and accept the pool’s pricing in exchange — with eyes open about the costs the bundle can hide.
An independent broker fits when benefits spend is big enough to manage deliberately — for many companies that’s somewhere past ten to fifteen employees — or when you want plan structures, carrier choice, and claims data that neither a platform menu nor a PEO pool will give you. The full PEO vs. independent broker breakdown goes deeper on this fork.
The hybrid — platform for payroll, broker for benefits — fits most growing companies best. It’s not a compromise; it’s specialization. Payroll is a software problem. Benefits is a market-access and advocacy problem.
How to run the comparison for your company
- Price all three configurations, not two: TriNet’s full bundle; Gusto with Gusto benefits; Gusto (or your current payroll) with broker-placed benefits.
- Compare totals, not line items. PEO pricing bundles administration into one number; unbundled setups show their parts. Sum each configuration completely.
- Ask each option the same three questions. What plan structures can you offer me? What claims data will I see? Exactly how are you compensated?
- Weigh the exit. Ask what leaving looks like in year three. The answers differ more than the sales decks do.
What this means for your business
Gusto, TriNet, and an independent broker aren’t three prices for the same product — they’re three structures with different owners, different markets, and different incentives. Platforms are excellent at payroll. PEOs are a real option for the smallest teams that want everything handled. But once benefits become your second-largest expense after wages, the flexibility and advocacy of a specialist working for you — not for a menu or a pool — is usually where the economics land.
