Gusto vs. Justworks (2026): Payroll Software vs. a PEO

Gusto is the better choice if you want affordable, flexible payroll and benefits you control, while Justworks is a PEO that bundles payroll, benefits, and compliance under a co-employment model — a strong fit for 5–50 person teams that want big-company benefits without an HR department. Both run full-service payroll. The key difference is the model: Gusto is payroll software you operate; Justworks is a professional employer organization that becomes a co-employer of record.

I’ve used Gusto for my agency for about three years. Justworks solves a different problem — let me lay out when each one wins.

Gusto vs. Justworks at a glance

Pricing: per-payroll vs. per-employee

The pricing models are structurally different.

Gusto charges a base plus a small per-employee fee:

• Simple — $49/month + $6 per employee
• Plus — $80/month + $12 per employee
• Premium — $180/month + $22 per employee
• Contractor Only — $35/month (free for the first 6 months) + $6 per contractor

Direct deposit, pay stubs, and tax filing are included. Premiums for any benefits you turn on are separate from the subscription, but the subscription itself is fixed and predictable.

Justworks charges roughly $50–$100 per employee per month (verify current pricing, as PEO rates vary by headcount and tier). That’s substantially more per head than Gusto, but it buys more: as a PEO, Justworks pools your employees with thousands of others to access large-group health plans, and it takes on compliance and HR administration. For a 10-person team, Gusto runs about $109/month total, while Justworks could run $500–$1,000/month — but those dollars cover benefits access and compliance work, not just payroll processing.

Worked example: a 12-person team

Numbers make the trade-off concrete. Picture a 12-employee marketing studio deciding between the two.

On Gusto’s Plus plan (the tier most growing teams land on, because it adds time tracking and next-day deposit), the math is $80 base + 12 × $12 = $224/month, or about $2,688/year, for payroll and benefits administration. Health, dental, and 401(k) premiums are separate and paid to the carriers and providers directly — Gusto doesn’t mark them up.

On Justworks at a mid-range $80 per employee, the same 12-person team is 12 × $80 = $960/month, or $11,520/year — and that figure typically includes access to the PEO’s pooled benefit plans rather than billing them separately. So the comparison isn’t $224 vs. $960 for the same thing. Gusto’s lower number is administration only; Justworks’ higher number bundles the large-group benefits marketplace and compliance support into the per-head fee.

The right question isn’t “which is cheaper” but “what am I buying.” If the studio can get competitive health quotes through Gusto’s broker in its state, Gusto is dramatically cheaper for the same coverage. If it’s in a high-cost insurance market where a 12-person group gets punishing small-group rates, the pooled pricing inside Justworks can close — or reverse — that gap.

The co-employment model explained

This is the conceptual heart of the comparison. With Gusto, you are the sole employer; Gusto is software that runs payroll and files taxes on your behalf. With Justworks, you enter a co-employment relationship: Justworks becomes the employer of record for tax and benefits purposes while you keep day-to-day control of your team.

Co-employment is what unlocks Justworks’ best feature — large-group benefits pricing that a 15-person company couldn’t get on its own — plus offloaded compliance, workers’ comp, and HR support. The trade-off is less control and a higher per-employee cost. It’s a genuinely good model for growing teams that want enterprise-grade benefits without hiring an HR team.

There are practical consequences worth understanding before you commit. Under a PEO, your team is enrolled in the PEO’s master plans, so changing benefits means working within the PEO’s marketplace rather than shopping the open market freely. Some PEOs also have minimum headcounts or onboarding processes that add friction. And leaving a PEO mid-year can be disruptive, because you’re unwinding a co-employment relationship and migrating benefits — it’s not the same as canceling a software subscription. None of this is a knock on Justworks; it’s the nature of the model. It just means the PEO decision carries more switching weight than the payroll-software decision does.

Features: where each one pulls ahead

Gusto leads on:

• Lower total cost for small teams
• Full control as the sole employer
• Transparent, published, all-in pricing
• Strong contractor support, including a contractor-only plan
• Same-day self-serve setup
• No contract, so you can cancel or downgrade without unwinding a co-employment relationship

Justworks leads on:

• Large-group health, dental, and vision via PEO pooling
• Hands-on compliance and HR support
• Reduced administrative and liability burden
• A clean fit for 5–50 person teams scaling benefits
• Multi-state compliance handled inside the PEO as you hire across the country

Who each one is for

It helps to picture the actual business behind each choice.

Gusto fits the bootstrapped agency, the contractor-heavy software shop, the restaurant or retail business watching every dollar of overhead, and any founder who wants to set up payroll this afternoon without a sales call. If your benefits needs are met by the open small-group market — or you mostly pay contractors — Gusto’s control and cost are hard to beat. It’s also the right home base for a company that will grow into a PEO later but isn’t there yet.

Justworks fits the venture-backed startup scaling from 8 to 40 people, the professional-services firm whose recruiting depends on offering benefits that rival much larger employers, and any leadership team that would rather pay a premium than build an HR and compliance function. If you’re hiring across multiple states and losing sleep over payroll-tax registration, labor-law posters, and benefits compliance, the PEO model exists precisely to take that off your plate.

Which should you choose?

Choose Gusto if you:

• Want the lowest-cost path to compliant payroll and benefits
• Prefer to remain the sole employer with full control
• Have mostly contractors or a lean team
• Value transparent, predictable pricing

Choose Justworks if you:

• Have 5–50 employees and want large-company benefits
• Want to offload compliance, workers’ comp, and HR admin
• Are willing to pay more per employee for the PEO model
• Don’t have (and don’t want) a dedicated HR function

Many businesses start on Gusto and move to a PEO like Justworks as benefits and compliance needs grow. There’s no shame in either path. For more, see my Gusto pricing guide and Gusto reviews roundup, or browse the full blog index.

Frequently asked questions

Is Gusto a PEO like Justworks?

No. Gusto is payroll and benefits software where you remain the sole employer. Justworks is a PEO that enters a co-employment relationship and becomes the employer of record for tax and benefits purposes, which unlocks large-group benefits and compliance support.

Is Justworks more expensive than Gusto?

Yes, per employee. Justworks charges roughly $50–$100 per employee per month versus Gusto’s $49/month base + $6 per employee. The higher cost buys large-group benefits pricing and offloaded compliance, not just payroll processing. Compare the right things, though: Justworks’ per-head fee usually bundles benefits access, while Gusto’s fee is administration only, with premiums paid separately to carriers.

When should I switch from Gusto to a PEO?

Consider a PEO like Justworks when you have a growing team (roughly 5–50 employees), want enterprise-grade health benefits, and want to offload compliance and HR admin without hiring an HR team. Until then, Gusto’s lower cost and full control usually win.

Do both run full-service payroll?

Yes. Gusto and Justworks both calculate, file, and pay federal, state, and local payroll taxes, including year-end W-2s and 1099s. The difference is the employment model around the payroll, not the payroll filing itself.

Can I leave Justworks and move to Gusto later?

Yes, but plan for it. Because a PEO is a co-employment relationship, leaving means unwinding that relationship, re-registering as the employer of record for payroll taxes in each state, and migrating your team’s benefits off the PEO’s master plans. It’s more involved than switching payroll software, so most teams time the move to a plan year or quarter boundary. Gusto, by contrast, has no contract, so moving in the other direction is straightforward.

Does Gusto offer multi-state payroll like a PEO?

Yes — Gusto handles payroll and tax filing across multiple states. The difference is that you remain the registered employer in each state and Gusto files on your behalf, whereas a PEO like Justworks is the employer of record and absorbs much of that registration and compliance burden itself. For a lean team in two or three states, Gusto is usually plenty; for rapid multi-state hiring, the PEO model removes more friction.
