Gusto vs Justworks: Payroll Software or PEO?

If you don't know what a PEO is, pick Gusto. Justworks is not payroll software. It's a Professional Employer Organization, which means signing up changes who legally employs your workers. That single difference matters more than every feature comparison you'll read online.

Gusto is payroll software. You buy it, you run payroll through it, your employees work for you. Justworks is a co-employment arrangement. Your employees technically become co-employed by Justworks. Their W-2s show Justworks as the employer of record. Their unemployment claims hit Justworks' state account, not yours. Their workers comp coverage runs through Justworks' master policy. You keep day-to-day management, but the legal and tax infrastructure shifts. Most comparison articles treat these two as interchangeable options on a features spreadsheet. They're not. You're choosing between two fundamentally different models for how your company handles employment.

What Gusto and Justworks actually cost

Gusto's Simple plan costs $49 per month plus $6 per employee but is limited to single-state payroll. Multi-state employers need the Plus plan at $80 per month plus $12 per employee, which adds next-day direct deposit, PTO tracking, and time-off management. The Premium plan requires custom pricing for companies over 25 employees. All plans include tax filing, W-2 preparation, new hire reporting, and basic benefits administration.

Most businesses never price out both models side by side, and the sticker shock only goes one direction.

Justworks Basic costs $59 per employee per month with no base fee. Their Plus plan costs $99 per employee per month and adds medical, dental, and vision benefits through Justworks' large-group plans. For a 20-person company, Gusto Plus runs $240 per month. Justworks Basic runs $1,180 per month. That's nearly five times the cost.

The pricing gap looks brutal until you factor in what Justworks bundles. That $59 per employee includes workers comp coverage, state unemployment insurance administration, compliance monitoring, and HR support. With Gusto, you buy workers comp separately through a broker, manage your own SUI rates, and handle compliance yourself or pay an HR consultant. A 20-person company paying $3,000 per year for workers comp and $2,400 per year for basic HR consulting closes that gap significantly. Whether it closes enough depends on your specific insurance costs and how much HR help you actually need.

Where Gusto wins

You keep control. Your employees work for your company, period. Your EIN is on their W-2s. Your state unemployment account builds its own experience rating. Your workers comp policy reflects your actual claims history, not a pooled risk across hundreds of Justworks clients. For companies that plan to grow past 100 employees, building your own employment infrastructure now avoids a painful unwinding later.

Co-employment is the single most misunderstood employment arrangement in small business.

Gusto's payroll interface is faster and cleaner. Running a standard biweekly payroll takes about five minutes once your employees are set up. The employee self-service portal lets workers update their own direct deposit, download pay stubs, and access tax documents without calling you. Gusto also handles contractor payments and 1099 filing natively, which Justworks does as well but with less flexibility on payment schedules.

Integrations are broader. Gusto connects with most major accounting platforms, time tracking tools, and 401(k) providers. If you use QuickBooks, Xero, or FreshBooks for accounting, Gusto syncs payroll data automatically. Justworks integrations exist but the list is shorter and skewed toward HR tools rather than accounting.

Gusto doesn't charge for off-cycle payroll runs. Need to cut a bonus check or fix a payroll error? No extra fee. This sounds small until you realize providers like ADP charge per run, and even two or three off-cycle runs per quarter add up to hundreds per year.

The tradeoff: you're responsible for everything Gusto doesn't cover. That means shopping for your own workers comp policy, managing your own compliance, and finding your own health insurance broker. Gusto offers benefits administration, but you're still the one selecting plans, negotiating rates, and making coverage decisions.

Where Justworks wins

Health insurance rates. This is the reason most small companies choose a PEO, and it's legitimate. Justworks pools thousands of employees across their client base to negotiate large-group health insurance rates. A 10-person company buying small-group coverage might pay $600 to $800 per employee per month for a decent medical plan. Through Justworks, the same coverage might cost $400 to $550. For a company where the owner is paying a significant chunk of premiums, that savings alone can offset the higher per-employee fee.

Workers comp is included and managed. No shopping for a policy, no annual audits, no surprise premium adjustments. Justworks handles it through their master policy. The tradeoff: you don't control the carrier, the coverage limits, or the claims process. If your industry carries higher risk, like construction, you might get better rates on a standalone policy based on your own clean claims history than you would in Justworks' blended pool.

Compliance support goes deeper than anything Gusto offers. Justworks provides access to HR consultants, handles employment law questions, and manages regulatory filings that would otherwise require outside counsel. For a company without an HR department, this replaces the $150-per-hour employment attorney you'd call twice a year. The IRS maintains a Certified PEO FAQ page that explains the tax implications of co-employment arrangements. When this advantage disappears: companies with an in-house HR generalist already on payroll rarely recoup the Justworks premium through compliance support alone.

State registrations happen automatically. Hire someone in a new state and Justworks handles the SUI registration, workers comp update, and local tax setup. With Gusto, you'd need to register with the state yourself or pay a third-party registration service.

The deal-breaker question

Can you get affordable health insurance without a PEO?

That question decides this comparison more than any feature list ever will.

If you already have a good group health plan or your employees don't need company-sponsored coverage, the PEO model solves a problem you don't have. Pick Gusto, save $30 to $50 per employee per month, and keep full control of your employment relationships. If health insurance is your biggest HR headache and you're a company of 5 to 50 employees getting crushed by small-group premiums, Justworks' large-group rates might genuinely save you money even after the higher per-employee fee. When this math breaks down: companies in states like New York where small-group and large-group health insurance rates are community-rated, eliminating the PEO's purchasing power advantage entirely. Run the actual math. Add up your current monthly spend on health premiums, workers comp, and any HR consulting. If that total exceeds what Justworks Plus would cost, the PEO makes financial sense. If it doesn't, you're paying a convenience premium for bundling services you could buy cheaper separately.

Who should skip both

If you have fewer than five employees and no plans to offer benefits, both of these are more than you need. Running payroll yourself through Patriot Software at $37 plus $5 per employee gives you full-service payroll and tax filing. OnPay at $49 plus $6 per employee includes benefits admin and multi-state payroll at no extra charge, which makes it the better value if you operate in more than one state. Neither locks you into a co-employment arrangement or charges $59 per head. Both still file Form 941 quarterly and handle year-end W-2s. When this recommendation fails: seasonal businesses that hire 20+ workers for three months and need pooled workers comp coverage to avoid standalone policy minimums.

If you have over 100 employees, you've outgrown both. Companies at that size typically have internal HR, established benefits brokers, and the negotiating power to get competitive insurance rates without a PEO. Look at ADP Workforce Now or Paychex Flex for the payroll infrastructure that scales.

What to do next

Pull your last 12 months of spending on health insurance premiums, workers comp premiums, and any HR consulting or legal fees. Add them together. That's your true employment infrastructure cost. Get a Justworks Plus quote for your headcount and compare. If Justworks saves money after accounting for the per-employee fee, the PEO model works for you. If Gusto plus standalone insurance costs less, keep control and save the difference. Start comparing more providers on our payroll provider hub.
