Gusto vs Justworks: Payroll Software or PEO?

If you don't know what a PEO is, pick Gusto. Justworks PEO is not payroll software. It's a Professional Employer Organization, which means signing up changes who legally employs your workers. You keep day-to-day management, but the legal and tax infrastructure shifts. 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. You're choosing between two fundamentally different models for how your company handles employment. Justworks also sells Justworks Payroll, which is not a PEO, at $50 per month plus $8 per employee.

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. All plans include tax filing, W-2 preparation, new hire reporting, and basic benefits administration.

Justworks PEO Basic costs $79 per employee per month with no base fee. PEO Plus costs $124 per employee per month and adds medical, dental, and vision benefits through Justworks' large-group plans. For a 20-person company, Gusto Plus runs $320 per month. Justworks PEO Basic runs $1,580 per month. That is nearly five times the cost.

Where Gusto wins

If you use QuickBooks, Xero, or FreshBooks for accounting, Gusto syncs payroll data.

Gusto doesn't charge for off-cycle payroll runs. Need to cut a bonus check or fix a payroll error? No extra fee.

The tradeoff: you're responsible for everything Gusto doesn't cover. Gusto offers benefits administration, but you're still the one selecting plans and making coverage decisions.

Where Justworks wins

Workers comp is included and managed. Justworks handles it through their master policy. The tradeoff: you don't control the carrier, the coverage limits, or the claims process.

Justworks lists dedicated HR consulting as an add-on at $30 per employee per month.

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.

Who should skip a PEO

If you have fewer than five employees and no plans to offer benefits, a PEO is more than you need. Running payroll yourself through Patriot Software at $37 plus $5 per worker gives you full-service payroll and tax filing. OnPay at $49 plus $6 per worker includes benefits admin and multi-state payroll at no extra charge. Neither locks you into a co-employment arrangement or charges $79 per head. Both still file Form 941 quarterly and handle year-end W-2s.

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.

If Gusto plus standalone insurance costs less, keep control and save the difference. Start comparing more providers on the payroll provider hub.
