What's the difference between payroll software and a PEO?

Payroll software (like Gusto or OnPay) is a tool you run yourself: you stay the employer of record and the software handles calculations, filings, and payments. A PEO (like Justworks or TriNet) co-employs your staff, pooling them with other clients to offer richer benefits and take on more compliance work, usually at a higher per-employee cost and with less direct control.

Do these tools file my payroll taxes for me?

Full-service options handle federal, state, and often local tax calculations, filings, and payments on your behalf, which is the main reason to buy rather than do it manually. Always confirm coverage for every state and locality where you have employees, since some lower-cost or self-service tiers leave certain filings to you.

Which is best if I employ people or contractors outside the US?

For international teams, look at platforms built for global payroll and contractor compliance such as Deel, Remote, or Papaya Global. Most US-centric payroll tools handle US W-2 employees well but aren't designed to pay or stay compliant with workers in other countries.

I run an hourly or shift-based business. What should I prioritize?

Prioritize tight integration between scheduling, time tracking, and payroll so hours flow through without manual re-entry. Tools like Homebase, When I Work, and Deputy focus on hourly teams; some pair scheduling with payroll directly, while others feed hours into a separate payroll provider.

How is HR and payroll software usually priced?

The common model is a monthly base fee plus a per-employee-per-month charge, and add-ons for benefits administration, time tracking, or advanced HR can raise the total. PEOs typically cost more per employee because they bundle benefits and compliance services, so compare all-in costs for your specific headcount rather than headline rates.

Best HR & Payroll Software (2026)

HR and payroll software handles the operational backbone of employing people: running payroll accurately, filing payroll taxes, tracking time and time off, managing benefits, and keeping employee records and compliance documents in one place. As your headcount grows past a handful of people, spreadsheets and manual bank transfers stop scaling, and a single missed tax filing or misclassified worker can be costly.

For most small and mid-sized businesses, the right tool depends less on feature checklists and more on your shape: are you paying salaried W-2 staff, hourly shift workers, or international contractors? Do you want a light payroll engine or a full people platform that also handles onboarding, performance, and benefits? A PEO that co-employs your team and bundles benefits is a very different model from a self-serve payroll app you run yourself.

Start by mapping your workforce (employee types, states, and countries), decide whether you want payroll-only or a broader HRIS, and confirm the tool actually files taxes in the jurisdictions where you operate. Then weigh integrations with your accounting stack, the quality of support, and how much administrative work stays on your plate.

Our top HR & Payroll picks

Who each pick is actually for

Two facts below, both arithmetic rather than opinion, taken from the review scores in our catalog. Neither is a recommendation, and a high score from a small group of users is a different claim from a high score at scale, so the sample size is shown alongside every figure.

Most reviewed

Deel

4.8 across 14,287 reviews

The largest sample in our entire catalog, and it is measuring one specific problem rather than payroll in general. Deel exists to hire and pay people in countries where you have no legal entity, across more than 150 of them, which is why it costs $49 a person and why it is rated so warmly: the alternative its buyers were weighing was incorporating a foreign subsidiary. If everyone on your payroll is in one country, almost all of what you would be paying for is compliance you will never touch.

Highest rated

Rippling

4.9 across 4,846 reviews

The best-liked tool in the category, and the one attempting the most: HR, payroll, benefits, devices, apps, and company spend on a single employee record. The consolidation is real and so is the bill. The $8 figure is the published entry rate for the Core HR seat only; payroll and the IT and finance modules are quote-only and stack on top, which is why we file it as premium. It is also worth reading against the older end of the market, where Paycor sits at 3.9 and TriNet at 4.0 on samples over a thousand, because in payroll the person who signs the contract is rarely the person who has to use it.

None of that decides it for you

You do not need an HR system, you need to know who is off next week: Timetastic - Leave requests, allowance tracking, and a shared wall chart for $1.50 a person, and deliberately nothing else. Every HR suite here includes this feature, and reaching it means paying for eleven modules you did not want.
Everyone is hourly and the roster changes every week: Homebase - Scheduling, a time clock, and team messaging on a free tier, with payroll running off the same approved timesheets so the hours are not retyped. Deputy at $5 and When I Work at $2.50 schedule just as well, but you would still be buying payroll somewhere else.
You want payroll and nothing else, as cheaply as possible: Patriot Payroll - US payroll with tax filing and direct deposit from $17, and 4.8 across 3,700 reviews, which is a big enough sample to trust at that price point. It makes no attempt to be an HRIS, so if you need records, onboarding, and reviews too, this is the wrong end of the market.
You just hired someone in another state: OnPay - Flat-rate full-service payroll that registers and files across all US states, so a remote hire somewhere you have never had an employee is a form rather than a project. Flat pricing also means multi-state filing is not the thing they upsell you on once you are committed.
Hiring is the part that is actually broken: Zoho Recruit - A real applicant tracking system: resume parsing, configurable pipelines, a branded careers site, and job board posting, priced per recruiter rather than per employee and with a free tier. HR platforms bolt a hiring tab onto the employee record; here the pipeline is the product.
You are competing for people on benefits, not salary: Justworks - A professional employer organization: it co-employs your staff so a fifteen-person company can offer large-group health plans and hand compliance to someone else, at $50 a person. The other PEO in this category, TriNet, sits at 4.0 across 1,250 reviews, so do not assume the co-employment model is what makes the difference here.
Records, onboarding, and reviews matter more than the pay run: BambooHR - An HRIS first: one employee record, onboarding workflows, time off, and performance reviews from $10, with payroll as an option rather than the point. Buying a payroll engine and hoping the HR side is adequate is the same mistake in the opposite direction.

What to look for

Full-service payroll that automatically calculates, files, and pays federal, state, and local payroll taxes, not just cuts checks
Coverage that matches your workforce: hourly vs. salaried, multi-state, and international contractors or employees if relevant
Whether it's a payroll-only tool, a broader HRIS, or a PEO co-employment model, since each carries different cost and control trade-offs
Employee self-service and clean onboarding so new hires can complete paperwork, view pay stubs, and manage details without HR doing everything
Integrations with your accounting software, time tracking, and benefits providers to avoid double data entry
Transparent pricing (base fee plus per-employee) and responsive support, especially around tax deadlines and year-end filings
