Best Payroll Services for Small Business

We started with a pool of 12 payroll services marketed to small businesses and narrowed to 5 based on three filters: the service must handle full tax filing (not just calculations), it must support direct deposit, and it must work for businesses with fewer than 50 employees without requiring an enterprise sales call.

Each finalist was scored on pricing transparency (25%), ease of running a pay cycle (25%), tax compliance features (20%), accounting integrations (15%), and support responsiveness (15%). We weighted pricing and ease of use most heavily because small business owners typically run payroll themselves and cannot absorb surprise fees.

We gathered data from each provider's public documentation, spoke with founders currently using each service, and tested the onboarding flow for each platform. Services with quote-based pricing were evaluated on publicly available plan details and verified user reports.

If you have even one W-2 employee, you need payroll software. Federal and state law requires you to withhold income taxes, Social Security, and Medicare from every paycheck. You also need to file quarterly tax forms (Form 941) and annual W-2s. Doing this manually in spreadsheets is technically possible but creates enormous compliance risk.

Payroll software becomes especially valuable once you cross 3-5 employees. At that point, tracking PTO accruals, managing different pay rates, and filing in multiple tax jurisdictions turns into a part-time job. Automated payroll eliminates that burden for a predictable monthly cost.

You might not need payroll software if you only pay 1099 contractors. In that case, a simple 1099 filing tool or your accounting software's built-in contractor payment feature may be enough. Do not pay for full payroll if you have zero W-2 employees. Contractors who live outside the United States sit outside payroll entirely, and the form you owe there depends on where they did the work, see how to pay foreign contractors.

S corp owners are a case apart. You are your own W-2 employee, so payroll is not optional. There is a second reason, and it costs more when it goes wrong. Your health premium only becomes deductible if the company pays it and payroll reports it on your W-2, in Box 1 but not Boxes 3 and 5. Miss that and the deduction goes, and it is one of the few things that can keep you under the premium tax credit income limit.

Gusto and OnPay are the two strongest options for most small businesses, but they serve slightly different founders. Gusto offers a broader platform that includes benefits administration, HR tools, and an employee self-service portal. OnPay keeps things simpler with a single-tier plan that includes all core payroll features without pushing you toward premium add-ons.

For pricing, both services use a base plus per employee model. Gusto publishes its rates openly, $49 a month plus $6 per person on the Simple plan in September 2026. Gusto's strength is its benefits marketplace, where you can shop for health insurance, 401(k) plans, and commuter benefits directly inside the payroll dashboard. OnPay includes similar functionality but with fewer carrier options.

ADP Run sits in a different category. It is the right choice if you expect rapid growth because it connects to ADP's enterprise products without a migration. However, ADP's pricing is fully quote-based, and multiple users report that costs increase significantly after the initial promotional period. For a 10-person company that plans to stay small, ADP's overhead is hard to justify over Gusto or OnPay.

Square Payroll is a niche pick that makes sense almost exclusively for businesses already embedded in the Square ecosystem. If you use Square for POS, appointments, or invoicing, payroll plugs in without friction. But if you do not use Square for anything else, the limited integrations and fewer HR features make it a weaker standalone payroll tool.

Paychex rounds out the list as the most traditional option. It assigns a dedicated payroll specialist to each account, which is genuinely helpful for businesses with complex multi-state setups or union employees. The trade-off is less pricing transparency and a sales-driven onboarding process that some founders find frustrating.

Gusto and QuickBooks Payroll, what each one really costs

Gusto and QuickBooks charge almost the same for payroll by itself. Gusto's Simple plan is $49 a month plus $6 per person. QuickBooks Workforce Payroll is $50 a month plus $7 per person. The real gap sits somewhere else, in whether you already pay for QuickBooks accounting.

If you already keep your books in QuickBooks, adding payroll costs about what moving to Gusto costs. At five employees the difference is $6 a month.

If you do not use QuickBooks, the picture changes. Intuit's buying page asks you to pick a payroll plan first, then add an accounting plan. The cheapest pairing it lists is $88 a month plus $7 per person. At five employees that works out to $123 a month against Gusto's $79, so $528 more over a year. Neither company's own comparison page leads with this, because both are answering a features question instead.

One difference runs the other way. QuickBooks includes direct deposit the next day at its entry price. Gusto charges $15 a month plus $3 per person to add next day pay to Simple, and includes it on Plus and Premium. If paying your team quickly matters, add that cost to the Gusto side before you compare.

Two notes on the numbers above. Intuit renamed this product line QuickBooks Workforce, so payroll now comes bundled with every Workforce plan rather than sold as a bolt-on. And the prices here are list prices. Intuit advertises half off for three months, which is worth taking, but it ends.

Watch out for payroll services that advertise a low base price but charge steep per-employee fees that multiply as you hire. A service quoting $20/month base plus $15/employee costs you $170/month at just 10 employees. Always calculate your total cost at your expected headcount for the next 12 months, not just today's team size.

Avoid any provider that requires a long-term contract before you have run at least one full payroll cycle. Some legacy providers lock you into 12 or 24-month agreements with early termination fees of $500 or more. Also be cautious of services that charge extra for basic tax filing, W-2 distribution, or direct deposit. These should be included in any modern payroll product, not sold as add-ons.

If Gusto and OnPay do not fit, the next best option depends on your specific situation. Square Payroll is the obvious choice for any business running Square POS. You get time tracking, tip management, and payroll in one system. For restaurants, retail shops, and service businesses already on Square, switching to a separate payroll provider creates unnecessary data entry.

ADP Run makes sense if you are a funded startup planning to scale to 50+ employees within 18 months. Starting on ADP now means you will not face a painful migration later. The initial promotional pricing can make it competitive with Gusto for the first few months, but confirm in writing what your rate will be after the promo ends.

Paychex is worth considering if you value human support over software polish. Having a named specialist who knows your account is valuable when dealing with a state tax notice or a complex garnishment. Just be prepared for a longer onboarding process and less intuitive self-service tools compared to Gusto or OnPay.

Payroll is only half of the back-office equation. If you also need automated bookkeeping and expense categorization, several AI-powered tools now handle that with minimal manual effort. See our roundup of AI bookkeeping tools for small business for options that pair well with whichever payroll provider you choose.

Should a Small Business Use a PEO Instead of Payroll Software

A PEO costs far more than payroll software, because it does far more. Justworks, one PEO that posts its prices, charges $79 per employee a month. PEO is short for professional employer organization. It becomes a co-employer of your staff. You still hire people, set their pay and run their day. The PEO takes over payroll taxes, workers' comp and benefits through its own accounts and plans.

Both prices are the lowest plans each company lists, billed monthly. Neither includes the payroll taxes or any insurance premiums. For five people, Gusto's whole bill equals what Justworks charges for one. Over a year the gap is $3,792.

Read the tax row twice. When you use an outside payroll company, the IRS says you stay responsible for the tax you withhold and for both shares of Social Security and Medicare tax. A certified PEO, called a CPEO, is the exception. For staff at your worksite, the IRS generally makes the CPEO alone liable for paying those taxes. The IRS posts its list of certified PEOs. A CPEO contract must show the PEO's exact name and employer number, so check the contract against the list before you sign.

A PEO earns its fee when your team needs benefits you cannot buy well alone. On Justworks, that is the PEO Plus plan at $124 per employee a month, which adds medical, dental and vision benefits administration. If you have five employees and no plan to offer health cover, $3,792 a year buys you little. Gusto or OnPay above will do the payroll job. If you do sign with a PEO, ask two things first. Whose state unemployment account will your wages go under? And what happens to your health plan and workers' comp cover if you leave?
