Payroll Services for Small Business: What to Look For

For a small business, a payroll service needs to do three things well: run pay on time, file federal and state taxes automatically, and not cost more than the problem it solves.

Many also collect new-hire paperwork, which can make separate onboarding software unnecessary at this size. Below, six common options are compared, with pricing for 10- and 25-person teams and notes on switching providers mid-year.

The options below are the most commonly used payroll services for small businesses with 1–100 employees. Each is compared on price, main strengths, limitations, and the type of small business it fits best. All pricing is per vendor pricing pages, March 2026.

Gusto — best overall for 1–100 employees

Gusto is the most widely used payroll platform for small US businesses and consistently earns the highest satisfaction ratings among sub-100-employee companies. The Simple plan ($49/month + $6/person/month) covers unlimited payroll runs, automated federal and state tax filing, direct deposit, and contractor payments.

The Plus plan ($80/month + $12/employee/month) adds time tracking, next-day direct deposit, and workforce analytics. Gusto's HR features (offer letters, onboarding checklists, PTO tracking) are included at no extra cost and reduce the need for a separate HR tool at early stage.

Primary limitation: limited support for companies with international employees or complex multi-state requirements.

QuickBooks Payroll — best for existing QuickBooks users

QuickBooks Payroll is the natural choice for any small business already using QuickBooks for accounting — the sync is native and eliminates double-entry.

Now sold as QuickBooks Workforce, its Payroll plan (formerly Core) is $50/month + $7/employee/month, Premium is $88/month + $13/employee/month (adds same-day direct deposit, expert review), and Elite is $134/month + $17/employee/month (adds full-service payroll with a dedicated HR advisor); Intuit raised the per-employee fees on July 1, 2026.

The biggest advantage is accounting integration quality. The limitation: QuickBooks Payroll is less compelling if you're not already in the QuickBooks ecosystem — Gusto offers comparable functionality at similar pricing with better contractor handling.

ADP Run — best for small businesses planning to scale

ADP Run is ADP's small-business product (1–49 employees) that scales into ADP TotalSource (PEO) and ADP Workforce Now (mid-market) as you grow — making it a viable long-term platform rather than one you'll outgrow.

Pricing is quote-based, estimated from about $79/month base plus $4/employee/month on Essential Payroll, with higher packages quoted separately. ADP's tax filing accuracy and liability guarantee is among the strongest in the market. Dedicated account rep access for small business accounts.

Primary limitation: interface is older than Gusto or Rippling, and setup is more involved.

OnPay — best value for under 50 employees

OnPay charges $49/month base plus $6/worker/month, the same pricing as Gusto Simple, — but consistently earns higher support ratings and includes features (multi-state payroll, HR tools, benefits administration integration) that Gusto puts in higher tiers. OnPay handles restaurants, nonprofits, and agricultural payroll particularly well.

It is the most recommended option on HR professional forums for small businesses prioritizing customer support quality and value over brand recognition.

Paychex Flex — best for industries with complex payroll (restaurants, construction, retail)

Paychex is the dominant choice for small businesses in industries with complex payroll requirements: tip credits, piece-rate pay, shift differentials, union agreements, and multi-state seasonal workers.

Paychex no longer lists prices: its last published plan, Flex Essentials, was $39/month base plus $5/employee/month, and all current packages, including full-service plans with a dedicated payroll specialist, are quote-based.

Paychex has the largest small-business dedicated payroll specialist network of any provider — if you anticipate needing a human who knows your account, Paychex is the strongest option.

Square Payroll — best for businesses using Square POS

Square Payroll is purpose-built for restaurants, retail, and service businesses already using Square's point-of-sale and payments ecosystem. $35/month base plus $6/employee/month.

The integration between Square POS and payroll is the primary advantage — hours worked in Square sync directly to payroll without manual entry, reducing errors for hourly worker businesses. Limitation: customer support ratings are lower than Gusto, OnPay, or Paychex. Not recommended for businesses without a Square POS dependency.

Small business payroll pricing comparison — 10 and 25 employees

Gusto, OnPay and QuickBooks prices checked on vendor pricing pages in September 2026. ADP RUN is estimated from buyer reports because its pricing is quote-based, and Paychex no longer lists prices.

How to set up small business payroll — what to expect

Setup time for cloud payroll platforms ranges from 30 minutes (Square Payroll, SurePayroll) to 2–3 hours (ADP Run, Paychex).

The setup process requires: your federal EIN; state employer tax account numbers; employee information (SSN, W-4 withholding, bank accounts for direct deposit); historical YTD payroll data if mid-year (to ensure correct year-end W-2s); and your payroll schedule.

Gusto and OnPay have the most guided setup experiences. ADP and Paychex have more involved onboarding but provide a setup rep to walk you through it.

Switching payroll providers mid-year — what to know

Switching payroll providers mid-year is more complex than starting fresh. You'll need to provide the new provider with year-to-date payroll records so they can generate accurate W-2s at year-end.

Most providers handle this during setup, but you need the data from your previous provider — request it as soon as you decide to switch. The cleanest time to switch is January 1 (new tax year), but mid-year switches are common and manageable.

Give yourself 4–6 weeks of runway for a mid-year switch so there's time to resolve setup issues before the first payroll run.
