Hiring your first employee is exciting until tax day shows up on the calendar. Suddenly you’re responsible for withholdings, deposits, W-2s, and state unemployment rules that change by zip code. Spreadsheets and paper checks work for a week. After that, most small business owners want software that runs payroll, files taxes, and keeps them compliant without a full-time bookkeeper.

This guide compares five payroll platforms built for U.S. small businesses, with Gusto as the center of the comparison. We look at pricing structure, who each tool fits, and what to check before you run your first paycheck.

⚠️ This article is for U.S. businesses that pay W-2 employees or 1099 contractors. It is not tax, legal, or HR advice. Rules vary by state and change over time. Confirm current pricing and features on each vendor’s site before you buy.

What small businesses actually need from payroll software

Before you compare logos, list the jobs the software must do:

  1. Calculate pay and withholdings for hourly and salaried staff
  2. File and pay federal, state, and local payroll taxes on time
  3. Produce year-end forms (W-2, 1099) without a last-minute scramble
  4. Direct deposit on a reliable schedule
  5. Employee self-service for pay stubs, tax forms, and address changes
  6. Room to grow into multi-state payroll, benefits, or time tracking

If you’re hiring your first employee in one state, a simple published-price plan is usually enough. If you already have workers in several states, contractors overseas, or device management needs, look further up the stack.

The 5 best payroll options for small business

1. Gusto: Best overall for first-time employers

Gusto is built for small U.S. teams that want payroll, benefits, and basic HR in one place with prices you can see before a sales call. Plans are month-to-month. Every plan includes unlimited payroll runs and tax filings and payments.

How pricing works

There’s also a contractor-only option if you don’t have W-2 employees yet.

Why it fits first-time employers

The setup flow is designed for people who have never run payroll. You can add health benefits, workers’ comp, and retirement later without switching systems. Employee self-service means your team can grab their own stubs and tax documents.

Keep in mind: The lowest tier is single-state. If you hire across state lines, budget for Plus or higher. Add-ons (priority support, same-day pay, some benefits admin) raise the monthly bill.

Best for: U.S. small businesses hiring their first employees and wanting a clear, published plan with room to add benefits.

2. OnPay: Best transparent price with multi-state included

OnPay keeps the bill simple: one base fee plus a per-worker fee, with multi-state payroll and unlimited pay runs included. That makes it easy to compare against Gusto’s Simple plan if you already know you’ll pay people in more than one state.

Why people choose it

Keep in mind: HR extras like richer time tools or benefits administration may be add-ons or thinner than Gusto’s mid and top tiers. Confirm what you need beyond “run payroll and file taxes.”

Best for: Small teams that want a predictable bill and multi-state coverage without jumping to a mid-tier plan.

3. QuickBooks Payroll: Best if you already use QuickBooks

If your books already live in QuickBooks, QuickBooks Payroll is the path of least resistance. Pay runs sync into your accounting, which cuts duplicate data entry and makes tax season less painful.

Pricing shape

Plans usually follow a base fee plus a per-employee fee. Promotional “half-off” prices show up often, so always check both the promo and the list price before you budget for year two.

Keep in mind: The best experience is for businesses already inside the Intuit ecosystem. If you use another accounting tool, Gusto or OnPay may integrate just as well without locking you in.

Best for: Owners who already run QuickBooks Online and want payroll that posts straight to their books.

4. ADP RUN: Best for service-heavy compliance needs

ADP RUN is ADP’s small-business product. It doesn’t publish a simple price list. You get a custom quote based on headcount, pay frequency, package, and add-ons.

Why it still makes the list

ADP has deep payroll and tax experience, package tiers that mix payroll with hiring and HR support, and a large support network. For some industries and multi-state setups, that service layer matters more than a self-serve sticker price.

Keep in mind: Comparing ADP to Gusto or OnPay before a sales call is hard. Ask for a written quote that lists base fees, per-employee fees, off-cycle payroll charges, and contract length.

Best for: Owners who want a guided setup and are fine trading published pricing for a tailored service package.

5. Rippling: Best all-in-one for growing ops

Rippling treats payroll as one module on top of a core employee record that can also power HR, benefits, and IT (devices, apps, access). Pricing is modular: you pay for the core platform plus each product you turn on.

Why growing teams like it

One hire can trigger payroll setup, equipment shipping, and app access from the same profile. Multi-state payroll is built in without a separate “upgrade to unlock states” story on every plan.

Keep in mind: The “from $X per person” headline rarely matches the final invoice once you add payroll, benefits, and IT. Get a quote for the exact modules you’ll use in year one.

Best for: Companies that are past “payroll only” and want one system for people ops and devices.

How to choose payroll software for a small business

  1. Count your states. One state? A basic published plan is fine. Multiple states? Prefer tools that include multi-state at the price you’ll actually pay.
  2. Separate W-2 and 1099 needs. Paying contractors only is cheaper on some platforms. Mixing both is normal; confirm how contractors are billed.
  3. Match your accounting stack. QuickBooks users should demo QuickBooks Payroll. Everyone else should check Gusto, OnPay, or Rippling integrations.
  4. Price the real headcount. Use base + (per-person × employees). Add the cost of time tracking, benefits admin, and priority support if you’ll need them.
  5. Ask about tax filing and year-end forms. Full-service means the vendor calculates, files, and pays. Confirm W-2 and 1099 handling.
  6. Read the contract terms. Month-to-month (Gusto) is easier to leave than a long commitment. Ask about setup fees and data export.
  7. Run a test payroll. Most vendors let you set up before the first live run. Do a dry run with real pay rates and tax settings.

FAQ

What is the cheapest full-service payroll for a small business?

Published entry plans from Gusto and OnPay often land near $50 per month plus about $6 per worker. The “cheapest” option still depends on states, contractors, and add-ons. Always calculate with your real headcount.

Is Gusto good for a one-employee LLC?

Yes for many single-state U.S. LLCs hiring their first W-2 employee. If you only pay yourself as an S corp owner or only use contractors, look at Gusto’s solo / contractor options and compare with a CPA.

Gusto vs ADP vs QuickBooks Payroll — which should I pick?

Pick Gusto for clear pricing and a modern self-serve setup, QuickBooks Payroll if your books are already in QuickBooks, and ADP RUN if you want heavier white-glove service and don’t mind a custom quote.

Do I still need an accountant if I use payroll software?

Usually yes for entity choice, estimated taxes, and year-end planning. Payroll software handles withholdings and filings; it doesn’t replace a bookkeeper or CPA for the rest of your finances.

The bottom line

For most U.S. small businesses hiring their first employees, Gusto is the easiest place to start: published tiers, unlimited payroll runs, and a clear upgrade path into benefits and multi-state payroll. Choose OnPay if you want multi-state on the base plan with a simple bill, QuickBooks Payroll if accounting sync is non-negotiable, ADP RUN if you prefer a service-led quote, and Rippling if payroll is just one piece of a bigger people-and-IT stack.

Pick the tool that matches how many states you operate in, what software you already use, and whether you want a sticker price or a guided sales conversation — then run one test payroll before the first real payday.
