What's the best payroll software for a small business (Gusto vs ADP vs QuickBooks)?

Best in small business payroll means correct tax filings in every state you pay into, a price that stays predictable as headcount moves, and a short distance between payroll and the systems you already run. Every established provider here calculates withholding, pays by direct deposit, and files federal and state returns, so the separation happens at the edges: how many states your tier covers, whether time tracking and benefits administration are bundled, and who absorbs the cost when a filing goes wrong.

The three named options start from different places

QuickBooks sits closest to your accounting. Intuit renamed its payroll line QuickBooks Workforce in May 2026, so Payroll Core, Premium, and Elite became Workforce Payroll, Workforce Premium, and Workforce Elite [3]. If your general ledger is already in QuickBooks Online, payroll posts to the books without a connector to maintain.

Gusto is built around the employee rather than the bookkeeper, with self-service onboarding and benefits enrollment as the center of the product. Its entry tier runs $49 per month plus $6 per person and covers payroll in a single state [7].

ADP goes deepest on compliance. RUN Powered by ADP comes in four packages, Essential through HR Pro, aimed at businesses with 1 to 49 employees, with higher tiers adding state unemployment insurance management, garnishment services, and more HR support [1].

Price structure decides more than the headline number

Almost every provider charges a monthly base fee plus a per-employee fee, so the cheapest option at five people is frequently not the cheapest at forty. Square's $35 base with a $6 per-person charge [10] costs $65 at five employees and $275 at forty, while QuickBooks Workforce Payroll's $50 base and $7 per-employee fee [4] costs $85 and $330. Model your realistic headcount over the next 18 months before comparing sticker prices, then add state registration fees and the month introductory pricing expires [5][7].

QuickBooks Payroll, now branded QuickBooks Workforce, is the strongest fit if your books already live in QuickBooks Online, because payroll posts straight to the ledger with no integration to keep alive [3]. Since July 1, 2026 the three tiers carry base fees of about $50, $88, and $134 per month, with per-employee fees of $7, $13, and $17 [4]. Intuit held base subscription prices flat in that change and raised only the per-employee rates, with six months of price protection for new subscribers [5].

Feature boundaries between tiers are sharp. Workforce Payroll covers full-service payroll with next-day direct deposit, Premium adds same-day deposit, time tracking, and an HR support center, and Elite adds tax penalty protection up to $25,000 a year, a personal HR advisor, and done-for-you setup by an Intuit expert [6]. Benefits administration is a separate add-on at $5 per active employee per month for companies with 20 or more people [4].

The tier most small businesses actually want is Premium rather than the entry plan, since same-day deposit and time tracking are ordinary needs, and that puts a 15-person company at roughly $283 per month before add-ons [4]. Tax penalty protection, the coverage that matters most on the day a filing goes wrong, only comes with Elite [6].

Gusto is the strongest fit when the employee-facing experience and simple benefits enrollment matter more than accounting proximity. Pricing runs $49 per month plus $6 per person for Simple, $80 plus $12 for Plus, and $180 plus $22 for Premium, with a contractor-only plan at $35 plus $6 per contractor [7]. Simple covers single-state payroll with automatic tax calculations, W-2 and 1099 preparation, direct deposit, and an employee self-service portal [7].

Plus is where most growing companies land, because it adds multi-state payroll and time tracking, and Premium buys dedicated HR professionals, priority support, payroll migration, and custom reports [7]. The Simple base fee moved from $40 to $49 in March 2026, which matters if you are comparing against a quote written last year [7].

The single-state limit on Simple is a hard boundary rather than a soft one, so hiring one person across a state line takes a 10-person company from $109 to $200 per month [7]. State registration charges, benefits broker integration, and year-end correction fees also sit outside the advertised price [7]. One sourcing note: Gusto's own pricing page blocks automated retrieval, so every Gusto figure here comes from an independent review updated June 17, 2026 [7].

ADP RUN is the strongest fit for an employer that expects to pass 50 people, pays across several states, or wants a named compliance contact instead of a help center. The four RUN packages step up from Essential through Enhanced, Complete Payroll and HR+, and HR Pro, adding ZipRecruiter job posting, state unemployment insurance handling, garnishment services, and deeper HR support as you climb [1]. ADP scopes RUN at businesses with 1 to 49 employees and moves larger clients onto Workforce Now [1].

Pricing is quoted rather than published. An independent guide updated January 7, 2026 puts RUN Essential at roughly $79 per month plus $4 per employee and reports no public rates at all for Enhanced, Complete, or HR Pro [2]. What you are quoted varies with business size, pay frequency, how many states you operate in, and which features you take [2].

Pricing opacity is the real cost of this option. You cannot line ADP up against two published-price competitors without a sales conversation, which helps at scale, where the per-employee rate is negotiable, and hurts if you want to decide inside a week [2]. The depth of ADP's tax filing and garnishment handling is why multi-state and regulated employers keep choosing it [1].

A cheaper or more specialized platform wins outright in four situations: a tight budget with plain payroll needs, an existing Square merchant account, device provisioning that belongs with payroll, and a wish for group benefits pricing.

Patriot and OnPay for price-sensitive buyers with straightforward payroll

Patriot Software Full Service Payroll costs $37 per month plus $5 per worker and includes federal, state, local, and year-end tax filings, with a Basic tier at $17 plus $4 for employers who file their own returns [8]. Additional state filings run $12 per month per state, so the savings narrow as your footprint spreads [8]. OnPay charges a flat $49 per month plus $6 per worker, includes payroll in as many states as you need, and adds no implementation fees; its optional HR module costs $15 plus $2 per worker [9].

Square Payroll for merchants already running Square

Square Payroll runs $35 per month plus $6 per person paid, with a contractor-only option at $6 per person and no base fee [10]. For a restaurant or shop already taking payments on Square, hours and tips flow from the point of sale into payroll without a separate integration, and the full-service plan covers multistate payroll and automated tax filings [10]. The advantage shrinks for a business not already on Square hardware.

Rippling when device and app provisioning belong with payroll

Rippling sells a required platform layer plus modules, starting from a $35 monthly base fee with per-employee-per-month charges around $8 for the core platform and comparable amounts for payroll and IT management [11]. What separates it from payroll-first tools is native device management, app provisioning and deprovisioning, and an offboarding action that revokes app access and wipes a laptop alongside the final paycheck [11]. A 50-person company taking HR, US payroll, and IT management lands near $1,235 per month [11], so the case rests on whether Rippling replaces IT tooling you already pay for.

PEOs when you want group benefits pricing and shared liability

A professional employer organization takes payroll, tax administration, benefits administration, workers compensation, and HR support onto its own books under a co-employment arrangement [13]. Justworks lists payroll alone at about $50 per month plus $8 per employee, with PEO plans running roughly $59 to $109 per employee per month depending on tier and headcount [12]. TriNet charges a flat per-employee-per-month administrative fee that stays fixed when someone gets a raise, and says plainly that it does not publish standard list pricing [13]. Benefit premiums and payroll taxes sit outside that fee [13].

Four things reliably change what you pay after signing: hiring outside your home state, introductory pricing expiring, the limits on any tax penalty guarantee, and quote-only rates.

Multi-state hiring is the most common price cliff

Two of the three named platforms change price the moment you hire outside your home state. Gusto's Simple plan is single-state only, so a second state moves you to Plus at $80 plus $12 per person [7], and Patriot adds $12 per month for each extra state [8]. OnPay and Square include multistate payroll at their standard rates [9][10]. Registering with each new state's revenue and unemployment agencies stays your job whichever platform you pick, and those charges are separate from software fees [7].

Introductory pricing hides the real run rate

Half-price offers are standard here. Patriot advertises 30 days free plus 50 percent off for six months [8], and new QuickBooks subscribers get six months of price protection before the July 2026 per-employee rates apply [5]. Compare providers on what month seven costs.

Tax penalty coverage is not standard equipment

QuickBooks reserves tax penalty protection up to $25,000 a year for its Elite tier [6]. Below that, an incorrect filing is yours to resolve even on a plan marketed as full service. Ask any vendor what its guarantee covers and what the dollar limit is before you sign.

Quote-based pricing trades speed for negotiating room

ADP and TriNet both decline to publish standard rates [2][13]. A negotiated number can land below any list price, and it also means you cannot compare three options in a spreadsheet without booking three sales calls.

Switching payroll providers costs time and data accuracy more than money, and the date you pick changes how much of both you spend. The cleanest transitions happen at the start of a calendar quarter, because federal employment tax reporting runs on quarterly Form 941 filings due April 30, July 31, October 31, and January 31 [14]. A quarter boundary lets the outgoing provider close its own return and hands the incoming one a clean starting point.

A January 1 switch is cleaner still. Forms W-2 and the annual Form 940 for FUTA both cover a full calendar year, and W-2s are due to employees and the Social Security Administration by January 31 [14], so one provider then owns the entire year's forms.

Mid-quarter moves are workable and carry more manual work, because year-to-date wage and tax totals for every employee have to load into the new system correctly for Social Security wage bases, withholding, and year-end forms to come out right. Budget for reentering employee records, bank details, deductions, and benefit elections, and consider one parallel cycle if an error would be expensive to unwind.

Several vendors absorb part of that work. Gusto includes payroll migration on its Premium tier [7], OnPay covers account migration with no implementation fees [9], and QuickBooks Workforce Elite includes done-for-you setup by an Intuit expert [6]. Ask what migration covers, since employee record import and year-to-date history import are different jobs.
