Best payroll software for a 25-employee company in 2026

If you run a 25-person company, payroll software stops being a rounding error and becomes a real line item. At one or two employees, the monthly base fee is what you notice. At 25, the math flips: the per-employee fee does most of the damage, and a few dollars per head compounds into hundreds of dollars a year. That single shift is why "the cheapest base price" is the wrong question at this headcount — and why this ranking is built around total monthly cost, not sticker price.

This guide ranks the two providers PayrollGrade tracks and monetizes — QuickBooks Payroll Premium and RUN Powered by ADP Complete — for a typical 25-employee small business. Everything below is research-based, drawn from published pricing, vendor documentation, and aggregated user reviews. We did not run a live payroll on either platform for this article, so treat the numbers as a budgeting model, not a quote.

Why 25 employees changes the math

Almost every payroll platform in this niche prices the same way: a flat monthly base fee plus a per-employee, per-month fee. The mental shortcut most buyers use — "which base price is lowest?" — works for a solo S-corp owner but breaks at 25 people. Here is the model in one line:

Monthly cost = base fee + (per-employee fee × headcount)

At 25 employees, multiply the per-employee fee by 25. A platform that charges $9 per employee adds $225/month in head-count fees alone — often more than the base fee itself. So a tool with a low base but a high per-employee rate can end up more expensive than a pricier-looking competitor. That is exactly the calculation PayrollGrade's Payroll Cost Estimator automates, ranking each tier by total monthly cost rather than the marketing number.

For a 25-person team, three numbers decide the winner: the per-employee fee, what HR and compliance support is bundled in, and whether tax filing is fully automated. Let's grade the two contenders on exactly that.

The two picks for a 25-person team

1. QuickBooks Payroll Premium — best for cost-conscious teams already in the Intuit ecosystem

Grade: A−

QuickBooks Payroll Premium is the mid-tier of Intuit's three-tier lineup (Core, Premium, Elite). Based on published pricing as of 2026, Premium sits at roughly $85/month base plus about $9 per employee per month — though note Intuit has signaled pricing changes taking effect mid-2026, so confirm the current number on the provider's site before you commit.

For a 25-person team, that works out to an illustrative estimate of about $85 + (25 × $9) = $310/month, or roughly $3,720/year. The per-employee line ($225) dwarfs the base fee — a perfect illustration of why headcount drives the decision.

What you get at the Premium tier, based on Intuit's documentation and user reviews:

• Same-day direct deposit (Core is limited to next-day), which matters when you cut payroll late.
• QuickBooks Time included for time tracking — useful if you have hourly staff.
• Workers' comp administration and HR support resources.
• Automated federal and state payroll tax filing with the provider's accuracy guarantee on the tiers that include it.
• Native, two-way sync with QuickBooks Online accounting — no double entry, no CSV exports.

The strongest case for Premium at 25 employees is when you already run QuickBooks Online. The native integration removes the reconciliation friction that eats hours every pay period, and the per-employee fee stays competitive. The honest weakness: QuickBooks Payroll is reported by users to be self-service first — support exists, but it is not the dedicated, do-it-for-you model some growing teams want.

When to pick it: you want predictable, transparent published pricing, you live in QuickBooks already, and you are comfortable owning the payroll run yourself.

2. RUN Powered by ADP Complete — best for teams that want HR depth and hands-on support

Grade: A−

RUN Powered by ADP Complete (the "Payroll & HR Plus" package) is the step up from ADP's entry-level Essential tier, adding HR tools on top of full-service payroll. The catch buyers hit immediately: ADP is quote-only. It does not publish a base fee or per-employee rate, so any figure online — including ours — is an estimate, not a binding price.

Based on aggregated user reports and third-party reviews, RUN Complete for a 25-person team commonly lands in the rough range of $150–$250+ per month, depending on pay frequency, add-ons, and the deal your rep cuts. ADP also has a quirk that trips up new buyers: historically it can charge per payroll run, so weekly runs cost more than bi-weekly for the same people. Treat that as a model to verify — you have to request pricing to get a real number.

What the Complete package adds over Essential, based on ADP's documentation:

• An HR help desk and HR toolkit — handbook templates, compliance resources, and access to HR professionals, which is where ADP genuinely separates itself from self-service tools.
• Full-service payroll with automated tax filing and ADP's penalty protection on qualifying issues.
• Employee onboarding, background checks, and ZipRecruiter integration for hiring.
• 24/7 support — a real differentiator if you've ever needed payroll help at 9 p.m. before a deadline.
• Strong multi-state compliance muscle, useful if your 25 people are spread across states.

The strongest case for RUN Complete at 25 employees is when payroll alone is no longer the whole job — you're hitting onboarding, benefits questions, and compliance complexity and want a provider's HR team backing you up. The honest weakness is the opacity: you can't comparison-shop the price without a sales conversation, and per-run pricing can make frequent payrolls pricier.

When to pick it: you value 24/7 support and bundled HR muscle over rock-bottom cost, you may be running multi-state, and you're fine getting a custom quote.

How the other names stack up (for reference)

A 25-person ranking wouldn't be honest without naming the competitors buyers ask about. PayrollGrade only places affiliate links on the products we monetize (QuickBooks Payroll and ADP), so the names below are factual reference points, not paid recommendations:

• Gusto — modern and transparently priced, loved for its clean interface and onboarding. Reportedly raised pricing in 2026, so re-check its current per-employee rate before assuming it's the cheap pick at 25 heads.
• Paychex Flex — ADP's closest full-service rival; also largely quote-driven, with comparable HR depth and a similar opacity tradeoff.
• Rippling and Justworks — stronger if you want an all-in-one HR/IT platform or a PEO model, respectively, and usually priced above straightforward payroll at this size.

If your decision is purely payroll cost versus HR support — which it usually is at 25 employees — QuickBooks Payroll Premium and ADP RUN Complete remain the two cleanest answers.

The verdict for a 25-person company

There is no single winner at this headcount — there are two, split by what you actually need:

• Pick QuickBooks Payroll Premium if cost transparency and ecosystem fit matter most. You get a published price you can model in advance, same-day deposit, and a per-employee fee that stays competitive even multiplied by 25 — especially if you already run QuickBooks Online.
• Pick ADP RUN Complete if HR support and compliance depth matter more than the lowest bill. The 24/7 help desk, bundled HR tools, and multi-state strength are worth the quote-only friction once payroll stops being your only people-ops problem.

Frequently Asked Questions

Is QuickBooks Payroll or ADP cheaper for 25 employees?

Based on published pricing as of 2026, QuickBooks Payroll Premium is the more predictable choice on cost — roughly an illustrative $310/month for 25 employees ($85 base plus about $9 per employee), though pricing is changing mid-2026 so confirm on Intuit's site. ADP RUN Complete is quote-only, with user-reported estimates commonly in the $150–$250+ range, but you cannot lock in a real number without requesting a quote. If lowest transparent cost is the goal, QuickBooks usually wins; if bundled HR support is the goal, ADP's higher price buys more.

Why does the per-employee fee matter so much at 25 employees?

Because it scales with headcount while the base fee stays flat. At a $9 per-employee rate, 25 employees adds $225/month in head-count fees alone — often more than the base fee. So the platform with the lowest sticker price isn't necessarily the cheapest in practice. Always multiply the per-employee fee by your headcount and add the base fee to compare total monthly cost, which is exactly what our Payroll Cost Estimator does.

Does QuickBooks Payroll Premium file payroll taxes automatically?

Yes. Based on Intuit's documentation, the Premium tier includes automated federal and state payroll tax filing along with an accuracy guarantee on covered issues. This is general information, not tax advice — verify the current terms and any penalty protection details on the provider's site, since coverage and pricing change.

Is ADP RUN Complete worth it over the cheaper Essential tier for 25 people?

It depends on your HR complexity, not just headcount. RUN Complete adds an HR help desk, HR professional access, onboarding tools, and compliance resources on top of Essential's full-service payroll. At 25 employees — especially multi-state or with frequent hiring — many teams find the HR layer worth the upgrade. If you only need payroll run and tax filing, Essential may be enough. Because ADP is quote-only, request pricing on both to compare your actual numbers.

Can I switch payroll providers mid-year without tax headaches?

You can, but timing matters. Switching at a quarter or year boundary is generally cleanest because it aligns with payroll tax reporting periods and reduces the risk of split W-2s or duplicated filings. Both QuickBooks and ADP support importing year-to-date payroll data during onboarding. This is general information, not tax advice — confirm the migration process and any cutoff dates with the provider and your accountant before you move.
