ADP vs Gusto in 2026One publishes its prices. The other makes you call.

For almost every company under 100 employees, yes. Gusto Simple is $49 per month plus $6 per person, so a 25-person team pays $199 a month with W-2 filing, unlimited payroll runs and no setup fee included. ADP does not publish a price, but its fiscal 2026 human capital management revenue of $9.12 billion across roughly 26 million US workers implies a blended rate near $29.23 per employee per month. At 25 people that math lands around $731. ADP's average bundles more services than Gusto Simple does, so treat it as a ceiling rather than a quote, but the direction is not ambiguous.

Because its pricing is built around negotiation. ADP serves more than 1.1 million clients ranging from two people to tens of thousands, sells dozens of modules, and generates about $1,123 per Employer Services client per month. A single rate card cannot cover that range without giving away the ceiling to enterprise buyers and scaring off small ones. The standing offer of three months free processing tells you where the flexibility sits: in the sales conversation, not on the website.

Around 250 employees in my experience, and later than most people expect. Below that, Gusto Premium at $180 plus $22 per person covers payroll, benefits administration, time tracking, compliance alerts and an HR resource center for less than a comparable ADP package. The reasons to move are structural rather than financial: multiple legal entities, international payroll, union or certified payroll requirements, a benefits broker relationship ADP already holds, or reporting depth that Gusto has not built.

International payroll in more than 140 countries, deeper multi-entity and multi-EIN handling, hardware time clocks, certified and union payroll, a much larger benefits brokerage operation, and a PEO in ADP TotalSource for companies that want co-employment. ADP also reported client revenue retention of 92.1% in fiscal 2026, which is a real number you can check rather than a marketing claim. If none of those describe your situation, you are paying for reach you will not use.

Neither one is a hiring system. ADP Recruiting Management lists at $3.00 per employee per month with a $2,000 configuration fee, which means a 300-person company pays $10,800 a year for applicant tracking whether it makes four hires or eighty. Gusto covers job posts, offer letters and onboarding checklists but has no pipeline, no structured scorecards and no candidate scoring. Both were built to keep an HR buyer inside one vendor, not to make hiring work.

ADP bills per W-2 and per 1099 plus a year-end processing charge, charges for off-cycle payroll runs, quotes additional state tax registrations separately, and lists implementation as its own line at roughly 10% to 20% of the annual software fee on larger contracts. Gusto includes year-end filing and unlimited payroll runs on every plan, and handles multi-state payroll by tier rather than by per-state fee, starting at Plus. Ask ADP for the complete fee schedule as a document before you compare monthly numbers.

Yes, and Gusto's published page is the strongest lever a small buyer has. Print the plan you would otherwise buy, show the rep the total at your headcount, and ask them to price years one through three rather than year one. ADP grew new business bookings 6% to $2.2 billion in fiscal 2026, so its sales organization is funded to win competitive deals. What it will not usually do is match a published small-business price, because the account is not worth the margin damage.

Less than people fear, and the timing matters more than the tooling. Gusto imports prior wage and tax data and will file for the full year if you move mid-year, but a January 1 switch avoids reconciling two sets of year-to-date figures. The real work is auditing what your ADP contract actually contains before you cancel. Companies routinely find they are paying for time clocks, an HR resource line, and a recruiting module nobody has opened in eighteen months.
