Gusto vs ADP 2026 Comparison

Gusto and ADP RUN are the two payroll platforms small businesses shortlist most often in 2026. Both file federal, state, and local taxes in all 50 states, both run W 2 and 1099 payroll in the same batch, and both carry liability for errors caused by their own automation. The honest differences live in pricing transparency, contract length, and what happens when you need real HR help.

We researched both as of April 17, 2026. Gusto publishes every price on its plans page, starts at $49 per month plus $6 per person on Simple, and bills month to month on every tier. ADP RUN does not publish prices, routes every buyer through a sales quote, and signs most small businesses to a 36 month contract with an early termination fee. ADP is running a six months free promo on its small business landing page at capture date, which bends year one cost but not the contract shape. Gusto's Trustpilot score is 2.5 from 2,364 reviews. ADP RUN's is 1.5 from 2,921 reviews.

If you have not picked a payroll provider yet, start with Gusto and do not overthink it. Published pricing means you can forecast the line item before you sign anything. Month to month billing means a bad quarter does not lock you in. First payroll typically runs in under 10 minutes once the roster is imported. ADP RUN Essential is fine, but every price is a sales quote and the standard contract is 36 months with an early termination fee.

If you only pay contractors today, Gusto Contractor Only at $35 per month plus $6 per contractor is the cheapest honest option on this page. ADP does not sell a 1099 only plan. Revisit ADP the moment you cross 50 employees or decide you need a named HR Business Advisor.

At 10 to 25 employees the decision starts to matter. Gusto Plus at $80 per month plus $12 per person covers multi state payroll with native time tracking bundled, no add on invoice. ADP RUN Enhanced covers the same functional ground but through a sales quote and a 36 month contract. The 6 months free promo on ADP''s landing page meaningfully lowers year one cash cost, but it does not change the contract shape.

Budget realistically. A 10 person Gusto Plus deployment lands around $7,200 over three years, time tracking included. The same team on ADP RUN Enhanced with time tracking lands around $9,666 net over three years, factoring in the 6 months free promo. Gusto pulls ahead over the full three year window. ADP is closer if the team expects to scale past 50 employees inside that window and wants a single vendor for the jump.

At 50 plus employees the economics shift. Gusto''s own user reports flag reliability issues past 50 employees, especially for multi state teams with complex benefits. ADP RUN is the natural on ramp to ADP Workforce Now, which covers payroll, HR, benefits, time, and talent for 50 to 999 employees on the same underlying platform. That upgrade path is the single biggest ADP advantage at this size.

Common pattern at this stage is ADP for payroll plus HR, with a named HR Business Advisor on HR Pro, a Workforce Now upgrade mapped in the contract for the year the headcount will cross 50, and a dedicated payroll administrator on the team. Budget for the 36 month commitment, price the early termination fee into any exit planning, and factor ADP''s history of quote inflation at renewal into three year modeling.

We compared Gusto and ADP RUN on pricing, contract terms, payroll features, HR support, integrations, mobile experience, reputation, and recent news. Prices were captured April 17, 2026 from each vendor''s public pricing surface. Gusto publishes every price, ADP RUN does not, so all ADP price points are third party estimates clearly labeled in the matrix and total cost of ownership. Pros and cons are drawn from the production copy on our /reviews/adp-run and /reviews/gusto pages, which are sourced to vendor docs, Trustpilot counts, Reddit sentiment, and independent review sites. Where a claim could not be verified against a primary source, we flagged it in the research file rather than assert it here.
