Gusto vs ADP RUN for Small Businesses With 5 to 25 Employees: Pricing, Features, and Best Fit

The short answer is simple: Gusto is usually the better fit if you want transparent pricing, a faster buying decision, and an easy payroll-plus-benefits stack. ADP RUN is usually the better fit if you want deeper service layers, stronger live support coverage, or more help as payroll complexity grows.

Gusto vs ADP RUN at a glance

Pricing and value for a 5 to 25 employee team

Gusto is easier to evaluate upfront because it publishes standard pricing. As reviewed in March 2026, Gusto Simple is $49 per month plus $6 per person, Plus is $80 plus $12 per person, and Premium is $180 plus $22 per person. For a 10-person team, that works out to about $109, $200, or $400 per month before add-ons. For 25 employees, it becomes about $199, $380, or $730 per month.

ADP RUN takes a different approach. Instead of posting one public monthly price, it offers four packages: Essential Payroll, Enhanced Payroll, Complete Payroll & HR Plus, and HR Pro Payroll & HR. Your quote can vary based on headcount, payroll frequency, tax setup, and add-ons. ADP also notes that payroll fees may increase with frequency, which matters if you run lots of off-cycle payrolls.

• Choose Gusto if you want predictable budgeting and easy plan comparison before talking to sales.
• Choose ADP RUN if you are willing to get a quote in exchange for a more service-heavy setup.
• For most owners comparing options quickly, Gusto has the easier buying experience.

Payroll, taxes, and day-to-day administration

Both platforms cover the essentials that matter most to a 5 to 25 employee company: payroll processing, tax calculations, tax filing support, direct deposit, employee self-service, and room to add HR tools over time. Neither is a weak payroll product.

Gusto stands out for simplicity. Its public plan structure makes it clear what changes as you move up. Simple is aimed at single-state payroll, while Plus adds multi-state payroll, next-day pay, time tracking, and basic PTO policies. Gusto also includes unlimited payroll runs on standard plans, which is useful if you sometimes need corrections, bonuses, or one-off payments without worrying about run-based charges.

ADP RUN stands out for operational control and compliance support. ADP emphasizes automatic tax deductions and filings, recurring payroll through RUN & DONE, AI-enabled error flagging, a mobile app, and integrations with accounting, POS, and other business systems. If your payroll risk feels less like convenience and more like avoiding mistakes, ADP RUN is very compelling.

HR tools, support, and scalability

For a growing small business, payroll software often becomes an HR platform by accident. That is where the two products begin to separate more clearly.

Gusto is a clean all-in-one option for businesses that want payroll, benefits administration, time tracking, and basic HR resources in one modern interface. Premium adds a dedicated service advisor, access to certified HR experts, advanced reporting, and priority support. That is a strong path for businesses growing steadily without wanting a heavy vendor process.

ADP RUN offers more layered service packages. Enhanced adds items such as ZipRecruiter access, state unemployment insurance support, and garnishment payment service. Complete adds basic HR support. HR Pro adds enhanced HR support, training, legal support, and employee perks. For businesses that expect more hiring, policy questions, or compliance complexity, those extra layers can justify the more consultative buying model.

• Gusto support is available Monday through Friday, 6am to 6pm MST by phone, email, and chat.
• ADP RUN offers live payroll support 24/7/365, with chat and virtual assistant options as well.
• If nights, weekends, or urgent payroll issues are a real concern, ADP RUN has the support advantage.

Which one is better for most 5 to 25 employee businesses?

Choose Gusto if

• You want transparent pricing without waiting for a quote.
• You value ease of setup and a lighter admin experience.
• You want payroll, benefits, and time tools in one straightforward package.
• Your business is still relatively simple, especially in one state or a small number of states.

Choose ADP RUN if

• You want 24/7 live payroll support.
• You expect more compliance complexity, more frequent HR questions, or more structured service.
• You want a platform that can grow into deeper HR help, training, and legal support.
• You are comfortable with quote-based pricing if the service level is stronger.

Editorial verdict

Editorial judgment based on the public product and pricing pages: Gusto is the better default recommendation for most businesses with 5 to 25 employees because it is easier to buy, easier to budget, and easier to operate day to day. ADP RUN becomes the stronger choice when live support availability, more robust compliance support, or a more service-oriented HR path matters more than price transparency.

How to make the final choice

• List the non-negotiables first: multi-state payroll, benefits admin, time tracking, and support hours.
• Estimate your real payroll pattern: if you run frequent off-cycle payrolls, Gusto’s unlimited runs can matter.
• Get an ADP RUN quote and compare it against the exact Gusto tier you would actually need, not the cheapest plan on the page.

FAQ

Is Gusto or ADP RUN cheaper for 5 to 25 employees?

Gusto is easier to price because it publishes standard monthly fees and per-person costs. ADP RUN uses quote-based pricing, so it may be competitive, but the cost depends on package level, payroll frequency, and add-ons. If you want immediate budget clarity, Gusto has the advantage.

Which is better for multi-state payroll?

Both can support growing businesses, but they approach it differently. Gusto places multi-state payroll in Plus and above. ADP RUN is often attractive for businesses that expect more compliance complexity or want stronger support as operations expand across locations.

Which is easier for a first-time payroll admin?

For most first-time payroll admins, Gusto is easier to evaluate and operate because the pricing and plan differences are clearer upfront. ADP RUN may still be the better fit if that admin needs more hands-on support or if the business has more compliance-sensitive payroll needs.
