How we grade them
| 2.4GPAGustoFair | 2.4GPAPaychex FlexFair | |
|---|---|---|
| Value for money | CSimple is $49 a month plus $6 a person, so $79 for a team of five. That sits between the cheapest quarter of this category ($65 or less for five) and the middle ($85). Pay people in more than one state and you need Plus at $80 plus $12 a person, which is $140. | CNo prices are published: Basic, Foundations, Advanced and Complete are each quoted after a form or a call, so there's no five-person figure to compare. Time and attendance and state unemployment service are add-ons on some or all packages. |
| Free plan and trial | FNothing free on record: no free plan and no trial in the listing. You pay from the first month. | FNo free plan or trial. New clients who sign a one-year deal for Foundations or above by 31 October 2026 pay no payroll fees until April 2027, but that's a contract, not a trial. |
| Features | BRegular and off-cycle payroll, taxes worked out by work location, time tracking, onboarding, document signing and expense claims, with contractors abroad as an add-on. That's the whole payroll job, spread across its three plans. | BUnlimited payroll runs, Taxpay filing federal, state and local taxes, checks for missing punches before payday, OSHA and EEO-1 reports, e-signatures and a self-service portal. The whole job, with more HR in the higher packages. |
| Ease of use | A4.8 from about 52,000 App Store ratings for Gusto Mobile, where owners approve hours and run payroll and staff see their pay and sign documents. | A4.84 from about 576,000 App Store ratings for the Paychex Flex app, where staff see pay stubs and W-2s. Chat support comes with every package; phone and email agents are add-ons on the lower ones. |
| Platforms and integrations | BWeb, iPhone and Android, and you can link your own systems through a command-line tool or an MCP server. No desktop app, and the full API is only for approved partners. | BWeb, iPhone and Android, with QuickBooks, Xero, Sage Intacct and NetSuite for accounting and When I Work and 7shifts for scheduling. No desktop app. |
| Best for | small US teams that want payroll and HR in one app | growing firms that may add benefits or a PEO later |
