How we grade them
| 2.4GPAPaychex FlexFair | 1.6GPATriNet ZenefitsWeak | |
|---|---|---|
| Value for money | 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. | CNo price is published; TriNet says it depends on company size and services, as a flat fee per employee per month. |
| Free plan and trial | 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. | FNo free plan and no trial on the pricing page; it starts with a quote. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
