Is there a free alternative to Gusto for payroll?

Not for full-service payroll with tax filing — Gusto's Simple plan at $49/month plus $6/person is already about as cheap as this gets from a name-brand processor. What you can get free is the fraud-adjacent tooling around payroll: Ramp for spend and AP, Jibble or Connecteam for time-clock verification.

Why would I pay more for ADP or Paychex when Gusto is cheaper?

For a specific control Gusto doesn't have. ADP's payroll preview catches padded hours and rate changes before a check goes out. Paychex sells biometric clock hardware for buddy punching. If neither of those closes a gap you actually have, Gusto's lower price and simpler setup win.

Best Gusto Alternatives

Gusto is our SMB payroll pick: full-service payroll with baseline fraud monitoring and hours-approval workflows built in, at a price that doesn't require a sales call. It's not dedicated fraud detection software, though, so here's where the real alternatives add something Gusto doesn't have.

01
Rippling
Payroll plus IT and HR in one system of record, with more granular controls than most
Step up here once you have enough internal complexity (multiple departments, IT provisioning) that a unified payroll/HR/IT record earns its cost
Custom-quoted based on modules (payroll, HR, IT/device management) and headcount — contact the vendor for current pricing. The platform is marketed from around $8 per employee per month, but realistic all-in totals with payroll plus a module or two land closer to $15–$35 per employee per month, higher than Gusto.7.8/10
02
ADP (RUN)
The incumbent, with anomaly flags built into the pay run and a quote process built to out-negotiate you
The payroll preview that flags anomalous hours and pay changes before money moves is a real fraud control Gusto doesn't have
Quote-only. Essential tier reportedly starts around $79/mo + $4 per employee; Enhanced, Complete, and HR Pro tiers stack on more HR features. Most small businesses report $100–$300/mo all-in. Time tracking, retirement, and workers' comp are separately priced add-ons, and first-year discounts fade at renewal.7.6/10
03
Paychex Flex
The only SMB payroll platform you can buy an iris-scanning time clock from
Worth it specifically for the iris-scanning biometric time clocks, if buddy punching is a real line item and not just an occasional annoyance
Flex Essentials is published at $39/mo + $5 per employee; Select and Pro tiers are quote-only. Real-world totals land higher once setup fees, year-end processing, time tracking, and hardware are added. Biometric time clocks are purchased or leased separately on top of the time & attendance module.7.4/10
