ADP vs Square Payroll: Which Is Better?
The enterprise payroll processor behind 1 in 6 American paychecks versus the $35-a-month tool built straight into your Square point-of-sale terminal. Six rounds. Real numbers. One honest scorecard.
The verdict
ADP takes it, 4–2 on rounds.
There's no universal winner — Square Payroll's entire value proposition depends on already being a Square merchant, while ADP is built for businesses that want enterprise depth and are willing to negotiate for it.
Choose ADP if…
- • You're not already running Square and want deep HR/compliance tooling
- • You plan to scale past small-business size and want a PEO option down the road
Choose Square Payroll if…
- • You're already running Square POS for a restaurant, retail, or service business
- • You want published pricing today with no sales call

- Round 4Ease of Use & SetupSquare Payroll winsADP3/10
"A nightmare" setup, per one reviewer
- Dedicated HR business advisor available at the top RUN tier
- Sales call required before you see real pricing or start setup
- Reviewer-reported onboarding friction
Square Payroll9/10"A life saver," per a real reviewer
- Sign up directly through the Square Dashboard, no sales call
- Hours, tips, and commissions auto-import from the POS terminal
- Almost all of that speed advantage disappears if you're not already on Square
If you're already on Square, payroll setup is nearly frictionless; ADP wants a conversation first.
- Round 5IntegrationsADP winsADP8/10
Hundreds of apps
QuickBooks, Xero, Checkr, ZipRecruiter, and time-clock/POS hardware
- Hundreds of apps through the ADP Marketplace ecosystem
- Not tied to any single POS vendor
- Broader ecosystem can mean more setup complexity for a simple shop

Square Payroll6/101 deep integration
Native Square POS/Team App sync; QuickBooks only via export
- Native, automatic sync with Square POS and Team App for hours and tips
- QuickBooks integration is export-based, not deeply native
- No broader third-party marketplace beyond the Square ecosystem

ADP wins on breadth; Square wins on depth — but only within its own ecosystem.
- Round 6Customer Support & TrustADP winsADP6/10
4.1-4.6 G2/Capterra vs 1.2-1.4 Trustpilot
- 4.1-4.6/5 on G2 and Capterra among HR buyers
- Large, established review base (1,500+ Capterra reviews)
- Trustpilot collapses to ~1.2-1.4/5 across 3,000+ reviews
Square Payroll5/10Strong scores, smaller sample, slower escalations
- 4.7/5 on Capterra, 4.2/5 on G2
- Support reported as slower to resolve issues than payroll-only competitors
- Much smaller review sample (30 G2 reviews) than ADP's
ADP's numbers are messier but rest on a far bigger sample; Square's are cleaner but thinner and support is reported as slower under pressure.
