In-Depth Analysis
OnPay
Simplify payroll, HR, and benefits management for businesses of all sizes.
OnPay's Partner tier at $49/month + $6/worker seems fair for accounting firms looking to manage client payrolls, especially with the free firm payroll and 15% revenue share.
Strengths
- Pro: Comprehensive payroll, HR, and benefits in one platform
- Pro: Automates tax filings and payments, reducing compliance burden
- Pro: Supports various worker types (W-2, 1099, remote)
- Pro: Offers expert assistance for benefits and switching providers
- Pro: Highly rated by industry experts and users
Weaknesses
- Con: OnPay has no native time tracking, so hourly-heavy businesses must bolt on and pay for a third-party tool like When I Work or QuickBooks Time to capture hours.
- Con: Its integration catalog is far thinner than comparably priced rivals and it offers no public API, whereas Gusto connects to 250-plus apps, which limits automated syncing with your existing HR and accounting stack.
- Con: Reporting is limited to roughly seven pre-built reports with little customization and no deeper workforce analytics, so businesses needing custom cost or PTO reporting will find it shallow.
- Con: OnPay lacks a dedicated native mobile app for employers, and several reviewers cite setup, onboarding, and billing friction with support when resolving account-specific issues.
