Pick Gusto if
- Controllers at funded startups or professional-services firms (roughly 1-100 employees) running on QuickBooks Online or Xero who want balanced payroll journal entries posted automatically with no manual GL work
- Finance leads managing distributed multi-state remote teams who need federal/state/local filing in all 50 states with no per-state filing surcharge, and can buy the Plus tier (multi-state and next-day direct deposit are gated above Simple)
- Accounting and CPA firms managing many small-business clients from one dashboard, who benefit from the Gusto Pro partner channel, free firm payroll, and free CPE-credit certifications
Pick Paychex if
- Accounting and CPA firms managing payroll for a book of small-business clients: the AccountantHQ/Partner Pro multi-client dashboard over real-time payroll, GL, and HR data, with 24/7/365 US-based accountant support and a CPE/Knowledge Center, is built for exactly this.
- US-based small and midsize businesses (roughly 5-500 employees) paying W-2 staff and 1099 contractors across multiple states that want payroll, multi-state and local tax filing, and HR consolidated under one name-brand vendor, and that will sit on the Pro tier or above to get the real-time GL posting bundled in (QuickBooks Online, Xero, Sage Intacct, or NetSuite).
- Finance teams running Sage Intacct or Oracle NetSuite (or QBO/Xero) that specifically want dimension-mapped, automated journal entries on every pay run instead of manual GL file exports, and that value offloading compliance, workers' comp, and large-group benefits via the PEO (5-employee minimum).
