What to look for when comparing options.
All-in-one payroll and HR (Gusto, Rippling) bundle pay and benefits. HRIS-first tools (BambooHR) focus on employee data and hiring, often with separate payroll. PEOs (Justworks, TriNet) offer co-employment for benefits and compliance. Choose by whether you need one vendor for pay or a best-in-class HRIS or PEO.
Gusto, BambooHR, and Rippling suit US-focused teams. Deel and Rippling support global hiring and EOR. If you have or plan international contractors or employees, compare global payroll and compliance.
Rippling unifies HR, payroll, and IT (devices, apps). Others focus on HR and payroll only. Choose Rippling if you want provisioning and IT in one place.
Gusto and Zenefits have transparent per-employee pricing; many others quote. Compare base fees, per-person cost, and what's included (payroll, benefits, hiring).
Larger vendors (ADP, Paychex) offer full-service and implementation. Modern platforms are often self-serve with optional support. Match support level to your team size and needs.
