The Verdict
ADP is built for small businesses and mid market companies, with a focus on payroll-processing and tax-filing. Oyster HR targets remote first companies and global teams and leads with global-hiring and payroll.
On pricing, Oyster HR is the clear winner for budget-conscious users — starting at $29/mo compared to $79/mo for ADP. That $50/mo difference adds up quickly for growing teams.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Feature-wise, ADP offers broader built-in capabilities (7 features vs 6), while Oyster HR takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
