OnPay vs RUN Powered by ADP

OnPay is easier to price from the published information. Payroll Essentials is $49 per month plus $6 per worker, with unlimited pay runs and tax filings included. That works out to $55 monthly for one worker. The pricing page shows monthly pricing, not an annual rate; OnPay also lists a one-month free trial. HR and time tracking are add-ons or bundles, with prices ranging from $15 base plus $2 per worker for HR to $81 base plus $4 per worker for bundled HR and time tracking. Benefits administration is listed as free, but insurance and other plan premiums cost extra.

ADP does not publish monthly or annual RUN prices. It lists four plans for businesses with 1–49 employees, but not their prices or specific usage limits. ADP advertises “3 Months Free”; that is a promotion, not a published free trial. Neither product lists a free plan. Get ADP’s plan and add-on costs in writing before comparing totals.

OnPay describes its payroll scope more specifically: it automates calculations, tax filings, and payments, supports payroll in multiple states, and includes year-end filings. Payroll Essentials lists unlimited pay runs and schedules, W-2s and 1099s, and federal, state, and local tax filings. OnPay also lists customizable onboarding workflows, e-signature templates, personnel management, and employee mobile clock-ins, with hours and overtime importable into payroll. Benefits options include medical, dental, and vision coverage, with online enrollment and plan administration. HR guidance is available by phone, chat, and email; accounting, 401(k), and HR and compliance integrations are also listed.

ADP’s small-business lineup names payroll, HR, time and attendance, retirement, health benefits, and workers’ compensation. But the available product information does not specify which of those are included in RUN, or detail RUN’s payroll and HR capabilities. The categories suggest areas to ask about, not confirmed inclusions. If you need to compare feature-by-feature, ask ADP for a written plan breakdown.

OnPay says it provides free data migration for businesses switching providers, plus live HR guidance by phone, chat, and email. Its stated onboarding workflows and e-signature templates may also matter if hiring setup is part of the move. Those details make the switching offer easier to assess, but they do not establish how long setup takes or how easy the software is to learn.

The available ADP information identifies four RUN plans for businesses with 1–49 employees but does not explain their features, setup process, or support specifics. We can’t make a grounded claim about which product is simpler to operate. Before choosing, ask both vendors who handles payroll migration, what employee and tax data they transfer, and what support is included in your quoted plan.
