ADP review
Enterprise-grade payroll and HR with deep compliance and a free accountant portal, but opaque, quote-only pricing.
A safe, scalable payroll choice for firms managing many clients, as long as you can stomach custom quotes, add-on fees, and long contracts.
Pros
- Free Accountant Connect portal centralizes multi-client payroll, GL mapping, reports, and benchmarking data
- Mature tax filing and multi-state compliance built for businesses that outgrow lightweight tools
- Scales from 1-employee shops (RUN) to large enterprises (Workforce Now) without switching vendors
Cons
- Pricing is quote-only and opaque, with setup fees and paid add-ons inflating the real monthly cost
- Long 36-month contracts with auto-renewal and reports of aggressive upselling and slow phone-only support
Key features
- Full-service payroll with automatic federal, state, and local tax filing and W-2/1099 handling
- Accountant Connect: free multi-client dashboard with GL interface, payroll reports, and DataCloud benchmarking
- Tiered HR add-ons (RUN Essential through HR Pro; Workforce Now Select/Plus/Premium) layering benefits, time, and HR advisory

What it is and who it's for
ADP is one of the oldest and largest payroll and HR providers, and for accountants the relevant entry point is the free Accountant Connect portal layered on top of RUN (1-49 employees) and Workforce Now (50+). It is built for firms that manage payroll across many clients and for employers that have outgrown lightweight tools and now need serious multi-state tax compliance. A one-person practice with a few simple single-state clients will find this more machinery than it needs.
Strengths
The compliance engine is the real draw: automatic federal, state, and local tax filing, year-end W-2 and 1099 handling, and the breadth to cover unusual jurisdictions that trip up smaller competitors. Accountant Connect ties it together with a single dashboard for authorized client data, scheduled multi-client reports, general-ledger mapping into accounting software, and DataCloud compensation benchmarking for advisory conversations. Scaling a client from a few employees to several hundred doesn't force a platform migration, which is a genuine advantage for a growing book of business.
Weaknesses and pricing
Pricing transparency is the biggest weakness: quotes are custom, setup fees commonly run $500-$2,000, and core needs like time tracking and benefits admin are paid add-ons that push real cost past the headline base. Expect RUN to start around $79/mo plus roughly $4 per employee on Essential, rising to about $175 base plus $7 per employee on HR Pro, while Workforce Now lands near $23-$30 per employee/mo software-only. Contracts typically run 36 months with auto-renewal and early-termination fees, support is phone-only, and reviews repeatedly cite long hold times and upselling; PTO tracking and dashboard customization also lag more modern tools.
Regional note and verdict
RUN and Accountant Connect are US-focused, so their value is tied to US federal and state tax; practitioners outside the US should treat ADP as a tool for US client payroll rather than local domestic payroll. For firms running US payroll at volume across many clients, it is a defensible, low-risk choice with deep compliance, a genuinely useful free portal, room to scale, and partner revenue share via programs like PartnerStack. Just go in clear-eyed about the opaque quoting, add-on creep, and multi-year contract, and negotiate before signing; smaller, price-sensitive practices should compare lighter alternatives first.
