What Sets Paychex Apart from ADP

Item

No Migrating As You Expand

With ADP
You may move from Roll to Run to Workforce Now. Continuing to phase out of platforms can lead to re-implementation challenges, ongoing training in new platforms, and communication issues.

With Paychex
You get Paychex Flex®, now and later. With a one-time implementation, it has the tools your business needs as it grows.

Customizable Support in Reach

With ADP
Depending on how many employees you have, you may not have access to dedicated support who can help you resolve more complex issues your business may be facing.

With Paychex
You have the option to add the level of flexible support that best suits your budget and operational needs—no matter how many employees you have.

Assigned. Proactive. Dedicated.

With ADP
HR support may come in the form of generalized best practices and without a single point of contact for your business.

With Paychex
You can use a dedicated HR professional assigned to deliver ongoing, personalized answers to your HR questions, help you proactively identify and assess risk, and provide strategic and day-to-day support. Plus, our HR professionals average more than 15 years of industry experience.

*The Three Months Free Payroll Over One Year Promotion (the “Promotion”) will run from 6/1/25 until 9/30/25 (the “Promotion Period”) and is subject to the following terms and conditions. The Promotion will consist of three (3) months of free payroll services to Eligible Clients. An “Eligible Client” is a client that: (1) is not currently receiving payroll services from Paychex; (2) elects either the Paychex Flex® Pro, Select, Enterprise or Express payroll services package by entering into a service agreement with Paychex; (3) has between 1–250 employees at the time it commences payroll services; (4) processes its first payroll, on or before 11/18/25, with Paychex during the Promotion Period; and (5) continues to process payroll with Paychex for twelve (12) consecutive months.

Paychex will credit an Eligible Client’s invoice for free payroll services in months four (4), five (5) and six (6) following commencement of payroll processing services. An Eligible Client must be processing payroll with Paychex in order to receive one month of free payroll services, and any unused month is not redeemable in U.S. currency or for any other entity. The Promotion only applies to payroll services, and Eligible Clients will be solely responsible for all fees due for services other than payroll services. The Promotion cannot be combined with any other offer and is a limited time offer that is only available during the Promotion Period. For businesses with 251+ employees, ask about Paychex’s other special offers.
