You can do better.

We moved over to ADP TotalSource (PEO) from ADP Run and I'll begin my review by saying we're not happy at all.
Let's start with the price: ADP TotalSource is very expensive and I can now say the cost does not justify the service received.
Service: My sales representative "forgot" to cancel our previous RUN service when she moved us over to TotalSource. Every time we called for a live representative, we were never able to get a hold of our "dedicated" representative. I would leave voicemails, but no one checks those. They did call back whenever I followed up with an email.
Platform: The TotalSource online platform is ancient.. it's like as if someone designed it to be not-user-friendly on purpose. In today's day and age, it's expected for a company like ADP to provide a user-friendly experience.
Closing thoughts: Save the headache and find a newer, more up-to-date PEO service provider. We moved over to a much better company and we're happy. In addition to saving about half of what we were paying ADP, we're receiving better service and we're also using a user-friendly online platform.
