We Make HR Easier for You
For 20 years, MP has combined powerful HCM technology with a team that knows your name, answers your calls, and helps you succeed.
Why MP Exists
Twenty years ago, Jason Maxwell was working in payroll at ADP when he noticed something. His clients needed more than technology—they needed a partner. Someone who’d answer the phone. Someone who’d take time to understand their business. Someone who’d stick around after implementation.
He kept thinking: What if a company built its model around helping people?
So in 2004, he started MassPay in Massachusetts. The idea was simple: deliver great technology with helpful service. Treat clients like partners, not account numbers. Build a team that sticks around long enough to know your business.
Clients stayed. Word spread. We grew from Massachusetts across the country.
Today we’re MP: Wired for HR, serving 2,200+ companies with the same philosophy: powerful technology paired with people who care about your success.

Beyond the Platform: Complete HR Support
HR Advisory Services
Our SHRM-certified experts help you build efficient HR systems, improve employee engagement, ensure compliance, and align your people approach with business goals. From policy development to culture initiatives, we’re here to help.
Partnership, Not Sales
Your account manager isn’t trying to sell you add-ons. They’re focused on helping you get the most from your investment. Monthly performance reviews. Proactive suggestions. Honest guidance.
Why Independence Helps You
We’re an independent company, which means we answer to our clients, not shareholders or private equity firms.
This freedom lets us:
- Invest in long-term client relationships instead of chasing quarterly numbers
- Keep our team around (4.4-year average tenure vs. 18-month industry average)
- Choose the best technology for our clients, not what earns us the highest margin
- Make decisions quickly to help you, not slowly to satisfy investors
- Acquire companies to expand our service model, not strip them for short-term gains
In the last year, we acquired two businesses and welcomed their teams and clients into the MP family. We’re growing the right way.
