Every merger and acquisition brings together new systems, solutions, people, and processes. The difference between disruption and stability lies in how that transition is managed.

At FosterThomas, we’ve built a dedicated M&A Integration Unit focused exclusively on HCM and payroll integration within ADP environments. No guesswork. No do-overs. Just clean data, structured timelines, and a seamless employee experience from day one.

Our structured methodology eliminates rework, reduces risk, and ensures operational continuity, no matter the size or scope of your transaction.

Our Model Includes:

  • HCM Standardization – Aligning data and configurations across entities
  • Data Validation & Dual Maintenance – Ensuring accuracy before and after go-live
  • Reverse Payroll Engineering – Rebuilding undocumented or legacy payroll structures
  • Payroll & HRIS Testing & Cutover Planning – Delivering precision at every milestone
  • Post-Go-Live Stabilization – Ensuring a clean and consistent employee experience

Whether you’re integrating 50 or 5,000 employees, our approach remains the same:
Proven methodology. Precision execution. Immediate stabilization.

If your merger or acquisition is approaching, let’s talk before cutover. We’ll walk you through how we’ve helped organizations just like yours achieve seamless transitions.
