Phillips Van Heusen

“I was certain that the right ERP solution would help us with our inventory control issues and process flow automation in our warehouse. We are happy with Royal 4 Systems and have been a customer for over 30 years. The working relationship we have with R4 is the best one we have when we look at all of our vendors.”

Kreg Tool

“I wanted to share some good news with the Royal 4 team. We have gone from the high 80% range to consistently being above 99.5% on our daily inventory accuracy, and we have done this while increasing our on-hand inventory by 50%! It has not been an easy journey but we are here.”


“Metraflex has been a successful business partner with Royal 4 for over 18 years. The WISE and R4 ERP system has increased our efficiency immeasurably. During all these years, Royal 4 has responded quickly and efficiently to all of our issues and has kept up with the latest supply chain technologies.”
