“I would say we chose Zethcon, not Synapse. We chose the people not the software. Our first criterion was choosing a partner where our business mattered as much to the developer as their software mattered to the success of operations.”

Arthur Barrett, President, Barrett Distribution


“Our switch to Synapse has transformed our business. Zethcon’s WMS and services provide us with the technology necessary to move our company forward.”

Tony Calabrase, VP of Technology, RBW Logistics


“Synapse has completely changed the way we operate. It has taken time to change our processes and re-train our employees, but for the better. Many of our customers have come to us from other 3PL’s and are astonished by the level of service and transparency that Synapse offers. Every system has pros and cons; there’s no perfect system out there. Zethcon listens to their customers, large and small.”
