Zen Sales 

"Essential Hub gave us the functionality we needed to take our system to the next level. We added package-level reporting, the ability for end users to schedule pickups, and commmercial pricing. Our software has never been more valuable to our customers."


"We are able to access better rates through Essential Hub that we would not have qualified for on our own. We spend our time on managing our platform, while Essential Hub powers our rates."


"Integrating to eHub gave us access to commercial epacket, a USPS service in demand from our customers but far out on our development timeline. Once the integration was completed it became really simple to add additional services as we need them."
