Bob's Red Mill

“The time savings and accuracy of the integration is substantial. We import around 100 orders per day automatically, easing tension in the customer service department as all orders are now processed correctly the first time.”

—Bryan Emerson, Bob’s Red Mill

Phil-Am Food

“Working with Kosmos has been great. Our stores’ inventory levels now update automatically so there is a lower chance that an item is out of stock. This is important since the supermarket and web store share the same inventory.”

—Erwin Santos, Phil-Am Food

“Prior to the integration we had several staff managing data. Following implementation we were able to sell out three months of camps and classes in two weeks with nominal staff resources. We look forward to optimizing the software’s potential to support future growth.”

—Christine Hinrichs, Portland Children’s Museum
