ePowerHouse is an Internet interface into the PowerHouse WMS Warehouse Management System application suite.
ePowerHouse WMS allows you to:

View real-time data about your warehouse through a web browser
Provide your 3PL customers with a means to view their inventory
Give 3PL customers a way to enter receipts & orders over the Internet
ePowerHouse provides secure access to inventory and order data from any Internet connection, anywhere in the world. Clients of 3PL warehouses can check their products status and enter in orders and expected receipt information through their favorite browser.

The 3PL operation does not need to worry about supplying the client with a copy of the WMS and training in its use for the client to be able to monitor their inventory. The security features embedded in the application ensures that when you grant a client access to the system, they are only allowed to view data relating to their own inventory.
