A NEW APPROACH IN INVENTORY AND P.O. MANAGEMENT - Bluestreak | Inventory and Purchase Order functions, like all BluestreakTM modules, are 100% browser-based; this means there is no software to install and it can run on nearly any device. You have the option of generating PO’s directly out of the system and emailing them to the appropriate vendor, but it is not a requirement, if you have another way to generate PO’s.
