With ProShop you can issue POs to your vendors directly from the Purchasing Dashboard which displays live purchasing requirements from planning for all active Work Orders based on need date and commodity type.  You can see all outstanding POs, late orders, and time sensitive orders.  Purchase orders are typically initiated using a shopping cart system which collates all the purchasing requirements of active work orders and then are assigned to a vendor for ordering. Upon receipt, all certs for purchased items are scanned and attached to each line item, setting the stage for easy retrieval of certs as described in the WO module.
