In as much as Sales Orders are used to track inventory reductions and Rental Orders are used to track temporary inventory reductions, purchase orders are used to track inventory increases. Purchase orders give you a means to create a purchasing document that can be used to communicate with your vendors, and used to track what you ordered, the dollar amounts quoted to you by the vendor. A purchase order can also be used to "check off" items as they arrive from your vendor.
Purchase order history is retained indefinitely, which can be helpful if you wish to see what items you purchased previously, and at what price.
A purchase order is considered "completed" when all of the items on the PO are received in full. Once a purchase order is considered "completed", no further changes may be made to the purchase order unless you re-open the purchase order. Reopening PO's will not automatically "un-receive" all of the items on the PO, but the PO will now be open so you can un-receive or make other changes as needed.
