Here you see a history of all previous purchase orders.
To make a new purchase order, search for and select the vendor that you are purchasing from.
After a vendor has been selected, three action buttons should appear along with the vendor.

Quick List – An item list containing the products that you want to appear when a quick order is made such as frequently ordered goods. Clicking this button allows you to edit it.
New Order – This creates a new order form where you will have to enter each product code one by one.
Quick Order – A shortcut that will automatically pull out and input products from the vendor’s quick list. So when you click quick order, each product from the quick list will be listed out with a purchase quantity of 0. Then, to order a product you change the product quantity to the desired amount. If you don’t want to order a product from the quick list, then just leave the quantity as 0.
