Supply Inventory 

In the Manage module, at the upper left, click the Supply Inventory button.

First, use the menu buttons at the upper left to Setup Suppliers.  The Categories menu item takes you to the Definitions window.

Supplies Needed
This list at the upper right is completely independent of any supplier.  It is a freeform list where any staff can quickly jot down an item that might be running low.

Later, the person responsible for ordering supplies will review the list during the process of placing an order.

Main Supply List
This is a list of all supplies that are ordered from one supplier. Select a Supplier from the dropdown list at the top.  One current limitation of this feature is that you can only work with one supplier at a time.  You must first add supplies to this main list before they can be placed on an order.  Click the New button, or double click on an existing supply.

As shown in the screenshot, the quantity per unit is part of the description.  The level desired, then refers to the unit that is part of the description.  If a supply has already been placed on an order, then you will not be able to delete it and will have to hide it instead.

Orders
Click the New Order button at the upper left. The new pending order will show in the Order History list.  Double click the order to edit.

Once an order is highlighted in the list, add supplies to it by highlighting them in the main list, and clicking the Add to Order button. View the current order by changing tabs half way down the page.

Double click on items to change the quantity.  Continue to add supplies in this manner until the order is complete.  When the order gets placed, change the Date Placed.
