 When you select an item, it will be added to the requisition. The following information is provided about the item:
-  ***Item Code** and **Item Name**: as per your mSupply item list details
+  * **Item Code** and **Item Name**: as per your mSupply item list details
-  ***Current Stock**: how much stock currently available in your facility
+  * **Current Stock**: how much stock currently available in your facility
-  ***Monthly Use**: how much stock your facility uses each month on average (based on the last three months).
+  * **Monthly Use**: how much stock your facility uses each month on average (based on the last three months).
-  ***Suggested Quantity**: how much stock mSupply Mobile suggests that you order based on your monthly use and the maximum months of supply you wish to order for your facility.
+  * **Suggested Quantity**: how much stock mSupply Mobile suggests that you order based on (see info box below):
+    * **Monthly Use**
+    * **Max MOS**, the maximum months of supply you wish to order for your facility
+<WRAP center round info 90%> mSupply Mobile has a feature that helps you determine the quantity of stock to order.
+  * Select the number of months of supply that you wish to order using the **Max MOS** dropdown box in the header.  If you select a larger Max MOS, the suggested quantity of stock to order will be larger.
+  * Suggested quantity is calculated as **(Monthly Use x Max MOS) - Current Stock**.
+  * So for the above example for Ibuprofen 200mg tablets: (**453** * **2**) - **80** = **827**

+What should **Max MOS** be set to?
+<wrap em>Max MOS</wrap> = <wrap em>Lead time</wrap> +<wrap em> Order cycle</wrap> + <wrap em>Buffer stock</wrap>
+  * <wrap em>Lead time</wrap>:  The time between creating the requisition and receiving the stock.  For most facilities using mSupply Mobile, we can hope that this will be no more than **1** month
+  * <wrap em>Order cycle</wrap>:  This is the frequency of ordering.  If it is every month, this will be **1**, if it is once per quarter, then this will be **3**.
+  * <wrap em>Buffer stock</wrap>:  This is the safety margin of stock that the facility //plans// for.  The safety margin accounts for things such as an order being missed, or delivery delayed.  A common approach is to set this to //twice// the Order cycle.
+So, if we have:
+  * <wrap em>Lead time</wrap> = **1**
+  * <wrap em>Order cycle</wrap> = **1**
+  * <wrap em>Buffer stock</wrap> = **2** x **1** = **2**
+Then:
+  * <wrap em>Max MOS</wrap> = **1** + **1** + **2** = <wrap em>4</wrap>
