An inventory item now has three attributes in regard to inventory type
Standard, Production and Exclusive.
The differences between the three are as follows
Standard: items displayed on the phone app and are for general use.
Production: items used in the production of another product but is not available for ordering via the phone app. e.g. flour, sugar etc.
This item does NOT display on the phone app but is available as a stock take item and included in the generation of purchase orders
Exclusive: items that are not available for ordering to all customers. If you assign this as an exclusive item you then need to click on manage exclusive items and assign it to the required customer by clicking on the pencil icon.
Select the customer you would like to make the item exclusive too.
