--- title: Custom States --- ## Custom States Several models within InvenTree support the use of custom states. The custom states are display only - the business logic is not affected by the state. States can be added in the [Admin Center](../settings/admin.md#admin-center) under the "Custom States" section. Each state has a name, label and a color that are used to display the state in the user interface. Changes to these settings will only be reflected in the user interface after a full reload of the interface. States need to be assigned to a model, state (for example status on a StockItem) and a logical key - that will be used for business logic. These 3 values combined need to be unique throughout the system. Custom states can be defined for the following models: - [Stock Item](../stock/index.md) - [Build Order](../manufacturing/build.md) - [Purchase Order](../purchasing/purchase_order.md) - [Sales Order](../sales/sales_order.md) - [Return Order](../sales/return_order.md)
