+### Disable Company
+
+Rather than deleting a company, it is possible to disable it. This will prevent the company from being used in new orders, but will not remove it from the database. Additionally, any existing orders associated with the company (and other linked items such as supplier parts, for a supplier) will remain intact. Unless the company is re-enabled, it will not be available for selection in new orders.

+It is recommended to disable a company rather than deleting it, as this will preserve the integrity of historical data.

+#### Disable Supplier Part
+
+Supplier parts can be individually disabled - for example, if a supplier part is no longer available for purchase. By disabling the part in the InvenTree system, it will no longer be available for selection in new purchase orders. However, any existing purchase orders which reference the supplier part will remain intact.

+The "active" status of a supplier part is clearly visible within the user interface:
