# Item Master Files
{{variable.Marlin bold}} enables efficient organisation of large item inventories using the Items Master File.
Once all the necessary variables have been set up within the Marlin system, individual items can be added and edited using the Items Master File.
Item master files are also used to control [item pricing](/v1/docs/item-pricing), which is covered in its own, separate help guide.
Item master files can be viewed and edited by selecting **Master Files > Items > Items** from the menu bar.
The Items Master File window will open on the **Search** page, showing a list of active items within the Marlin system.
:::(Warning) (Tip)
The [columns](/v1/docs/configuring-columns) displayed in the list can be configured to show additional information.
:::
Items can also be added and edited in bulk by [exporting and importing](/v1/docs/importing-and-exporting) a csv file, which is covered in its own separate help guide.
Once added, an item's master file is also used to view and edit [item images](/v1/docs/item-images) and pricing information.

All active item reporting categories are listed in the **Reporting Categories** list on the right of an item master file's Options tab.
The item's reporting group for each reporting category can be assigned by clicking in the category's **Reporting Group** cell and using the picker that appears to associate it with a reporting group.
### Preferred Item Suppliers
#### Master Files > Items > Items > [Item] > Options
A preferred supplier of the item for each branch a user has access to can be assigned using the **Preferred Suppliers** list on the right of an item master file's Options tab.
To assign a preferred supplier, click in the **Supplier** cell of a branch and use the picker that appears to select a preferred supplier for the item.
The reorder levels for each supplier can be updated by editing the relevant cells of the **Preferred Suppliers** list at the bottom right.
When an item's quantity on hand falls below its **Minimum** value, it will automatically be reordered back up to the **Maximum** quantity when it is added using the bulk item function.
:::(Info) (Note)
Reorder levels can also be based on **Reorder Level** and **Reorder Quantity** values, so that if an item's quantity on hand falls below its Reorder Level, the specific Reorder Quantity (rather than the maximum) will automatically be added when it is added using the bulk item function. To change the reorder method, please contact the **Megabus Support Team**.
