Consumables
Consumable items are spare parts or accessories that do not need to be tracked individually, but rather by quantity. They are added in a model level. Unlike stock models, consumables are not returned to stock—their total quantity decreases as they are used.
Examples of consumable items: disposable respirators, batteries, ballet shoes, replacement lamps.
Activating consumables
Consumable items can be activated or deactivated from: Admin > General Settings > Models
If you need help with settings, please contact Trail Support: support@trail.fi
Viewing Consumables
All consumable models can be found under: Items > Consumables. At the top right corner of the page, you’ll find icons that allow you to:
- Adjust which columns are displayed in the list view
- Open the catalog view

Consumables' own view
From the consumables' own view, you can find information related to a specific model. In this view, you can for example:
- Check from which locations or departments the item is in stock.
- Visibility may vary depending on which departments the user has access to.
- Add / Write-off / Transfer stock.
- Transferring means that the stock is moved from one location to another, for example.
- Add attachments (e.g. images or instructions).
- Display manufacturer barcodes.
- If this section is not visible, you can enable it under Administration > General Settings > Identifiers.
- The barcode is an identifier provided by the manufacturer and can be used in searches.

Creating a new consumable model
Creating a model or updating its quantity requires Editor access to Items.
- Go to Items > Consumables
- First, check that the model doesn’t already exist.
- If it does, skip ahead to Add quantity to an existing model.
- Click Create consumable model.
- Fill in the model details as follows:
| Field | Description |
|---|---|
| Category | Select the appropriate group (required). |
| Type | Choose the correct item type (required). |
| Manufacturer | Enter the manufacturer’s name. |

Adding quantity to an existing model
Stock per Location / Department section shows where the model currently exists by location and department.
- Click Add.
- Fill in the fields:
- Change: number of units to add.
- Department: which department the quantity belongs to. If left blank, the quantity is visible to all departments.
- Location: where the quantity is physically stored—either a specific site or device.
- Click Save Changes.

Linking a consumable's stock to item card
Consumable's quantity can be assigned to item card when the item is physically part of that item, for example, a vehicle. To make this possible, ensure that the item card allows adding contents.
- Open the consumable
- Click Add
- Fill in the following fields:
- Quantity
- Department
- Under Location > Item, select the relevant item.
- Click Save.
The item will now appear on both the item card and the consumable's own page.


Deleting a consumable
If a consumable's quantity was added incorrectly, or if you want to manually remove used quantities:
- Open the consumable
- Select Write-off and fill in:
- Quantity, department, and location from which the items are removed.
- Reason: Broken, Lamp replacement, Lost, or Stolen.
- Click Save
Deleting an entire consumable model
A model cannot be deleted if it still has a remaining quantity in any location or department.
Once all quantities have been removed, a Delete button appears in the top-right corner of the model card.
After deletion, the model can still be found later using an advanced search in the model list.
⭐ Tips
- Use consumable items for equipment or materials that do not require individual tracking.
- Set alert thresholds for critical consumables to prevent stockouts. For detailed instructions on creating alerts, see: Notifications.
