Stock models and consumables (mobile)
Trail allows you to manage stock models and consumables by tracking quantities instead of individual items.
- Stock models are used for equipment and accessories, such as cables or tools, where only the total quantity needs to be tracked.
- Consumables are supplies that are used up or replaced regularly, such as batteries or light bulbs.
You can now view stock models and consumables in the Trail mobile app, check their details and balances, and update quantities on the move.
Note: New models must be created in the browser version of Trail.
