Stock models

Stock models are used to track accessories or equipment where you only follow total quantity instead of individual items. These items are added at the model level, which gives them a shared model ID.

Examples of stock models: general tools, extension cords, workwear.

Stock models can also be reserved and lent if needed.

The article features images of Trail’s updated interface, which will be rolled out to customers in stages.

Enabling stock models

You can enable or disable stock models from: Admin > General settings > Models. If you need help with the settings, contact Trail Support: support@trail.fi
