# Recording Costs

On the detail page of a tool you can enter cost and license models so that
the total costs per tool become transparent.

> Costs is a **premium feature** (`costs`, Premium/Enterprise). Admins always
> have access.

## Adding costs

Click **Add costs** in the costs section of the detail page and fill out the
form:

| Field | Notes |
| --- | --- |
| **License type** | Free / Subscription / One-Time / Usage-Based |
| **Billing period** | Only for "Subscription": Monthly / Quarterly / Annually |
| **Costs** | Amount as a number |
| **Currency** | EUR / USD / GBP / CHF |
| **Notes** | Optional free text |

Saving creates the entry. Each cost entry is displayed as a card with
license badge, billing period, amount (`Amount Currency` or "Free") and
notes.

## Editing & deleting costs

Hovering over a cost card shows the **Edit** (pencil) and **Delete** (trash)
actions.

## API

The cost data is managed via the tool endpoints
(see [API reference](/docs/reference/endpoints/tools)).
