# Quota & billing

> How Valkyrie's prepaid balance and per-use pricing work.

Valkyrie is **prepaid** and billed **per use**. Your account has a balance (your
**quota**), and your fine-tuning jobs and deployments draw against it. There are no
seats and no charges for idle infrastructure. You manage all of this on the
[Quota](/dashboard/quota) screen; your remaining balance is always shown in the top
bar of the dashboard.

## How the balance works

Your balance is computed from a ledger of every **credit** (top-up) and **debit**
(usage). Rather than storing a single mutable number, Valkyrie keeps the full
transaction history and derives the balance as:

```
balance = sum(credits) − sum(debits)
```

This makes every charge and top-up auditable, and means a correction is recorded as
a new entry rather than an edited one.

<Note>
  Because balance is a running total of the ledger, there is no "delete" for a
  transaction. A reversal is posted as an equal, opposite entry, and both rows stay
  on the record.
</Note>

## Adding funds

Open **Quota** in the dashboard to view your balance, consumption, and full
transaction history. Use **Request Quota Increase** to ask for more balance.

## What you pay for

* **Fine-tuning jobs**, GPU time for the training run.
* **Deployments**, GPU time while a model is running and serving.

Because GPUs are provisioned on demand, you're charged for the compute you actually
use. Stopping an idle deployment (or putting it on a schedule) stops the associated
GPU cost.

<Warning>
  A **running deployment holds a GPU** even when it isn't receiving requests. If you
  don't need a model available around the clock, use **stop/resume** or a **schedule**
  to avoid paying for idle time. See [Deploy a model](/guides/deploy-model).
</Warning>

## Keeping an eye on spend

* The [**Quota**](/dashboard/quota) screen shows your balance, consumption, and full
  charge history.
* The [**Usage**](/dashboard/usage) screen shows per-request activity across your
  deployments.

<Note>
  Administrators can apply internal credit adjustments to a wallet. These are
  internal balance changes, not payments through a card or invoice.
