# Billing and usage

> Add funds, check your balance, and see what your organization has used.

Synkro uses a prepaid organization balance. An organization owner manages payments; everyone in the organization uses the same funds.

Sandbox uses test cards, test payments and a $20 starter balance, separate from production funds. Use test cards only.

## Starter credit

Complete account verification and save a test card during signup. Synkro adds the $20 starter credit once the saved card is confirmed, once per new organization.

Check the credited balance with `synkro account balance`.

## Add funds

Sign in to [Synkro sandbox billing](https://app.sandbox.synkro.sh/billing), choose **Add funds**, enter an amount within the displayed range, and complete checkout with a test card. Your test balance updates after confirmation.

You can also open checkout from the CLI:

```sh
synkro account pay
```

That command opens checkout for the minimum amount. To choose an amount in US dollars:

```sh
synkro account pay --amount 100
```

Review the amount and complete payment in checkout.

## Check balance and usage

Run these commands from your signed-in CLI. An owner can view billing details with `synkro account status`; organization members can check balance and usage:

```sh
synkro account balance
synkro account usage
```

Usage shows decisions, charges, and token counts for the last 30 days. Change the grouping or date range:

```sh
synkro account usage --weekly
synkro account usage --monthly --from 09-01-26 --to 09-30-26
```

CLI dates use `MM-DD-YY`. The service uses UTC day boundaries and includes the end date. Add `--json` to an account command for structured output. JSON balance and charge fields ending in `Microusd` use millionths of a US dollar; checkout `amountCents` uses cents.

## If the balance runs out

Run `synkro account balance` and `synkro status`. Enforcement pauses when the balance cannot cover a decision. An owner can add funds, then check status again. For other account or service errors, see [Troubleshooting](/troubleshooting).

Sandbox and production balances are separate. Check the environment shown before adding funds.

## What counts as usage

A governed action can carry a base charge. For semantic checks, that base
charge is included in the semantic-check charge. Use `synkro account usage`
to see your organization's charges.

Installing, reading status or events, and testing deterministic examples do not incur usage charges. `synkro check` bills semantic examples through your configured account service. A late decision is refunded, including its base charge; a balance reservation alone is not a final charge.
