# Usage and Billing

> Check your credit balances, request more credits, and add incentive balance.

The **Usage & Billing** page shows your credit balances and how each study uses them. Every workspace role can open it from the sidebar.

## Wallets and balances

Your workspace can have one or more wallets. Each wallet has its own balances.

* If you have more than one wallet, use the wallet picker to switch between them.
* Each card shows the remaining balance and any expiry date.
* Select **View breakdown** to see **Used** (already charged) and **Held** (not yet charged).

Balance types:

* **Recruitment credits remaining:** Pays for responses from recruited participants.
* **Projects remaining:** A study uses one project after it gets enough qualified responses.
* **Interviews remaining:** Pays for interview responses.

## Usage breakdown

The **Usage breakdown** section lists credit use by study.

* Enter a name in **Search all studies**.
* Filter by status: **All**, **Active**, or **Closed**.
* Select a study to see its sources: **Panel**, **Custom**, or **Via link or e-mail**.
* A study you cannot read shows **Restricted study** as its title. Its usage still counts in the totals.

## Request more credits

A request does not charge your wallet.

1. Click **Buy Credits**, **Add Projects**, or **Add Interviews** on a balance card.
2. Enter a number in **Number of credits**, **Number of projects**, or **Number of interviews**.
3. Optional: Add **Additional information (optional)**.
4. Click **Send Request**.

> [!NOTE]
>
> **Buy Credits** does not open a payment page. All three buttons open the same request form.

Listen emails you a copy of the request and copies the credits team. The team follows up with a quote.

## Incentive balance

Incentive balance funds participant incentives. For how incentives work, see [Incentives](https://docs.listenlabs.com/setup-to-launch/incentives.md). The **Incentives remaining** card shows the balance and **Total spent**.

1. Click **Add Balance**.
2. Enter an amount in **Amount (USD)**, from $1.00 to $1,000,000.00.
3. Click **Continue to payment**.
4. Complete the payment. You return to the page.

A **Payment Successful** message confirms the top-up.

## Launch cost review

The **Cost Summary** shows the cost before launch.

* Check **Original Balance** and **Remaining Balance**.
* If the Cost Summary shows **Select a wallet**, choose a wallet first.
* If your balance is short, the button reads **Add More Credits**. It opens the request form with the missing amount filled in.
* If your balance covers the launch, the button reads **Launch Study**.
* To launch, you need Full access to the study. Admins, Supervisors, and Researchers have Full access to open studies.
* Without that access, the Cost Summary shows **You don't have permission to launch this study.**

> [!NOTE]
>
> The server checks the balance again at launch. A panel launch fails with "Insufficient credits to launch recruitment. Please add credits or select another wallet."
