# Billing and plans

AOSplane bills your organization for the time sandboxes run, plus extras such as code reviews. Each plan includes some usage credit every month, and you can buy more. The AI model itself is billed by your AI provider, through the [AI account](/ai-accounts) you connected.

> **Note**
>
> Owners, Admins and Billing members can open **Billing**. Only the owner can change the plan, the payment details and automatic recharge, or buy credit. Engineers see only the spend limits, under **Settings** › **Billing**.

## Check your balance and spend

Choose **Billing** in the account menu at the bottom of the sidebar (it shows your balance), or **Settings** › **Billing**. The **Overview** tab shows:

* **Credit balance**: what's left to spend, split into **Included credit**, **Coupon credit**, **Purchased credit** and any **Unpaid usage**.
* **Plan**: your plan, when it **Renews**, the included credit, projects in use, and the monthly code reviews and PM specs. **Change plan** opens the Plans tab.
* **Spend this period**: **Spent so far**, the projected total, the **Daily average** and a daily chart, then **Included this period**, **Spend by meter** and **Credit activity**.

The other tabs are **Usage**, **Credits**, **Add-ons**, **Invoices & receipts**, **Payment**, **Plans** and [Spend controls](/spend-controls). **Download statement** at the top gets this month's statement, or an earlier month from its menu.

## Add credits

#### Open the form

Choose **Add credits** at the top of the Billing page.

#### Pick an amount

Choose a suggested **Amount** or **Other**. The smallest is your plan's minimum: $10 on Starter, $50 on Team, \$500 on Enterprise.

#### Pay

Choose **Continue to payment** and pay on the secure checkout page. The credit is added to your balance, and the receipt is emailed to your billing email.

On Free you can't buy credit. The Overview shows **Upgrade to buy credits** instead.

### How credit is used

* **Included credit** comes with your plan each billing period and is used first. Unused credit doesn't carry over.
* **Coupon credit** comes from **Redeem a code** on the **Credits** tab. It's used before purchased credit and lapses if it isn't spent in time.
* **Purchased credit** never expires.

When it's all gone, usage pauses on Free until the period resets. On Starter and Team, new sessions are refused and running ones stop shortly after. Usage in between shows as **Unpaid usage** and is paid off from your next top-up. [Automatic recharge](/spend-controls#top-up-credit-automatically) tops up before that happens. Enterprise usage is invoiced.

### Change your plan

#### Pick a plan

On the **Plans** tab, choose **Upgrade to**, **Downgrade to** or **Move to** followed by the plan's name. For Enterprise, choose **Contact sales**.

#### Review the change

The dialog shows what's **Charged today**, the new **Included credit**, and each limit that changes. The review holds for 15 minutes.

#### Confirm

Choose **Confirm and pay**, **Schedule downgrade** or **Move to Free**. Choose **Cancel** to keep your plan.

* Upgrades start now. You pay the difference for the rest of the period, and need a payment method on file.
* Downgrades start when the period ends, and nothing is charged today. You can keep your plan from the banner until then.
* On the day you move to Free, sandboxes that have run longer than 1 hour are snapshotted and stopped.
* Purchased credit stays on your balance.

## Usage, invoices and payment

* **Usage**: spend for this period, the previous one or your own dates, grouped by **Day**, **Project** or **Meter**, with **Export CSV**. Sandbox time costs $0.108 per vCPU-hour, billed per second with a one-minute minimum: $0.432 an hour for Shrimp, $0.864 for Tuna, $1.728 for Shark and \$3.456 for Whale. **How each meter is priced** lists every other price.
* **Invoices & receipts**: **Upcoming** estimates, **Where documents go** (billing email, company name, tax ID), and every invoice and receipt with its status, such as **Paid**, **Open** or **Past due**.
* **Payment**: your card (**Replace card**, **Manage card**), **Recent card payments**, **Billing details** and **Automatic recharge**. If a payment fails, a banner asks you to update your card.

## Add-ons

The **Add-ons** tab has:

* **Agents you pay for per use**: PR review, the product manager and the SRE assistant. Each uses your plan's monthly allowance first, then your balance.
* **Add-ons with a monthly fee**: **Verified PRs**, $29 a month on paid plans, which adds video proof to [QA checks](/qa-checks) and their pull requests. It includes 300 recorded minutes a month, then $0.10 a minute.
* **Data and included features**: [Agent activity](/activity) (paid plans), and what your plan includes at no extra charge.
