# Billing
> Manage your Gateway wallet, payment method, and view invoice history.
## Overview
The **Billing** page gives you full control over your account balance, payment method, and invoice history. Access it from the left sidebar: **Billing**.

## Wallet
The **Wallet** section shows your current credit balance and an estimated message count based on your current spend rate.
| Element | Description |
| ------------------------- | ----------------------------------------------------------------------------------------------------------- |
| **Balance** | Your available Gateway credit (e.g. `$64.41`). This is deducted as messages are sent. |
| **Estimated messages** | An approximate number of messages your current balance can cover, based on your average cost per message. |
| **Regional pricing note** | A reminder that Meta's per-message pricing varies by country. Click **Here** for the pricing documentation. |
| **Top up** button | Opens the **Add funds** dialog to reload your wallet. |
### Adding Funds
Click **Top up** to open the **Add funds to wallet** dialog.
**Quick-select amounts:** `$10.00` · `$25.00` · `$50.00` · `$100.00` · `$250.00` · `$500.00`
Or enter a **custom amount** in the input field.
A real-time summary shows:
| Field | Description |
| --------------- | ---------------------------------------- |
| **Amount** | The amount you are adding. |
| **New balance** | Your projected balance after the top-up. |
Click **Add funds** to charge your saved payment method and credit your wallet immediately.
Funds are deducted in real time as messages are sent. There is no automatic top-up — you must manually reload your wallet when your balance is low.
