# How to Top Up Your Account Credit

> Learn how to add funds to your account, apply credit to invoices, and avoid underpayment issues. Step-by-step guide for account top-ups.

## Why Add Credit

<Info>
  Account credit is optional. It’s useful if you want renewals to auto-charge from a balance, prefer to pre-fund several invoices, or need coverage while traveling.

## How the Balance Is Used

* Future invoices auto-deduct from credit when the due date arrives.
* Existing unpaid invoices remain outstanding—you can apply credit manually from the invoice view.
* Overpayments add to your credit; underpayments require an additional top-up to cover the difference.

## Crypto Payment Tips

* Include network fees so the gateway receives the exact requested amount.
* Slightly overpay if your wallet rounds down dust amounts.
* If the payment lands short, the system will prompt for a top-up to close the gap.
