**gateway**

The payment failed because the customer's account has a low or insufficient balance to complete the transaction. This can occur when available funds are below the transaction amount or when funds are held for other pending transactions.

## Recommended Customer Message

Your available balance is below the transaction value. Please add funds to your account or use a different payment method.

## Root Cause[](#root-cause)

-   **Insufficient available balance:** The customer's account does not have enough funds to complete the transaction.
-   **Pending holds:** Funds are reserved for other transactions, reducing the available balance.
-   **Temporary banking restrictions:** Certain accounts may temporarily limit available funds for transactions.

## Troubleshooting and Solutions[](#troubleshooting-and-solutions)

-   Inform the customer that their available balance is below the required transaction value.
-   Ask the customer to add funds to their account before retrying the transaction.
-   Ask the customer to use an alternative payment method with sufficient available balance.
-   Configure smart retries to attempt the transaction again around common salary days if the issue is expected to be temporary.
