**gateway**

A personal (consumer) bank account was used for a SEPA B2B (Business-to-Business) Direct Debit mandate. SEPA B2B mandates require a business bank account and cannot be processed from consumer accounts.

## Recommended Customer Message

We're unable to process your SEPA Direct Debit payment because the account type isn't eligible for B2B collections. Please use a business account or contact your bank for more information.

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

-   **Consumer account used for B2B mandate:** The customer attempted to process a SEPA Direct Debit B2B collection from a personal bank account, which is not permitted.
-   **Incorrect account type:** The provided account is not classified as a business or non-consumer account, which is required for B2B SEPA mandates.
-   **Bank restrictions:** The customer's bank restricts B2B mandate collections to eligible business accounts only.
-   **Mandate requirement misunderstanding:** The customer was unaware that a B2B mandate specifically requires a business bank account.

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

-   Advise the customer to provide a valid business or non-consumer bank account eligible for SEPA Direct Debit B2B mandates.
-   Clearly communicate that B2B mandates are restricted to business accounts and cannot be processed from personal accounts.
-   Recommend the customer use an alternative payment method if they do not have an eligible business account.
-   Retry the transaction only after receiving valid business account details from the customer.
