The creditor identification number is required to participate in the SEPA direct debit procedure. It is allocated in Germany on application by the Deutsche Bundesbank, and in other European countries by the respective central bank. The application can be submitted electronically.

(valid only for Germany)
If you have received a creditor ID, you must save it in billwerk at "Settings > Company > Creditor Identifier".
Please note that the same creditor ID must be set in your account with your payment provider as in the billwerk account. Otherwise, SEPA direct debit payments cannot be made.
Note: Under certain circumstances, payment providers may assign their own creditor ID for use with any escrow accounts. In this case, enter this creditor ID in the settings of your billwerk account.
