The scheme gives both the billers and the business payers efficiency gains thanks to the automation of payment processing, and an improved liquidity, as the bills are automatically paid when they are due.
Scheme participants can find on this page the rulebooks, the Implementation Guidelines ( ), and other relevant documents to implement the scheme in their systems.
The Direct Debit Business-to-Business rulebook currently in effect up to 21 November 2021 is the 2019 Direct Debit Business-to-Business rulebook version 1.1. This version has no specific impact on the business and operational rules compared to the version 1.0 of the 2019 Direct Debit Business-to-Business rulebook.
The Implementation Guidelines of the version 1.1 of the 2019 rulebook are based on the 2009 version of ISO 20022.
The 2019 rulebook contains a clarification about which scheme participants must comply with the mandatory Customer-to-Bank (C2B) of the rulebook. It further includes additional r-transaction reason codes related to clearing and settlement-specific issues.
An collection containing an IBAN but not the related BIC, can be transmitted by the Creditor to the Creditor Bank, even if one of the two scheme participants covered by that transaction is based in a non- country.
