The B2B 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 B2B scheme in their systems.
The B2B rulebook currently in effect until 21 November 2021 is the 2019 B2B rulebook version 1.0.
The Implementation Guidelines 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 B2B 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 B2B scheme participants covered by that transaction is based in a non- country.
Annex III of the 2019 B2B rulebook contains a table listing all changes made compared to the 2017 B2B rulebook version 1.2.
