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.

Main changes introduced in the 2019 SDD B2B rulebook

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.

Annex III of the 2019 rulebook contains a table listing all changes made compared to the 2017 rulebook version 1.2.
