The initials ID come from the English word Identification which translated into Spanish means Identification. In the case of Holded, the ID is the code that identifies you to the SEPA system as a direct debit presenter. Therefore, if you do not know what your ID is, you should ask your bank.
The Creditor ID is made up of the two-letter country code, a check digit, a suffix and the NIF. An example of a Creditor ID, then, would be the following: ES97000M28496658.
When completing your remittances in Holded, you will need an ID to be able to upload the document to the bank. Therefore, entering the Creditor ID is an essential step to be able to make direct debits.
From the sidebar, go to Treasury > Banks.
Select your bank account.
Click the three-dot (⋮) menu first, then Settings after.
In the pop-up window Bank configuration, enter the creditor identifier and the presenter identifier in the REMITTANCES - SEPA section.
In Holded, the Creditor ID and the Presenter ID are the same, so fill both fields with the same ID.
Click on Save.
