“Residuals” are amounts paid by online music platforms for works or parts of works which have not been claimed by any collective management organisation. The reason for this is often that the works or parts of works have not been registered by the authors or publishers with their collective management organisations. SUISA can only collect licence fees via the SUISA Digital Licensing AG (SUDL) from the platform for works that have been declared and completely documented. This is why it is important that you register the works as soon as possible! Best before they are published online (details on this also in the blog article “Online licensing activities require early work registrations” of 29 October 2020).
