Music publishing companies, like Ditto Music Publishing, are required to work with collection societies (such as PRS for Music in the UK and ASCAP / BMI in the US) to license music to digital services, broadcasters, and venues to collect royalties.
Collection societies often collect these royalties quite a long time after the music has been used. Societies then process the royalties and make payments to publishers and writers - which usually happens on a quarterly or half-yearly basis, so it could take as long as 9-12 months to receive royalties (from the point you registered your musical work details with Ditto Music Publishing).
Ditto Music Publishing will make your royalties available to you within 30 days of the end of each month once we receive royalties from collections societies.
If expected royalties have still not been paid to you after a year, please submit a request via our support channel and we can contact the collection societies directly on your behalf.
