The digital services account to us at different times, which means there is a delay from when your music goes live on stores and when the royalties due are paid out to us.
Apple is generally the first service to account to us and is followed by the rest. If you release in January, for example, you shouldn't expect to start seeing the first royalties for your release until at least mid-April.
Note: Spotify can take about 6 months to account to us.
