Trust us, you want to keep your artists happy. Without them you literally don't have a business, so make sure you pay your artists is a timely manner and get up to speed with royalty accounting.
Our Royalty Worx tool is perfect for this, so make sure you check it out if you're not already using it. Even if an artist has earned nothing, making sure you deliver statements to them will show them how professional you are and hopefully make them want to continue working with you.
