We upload reports to our system at the end of every month. These reports will typically reflect sales from 3 months ago. If you get a sale today, you won't get paid for that until 3 months from now? Why? This is how long it takes stores to tell us about a sale and send us the money for that sale.
When a report is ready to be viewed, you can navigate to your Earnings tab and click "Royalty Statements".
