Your earnings collected from each order are added to the monthly summary of your earnings.
You can collect your earnings on "30 days end of the month" maturity, which means you collect your earnings at the end of the month following 30 days after the order.
Example: For an order on March 20th, your earnings will be available on April 30th:
Earnings are "pending collection" during the period of 30 days end of month, then they become "available", and you can then cash them in.
You can begin to collecting your first earnings after the commission fee of 9.99€ for your shop has been charged.
