Your first payout is ready 2-3 weeks after the delivery of your first order. Emphasis on the delivery - That means when the customer has received the item and PAID. That is when you can start counting.
This is only one time. Once that is done, your next payout SOA is sent to you EVERY WEEK.
The payment for your SOA is usually within the span of 4 days depending on the mode of payment you are using.
