How do I receive my profits from selling the products?

You will start selling the products without paying any fees to Knawat, following this process :

1. You receive a sale order from your customer

2. Your customer will pay you

the order cost (through the available payment gateways on your website)

3. After receiving your money, you will pay Knawat the wholesale price and shipping fees of this order

This means that you already received your money before paying Knawat, so your profit is in your pocket! :)
