I am selling baby products at my own website. Most customers choose to pay manual online bank transfer. Some will pay via a payment gateway such as Paypal and a local company called iPay88.
iPay88 and Paypal has their own commission rate. When customer use to pay a product worth $10 and transfer manually into my bank, i get $10. But if they use payment gateway, i will get a certain % less than $10.
I also sell my products on other marketplace such as Lazada, 11street, Qoo10. Each of them has their own rate.
From accounting point of view. How do I handle this? After I key in sales invoice from a channel, where/how do I put the commission rate I have to pay to these channels?
