Lets say I'm a marketplace owner. I charge a 2% commission for every sale through my marketplace. Suppose a customer place an order for an item which cost 1000INR excluding 5% tax (1050INR Total). Customer pays through the portal. The seller is invoicing the customer. So most of the payments are reached at my marketplace.
So how will the supplier get the money after deducting the commission? Do they need to send an invoice? Will tax will be applicable as its a service?
