Hello @tallsam
Dokan has 4 types of commissions. Out of which 2 (Global and Vendor wise) are available in the free version. Since we are not able to discuss pro features here in the forum as per forum rules, I am going to discuss only those above mentioned commissions.
Global and Vendor wise commission’s are actually calculated as per the order. That means whenever an order is placed, it will calculate the admin commission set by admin. Vendor wise commission overrides the global commission if both of them are set.
As a common practice, vendors are the one choses the product price. And the product price can vary from each product to another. That’s why common practice is admin gets a constant amount of commission from each sale. So, What you are asking vendor gets a commission and rest of the amount will go to the admin is not possible by default.
I hope you got my points.
