@mvx_user777, Thank you for reaching out to us. From your screenshot, we can see that you have set the “Revenue Sharing Mode” to vendor commission and the commission amount to 12%. As a result, the commission is being calculated according to that.
If you want the vendor to receive an 88% commission, please update the commission amount in the settings section accordingly.
Additionally, since you are not allowing vendors to receive other charges such as shipping fees or taxes along with their commission, both the net earnings and the total amount remain the same.
Please make the necessary changes on your end, and let us know if you need any further adjustments..
