lack of the commision acount and that can edit backend

This plugin does not support manual commission payment. There is no remaining commission display, no backend to edit, and no payment form to apply for. So for the free version, a feasible solution is to add an application form on the my-account page. Then after paying the commission once, clear the corresponding affiliate code data.

You can add residual commission on the affiliate page and add a manual modification of residual commission option corresponding to the affiliate code in the background. it would be helpful for free plugin users
