oh, by the way, I think you should change your description to:
"...site owner removes site's commission based on agreed percentage, and then pays the balance to the vendor." Because in reality, it is the site that gets a commission, or a "fee" for allowing the vendor to sell on the site, but the bulk of the payment really goes to the vendor. I saw some woocommerce users also raising this point on other multi-vendor plugin in Code Canyon. :)
