I am creating an auction website and i need to add the function where i will be able to charge 5% of all sales that occur on my website.
For example, say 5 auctions have ended. Each auction ended at 100$. I want to be able to charge each auction and therefore make 5 dollars off of each auction.
I have already downloaded the PremiumWordpress plugin called AuctionPress. This has an open source code i just do not know how to add this
