A seller may upload own files on the site, sell them and get a commission.
A site admin may set several sellers types with different rights, uploads limits and commissions. Please go to Customer manager -> Seller types for more information.
A site admin monitors a commission at Admin panel -> Orders -> Commission manager
There are 3 sections:
1) Commission. The script automatically adds a commission to a seller when his/her file is sold.
2) Payout. Here a site admin pays out to the sellers.
3) Users earnings. Here a site admin may monitor a seller's balance.
A seller can see his/her commission here: Member area -> My commission
