I am building a site that for a store that will sell products on commission. Sellers are private individuals, "Sellers".
What i am trying to create is a way for the Sellers to if their products have been sold. They will not create products. The store owner will do that.

What i want to do is the following:

1. A Seller register at home and gets an userid

2. Takes his/hers products, walks to the store and leaves the products and the userid.
