What two requirements of supply must someone meet to be considered a producer?

The two requirements of supply that someone must meet in order to be considered a producer are the following:

1. the willingness to supply a product or service

2. the ability to supply a product or service

Without these two, you don't have what it takes to become a producer. But if you have the means to support your company, and the wish to do so, there's nothing stopping you.
