The flow is the following

1.)  Product uploaded into Product Module.  Enter many unique product details.

2.)  Product(s) and the company who makes it turn into my leads.

3.)  Leads then turn into different types of accounts & potentials based on the product.

How do I assign a company, that is a lead, to a product?

Then, how do I make sure all the data entered in the product page goes into the lead then account then potential automatically?

Thanks
