Business & farm

So when I sell these products that I have already paid for and received commission on, I need to report the money I receive as income again?  It is not truly income since I already paid  for it.  
I believe this is what some of the other direct sellers like Scentsy & Jamberry are asking for clarification on.  
Example:
I buy and item at $45 out of pocket since we pay full price up front.  I receive 30% commission from the company on that purchase, but my out of pocket expense for the inventory is $45.  So when I sell the item at a vendor event for $45, I already have commission  as shown and it should be a wash? Yes? No?
