ELI5:Commission on Net vs Gross. Whats the difference?

Whats the difference between “net” and “gross” spend – please clarify what should be included when calculating “gross” media spend that wouldn’t be included when calculating “net” media spend? A media agency wants to have commission a gross spend while I would like it on Net spend.

I don't know how this would apply to media, but generally these are the definitions:

Gross:  the total amount of a transaction.  You sell a $30,000 car, you get commission on $30,000.

Net:  the total amount of a transaction, *reduced by expenses*.  You sell a $30,000 car, you get commission on $8,000, which is $30k - $22k (what the dealership paid for the car.)
