What do you think is a fair percentage split between (my) a company that does design and sales with contacts with the client and a company that we use for production and overseeing shipment/logistics and making sure the order gets to the clients warehouse on time.
me/other:
50/50
60/40
70/30
80/20
90/10
you should get 100 percent. 
It can be as simple as this:
Factory=5-7% profit added to BOM +tooling costs +engineering & development costs.
Trading house/broker=4-7% of wholesale cost, depending on relationship and order size.
Your milage may vary. Anyone else with different experiences?
Thanks for the reply.
