How do you give supplies to a company?

I run an enterprise on FB and just built a Nuclear Submarine missiles company.
My enterprise bought plutonium supplies for it on a space station.
The problem I now have is how does my enterprise give the plutonium supplies to the company it owns?

You'll have to sell it to your corporation manually. Go to the "Trade" button at the top of the screen and select "Trade with own corporations" from the dropdown menu. Then it will take you to a list of products you have in supply; so select the "Sell" link on the plutonium section. A list of your corporations that use plutonium will be available. Enter the amount of plutonium you want to sell.

Be sure not to go too high. Maybe 10-12 months worth at most. Don't wanna bankrupt your corp. You'll have to keep a close eye on it supplying it that way. For convenience, you ought build a plutonium corp (and a weapons grade uranium corp to feed into it) and contract the appropriate amount directly to your missile corp. That way it takes care of itself.

Wow, that's so simple!
Thanks!

You're quite welcome.
