I have this scenario:

I have two companies. Mayfair who is the parent company and Flextima is the manufacturing company. Mayfair purchases all the raw materials and sells all the finished products.

My business flow works as follows:

Mayfair purchases ALL raw materials and stores them at Flextima. Customers place orders on Mayfair who in turn purchase the finished manufactured goods from Flextima. Flextima manufactures to order not to stock so will only make when there is a production work order. Once Flextima has manufactured the order, it bills Mayfair for the service provided and ships to the Customer directly.

Can anybody guide me as to the best method of setting this scenario up?
