How to create two different invoices for one order

[eseethal]

This is a rather strange and unusual request from my client: He has in his store different products from his 2 different companies. When a client makes an order consisting of these two different products, the client should receive two different invoices (one from one company, the other from the other listing its items). Does anyone have an idea how this can be achieved?

thank you very much...................Eugen
