Company with branches in SBO 9.0

Dear SAP experts,

Hi,

I am facing the following challenge in our company and should to find the best solution for that. I do appreciate if you would share your knowledge or experience regarding it:

Actually in our business we have a branch company which is operating in another country. The branch company charges the head office each month for certain tasks they do, and in return the head office sends the branch company payment.

Now my challenge is how to define this business structure into the SAP business one 9.0. I already acquired SBO 9.0 with license for 4 users.

I will be thankful if you can give me any roadmap or tips.

Best regards,

Sina.
