What you need to do is to develope an overall requirements document specifying what you management expects to use the database for.
a. What data do people need/want to view
b. How is data collected.
and on and on
Once you have a requirements document finished and reviewed and approved by your managemnt, Then you can concern yourself about individual tables, how they are linked together using foreing keys, etc etc.

If everything seems to be going well, you have obviously overlooked something.

I assume this is not being developed for a specific company but it is intended to be used to serve multiple companies you don't even know yet - is that a correct assumption?

If that's the case I'll make an executive decision and say "all companies have at least one branch - which is the company's headquarter"

Then, for a three "branches" company your database will show four e.g. headquarter plus three non-headquarters branches.

Hope this helps.

Collapse the structure to a single table and use a HIERARCHYID.

That way you can define a flexible heirarchy in this table and attach to specific points.
