I've searched and nothing really hits my issue on the head (and the closest ones seem to be rather out of date). Here is the situation:

- One company with one billing address, billing contact, etc. (corporate headquarters)

- Thousands of physical "store" locations with different shipping addresses

- Stores generate their own PO's to purchase from us - all with the same billing to corporate A/P office

- Each location is communicated with as though the store managers run their own small business

- Other clients (accounts) may or may not be set up this way so any approach needs to not limit how we deal with them

- Obviously, each of the stores will have a constantly changing set of contacts (store employees)

What is the best practice for handling this type of account in ZOHO.
