Franchise needs to Set up one parent company that shares data across other company files.

I have a parent franchise company. We are selling franchises to other owners. Each business owners requires the tools to run their business, I need to provide them a constantly updated inventory/parts list. This needs to be maintained daily. Right now I see the parent company hosting multiple company files, each business owner has access to their location and they transact accordingly. My question is: How do I set up a common parts/inventory list that is visible to all franchises, and is updated by the parent company. Importing/Exporting will not work unless it is automated on a daily basis. Is this even possible? I currently am running QB Enterprise with remote sessions enabled to handle multiple sessions, but creating separate companies and sharing common data is stumping me. Any advice? Thanks in advance.
