Hi,

Yes, this can be achieved in Odoo 18 Enterprise with a combination of Website, Inventory, and Multi-Company / Multi-Warehouse configuration.

Switch Company Context: only for developer. But how the end users (Portal users ) select the branch or warehouse and place order?

Use multi-company setup in Odoo 18 to manage multiple branches/outlets, and assign each website/eCommerce shop to a specific company.

🔧 Steps:

1. Enable Multi-Company:
   • Go to Settings → Enable Multi-Companies (Developer Mode must be active).
2. Create Companies (Branches/Outlets):
   • Go to Settings → Users & Companies → Companies → Create a new company for each outlet.
3. Create Websites for Each Branch:
   • Go to Website → Configuration → Settings → Under Website, assign a specific company to each website.
4. Switch Company Context:
   • Use the top-right company switcher to manage data specific to each branch.
