In Odoo:

1. ✅ Companies: You can create multiple companies from Settings > Companies. Each company has separate data (customers, products, journals).
2. ✅ Users:
   • When creating a user, assign them to one or more companies via the "Allowed Companies" field.
   • The “Current Company” field controls what the user sees and works with at any given moment.
   • Superusers can access all companies. Normal users see data only from their allowed company.

Hi,

In Odoo Online (SaaS) and Odoo.sh, here’s how pricing and limits typically work

Users

      - Each additional user (with login access) incurs a monthly or annual fee based on Odoo’s pricing plans.

      - A user is any account with login access to the system.

Companies

      - You can create multiple companies in the same Odoo database at no additional cost.

      - There is no limit on the number of companies you can add.

      - All companies share the same database and can be managed using Odoo’s multi-company features.

Hope it helps
