Hi,

When removing a company from an Odoo.sh environment, especially one with historical transactions (accounting, inventory, purchases, etc.), you must proceed carefully. Odoo is built around multi-company integrity, and direct deletion of a company with live or historical data is not supported or safe without breaking dependencies or corrupting records.

* You cannot delete a company directly from the database if it has existing transactional records.

* Attempting to do so will raise errors due to foreign key constraints and business logic.

The most recommended solution is to deactivate/archive the company.

If You Absolutely Must Delete All Records:

Only do this if you understand the risks.

This requires:

      - Removing all dependent records in the right order (accounting entries → invoices → orders → stock moves → etc.)

      - Often done with custom scripts in development or staging first

      - Best handled by an Odoo expert or partner (or Odoo Support if you're on Enterprise)

Odoo has thousands of interlinked tables. Deleting a company improperly can leave orphan records and break core apps like reporting, approvals, inventory, etc.

Hope it helps
