Company settings

Ensure to share the 'Partner' record associated to a Company between the Companies in the Odoo database.

You can do this without changing the default Company Record Rules by setting the 'Company' field of the associated Partner to blank.

Set the 'Intercompany Invoice' flag on the Company's partner record (cf. Intercompany notebook page).

Define also the 'Intercompany Invoice User' which should be a user with Invoice create access rights in the target Company.

It is recommended to create a dedicated User for this purpose.

You can disable the 'active' flag since this is a 'technical' user which will not be used by a real End User.

As a consequence these users will not impact the 'Active User Count' which forms the basis for the Odoo Enterprise subscription pricing.

Product Records

Products must be specified on all lines of the outgoing intercompany invoices. These products must be shared between the Companies.

The product record accounting properties will be used for the incoming invoice line general account and taxes.
