The consolidated set of account is meant to report the financial statement of the group of companies as if there is one single company that makes businesses with the rest of the world

May I recommend you to study the consolidation accounting process (or be helped by an accountant); because the consolidaton is not a trivial process:

for instance

all intercompany transactions and intercompany margins need to be eliminated ( keeping only the transactions with the "outside world")

a common currency (and conversion rates) need to be decided for the consolidation of the group companies' operations; so that each company records its operations in the common group currency in addition to the local records kept in local currency. Only the operations recorded in the group currency will be elected for the consolidation

a common chart of account for all companies

you also have to take into consideration the % of capital that the parent company holds into each other companies (not to speak from capital holdings between the daughters companies themselves); 

In summary: the consolidation is not the addition of the transactions of all companies belonging to the same group

Hi Michel, I fully agree …! and would like to understand the best approach to multi-company consolidation in Odoo. So I have following questions;

• Is there a tool / process to assist and make it easy to do inter-company elimination of internal-invoices?

• Does it make sense to create a “Consolidation Company” for consolidation entries as eliminations, PUP, etc. and “Group Reporting”.

• Is there a way to define “consolidation accounts” which can be used to roll-up different accounts from group companies into a group reporting chart of accounts (in v10)?

Hints and pointers to best practice would be greatly appreciated!

(Note, I am not sure if you would want to use the Group Parent as the Consolidating Company, this is because the Parent must also provide it own legal reports and also because you would need to make some adjusting entries to reflect the Consolidated Accounts.)

Thanks!

Alexander

The consolidated COA, would it work for multi currency multi company?
