I created a multicompany structure in Odoo 14 because I need to know the different earnings and loss of each line of my business and generate different invoice templates from each line.
0-Main
1 - develop line
2 - content line
3 - marketing line
I wish to share the same bank account for child lines, and do bank reconciliation at the same time. How can achieve this? By default, I can't do it because Odoo need a bank account for each company.
The best way to achieve this is create analytics accounts to track each line, not multicompany structure. The invoice personalization for each kind of client could be done using modules.
