Yes. Odoo supports multi-company (in a single database) and this comes with the ability to have several charts of accounts for each company as well as multiple reporting ledgers. Make sure you have the multi-company feature installed and activated in the General Settings. Make also sure it is activated on your user and that your user has access to the companies he is allowed to see. Then, go to the accounting settings where you will see a different set of settings for each company. Then, when you will go to the Accounting app to see your ledger, the wizard will ask you which company you want to see and depending on what you choose, you will see the ledger of corresponding Company.
