Multiple Companies, Multiple Woocommerce stores

Hi all, I am quite new to the ERPNext and hoped it would be usable for our use case. Now I am starting to get quite unsure because I cannot seem to find a way to do the following;

We have multiple companies that have multiple sales channels. All run from 1 warehouse; however, all need to have a different source of “data” to be sent to the different sales channels. Is it possible to use 1 installation and create a loose inventory in the same warehouse for each company?

Multiple company setup is possible in erpnext…Create a parent company and under this parent company you can setup multiple child companies.
Hope this help
