I am thinking about a multi-company setup. This because the companies all need the same localisation parameters. They are all very small companies. I want to save cost and time for systems management and OPW. Every company has its own (part time) user. Companies are no sisters, parent or child companies. There are no shared contacts.
It is nice if users can communicate via OpenERP.
Is this possible? Does this complicate more than it solves? Is this a good idea?
