How to allow 2 domains to access a unified database
I run an agency network with 4 companies, and each having its own domain. We are subscribed to the Pro Plan separately for each of the companies under their own domains.
We now want to have a unified database to allow the users from all 4 companies to share the same database as we share the same clients, and have cross functional processes and currently we have to duplicate any contact, organization, project or opportunity in Insightly across the different companies.
Is it possible for us to do that and how?
