Your organisation's own environment: own members, roles and branding — with its own web address and installable app if you want.
A workspace is the environment your organisation works in. Everything in it is yours: the members, the roles, the modules, the branding. Other organisations see none of it.
A workspace can get its own web address and be installed as an app on the phone, with your name and logo — for the technician on site, Oanax is simply 'the work app'.
Almost every feature is a switch per workspace. What you do not turn on does not exist for your people.
