We are able have one place for all of our customers, which is great! It's really easy as well - we've been using it since day 1 with no issues at this point in time (2 years).
I like that you can add new features without having someone else do so if needed or wanted by your users/customers; something more complex would require support from an external developer who has experience adding such functionality into their platform before they could implement them themselves internally within Focusscope itself.
