This will allow you to invite clients to a project where they can view a very simple client portal which shows associated Email, Forms (submitted/unsubmitted), Files, Calendar.
As a Hive App the Client portal could be configured at the workflow template level so forms etc are automatically applied to projects for external clients.
17Hats, Dubsado, SuiteDash - all do the job but combined with Hive this would be a gamechanger and a one stop shop. I have tested all of the platforms available and they all fall short on the project management side, so this would be a game changer.
We have a wedding stationery business so client portals are extremely helpful to keep everything organised and very simple on the customer facing side.
If it's not possible then an integration with would be great (albeit expensive for what they offer)
