How many companies are you connect with, using their apps? How may companies have a profile of you? How many time you spend understanding ther apps, finding your own data en update them? How often you get frustrated because they all do it in their own way?
Connect these companies and your suppliers to the way YOU want to work. Let them mail you and create settings for what you want to see, and what you don’t want to see.
Have many contacts with a supplier? Create a domain with their contacts and communicate when and how you want it. Another supplier? Switch off the domain for the old one.
