You can invite anyone you trust to be a Business Collaborator in Wave. But what if your collaborator already has a Wave account? Here's how that works.
Let's say you're a Wave account holder, and your business is called Nautilus Hosting. Raj is also a Wave account holder, managing a business called Honest Abe Renovations.
You've asked Raj to collaborate on Nautilus Hosting. When he accepts the invitation to collaborate, he will see both Nautilus Hosting and Honest Abe Renovations in the lefthand tool bar.
Raj, and any other collaborators you add, can now switch between businesses without having to log in and out of different Wave accounts.
