Why look for Fusebase alternatives?

Fusebase is a flexible project management tool with many other valuable features. However, a good portion of Fusebase users are looking for another platform. Here's why.

The secure client portal, the powerful project management tool, team collaboration features, workflow automation... They're all fine, but the average user does not need all of them in one place. At a starting place of $38 per month, Fusebase is not restrictively expensive. However, what if you don't need the client communication features and all you're after is task management or the knowledge base?

Here's how one user put it:

"It has a lot of features I don't need, but I like that it's still simple and easy to use. Like, I can just not use some client portal functionality and not fall back in the user experience."

And here is one more account:

"Working on small projects, I don't need so wide functionality the tool offers. But ignoring what I don't use, the core features I leverage daily have been great."

And that's pretty much it. Fusebase has solid automation features and collaboration tools, but in reality, it just might be too much for someone looking for a simple knowledge management or client collaboration tool.
