Do you use multiple tools for freelancing, or prefer everything in one place?

Some freelancers love having a separate tool for each thing. Others just want one platform that keeps clients, projects, tasks, and payments together.

I’m building Ativium Freelancing, and I’m trying to understand which direction makes more sense for real users — simple & focused or all-in-one.

How do you feel about it?
Does “all-in-one” help or overwhelm?
