What tools are you actually using to run your freelance business — and what drives you crazy about them?

Hey IH! I'm building a tool for freelancers and doing some research before my full launch.

Curious to know... what does your current stack look like? Project management, invoicing, client communication, file approvals, time tracking... how are you managing it all?

And more importantly: what's the most frustrating part? Is it the cost? Switching between too many apps? Clients not knowing how to use the tools you send them? Something else entirely?

Genuinely want to understand how freelancers are working day to day. Would really appreciate your honest take.
