Ask HN: Freelance Management Services/Apps

We use https://tmetric.com/. Simple to use and gets the job done.

I have to second this. Toggl is fantastic not just for freelance time management, but for managing time spent on any project. It has a lot of features that you'd just expect to be there, like when the browser icon changes whether you're on the clock or off the clock, or how you can just click 'play' on a previously logged task to resume the timer for that task.

We use Albert https://www.getalbert.com/ (UK-only). Very easy for invoicing.

https://books.zoho.com is international and has been wonderful for my project billing. I've been using it for ~2 years as a freelancer and have no complaints. I don't have any business or accounting education and I credit the design of the UI with helping me learn basic accounting principles.
