Do you use a special methodology (agile/scrum/timeblock) and need something to fit that or are you running your project ad-hoc?

If it's a case of the latter then I would advise to look into adopting a methodology and a systemized way of working before locking yourself into a tool.

In my experience there is a big correlation between using a methodology and having a solid foundation to build a solid business.
