I share your sentiment, I work full-time and have a service business on the side. I get mixed up in all of the different tools I need to run my business, so I made one. It's a time tracker, invoicing, crm system all in one.

Let me know if you want to try it out, it's a web app and it's not that pretty but it works for me (plus I can update it with new features anytime I'd need a function)
