About a year and a half ago, Me and my brother posted https://github.com/metaware/angular-invoicing

We got ~70 upvotes and approx 500 stars on Github.

I've consistently seen traffic on our repos Github page since then, and have reasons to believe (Google Analytics metrics) that people use it on a regular basis. We have added a couple new features since our Show HN. It's free and always will be. :)
