For a period spanning August 2016 to June 2017 I put up what I called an income report post showing how much product revenue I had earned that month. My source of revenue during that time was a website called AngularOnRails.com which I eventually decided to give up on, partly because I didn’t actually like the stuff I was teaching.

Then there was a period where I flailed around from idea to idea and didn’t earn any meaningful product revenue from anything. Then in January 2018 I joined 30×500 and got on the right track toward starting a new product business that would actually be successful.

January 2018 to February 2019 was basically a long incubation period that led to my March 2019 launch of Rails Testing for Beginners, an ebook that hopefully has a self-explanatory title.

During my launch I earned $988. During the whole month of March 2019 I earned $1037, making it my best product revenue month since October 2016 and my third-best product revenue month ever. I’m very happy now to have a reason to continue posting these income reports, although now I’m going to call them “product revenue reports” because I think that’s a more accurate way of putting it.

Here’s every meaningful month of product revenue I’ve had since August 2016.
