I said the "project economy". I didn't say: "I spent". In the end, I calculated the profit as if I didn't use my own tools, because that's what the reader of the case study wants to see.

The point of the whole post is to take one real case study. If you follow my steps, you have to pay for tools, so for the reader it's not important at all if I personally paid or not.

You don't get the point of the post at all. It's a case study on how I brought an idea to implementation and grew it to 7k revenue. What's the point of bringing up all those details? I didn't "fabricate" this case. This is a real case.

If I used other tools that aren't mine(i used godaddy and hosting..) would there be even the slightest difference for the key point of the article? If I start the article but saying: "I used my own tools...." would it make any difference to the main point of the article? for the case study?
