First paying SaaS customer

Businesses were begining to use the service and needed more advanced features and a way to remove the ads from their quizzes. So I built a version that allowed customers to pay a monthly fee to keep their quiz ad-free.

6 months after launching the SaaS version I got an email from Stripe saying that I had earned $30. Still remember the great feeling when someone bought my service without even talking to me beforehand.
