$1000/Month App Made For His Girlfriend

  • Tom Redman

  • Founder of Lessons Invoicing
  • $1000 monthly revenue

A redditor writes that he created this simple invoicing app for his girlfriend’s business.

Apparently his girlfriend is a skating coach ⛸

She showed the app to other skating coaches and word spread “all the way down to Texas and Alabama.”

It’s a freemium app, now pulling in $1000 per month 🤑

How the app came about…

I did very little market research, and instead focused on exactly what my girlfriend needed to invoice her students. She had tried a few things, QuickBooks, spreadsheets, paper, etc – nothing did this specific job very well. Typically, they were massively overkill for her needs. She wanted to input new lessons in seconds, and have an invoice auto-generate. That’s it – so that’s what I built!

Might be worth chatting with people close to you about their experience with software they use regularly. Maybe you’ll find a similar opportunity.
