I've created a fairly successful iOS app that sells for $9.99 in the App store. It brings in about 75k per year and has been featured twice by Apple since launch. In the past few months, three companies have contacted me looking to build and sell their own apps using my source code.
The company I'm currently speaking with is Forbes 500. I feel a little out of my league with this licensing/relicensing thing. After some research, I've come up with the following plan.
- Up-front licensing fee, probably in the mid 5-figures.
- 20% annual maintenance fee.
- Relicensing fee. They want to sell (or give away) this new app in the App store. Should I ask for per-user royalties? What if the app is free?
- Finally, an hourly custom development fee for changes and new features.
Outside of having a good lawyer look at this, do you think I have covered my bases here? Am I missing anything, or am I asking too much (or too little?) I'd greatly appreciate some expert feedback!
