I did business software for 9 years and turned over nearly £2,000,000.
Wow! thats and average of £222k per year, if you were making an estimated 30% thats £66,600 per year. Thats a nice living!
I've been developing app's for the desktop and web for 9+ years and dont earn anything near that! Mind you, I am employed and not self employed. I guess that is what makes the difference.
I need a pay rise!
