Converting a client from 6 week packages to 3 months??


Hello!
I am a certified coach and currently have one paying client. She was renewed with me for the 3rd time with a 6 week package. Initially she wanted to lose 90 lbs and now down 30 lbs! I know she will probably want to continue with me and wonder if pitching her a 3 month package next is a good business idea.
Thanks!
