Does FlexBooks Work with Booker?
No. FlexBooks only works with Mindbody. Mindbody owns Booker, but Booker is a separate program, and its data isn't available through the Mindbody connection FlexBooks uses, so there is no way for FlexBooks to sync Booker to QuickBooks.
If you signed up for FlexBooks and your Booker site ID won't go through, this is why. Contact us and we'll cancel your account so you aren't charged.
