I did an audit for them that took place over 12 weeks. They were easy. They required geoverify for that shop so I don't know if they still do, but geoverify is very easy to use.
If you have a smartphone you can download the geoverify app. It's necessary as far as I know for all of their shops. Reread the instructions. Otherwise, not hard shops at all.
I think this company has pretty easy shops. I love their BBQ restaurant shops - high reimbursement level, too. Gawd, and they're so pleasant & polite if you have to email them for anything.
