I've been looking at software to help us deal with managing these clubs and the payments that come with it. We're currently with ParentMail and don't like the way they have proposed. So looking to purchase another system Tucasi seem to appear a lot when I research on this topic. Has anyone used Tucasi Extended Day module? How much does it cost? Can we purchase it standalone (without moving from ParentMail)? What's good and bad about it? Any other recommendations?
