I like that you can do everything from your phone, including writing tickets to adding new permits! It is very easy but not too user friendly at first glance (which was what we were looking into). We are solving our parking enforcement issues with this system so it has been great in terms of efficiency as well. The only thing about colipark parkingsystems i dislike would be how long its takes sometimes before they get back after an issue arises or ticketing someone who parked illegally/illegally etc.. This helps us solve all those problems by using mobile solutions!!
