It's user friendly--it does what it says! There are no problems that I can think off at this time as far as using Kinder Track or being able to integrate into other systems like Paychex for payroll processing etc. The only thing we do not have yet implemented is integration w/ HRISs such as ADP Connector (which would be great) but so far everything has been fine without having to implement any additional software to use the program! The ability to pull up all my child's information at once. I can see if they have been sick or had an accident. It's also great for when we are booking a new daycare! The only thing that I dislike about this program is that it sometimes takes a while to get paid. Sometimes it could take weeks before you receive your payment, but as long as you follow up with them, they will usually pay quickly. We use this system to keep track of our child's attendance and health.
