I use Cake Child Care. It's online and it's so easy. $4.99 a month. The setup is a pain in the butt, but once it's all done, it's great. The parents just click on the picture of their child, and click "sign in". I can add early & late fees, so they are added automatically when parents check in. The parents can sign in and see their attendance at any time, how much they owe, any messages I have for the parents. I can also keep track of how many diaper changes, bottles, what we ate and how much their kid ate, naps, all kinds of things ... the $4.99 I pay each month makes up for itself in what I save in printer ink and paper.
But again, set up is kind of a pain. At least for me. I'm sure others could do it no problem.
