I run a payroll site (http://smallpayroll.ca http://smallpayroll.ca). I could see some small businesses that rely on shift work like this, especially if it could push hours into their payroll software. There aren't enough features for a call centre to use it, but I could see convenience stores and restaurants loving it. What's the storage space used for? I looked at the pricing page and the storage per level really stood out. 1GB is a lot, what am I storing? How do I know I have enough storage?
