I like that it's easy enough so we can use without having someone with advanced software training, but also has features that are intuitively simple even if they're more complex in reality! The interface could be improved by adding some sort of "click here" button next to each field instead of requiring me to click through every single option one at time before hitting submit/enter - this makes things much slower than necessary when there should really only need to be 1 keystroke per entry required from us users anyway. We've been able solve many issues related to inventory management using profitkey including tracking production orders against stock levels & quantities received vs expected dates / times.
