My suggestions are:
1. There should be an icon or link for calculator on the screen which will prove handy while entring transactions.
2. While adding new entries every time one need to click on Add new button again and again. It becomes troublesome for multiple enteries. So, Save & New enteries option should be there.
3. while searching enteries, it should be on the fly ajax based.
4. In the reports section, While viewing enteries for example expense report the entries should have link where one can check what that enteires about or the option to view it.
5. An android app is what that makes this software a much needed kick start
All together its an amazing software.
thanks and regards
