The best thing about this software is that it allows me not just to enter my data into one system, but also analyze where I have made errors in order to improve future entries! There's nothing really - we've been able to get down our actual usage by tracking how many units are used per month for each product line within our department (or even individual employees).
We haven't found anything wrong with this program so far; however, there has never been an issue since beginning use over 2 years ago. It does what its supposed to do without too much hassle or confusion regarding functionality. Keeps track of all inventory items/cost centers at any given time as well as reporting overall spending via monthly statements.
