Add "Purchases" and "Used" to inventory reports
Add purchases and used columns to inventory report. I can see what I bought and I can see what I used and adjust pars as necessary or see exactly what has happened between counts.

You can actually generate a Usage report from the Reports page, which allows you to choose any beginning and ending date – not just the different between your most recent 2 inventory sessions. It shows your beginning, ending, purchases, and usage. It even gives you a place to input sales!
