More Robust Reports

Would love to see more robust reports on the financials page such as being able to:

1. Download just the open PO's in order to see how much $$ is still outstanding to vendors (would be great if you could also filter by time period and by client)

2. A report showing sales tax for different periods of time (being able to custom the time frame)

3. A financial summary per client that shows the amount/sales of products purchased (the entire total and the markup total), the amount invoiced for time billing only, outstanding PO's, etc
