I would like to see a roll up report or visible breakdown of the projects and their various stages track work history. Similar to P&L but a breakdown of the projects and/or tasks (deliverables). I would like to see a rollup of total number of tasks completed by project by client YTD, or this month, last year, etc. This business intelligence would help me analyze who my best/worst clients are and help to determine if it's worth continuing to work with them in the future.
Maybe it's a simple report like the P&L? Maybe add a visual BI dashboard to Projects to show some pie charts or bar graphs. For my business I'd be able to see total number of gigs completed/confirmed/canceled at a glance. I'd be able to determine which client I've done the most work with. P&L only gives the $ side, but that doesn't always match up with your most consistent clients.
