I find it useful to maintain an inventory of images, to keep track of how many pieces I have in hand / at exhibitions, and just for the sake of keeping all the image info in one place so I can find it easily when I have to make a slide list.

I use an Excel spreadsheet with the following headings along the top of the spreadsheet:

Inventory # (yy##) 
Sold (y/n) 
Title 
Series 
Date Started 
Date Completed 
Materials 
Size 
Pricing formula 
Retail Price 
Framing expenses 
Exhibits it has been shown in 
When/Where it sold 
Who purchased it 
Actual selling price 
Commission charged 
Other costs

Sharing this secret tool in case anyone finds it helpful!

Does anyone else have similar systems that make life easier?
