Some time ago I found a program promoted by the insurance institute (who ever they are). It is an asset inventory program that allows you to set up different 'rooms'. You then can fill each room with the room contents. The room does not
have to be a physical room.
I've set up many rooms. I have all the physical rooms in the house and one for stuff in the yard. When it came to the shop, I made up a metal room, a welding room (same physical room as the metal room) a wood room and so on.
For each entry, you can put what you paid for the article, what the article is worth, purchase date, make, model, brand, place purchased, serial number, and description.
The next page lets you add photos of the device (as many as you want, I think), then there is a place for receipts (scanned in as a .jpg) and finally attachments (more .jpg files go there).
You don't have to fill out much of anything, or you can fill out as much as you want. I took a photo of each drawer in my tool boxes.
The program will tell you the total value of all the rooms, and the total value of each room. (Scary).
With the replacement cost and purchase price on the same page, I figure it shouldn't be too hard for someone to come up with a fair price when it comes time to dispose of the shop.
You can print the list by room, or the whole inventory.
Best of all, the program is free. It does take a while to put everything in, especially if you add quite a few photos to each thing you have.
The program is called WYO (What You Own) home inventory. The link is:

I guess I don't have to say I'm no stockholder in the company. If I was I probably would be annoyed that they are giving the program away. I've been using it for about 5 years. Now all I have to do is delete anything I give away or sell (not much) or just add the new things.
I'm sure I probably left things out. I opened a copy in front of me and I think I hit most of the high spots.
