How Long Do You Keep a Piece of Paper

Our office owns radar trucks which we loan out. Well one is getting ready to leave the country and they have asked for the original bill of sale. On a truck bought in 2000. Really? Who keeps a bill of sale from 11 years ago? So I am diligently trying to track it down. Our records don't go back that far. The state only requires things to be held for seven years and if I kept every invoice for everything that every grant has ever bought I would be like one of those hoarders on tv with a narrow path to get anywhere. I certainly couldn't find ONE piece of paper.

So they may just have to go with the fact that yes we bought this truck in 2000 and believe that we paid for it.
