They only scan and archive contracts, not the proposals, the correspondence, the network designs, orders, etc...
Because I was a packrat and never deleted anything, I had evidence which caused two large ISP's that disputed financial responsibilty in a buyout to have to pay. The ISP I had designed a network for had been bought by another larger ISP. The company that was bought refused to pay, saying that the new company had agreed to pay off their contract, the new ISP claimed they had made no such agreement. My company was ready to settle for a fraction of what was owed to us. I was asked by my company to just attend the court hearing, but when I told them I had all of the original correspondance between the owners of the two companies, and the attornies for my company saw what I had, they decided to hold the new ISP 100% responsible and the ISP's attornies had to agree and we got the full amount, it was a multi-million dollar contract. I got a nice thank you letter from my company, but no money.
