Used to work for a place with beancounter issues. Any time we ran new cabling, if the install labor went over some variable limit, it needed an asset tag. On the cable. So, we pasted this on an IDF rack, which over time became filled with such labels.
One year, we finally excessed that rack, and all those installs finally fell off the books.
Conference rooms were fun like this too, multiple bits of gear that were too low value for their own tags, got lumped into a Project, plus labor, and we received another asset label, which was applied to a bit of relatively permanent furniture. Years after the equipment was slowly replaced, we still had those labels to inventory. Finally, we got new furniture, problem solved. The furniture itself, BTW, was never part of our inventory.
When I took over that job, I inherited a long list of problem inventory that was missing. Before the next audit, I submitted several batches of paperwork to finance marking said items as having been shipped to various companies as demo equipment. These company names were pulled from various sources, usually companies that had been bought out by larger companies, filed bankruptcy, etc. When audit time came, I pointed out that the gear was on loan. After a cycle or two, I informed Finance that the companies were gone, and so was our kit, and they were welcome to chase after it if they liked or write it off.
Oh, and for fake emails when needed, I usually use bob@bobber.bob. Most web forms take it without issue.
