Managing assets with a Google doc or a shared Excel spreadsheet is more common than you think. When your company is small, it can (sort of) work for a while, but as you grow, things get messy, fast. Snipe-IT lets your admins work together to track physical assets, software licenses, accessories and consumables -- all in one place.
Depreciation and asset reports are easy with one-click export to CSV and custom reporting capabilities. You can even give them permission to view and download reports within Snipe-IT without being able to edit assets. (And you can't beat the price tag - totally free to host it yourself, or choose the low-cost monthly/annual hosted solution!)
Snipe-IT makes asset management easy. It was built by people solving real-world IT and asset management problems, and a solid UX has always been a top priority. Straightforward design and bulk actions mean getting things done faster. What's the good of having software if it's so hard to use, no one bothers?
