I've been using http://snipeitapp.com/ Pretty easy to set up on a box in digital ocean, very low maintenance after I got it all set up and working, and if you'd rather not host it yourself you can pay them to do it. Has QR code/label printing capabilities, user management, less-detailed accessory tracking for keyboards and mice (i.e. there's like 20 keyboards over in accounting, and I have 5 available, but i know who has the other 12, and that 3 are broken). Can create reports of how much stuff costed, upload receipts to each asset, when warranty expires, all kinds of stuff. My only bitch about this was how you have to fill out the model before creating an asset under that model, which meant a lot of tedious tabbing back and forth while setting it up. Now that I have all the standard models of phones, laptops, and other hardware that we buy filled it, adding a new asset and assigning it to someone takes like a minute. The developer is super responsive to bugs and questions on her github page: http://github.com/snipe/snipe-...

The video of this was quite charming to watch. Little kid all excited and happy, plus the quote at the end. Simple, but it gave me chills. "This thing went to space."
