Amsys is an Eve Online Buyback program for any size of organization, from Alliance to Corporation or even an aspiring merchant. Amsys allows members to sell game items to you for a market price of your choice, minus your cut of course!
Allow Alliance/Corporation Members or Public users to sell materials to you.
System provides Market details from Eve Central, and prices items based on stats you choose.
Simple documentation/wiki'ish system included for Alliance/Corp bullitens or information.
Amsys started out as a Google Spreadsheet in my corp, then evolved to a CakePHP application that allowed Ore to be purchased. Amsys then evolved in to a full fledge system that can buyback any item in game and has slowly added other abilities.
* - Items that can be bought and sold on the in game Eve Market
As stated, this system is in active development, I will try to keep this list up to date as we develop
