Hello. I am involved with a computer-based charity where we take donation of old equipment, often recycle it, mostly rehabilitate it and make it available through grants and 'adoptions', and sell some items. What we're looking for is a LAMP package that can handle our records of donations of equipment, print receipts for donators, and also track our thrift store sales with receipts. Donators will want receipts of their donations for tax deduction purposes. We'll want to print reports of incoming items from time to time, say monthly and yearly. For the thrift store, we'll also need receipts for that, reports of cash, especially for reconciling cash drops, and also reports of items sold from time to time. I'm thinking this might be a single package, but it might be two. We don't want to track our shop inventory with either of these programs -- that's another program/project. We just need to know what was donated and what was sold. It must be open source, and ideally we'd like it to run on LAMP -- Linux, Apache, MySQL, PHP, but we will consider other open-source platforms.
