Wide Open Wallet: 50 Awesome Open Source Financial Tools
From the URL...
"One of the great things about open source is that you know the software you’re using is made by real people, who understand real needs. In financial software, we see a great application of this "real people" effect, offering high levels of customization and ease of use. In this software collection, you’ll find tools that were made with you in mind, and are often completely free to boot. With these finance management packages, you can stay on top of all of your accounts in one convenient place."
(Sounds like there are a few tools that NPs might use)
