Gnucash is an absolutely free small business and personal finance accounting system. Whether you are a small-business owner or an individual you can take advantage of this free double-entry accounting system. The program tracks all of your assets and liabilities using one convenient interface.
You can begin using the program with creating a database for your accounts. The information can also be imported from QIF files for all you Quicken users. All process is done through a step-by-step wizard.
Figuring out the program will take some of your time, so I encourage you to actually check out the tutorials that are supplied with the program. You can find them in the program's package. Double entry accounting is awesome as you won't lose a cent in your transactions, but it can also be a pain in the back. There is a reason people give four years in college just to learn principles of accounting, and then take exams for the rest of their lives to keep their accounting degree current.
You work with the program by either creating accounts (assets, expenses etc) and transactions within them. Check out the transaction screenshot to see what it looks like and what you can do within a transaction.
