GnuCash is a full-featured double entry accounting application. While initially designed to provide personal accounting features similar to the popular Quicken program, it has since grown to support accounting for small businesses and nonprofit entities. For personal accounting, the software includes features for budgeting, forecasting, automated scheduled transactions, bank and credit account statement reconciliation, and check printing, among others. For business or non-profit accounting, the software includes features for invoicing, accounts payable and receivable, and sales tax tables. New users can take advantage of "The Tutorial and Concepts Guide" (found by clicking "Documentation" in the Support menu on the left hand side of the page linked above), which provides a friendly introduction to the concepts of double-entry accounting and how to apply them with the software. On that same page, the "Help Manual" gives an overview of the software's user interface and operations. For Windows and macOS users, installers are available in the Download section of the page linked above. For Linux and BSD systems users, GnuCash is located in their package repositories.
