GnuCash

GnuCash provides double‑entry accounting for personal finances and small businesses. It records transactions across bank accounts, stocks, bonds, mutual funds, income and expense categories, maintaining balanced books and generating detailed reports and graphs. The software supports scheduled transactions, transaction matching, and import of financial data from QIF, OFX and HBCI formats, as well as basic financial calculations.

The program runs on GNU/Linux, BSD, Solaris, macOS (including Apple Silicon) and Windows, and is distributed under the GNU GPL. It is developed and maintained by volunteers, with documentation, translations and community support available through mailing lists, a wiki and IRC channels.

Designed to be as quick to use as a checkbook register while adhering to professional accounting principles, GnuCash offers features such as stock and bond account handling, small‑business accounting tools, and customizable reporting for users who need reliable, open‑source financial management.
