GnuCash

GnuCash is free, open-source desktop accounting software that applies professional double-entry bookkeeping principles to personal and small-business finance.

Built and maintained entirely by volunteers under the GNU GPL, GnuCash runs natively on Windows, macOS, and Linux, and can import data from QIF, OFX, and HBCI formats. It includes small-business features such as invoicing and accounts receivable/payable alongside financial reports and charts, making it a no-cost alternative to commercial desktop accounting software.
