GnuCash has been translated into 21 languages and offers solid multi-currency capability, making the product an excellent option for small businesses and startups that conduct business globally. GnuCash was initially developed way back in 1997 as an alternative to Quicken, but newer releases of the application also include solid business features. GnuCash is not cloud-based software, so you'll have to download the application from their website.
As a result, the product is great for a sole proprietor, but would not be a good fit for businesses expecting to grow. GnuCash is a single-user system, so you won't be able to add any additional users to the application.
GnuCash is an accounting software that offers basic accounting functionality and is completely free, making it an excellent option for startups and small businesses with limited budgets, as well as for individuals interested in tracking their personal finances.
