How we chose these QuickBooks alternatives

We looked for finance software that overlaps with QuickBooks' core: invoicing, expenses, bookkeeping, and financial reporting. We verified each project's license, recent activity, stars, and self-hosting in its GitHub repository. QuickBooks is a business accounting suite, but several alternatives here are personal finance or investment tools, so we say which ones are real accounting systems. We also flag licenses that restrict commercial use. See our methodology for the full criteria.

Important: several of these are not standard open source

Akaunting uses the Business Source License 1.1 and Invoice Ninja uses the Elastic License 2.0, so both are source available. Akaunting's free grant covers up to two users, one company, and 1,000 invoices, and bans white-labeling and offering it as an accounting service. Monetr uses FSL-1.1-MIT, a Fair Source license. Check each license before using them in a business.

Business accounting vs personal finance

Akaunting, Invoice Ninja, Crater, Frappe Books, and Bigcapital handle invoices, expenses, and reports for businesses. Wealthfolio tracks investments, and Monetr and YAFFA are personal budgeting and finance apps, so they do not replace QuickBooks for company bookkeeping.

License details

Frappe Books, Bigcapital, Wealthfolio, and Crater are AGPL-3.0, and YAFFA is MIT. AGPL requires sharing modifications if you offer the software to others over a network.

Desktop vs web apps

Frappe Books and Wealthfolio are local desktop apps that store data on your machine. Akaunting, Invoice Ninja, Bigcapital, Monetr, and YAFFA are web applications you host, and Invoice Ninja also has desktop and mobile apps.

Maintenance status

Crater has had no commits since August 2024, so avoid it for new deployments. The other projects, including Invoice Ninja, Akaunting, Wealthfolio, Frappe Books, and Bigcapital, were updated within weeks of this update.

Why look for a QuickBooks alternative?

QuickBooks is a proprietary subscription accounting platform with per-plan pricing and your financial data stored on Intuit's servers. Open-source and source-available alternatives let you self-host or keep data on your own machine, avoid subscriptions, and customize invoicing, at the cost of fewer integrations such as payroll, bank feeds, and tax filing.
