Open-Source QuickBooks Alternatives (2027): 9 Free Accounting Tools to Replace QuickBooks Online, From GnuCash and Bigcapital to ERPNext and Dolibarr

Open-Source QuickBooks Alternatives: Free Accounting Software You Can Own, Host and Move Your Books Into

QuickBooks Online is the default bookkeeping tool for many small businesses, but it is a subscription you rent: prices rise, user limits decide which plan you need, and your books live on Intuit's servers. Open-source accounting software flips that. You can download it, run it on your own computer or server, read the code and keep your data in a format you control. We checked every tool below on its official website and code repository on 2 November 2026: the licence, the latest release and which QuickBooks jobs it can really take over. Several tools from the old version of this list turned out not to be open source, or no longer maintained; they are listed separately near the end.
Quick answer: for one person keeping the books on a laptop, use GnuCash. For the closest feel to QuickBooks Online in a browser, with invoices, bank feeds and reports, self-host Bigcapital. If you also need inventory, purchasing, HR or manufacturing, choose ERPNext; for something lighter on the same base, Frappe Books. Dolibarr, FrontAccounting and LedgerSMB are long-running, easy-to-host web options. Watch out for two popular names: Akaunting and Manager.io are free to use but are not open source.

What QuickBooks Online Costs in 2027

On the US QuickBooks pricing page (US dollars, default monthly view, checked 2 November 2026), Intuit now lists a Free plan at $0 a month for 1 user, with no accountant access, 2 invoices a month and 1 connected bank. Paid plans are listed at $38 a month for Simple Start (1 user), $85 for Essentials (3 users), $140 for Plus (5 users) and $340 for Advanced (25 users), each shown with 50% off for the first 3 months, no annual contract and a 30-day free trial. The page did not load from our location in Europe, so we read the US version; prices in other countries differ. That is the bar: an open-source tool costs nothing in licence fees, but you pay for hosting, backups, updates and your own time.

Simple Bookkeeping for Founders and Small Teams

1. GnuCash: free double-entry books on your own computer

GnuCash is personal and small-business accounting software, licensed under the GNU GPL and developed entirely by volunteers. Version 5.17 came out on 27 September 2026, for Windows, macOS and Linux. It keeps proper double-entry books and, according to its features page, covers customer and vendor tracking, jobs, invoicing and bill payment, tax and billing terms, budgets and multiple currencies; payroll is possible only by hand, through receivable and payable accounts. For a QuickBooks user the catch is that GnuCash is a desktop app: one file on one computer, without the automatic bank feeds QuickBooks users are used to for most banks. Bank statements come in as OFX or QIF files, and its transaction matching spots duplicates during the import.

2. Bigcapital: the closest open-source match to QuickBooks Online

Bigcapital describes itself as AI-native open-source core accounting infrastructure, and it is the project on this list that looks most like QuickBooks Online: a web app with sales and purchase invoices, expenses, inventory, multi-currency, receivables and payables, accrual and cash accounting, tax, bank feed syncing with reconciliation, and a balance sheet, profit and loss and cash flow report. It is published under the AGPLv3, and its FAQ says self-hosting is free under that licence. The Bigcapital repository shipped v0.25.45 on 23 October 2026. You run it with Docker; automatic bank feeds on a self-hosted copy need your own Plaid account, which the documentation explains how to set up. Its API also lets developers use it as headless accounting inside their own product.

Open-Source ERPs With Strong Accounting

3. ERPNext: accounting plus the rest of the business

ERPNext calls itself the world's best free and open-source ERP, and its code is GPLv3. Version 16 is current: v16.53.0 came out on 28 October 2026. Its accounting covers several companies and currencies, the general ledger, payables and receivables, financial statements, fixed assets and tax, with stock, buying, selling, projects, HR and manufacturing in the same system. One point for anyone leaving QuickBooks: the built-in QuickBooks Migrator is gone. The ERPNext documentation says it was removed on 17 January 2025, and that a migration now means exporting your data from QuickBooks, cleaning it and loading it with the Data Import tool, the Chart of Accounts Importer, the Opening Invoice Creation Tool and opening journal entries.

4. Frappe Books: simple accounting, now in the browser

Frappe Books is the lighter accounting app from the makers of ERPNext. It used to be a desktop app; on 2 October 2026 that desktop version reached end of life and its repository was archived. The new Frappe Books repository (AGPLv3, v16.1.0 on 30 October 2026) runs on the Frappe Framework on your own server, so your team signs in from a browser on a computer or phone. It covers a double-entry ledger, profit and loss, balance sheet and trial balance, quotations, invoices, payments, inventory and a point of sale, with India GST reports and Swiss fields. If you installed the old desktop app, plan a move: the website says it is no longer supported.

5. Odoo Community: free invoicing, but full accounting is paid

Odoo is a business suite whose Community edition is published under the LGPLv3. Be clear about what that edition includes: in the Community code, the finance app is Invoicing, which creates and sends invoices, records payments and handles vendor bills. Odoo's documentation says its full Accounting app adds standard financial reports, bank reconciliation, budgets and asset management, and that app is part of the paid Enterprise edition, not the open-source code. Odoo Community therefore suits a startup that wants invoicing linked to its CRM, sales and inventory and leaves the books to an outside accountant.

6. Dolibarr: modular ERP and CRM with double-entry accounting

Dolibarr is an open-source ERP and CRM for small and large companies, freelancers and associations, released under the GPLv3. Version 24.0.2 is the latest on its homepage. You switch on only the modules you need; for QuickBooks users the relevant ones are billing and payments, bank reconciliation and double-entry accounting, next to quotes, orders, stock and a CRM. You can install it on your own server or virtual machine, or use a SaaS offer if you would rather not install anything.

Classic Self-Hosted Accounting Systems

7. FrontAccounting: web-based accounting for small companies

FrontAccounting is a free, GPL-licensed web accounting system run as a non-profit community project. Version 2.4.20 came out on 28 April 2026. It covers purchasing and supplier invoices, sales orders and customer invoices, receivables and payables, inventory, manufacturing, fixed assets and a general ledger with budgets and up to two dimensions for cost tracking, in several languages, currencies and companies. It is a good fit if you want a no-frills accounting system on a small web server.

8. LedgerSMB: accounting and ERP for small and mid-size businesses

LedgerSMB provides open-source accounting with invoices, orders and quotations, receivables and payables, a general ledger, inventory and fixed asset depreciation, in 45 languages, under the GPL. Its current stable series, 1.13, was released on 4 October 2025 and has community support until 4 October 2027; the latest patch we saw is 1.13.8 from 11 September 2026. The project began in 2006 as a fork of SQL-Ledger and puts correctness and performance first, which suits a business with a lot of transactions.

9. Apache OFBiz: an ERP framework for developers

Apache OFBiz is an Apache 2.0-licensed suite of business applications, including accounting, that developers build on. Release 24.09.07 came out in June 2026; the 24.09 series has been feature-frozen since September 2024 and receives only bug fixes. It is not a QuickBooks replacement you install on Friday and use on Monday, but it is a solid base if you have developers and need custom accounting inside a larger system.

Not Open Source, Changed or No Longer Maintained

The 2025 version of this article listed ten tools. Five of them no longer belong on an open-source list:
  • Akaunting: free to download, but its licence file is the Business Source License 1.1, not an open-source licence. Production use is not allowed with more than 2 users, more than one company or more than 1,000 invoices, and you may not white-label it or offer it as an accounting service. Each version only becomes GPLv3 four years after it is published. It is still developed (3.3.0 came out on 27 October 2026).
  • Manager.io: the Desktop edition is free for one user, and its source code is now on GitHub, but the README says plainly that Manager is source-available, not open source. It uses the Functional Source License, and each version becomes Apache 2.0 two years after release.
  • TurboCASH: the website still calls it open-source double-entry accounting and offers a free version and a $60-a-year subscription, but the site footer says 2022. Its SourceForge project lists the GPLv2 and a TurboCASH 5.4 release candidate uploaded on 29 September 2026 as a Windows installer; we could not confirm current source code, so it is not on the main list.
  • OpenAccounting: the hosted service is free only for single-user personal use, and its open-source server code on GitHub has not been updated since September 2023.
  • SQL-Ledger: the latest download is still version 3.2.12 from 2 January 2023; a 3.2.13 bug-fix release announced for 1 February 2025 never appeared. LedgerSMB, its maintained fork, is the better choice.

Which Open-Source QuickBooks Alternative Should You Choose?

  • You are a solo founder doing your own books: GnuCash.
  • You want QuickBooks Online's look and bank feeds, self-hosted: Bigcapital.
  • You sell products and need stock, purchasing and accounting together: ERPNext, or Frappe Books for a smaller setup.
  • You mainly send invoices and have an outside accountant: Odoo Community's Invoicing app.
  • You want CRM, quotes and accounting in one light system: Dolibarr.
  • You want simple, no-frills accounting on a small web server: FrontAccounting.
  • You have many transactions and care about correctness: LedgerSMB.
  • You have developers and need custom accounting: Apache OFBiz.
  • You do not want to run a server at all: stay on a hosted plan; QuickBooks Free or the options in our free Zoho Books alternatives are simpler.

How Founders Move Their Books Off QuickBooks

Switch at the start of a month or quarter, export your chart of accounts, customers, suppliers, open invoices and a trial balance from QuickBooks, and enter the balances as opening entries in the new tool. Keep QuickBooks read-only until your accountant has checked the first month. If you also want to compare other accounting suites, our open-source Sage alternatives cover Tryton, iDempiere and plain-text accounting, and our free Zoho Books alternatives list hosted free plans such as Zoho Invoice and Wave. Bank reconciliation is where most switches go wrong, so read our guide to the best reconciliation software before you start, and see how to set up estimates and invoices for a service business.
Then connect the rest of the back office: open-source Expensify alternatives for expense claims, open-source Stripe alternatives for payments, and open-source Zapier alternatives to move data between them. Your CRM can be open source too: see our open-source Salesforce Einstein alternatives and open-source Apollo.io alternatives, and keep procedures and month-end checklists in one of the open-source Notion alternatives.
