Open-source Sage Accounting alternatives

Akaunting is an accounting application delivered over the web and aimed at small businesses and freelancers. It is built with Laravel, Vue, Tailwind and a RESTful API, and its modular structure supports an app store where users and developers can extend the core product with additional features.

The topics show its scope: invoicing, billing, payments, expenses, budgets, bookkeeping and balances, with further hints at payroll, CRM and ERP use. It installs with Composer and npm, needs PHP 8.1 or higher and Node.js 18 or 20, and works with MariaDB, MySQL, PostgreSQL or SQLite behind Apache, Nginx or IIS. An optional command seeds sample data for trying it.

The project offers a forum for support, documentation, a developer portal and the app store. The repository lists the license as Other, so check the licence file for terms. Because it is PHP and Laravel based, it suits teams that want to run and customize their own accounting system on a standard web hosting stack.

GnuCash is financial accounting software for individuals and small businesses, freely licensed under the GNU GPL. It lets you track bank accounts, stocks, income and expenses, and it is built on professional accounting principles so that books balance and reports are accurate.

The interface is meant to be as quick and intuitive as a checkbook register while still being flexible. It is double-entry accounting software, and it is available for GNU/Linux, BSD, Solaris, macOS and Microsoft Windows, with a Flatpak build on Flathub. The website lists documentation, an FAQ, mailing lists and chat, and the interface is available in many languages.

GnuCash is developed, maintained, documented and translated entirely by volunteers, and the project invites help with development, documentation and translation. It is written in C, and older releases remain available for Windows 7, older macOS versions and PowerPC Macs.

Bigcapital is accounting and inventory software for small and medium businesses. It aims to keep business finances in one place and automate accounting processes, producing financial statements and reports to support decisions. The project is positioned as an independent alternative to QuickBooks, Xero and Wave.

Repository topics cover double-entry accounting, invoicing, bills, expenses, payments and inventory management. The README describes multiple ways to get started: use Bigcapital Cloud, or self-host the open-source edition on your own servers with Docker. It is written in TypeScript and gives teams the ability to inspect and adapt the code.

Bigcapital is available under the AGPL license for self-hosting, while the vendor runs the managed cloud version. It suits freelancers, small companies and bookkeepers who want accounting control without per-user subscriptions to a closed platform.

IDURAR is an open-source ERP and CRM application that covers invoicing, quotes, payments and customer management, with accounting-oriented features. It is built on the MERN stack of MongoDB, Express.js, React and Node.js, with Ant Design for the interface and Redux for state.

The README lists invoice management, payment management, quote management and customer management as its main features and links to a hosted enterprise cloud version. It states clearly that you may use IDURAR for free for personal or commercial purposes. Repository topics include accounting, e-commerce and CRM, and it is written in JavaScript.

GitHub lists the license as AGPL-3.0, so check its obligations if you modify and offer it over a network. IDURAR is deployed on your own server, or you can use the vendor's cloud. It suits freelancers and small businesses that want a basic invoicing and customer system they can customize in JavaScript.

InvoicePlane is a self-hosted web application for managing invoices, clients, and payments. It is written in PHP on the CodeIgniter framework and is aimed at freelancers and small businesses that want to run their own billing system instead of paying for a subscription invoicing service.

It covers invoice and quote creation and sending, client records with contact details and transaction history, a product catalog and tasks that can be added to invoices, payment tracking with reminders, and integration with several payment gateways. Templates, themes, and settings can be customized to match a brand, and reports summarize financial performance.

The project publishes release notes, a changelog, and upgrade instructions, and it asks administrators to read the changelog before updating because some releases are security fixes. A Docker compose file is available for local development and testing only. Check the repository for the exact license terms, which the input lists only as other.
