Open-source Sage Intacct alternatives

Odoo is a bundle of browser-based, open-source business applications. Apps cover sales (CRM and eCommerce), a website builder, inventory and manufacturing, projects, invoicing and accounting, point of sale, human resources and marketing. It is written in Python, and GitHub lists the license as 'Other', so check the repository for the exact terms.

Each app can be used as a stand-alone application, but they are designed to work together, so installing several apps gives you a full-featured ERP system. This lets a business start with a single function, such as sales or invoicing, and add modules as its needs grow without changing platforms.

The README points to setup instructions for a standard installation, an eLearning course and a business game called Scale-up for learning the software, and developer tutorials for extending it. Odoo can be run on your own infrastructure, and the vendor's website offers commercial services. It suits small and mid-sized companies looking for an integrated business suite.

This entry points to ERPNext, the open-source enterprise resource planning system developed in the frappe/erpnext repository on top of the Frappe framework. It aims to replace the patchwork of separate programs a business often uses for invoices, stock, personnel and daily operations with a single integrated product.

Its modules include accounting for cash flow, transactions and financial reports; order management for inventory levels, replenishment, sales orders, customers, suppliers and shipments; manufacturing for production cycles, material consumption, capacity planning and subcontracting; asset management from purchase to disposal; and project delivery. Topics also list HR, CRM, procurement, retail, distribution, healthcare and support functions. It is written in Python, and a live demo is available.

ERPNext is GPL-3.0 licensed and can be self-hosted. The Frappe team also offers managed hosting, which suits companies that want the software without running servers. It is aimed at small and mid-size organizations that want an alternative to proprietary ERP suites.

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.

Dolibarr is an open-source ERP and CRM package for managing an organization's activity: contacts, suppliers, quotes, invoices, orders, stock, agenda, accounting, human resources, document management and manufacturing. It targets small, medium and large companies, foundations and freelancers.

It is a PHP web application with JavaScript enhancements, released under the GPL, version 3 or later, and can be used as a standalone application or as a web app reached over the internet or a LAN. Installation options include DoliWamp for Windows, DoliDeb for Debian and Ubuntu, DoliRpm for Red Hat family distributions, a Docker image, or a manual setup on Apache or Nginx with MariaDB, MySQL or PostgreSQL.

The project has a large community with free forums, and preferred partners offer commercial support if needed. Because it is modular, organizations switch on only the features they need. It suits small businesses and associations that want an integrated business suite they can host themselves.

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.

Frappe Docker is the official container setup for Frappe applications. It provides Docker images, Compose configurations, and documentation for running ERPNext, Frappe CRM, Helpdesk, HRMS, and your own custom Frappe apps in containers. The repository is released under the MIT license.

You can use it to start from a quick demo setup, adopt production-ready images and Compose files, build custom app images that bundle your own code, and operate Frappe in production. The README says the repository structure covers documentation for deployment and operational workflows, along with override files that offer opinionated configuration choices.

It is aimed at system administrators and developers who deploy business software based on the Frappe framework and want a repeatable, containerized setup instead of a manual bench installation. Topics reference ERP, CRM, HR, and self-hosted business software, so it is relevant for small and mid-sized companies running ERPNext on their own servers.

metasfresh is a responsive, free, open-source ERP system aimed at companies in industry and trade. It covers wide and detailed business functionality, with topics listing manufacturing, accounting, and CRM, and it focuses on fast, easy-to-use enterprise software with a good user experience. The input does not state a license.

The architecture has three tiers: a Java back end built on Spring Boot with PostgreSQL, a REST API, and a web front end developed with HTML5, ReactJS, and Redux. A stable release is published every Friday, with a short break at the end of the year, and it can be installed through Docker or an Ubuntu installer package.

The project is aimed at mid-sized businesses that need scalability and flexibility and prefer to run their ERP on their own infrastructure. It suits companies looking for an open-source alternative to commercial ERP suites, especially those with in-house IT or a service partner able to implement and maintain it.

iDempiere is an open-source business suite that combines enterprise resource planning, customer relationship management and supply chain management, with manufacturing and point-of-sale topics listed in its description. It is developed by a global community of SMEs, implementors and end users.

Technically it is built on Java with a ZK web UI, with PostgreSQL or Oracle as the database foundation, and a modular architecture whose plugin system is powered by OSGi. Its business logic evolved from ADempiere and Compiere. The project offers live cloud test sites so you can try it without installing, an official installation guide for local setups, and community channels including a Google Groups forum and a Mattermost chat.

Bugs and feature requests are first discussed in the forums and then filed in a JIRA tracker, and continuous integration runs on Jenkins. iDempiere's repository license is listed as Other, so check the project's terms, and you run it on your own infrastructure.
