What it is

IDURAR ERP CRM is a free, open-source enterprise resource planning and customer relationship management application built on the MERN stack. The backend runs on Node.js with Express.js and MongoDB, while the frontend is written in React.js and uses the Ant Design component framework together with Redux for state management. The project is released under the GNU Affero General Public License v3.0, and the repository is written in JavaScript. It carries the accounting, ERP, CRM, invoicing, and e-commerce topics on its registry entry, and the README describes it as open "fair-code" source software.

The concrete problem it addresses is the cost and lock-in of commercial ERP and CRM suites for small businesses and self-hosting teams. Rather than paying for per-seat licensing, an organisation can run its own instance to handle invoices, quotes, customer records, and payments inside one application. The README explicitly permits free use for both personal and commercial purposes, so a business can deploy it without a licence fee. A hosted, self-hosted enterprise version is offered at cloud.idurarapp.com for users who do not want to run the stack themselves.

Key capabilities

• Invoice management for creating and tracking customer invoices.
• Quote management for issuing and following up on quotations.
• Payment management for recording payments against invoices and quotes.
• Customer management for maintaining client records alongside billing activity.
• React.js frontend built with the Ant Design (AntD) framework and Redux.
• Node.js, Express.js, and MongoDB backend forming the MERN application stack.
• Accounting features positioned within the wider ERP scope described in the README, which also names inventory and HR.

Who uses it and how

• Small businesses that want invoicing, quoting, and customer records in one self-hosted tool rather than separate subscriptions.
• Accounting and finance teams that need to generate invoices and attach payments to them.
• Agencies and service firms that issue quotes and convert them into customer billing records.
• Commercial users, since the README states the software may be used free of charge for personal or commercial purposes.
• Teams that prefer the MERN stack, because the frontend and backend are Node.js, Express.js, React.js, and MongoDB throughout.

Getting started

The README's getting-started section is a nine-step sequence: clone the repository, create a MongoDB account and database cluster, edit the environment file, update the MongoDB URI, install backend dependencies, run the setup script, start the backend server, install frontend dependencies, and start the frontend server.
