Self-host an invoicing and CRM app for a small business as an alternative to QuickBooks or Salesforce.
Use the nine-step INSTALLATION-INSTRUCTIONS flow to wire up a MongoDB cluster, backend, and React frontend.
Customise the Ant Design React UI on top of the existing Redux state to fit a specific company's invoice workflow.
Study a MERN stack ERP layout as a template for a similar self-hosted internal tool.
Needs a MongoDB cluster (Atlas or local), env file with the connection string, plus separate backend and frontend dev servers.
This repository is a personal copy of IDURAR, an open-source ERP and CRM application aimed at small businesses that want to manage invoices, quotes, payments, and customer records without paying for a hosted product like QuickBooks or Salesforce. The owner of this fork, mirandaaldana, has not added any custom description, so what the README documents is the original IDURAR project rather than any changes specific to this fork. The app is built on what the README calls the MERN stack, meaning MongoDB for the database, Express and Node.js for the server side, and React for the browser interface. The look and feel comes from Ant Design, a popular React component library, and the front-end state is managed with Redux. None of those names matter much for understanding what the app does: it is a web app you install on your own machine or server, point at a MongoDB database, and then use through a browser to track invoices and customers. The headline features listed in the README are invoice management, payment management, quote management, and customer management. The README also mentions inventory, accounting, and HR in a later paragraph, though it does not go into detail about any of them. Getting started is described as a nine-step process that mostly lives in a separate INSTALLATION-INSTRUCTIONS file: clone the repo, create a MongoDB cluster, edit an environment file, paste in the database connection string, install backend dependencies, run a setup script, start the backend server, install frontend dependencies, and start the frontend. The license is the GNU Affero General Public License v3.0, which the README summarizes as free to use for personal or commercial purposes. The AGPL has stricter conditions than MIT or Apache, so anyone planning to ship this as part of a hosted service should read the actual license text before relying on the README summary.
