Quote to cash in one web application - create quotes, convert them to invoices, record payments, track customers: iDURAR is an open-source ERP and CRM platform for small and medium-sized businesses. Built on the MERN stack (MongoDB, Express, React, Node.js) with Ant Design components and Redux state management, it presents a clean SaaS-style interface that needs little onboarding. Core modules cover invoice management with PDF generation and email delivery, payment recording against invoices, quote and proforma handling, customer records, and accounting views over the resulting data. Multi-currency support and localization make it usable for internationally operating teams. Because the whole stack is JavaScript with an API-first backend, extending it - custom fields, new modules, integrations - is approachable for any Node/React developer rather than requiring a specialist ERP skill set. Deployment is straightforward via Docker with a MongoDB instance. Licensed under AGPL-3.0 with free commercial use; a hosted enterprise version exists but the self-hosted edition is fully functional.

Named after the Bosnian word for invoice (račun) with a raccoon twist, Rachoon provides a clean self-hosted invoicing platform that handles the complete billing cycle from quotation to payment reconciliation without touching a third-party SaaS subscription. The Nuxt.js frontend serves a dashboard that surfaces revenue totals, pending balances, overdue items, and client statistics at a glance, while the AdonisJS backend manages all business logic against a PostgreSQL 16 database with TypeScript throughout the full stack. Invoice templates use Nunjucks with full HTML and CSS control—including conditional logic, loops, and custom formatting—so the rendered PDFs actually match your design intent. This is possible because Rachoon delegates PDF generation to Gotenberg, which renders invoices through headless Chrome rather than a restricted drawing API, producing output that faithfully preserves complex layouts, web fonts, and CSS grid. Client records stay organized and searchable, each linked to their invoice and quotation history with payment status tracking across pending, paid, and overdue states. Multi-currency billing with flexible tax configuration supports international operations, and all data remains on your own infrastructure. The monorepo is managed by Turborepo with a CI pipeline covering linting, PostgreSQL integration tests, build verification, and multi-platform Docker image creation for both amd64 and arm64 architectures. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
