ERPNext is a free and open-source Enterprise Resource Planning system, a type of all-in-one business management software that replaces multiple separate tools for accounting, inventory, sales, purchasing, manufacturing, HR, and project management with one unified platform. ERP systems are typically expensive commercial products, so ERPNext provides a fully featured alternative that businesses can self-host without licensing fees. The system covers a broad range of business functions: accounting and financial management, stock and warehouse management, manufacturing workflows, customer relationship management (CRM), sales and purchase order processing, human resources and payroll, and project tracking. All these modules share a common database and interface, meaning information entered in one area (such as a sales order) automatically flows into others (such as inventory and accounting) without manual re-entry. ERPNext is built on top of the Frappe Framework, an open-source full-stack web application framework developed by the same company. The framework handles the underlying infrastructure, user management, form generation, reporting, REST APIs, and database interaction, while ERPNext provides the business logic on top. It requires MariaDB as its database. Someone would use ERPNext when running a small to medium-sized business and needing a single system to manage finances, stock, employees, and customer relationships without paying for SAP, Oracle, or similar commercial ERP systems. The tech stack is Python and JavaScript on the Frappe framework, with MariaDB as the database.
