inoERP
What inoERP is
inoERP is a free, open-source enterprise management system for small to midsize businesses. Its documented modules cover finance, inventory, purchasing, sales, order management, manufacturing, supply-chain planning, costing, and human resources. Finance includes multi-company accounting, financial management, and reporting; HR covers employees, jobs, positions, compensation, payroll, leave, and approval hierarchy. The system uses a Go back end, Flutter front end, MySQL, and OneApp JavaScript APIs, with database and JavaScript code available on GitHub. It is designed for on-premise deployment, and a Go-based server is listed for Windows, Linux, and macOS. REST APIs let users configure forms, actions, reports, charts, and workflows. The maker describes integrations with Oracle E-Business Suite, SAP HANA S/4, Microsoft Dynamics 365, and custom ERP, PLM, MES, and quality systems, plus no-code API connections. A dynamic pull system recalculates supply quantities from actual demand before creating requisitions, purchase orders, or work orders. The web client is experimental, with fewer functions and lower performance than native clients.
