Metasfresh is a free, open-source ERP system that runs the whole commercial life of an industry or trade company, from the first lead and quotation through sales orders, warehouse shipments, manufacturing orders, and the invoices that close the books. The CRM module keeps business partner master data for customers and vendors, tracks prospects, leads, tasks, and opportunities, and shows the sales pipeline. Sales staff create quotations, convert them into sales orders with credit limit checks and Incoterms, and follow each order through shipment planning to the customer invoice. Purchasing mirrors the flow on the vendor side: procurement planning and purchase dispositions generate purchase orders, goods receipts book deliveries into stock, and vendor invoices match what actually arrived. Manufacturers work with bills of materials, MRP II planning, and manufacturing orders that consume components and finish products, and production planning ties resources to schedules. The warehouse module manages storage locations and handling units, books inventory movements between warehouses, and counts physical stock, so promised quantities match what the floor can actually ship. Accounting posts invoices, credit notes, and reversals for debtors and creditors with automatic FACT accounting entries, keeping the ledger current. Every screen is a responsive web interface that adapts from office monitors to tablets on the warehouse floor, and a REST API connects shop systems and third-party tools to the same data. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPLv2 and GPLv3 dual licensed.
