Apache OFBiz is the enterprise resource planning system a company installs when accounting, inventory, orders, and the factory floor must all agree with each other in real time. One shared data model connects the modules, so a sales order entered by the CRM team immediately reserves stock in the warehouse, schedules a pick list, and posts the receivable to the general ledger when it ships. The catalog manager handles unlimited stores, categories, and product variants with price rules and a promotion engine, and the built-in e-commerce storefront and point of sale sell from the same inventory your warehouse counts. Manufacturing plans production with bills of materials, routings, and MRP runs that propose purchase orders for missing raw materials, then costs every job as it moves through the shop. Accounting is proper double-entry: accounts receivable and payable, invoicing, payments, fixed assets with depreciation, budgets, and financial reports across multiple organizations. Facility tools manage several warehouses with lot and serial tracking, receiving, returns, and physical inventory counts, while the HR module keeps positions, contracts, expenses, and performance reviews. Party management unifies customers, suppliers, and employees into one record, REST and service APIs expose every function to integrations, and project and work effort tools track tasks against orders.
