An ERP (Enterprise Resource Planning) system is an integrated software suite that manages a company’s core processes (finance, procurement, sales, inventory, manufacturing and HR) on a single database, so every department works on the same data without duplication or manual re-entry.
How an ERP works
An ERP is organised in modules sharing one database. When sales registers an order, inventory reserves material, manufacturing raises the production order and finance records the invoice; nobody re-types the data. That transactional integrity is what separates an ERP from a collection of standalone apps. Modern ERPs, such as Odoo, open source and modular, let you start with a few modules and grow, and expose APIs for integration.
Why it matters for industrial SMEs
In an industrial SME the ERP is the administrative and planning backbone: what is bought, stocked, manufactured, at what cost, and what is invoiced. It replaces the parallel spreadsheets each department keeps. Connected to the shop floor, it stops being fed by end-of-shift paper reports and receives real production, consumption and quality data.

Inside the ERP, manufacturing planning is the job of MRP and warehouse management of the WMS. Between the ERP and plant control sits the MES. Connecting the ERP to machines is a typical OT/IT integration case, and Odoo is one of the most widespread ERP suites among SMEs.
