ERP (Enterprise Resource Planning)

One system of record for finance, inventory, sales, purchasing and HR, so every department works off the same numbers.

An ERP (Enterprise Resource Planning) system is a single application that runs a company's core operations — accounting, inventory, purchasing, sales and HR — on one shared database. The point is not the feature list but the single source of truth: when a warehouse records a delivery, finance sees the liability and sales sees the stock, without anyone re-keying it.

An ERP replaces the collection of spreadsheets and disconnected apps most companies accumulate with one system where a transaction is recorded once and everyone downstream sees it.

The practical test of whether a business needs one is not size, it is reconciliation: if your team regularly spends time working out which of two numbers is correct, that is the cost an ERP removes.

What it typically covers

Finance — general ledger, receivables, payables, fixed assets, reporting
Supply chain — inventory, purchasing, warehousing, landed cost
Sales — quotations, orders, invoicing, and the link back to stock
People — employee records, payroll, leave, attendance

Common open-source options include ERPNext and Odoo; the large proprietary vendors are SAP, Oracle and Microsoft Dynamics.
