ERP (Enterprise Resource Planning) software is a single integrated system that runs a company’s core processes, from finance and purchasing to sales, inventory, manufacturing and HR. Instead of separate spreadsheets and apps, every department works on the same data in real time.

Why companies use ERP
Without ERP, sales may promise stock that the warehouse does not have, and finance learns about costs weeks later. ERP connects these steps so that a sales order automatically checks stock, triggers production or purchasing, and posts accounting entries.
Core ERP modules
| Module | What it handles |
|---|---|
| Finance and accounting | General ledger, payables, receivables, assets, GST and tax reporting |
| Controlling | Cost centres, product costing, profitability |
| Sales and distribution | Quotations, orders, pricing, delivery and billing |
| Procurement | Purchase requisitions, orders, vendor management |
| Inventory and warehouse | Stock levels, movements, batches |
| Production planning | BOMs, routings, MRP, shop floor |
| Human resources | Employees, payroll, attendance |
| Project management | Budgets, schedules and project costs |
| Maintenance and service | Equipment, repairs and service orders |
End-to-end processes ERP connects
- Order-to-Cash (O2C): from customer order to payment.
- Procure-to-Pay (P2P): from requirement to supplier payment.
- Record-to-Report (R2R): from transactions to financial statements.
- Hire-to-Retire (H2R): the employee lifecycle.
- Plan-to-Produce: from demand plan to finished goods.
