Enterprise Resource Planning (ERP)

Short answer: Enterprise resource planning, or ERP, software brings a company's main back-office processes into one connected system. Without it, accounting, purchasing, stock, manufacturing and sales orders often sit in separate tools, each with its own copy of the data. An ERP system records each transaction once, and every department works from that shared record. The term grew out of earlier manufacturing resource planning systems. ERP extended the same idea beyond the factory to the whole business.

People often confuse ERP with customer relationship management software, the system that holds customer and sales records. An ERP system tracks operations: orders, production, stock, shipments, invoices and payments. The customer system tracks contacts, leads, likely deals and service requests. The two are usually connected. When a salesperson wins a deal in the customer system, it becomes a sales order in the ERP system. ERP systems usually come in modules, so a company can start with finance and inventory and add others later. Companies can subscribe to ERP software in the cloud or install it on their own servers.

Take a sales order that staff enter once in an ERP system. The same record can reserve stock and trigger purchasing or production if stock runs short. It can then create a shipment and raise an invoice. Every module reads the same data. So the warehouse, purchasing and accounts teams all see the same figures without copying them between tools. To implement an ERP system, the team maps its processes and configures the system to match them. It then moves core records, such as customers, suppliers and products, into the system. Finally, it connects other tools and trains staff.

A manufacturer handles 1,500 orders a month across three tools: an order spreadsheet, an inventory system and accounting software. Staff re-key each order into all three, which takes about 8 minutes per order, or 200 hours a month. Stock figures often disagree, so the team sells items it does not have about 30 times a month. After moving to an ERP system, staff enter each order once. Stock, purchasing and invoicing all update from that single record. Order handling falls to about 2 minutes per order, or 50 hours a month. The company saves about 150 hours a month and stops most of the overselling.

An ERP system is often the largest single system decision a growing company makes. It shapes processes, reporting and controls for many years. Leaders should treat selection as a business decision with clear process requirements, a realistic total cost and named internal owners. The teams that run orders, stock and purchasing should help choose it, because they will use it every day.

ERP projects often run over budget and schedule when the scope is unclear or the data is poor. They also overrun when the company tries to copy every old habit through heavy customization. Switching ERP systems later is expensive, so lock-in deserves attention at selection. Smaller companies may find that a well-connected set of simpler tools meets their needs for some time.
