ERP

A larger company constantly has to keep track of very different things. How many screws are left in the warehouse? Which invoice is still unpaid? Who’s working the night shift next week? In the past, each department kept its own lists for this, and the numbers rarely matched up. An ERP is software that brings all these areas together in a single system. The abbreviation stands for Enterprise Resource Planning — that is, the planning of a company’s resources: material, money, machines, and working hours.

The backbone of everyday business

The decisive advantage is a shared data foundation. When sales accepts an order for a thousand units, production sees it immediately. The warehouse recognizes that material needs to be reordered. Accounting knows that an invoice will soon be due. Nobody has to manually transfer figures from one system to the next.

This is precisely what makes an ERP critical, though. If it goes down, half the business often grinds to a halt. A hacker attack on a supplier regularly cripples not so much the machines as the software that controls them. Companies therefore run ERP systems with considerable effort put into security and failure protection.

Switching ERP systems is also expensive and risky. Major transitions take several years and cost millions. There are well-known cases where a botched switch caused a corporation’s revenue to noticeably drop. Once a company has introduced a system, it usually sticks with it for a very long time.

Modules around a shared database

Technically, an ERP consists of a central database and many modules built around it. A module is a program component for a specific area, such as purchasing, warehousing, or payroll. All modules access the same data. An item exists exactly once in the system, not five times across five tables.

You can picture it like a school office that keeps a single student file. The homeroom teacher, the sports teacher, and the administration all look at the same file. If a student moves, the address changes in one place and immediately applies everywhere. Without this principle, every department would have its own, outdated copy.

The most demanding part of an implementation is rarely the technology. It’s the question of how a business actually operates. An ERP demands fixed processes: Who is allowed to approve an order? From what amount onward is a second signature required? These rules must first be defined before they can be cast into software. Often, in the end, the company adapts to the software rather than the other way around.

From SAP to AI in the ordering process

The best-known provider is the German corporation SAP, one of the most valuable companies in Europe. There’s also Oracle, Microsoft with Dynamics, and for smaller companies providers like Odoo or Lexware. ERP often shows up indirectly in business news: when a corporation blames a profit warning on problems with a system migration.

A current trend is the move to the cloud. Instead of running its own servers in the basement, a company rents the software from a provider on the internet. This lowers entry costs but increases dependence on the provider. Many companies are currently right in the middle of this shift.

AI is also making inroads. An ERP contains years of sales and inventory data, and that’s exactly what machine learning systems thrive on. They predict which product will run short in the fall, or flag suspicious invoices as possible fraud. A common misconception is that ERP is the same as CRM. CRM manages the relationship with customers — that is, contacts and quotes. An ERP covers the entire internal operation of a business and often includes CRM as just one of many modules.
