What is an ERP, and how does it differ from accounting software?
Accounting software records what happened; an ERP also governs how it happened. Accounting has the invoice but not which order, which work order and which shipment produced it.
The difference shows in one question: when a customer calls to ask where last month’s order stands, who answers? In accounting software that question has no owner. In an ERP it does, because order, production, stock and dispatch belong to the same record.
Which modules make up an ERP?
The core is usually purchasing and suppliers, stock and warehouse, production, sales and orders, dispatch, finance and accounting, with reporting above them. Depending on the business, quality, maintenance, field service or a dealer channel are added.
But the module list is not the decision. What matters is whether those modules are built around the company’s real flow; most packages have the modules and impose their own flow.
How do you know a company needs one?
The measure is neither turnover nor headcount. Three signs are more reliable: the same data is kept in two places, answering one question requires asking several people, and the month-end close is a negotiation rather than a calculation.
If even one is true, the company is already running a system — one scattered across files and people. The ERP decision is not building a new system but collecting the one that already exists.
What does it actually give the company?
The return shows up in three places. Decision speed: the hours spent gathering data disappear, so decisions can be made the same day. Cost visibility: scrap, downtime and discounts surface without waiting for month end.
And the least discussed one, transferability. When knowledge sits in the system rather than in people’s heads, one person leaving does not take the company’s memory with them.
