What is the difference between CRM and ERP?

In short: CRM supports the work leading up to and surrounding the customer, while ERP supports what happens within the organization to deliver and settle accounts. The two overlap more than vendors like to admit, and it is in this overlap that most implementation projects go awry.

CRM — the revenue side

CRM stands for Customer Relationship Management. The system keeps track of who the customers and prospects are, what has been said and agreed, which sales are in progress, which customer service cases remain open, and which marketing activities people have been exposed to. Its value lies in ensuring that everyone who speaks with the customer has the same overall picture.

ERP — operations

ERP stands for Enterprise Resource Planning and covers accounting, invoicing, purchasing, inventory, production, and payroll. The requirements for accuracy and traceability are stricter here because the figures must reconcile with the accounts and withstand an audit. An ERP system is rarely something you improvise.

Where they meet

The customer, product, and order typically exist in both systems, and these three are precisely what spark debate. Our advice is to explicitly determine ownership for each object before integrating anything at all: which system is the source of truth for customer information, which one owns the price list, and at what point does an order move from CRM to ERP? Without this clarification, you end up with two systems that both believe they are correct, and the organization then spends more time reconciling data than selling.

Do we need both?

Most businesses have an accounting system long before they acquire a CRM system. The question is therefore rarely “CRM or ERP,” but rather “what are we missing?” If the problem is that no one knows what has been communicated to the customer, that the sales forecast is a spreadsheet, or that inquiries are falling through the cracks, then CRM is the solution. If the problem is late invoices or inaccurate inventory figures, CRM will not help.
