What is the difference between ERP and CRM?

The functions of a CRM and an ERP system are strongly interlinked, but there are differences. Where ERP is oriented toward what's happened, CRM is focused on future actions. ERP, for example, records what a customer has bought and when as well as when the goods were paid for. On the other hand, CRM focuses on winning new customers and binding them to the company. What's important is the interconnection between ERP and CRM that guarantees the constant exchange of data.
