ERP and CRM serve different purposes. ERP focuses on managing internal business operations such as finance, inventory, production, supply chain, and HR. CRM, on the other hand, focuses on customer relationships, including leads, sales, marketing, and customer support.

ERP covers the entire organization, while CRM is customer-centric. Many modern businesses use ERP systems that include CRM modules. Companies often prefer custom ERP software because it allows seamless integration of ERP and CRM features into one system, improving coordination between sales teams and operational departments.
