A CRM (Customer Relationship Management) system allows companies to efficiently manage lead and customer interactions, while an ERP (Enterprise Resource Planning) can provide a single source of truth for all the processes of a company. Edilclima S.r.l., a Piedmontese SME (Small or Medium Enterprise), has the necessity to enhance their current system, which can already handle many of their internal procedures, but cannot be updated to keep up with the new technologies and markets needs. This thesis aims to identify a comprehensive CRM/ERP solution suitable for a SME, evaluating both a custom system and the adoption of an existing platform, focusing on the new needs of Edilclima.
