There are four major types of CRM systems: collaborative CRM, Operational CRM systems, Analytical CRM systems and all-in-one CRM solutions. Collaborative CRM systems enable companies to connect multiple departments and ensure their organized daily work based on single-source customer data. Operational CRM systems focus on streamlining and automating diverse workflows for customer-facing teams. Analytical CRM systems specialize in providing in-depth business intelligence based on customer data. All-in-one CRM systems support not only customer-facing use cases, but they enable organizations to automate back-office workflows and operations.
