DMS versus CRM

What is the difference between a DMS and a CRM?

A DMS is normally the operating and financial system of record for deals, accounting, parts and service. A CRM is normally the sales and customer-workflow system for leads, communications, appointments and follow-up. A suite may include both, but the data and workflow boundaries still need to be documented.

Different primary jobs

The DMS posts and controls dealership transactions. The CRM organizes relationship and sales activity before, during and after a transaction.

02

Where they overlap

Customer identities, vehicle interests, deal status, sold information and service opportunities may appear in both. The important issue is which system owns each field and how changes synchronize.

03

How to test the connection

Create a representative lead, appointment, showroom visit, deal and sold record. Trace every field across both systems, including duplicates, opt-outs, reassignment and corrections.
