What is a Dealer Management System (DMS)?
A Dealer Management System (DMS) is the core software of a car dealership or automotive business. It consolidates all business processes—from vehicle and customer management to quotes, orders, and invoices, as well as the service department, parts management, and accounting —into a single system. The goal of a DMS is to enter data only once and make it available across all departments.
CATAMA is a modern cloud-based DMS: You don’t need a local server, maintenance, or expensive IT infrastructure. All users work in real time with the same data—at the dealership, in the repair shop, and while working from home.
What a Modern DMS Covers
Vehicle Fleet
New and used cars, including costs, downtime, and documentation—with vehicle management and integration with vehicle marketplaces.
Customers & CRM
Centrally manage prospective and regular customers, track inquiries, and manage follow-ups.
Invoicing & Accounting
Quotes, invoices, e-invoices, and bookkeeping —all in one seamless process with DATEV export.
Interfaces
Integration with mobile.de, DAT, parts catalogs, and manufacturers via the CATAMA interfaces.

Why a cloud-based DMS?
- No need to purchase servers, no maintenance, automatic updates
- Location-independent access via a browser on a PC, Mac, or tablet
- Data storage in a German, GDPR-compliant data center
- Scales from a one-person operation to a team of several people
- GoBD-compliant, audit-proof document management
DMS or Document Management System?
The abbreviation “DMS” has two meanings. In the automotive industry, DMS stands for Dealer Management System —that is, the central dealership software discussed on this page. There is also the Document Management System for the digital storage and archiving of documents. CATAMA offers both: The Dealer Management System manages your business processes, while the integrated Document Management System ensures the audit-compliant archiving of your documents.
If you're in the retail business, it's also worth taking a look at our dealership software.
