What is a Dealer Management System (DMS)?
A Dealer Management System (DMS) is the central software for a car dealership or automotive business. It brings together all business processes – from vehicle and customer management, through quotations, orders and invoices, to the workshop, parts management and accounts – in a single system. The aim of a DMS is to enter data just once and make it available across all departments.
CATAMA is a modern cloud-based DMS: you don’t need a local server, no maintenance and no expensive IT infrastructure. All users work in real time with the same data – at the car dealership, in the workshop and whilst working from home.
What a modern DMS covers
Vehicle inventory
New and used cars, including costs, downtime and documents – with vehicle management and a link to the used car market.
Customers & CRM
Centrally manage prospective and existing customers, track enquiries and manage follow-ups.
Invoicing & Accounting
Quotations, invoices, e-invoicing and bookkeeping with DATEV export in a single workflow.
Interfaces

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 car 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, whilst the integrated Document Management System ensures the audit-proof archiving of your documents.
For pure retail operations, it’s also worth taking a look at our car dealership software.
