# CRM vs DMS, what's the difference and what does a dealership need?

> Almost every dealership has a DMS (Dealer Management System). Few have a real CRM. The gap typically costs DKK 200-500,000/year in lost upsell and retention. Here's what the two systems do, where they overlap, and why most dealerships need both.

## Short answer (TL;DR)

DMS = operations (accounting, stock, registration, valet). CRM = customers (leads, follow-up, service contracts, upsell, communication). Most DMS systems have a minimal CRM module that isn't used. A dedicated CRM (like CARRUSLiNK) integrates with the DMS and adds the missing layer: customer contact, automation, follow-up, upsell. Result: 25-40% higher earnings per customer without changing DMS.

## Why 'DMS is enough' is an expensive assumption

- The DMS handles car + accounting, but doesn't know a customer was never followed up
- Leads from AutoTrader land in the salesperson's email and get forgotten, the DMS never sees them
- Service contracts run as PDFs, the DMS tracks no conversion, follow-up or renewal
- No automatic communication with customers, everything is manual
- No connection between the salesperson and the workshop, follow-up falls through the cracks
- Management can't see: where do customers stop? which salespeople convert? what's CLTV?

## How to choose. DMS, CRM or both?

### 1. Audit what the DMS REALLY does today

Many think their DMS has CRM features, it might, but are they used? Check: are leads logged? Is follow-up triggered? Do customers get automatic SMS? If the answer is 'no' or 'salesperson does it manually' = you don't have a CRM.

### 2. Don't change DMS, add CRM on top

DMS changes are expensive, long and risky (typically 6-12 mo implementation). In most cases the solution is to keep the DMS and put a modern CRM on top with two-way integration. CARRUSLiNK integrates with most Danish DMS systems via API.

### 3. Define where data lives

Car data (VIN, stock, registration) = DMS. Customer data (leads, communication, contract conversion, upsell) = CRM. Integration keeps them synchronised both ways, salesperson works in CRM, accounting in DMS.

### 4. Bring every touchpoint into CRM

AutoTrader leads, web leads, phone leads, walk-ins, emails, SMS, test drives, service contracts, everything logged in CRM. Otherwise it lives in 'salesperson's email' and the journey is invisible to the rest of the store.

### 5. Let CRM trigger automation

New lead → auto SMS. Car delivered → auto onboarding. KM near service → auto reminder. Contract near expiry → auto renewal. That's the CRM's job, not the salesperson's.

### 6. Measure what the DMS never measured

Lead-to-customer rate. Service contract conversion per salesperson. Trade-in rate from existing customers. CLTV per car model. That's CRM data and it determines how you make more money.

## What a real CRM adds on top of DMS

- **Every customer has one profile** — Lead, test drive, purchase, contract, workshop visit, trade-in, collected on one customer card across departments.
- **Automation on everything repetitive** — SMS flows, follow-up, renewal, upsell, runs itself. Salesperson and reception spend time on what needs a human.
- **Two-way DMS integration** — Car data pulled from DMS, customer actions pushed back. No double entry, no different numbers in two systems.
- **Numbers DMS never showed** — Conversion per salesperson, CLTV per customer type, where leads drop, which seasons stand out, all on dashboard.
- **No DMS change needed** — Keep Autoflex, AutoIT, Workshop Mate or whatever you use. CRM sits on top, without 6 months of implementation.
- **Configured for the car industry** — A real car-industry CRM (not HubSpot or Salesforce) knows what a sales contract, service contract, test drive and loan car are. Save 6 months on setup.

## CRM vs DMS, what does each do?

| Area | DMS (Keyloop, AD Manager, Autoflex) | Dealer CRM (CARRUSLiNK) |
| --- | --- | --- |
| Inventory and vehicle master data | Yes, core | Reads from DMS |
| Accounting, invoicing, bookkeeping | Yes | No (pushes to accounting) |
| Workshop, time and parts | Yes | No |
| Leads from listing portals, web, calls | No | Yes, core |
| Customer card with history and conversations | No | Yes |
| Sales and service contracts (signature, renewal) | Partial | Yes |
| Mobile-first for salespeople on the lot | No | Yes |
| Automated lead and customer follow-up | No | Yes |

## Frequently asked questions

### What's the difference between CRM and DMS?

DMS (Dealer Management System) handles operations: car stock, accounting, registration, valet, workshop, invoicing. CRM (Customer Relationship Management) handles customers: leads, follow-up, service contracts, upsell, communication, customer journeys. DMS answers 'which car and what does it cost?'. CRM answers 'which customers, where are they in the journey, what's next?'. Most dealerships have strong DMS and weak/no CRM.

### Which system should I pick. CRM or DMS?

Wrong question. You need both. The DMS is critical for operations (many dealerships can't change because accounting and stock are locked in). The CRM is critical for growth (without it you never follow up, don't sell contracts, lose customers). The 2026 solution: keep DMS, add a modern CRM on top with integration.

### Can't I just use HubSpot or Salesforce as CRM?

Technically yes, practically expensive. Generic CRMs like HubSpot/Salesforce need to be configured to understand cars, service contracts, loan cars, sales contracts, registration data etc. That typically takes 6-12 months and DKK 200-400,000 in consultant hours. An industry-specific CRM like CARRUSLiNK is configured from day 1 and costs a fraction.

### Do I need to change DMS to get a good CRM?

No. Most Danish DMS systems have APIs that let a modern CRM sit on top. CARRUSLiNK integrates with Autoflex, AutoIT, Workshop Mate and more, so you keep your DMS and get the CRM as the missing layer. No 6-month implementation, no risk of losing accounting data.

### What does it cost to put CRM on top of DMS?

CARRUSLiNK is tiered pricing from DKK 2,299/mo based on fleet size for the full platform including DMS integration. Compared to lost upsell (typically DKK 200-500,000/year on service contracts + trade-in flow alone) it pays for itself in 1-3 months.

### What happens if we change DMS later?

CARRUSLiNK connects to the new DMS via API. Customer data, communication, contracts and all the CRM work follow along. A DMS change doesn't become a CRM change, a big advantage if you consider switching DMS one day.
