Sona
DMS landscape

The DMS was built for the office. We sit on top, then underneath.

Tekion, CDK, and Reynolds run the dealership. We do not displace the billing and GL they are bought for. We displace the workflow surface they never built well, and we own the data layer underneath it.

The incumbents

Built for GMs and accountants. Never for the bay.

CDK Global

~15,000 dealers, Brookfield-owned. A 2024 ransomware breach and a ~$630M antitrust settlement now force open third-party data access. The window is open right now.11

Reynolds & Reynolds

The duopoly's other half. Private, accounting-strong, innovation-slow.

Tekion

2,500+ rooftops, $4B+ valuation. Cloud-native and aggressive, but execution is uneven and its native chat sits unused in the bay.

What is actually sticky

Six things hold a DMS in place. We do not fight the three that matter most.

Sona does not touch this
1
GL and accounting
Externally enforced by audit.
2
OEM certifications
The warranty-submission gate.
3
Lender integrations
RouteOne, DealerTrack.
Sona displaces this, plus the data layer underneath
4
Internal IT skill specialization
5
Multi-department workflow change
6
Corporate vendor relationship
Weakest of the six.

The GL, OEM certifications, and lender integrations are externally enforced. We leave them in place. The workflow surface, the part dealers use a hundred times a day, is the part the DMS never built well. That is what we take.

Where this goes

We do not fight the DMS. We become the layer it depends on.

Today
The DMS owns everything

Billing, GL, workflow, and whatever data falls out of it. The technician gets a terminal built for the front office.

State B, the realistic 10-year picture
Sona owns the workflow and the data layer

The DMS becomes a billing and GL backend behind us. We eat ~60 to 70% of the DMS budget over time. Plaid for dealerships.
