DMS Data Integration Compared: Reynolds, CDK, Tekion, Dealertrack
Quick answer: every major DMS exposes data through its own certified program, and the cost and timeline differ sharply. Reynolds charges per rooftop through a certified interface. CDK routes through Fortellis and DMS Data Connect. Tekion has modern REST and event APIs. Dealertrack uses DMI extracts. Expect $200 to $500 per rooftop per month in vendor fees and two to four weeks per rooftop through a packaged platform.
