How do you audit which vendors have access to dealership systems?
Ask each system of record for a list of active third-party connections and users, compare it against your contract register, and remove what you cannot account for. Most stores that run this find connections belonging to former vendors, individual logins for people who left, and access nobody can explain — each of which is both a security and a data-leakage exposure.
Start with the system of record
Request from the DMS and CRM providers a current list of every integration, every third party and every user with access, including what each can read and write.
Reconcile against contracts
Every access should map to a current agreement with a named internal owner. Anything unmatched is either an undocumented arrangement or a leftover — both should be closed.
Check leavers and former vendors
Access frequently outlives the relationship. Terminated vendors and departed staff are the most common findings, and the easiest to remediate.
Make it recurring
A one-off audit decays. Tie the review to a fixed cadence and to the offboarding process for both staff and vendors, so removal happens at the point of departure.

What is the difference between a DMS and a CRM?
A DMS is normally the operating and financial system of record for deals, accounting, parts and service. A CRM is normally the sales and customer-workflow system for leads, communications, appointments and follow-up. A suite may include both, but the data and workflow boundaries still need to be documented.
Integration verificationHow do you verify a dealership software integration?
Verify both named products and versions, applicable dealerships, data objects, fields, direction, frequency, authentication, provider, fees, monitoring and support ownership. A partner logo or marketplace listing is only a discovery signal.
Write-back definitionWhat does bidirectional integration or write-back mean?
Bidirectional generally means data moves in both directions, while write-back means one system can update another system’s record. Neither phrase is complete until the exact objects, fields, triggers, conflict rules and timing are stated.
Open DMS meaningWhat is an open DMS?
“Open DMS” has no single controlling definition. It may refer to APIs, certified integrations, customer-authorized data access, export capabilities or a commercial marketplace. Dealers should replace the label with specific access and portability requirements.
