How should a dealership handle duplicate customer records?
Decide which system is the master for customer identity, define the matching rules explicitly, and make merging a governed process rather than something individuals do ad hoc. Duplicates are not primarily a data-cleanliness problem — they cause missed equity opportunities, repeated marketing to the same household and service history split across records.
Name the master
Identity has to resolve somewhere. Usually the DMS holds the transactional truth and the CRM or CDP holds the marketing view. Whichever you choose, write it down, because unstated ownership is what produces conflicting records.
Define matching before buying a tool
What makes two records the same person: exact email, phone, name plus address, household? The rule set determines the results far more than the software does.
Merging must be reversible and logged
Merges destroy information. Require an audit trail and the ability to unpick a bad merge, and restrict who can perform one.
Fix the intake
Duplicates are created at write-up and lead capture. Validation at the point of entry prevents more duplicates than any periodic cleanup.

What software do car dealerships use?
Most dealerships use a DMS as the operating and financial backbone, plus a CRM, website/CMS, inventory tools, digital retailing, communications, marketing, analytics, F&I and fixed-operations systems. The right combination depends on franchise obligations, market, store count and operating model.
DMS versus CRMWhat 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.
Dealership software pricingHow much does dealership software cost?
There is no dependable universal price because dealership software is commonly quoted by rooftop, module, user, usage, media spend, data volume or transaction. Compare a three-year total-cost schedule instead of a headline monthly amount.
Vendor shortlist sizeHow many dealership software vendors should be evaluated?
A dealership should discover the broad market, apply objective eligibility gates, and conduct deep evaluations with the smallest set that still preserves a real choice—often two to four finalists. The correct number depends on the category and how many providers meet non-negotiable requirements.
