How to Run a Dealership Vendor Audit in One Afternoon
Vendor costs build up quietly, one auto-renewal at a time. A dealership vendor audit puts every contract on the table at once so you can see what you pay, what you get and what nobody would miss.

Step one: build the full list
You cannot audit what you cannot see. Ask your controller for every recurring charge from the last three months across advertising, software, data and lead sources. Include items billed through the manufacturer, charged to a company card or buried in a bundled invoice. For each one, record the vendor, the monthly cost, the contract end date, the cancellation notice period and the name of the person in the store who uses it. Most dealers are surprised by the length of this list, and by how many rows have no clear owner.
Step two: write down what each vendor is for
Next to every row, write one sentence describing the job the vendor does for the store. Keep it concrete: “sends service reminders,” “provides used car leads,” “manages search ads.” If nobody can complete the sentence, flag the row. Then sort the list by job. Overlap shows up immediately. It is common to find two chat tools, three sources of equity alerts or a pair of vendors both claiming to manage the same advertising channel.
Step three: ask each vendor for proof
Send every marketing and lead vendor the same short request.
- What did you deliver for us in the last ninety days, in leads, set appointments or other outcomes?
- Please send the customer list behind those numbers so we can match it to our sales.
- What do you commit to going forward, and what happens if you miss it?
Run a sold match on each list using name, phone and email. Calculate cost per sold unit for each vendor from your own records. For software, ask for usage data instead: how many employees logged in, how often and which features they used. A tool nobody opens is easy to cut.
Step four: grade and decide
Give each vendor one of four grades.
- Keep. Clear job, proven result, fair cost.
- Fix. Useful job, weak result. Give the vendor a written target and a date.
- Consolidate. Duplicates another vendor. Keep the stronger one.
- Cut. No owner, no proof or no use.
Be honest about habit. Some vendors stay for years because the rep is likable or because canceling feels like a chore. Neither is a reason to keep paying.
Step five: read the contracts before you act
Before sending any cancellation, check three things in each agreement: the notice period, the auto-renewal date and what happens to your data when the relationship ends. Put every renewal date on a shared calendar with a reminder well ahead of the notice deadline. Confirm that customer data, ad accounts, website content and social pages remain the property of the dealership. Review termination terms and data ownership clauses with counsel, especially for long-term agreements.
Step six: put the savings to work
An audit is not only about cutting. Decide in advance where recovered budget will go. The best destination is whatever sits at the top of your cost per sold unit ranking, or a test of something new with a defined commitment behind it. When you evaluate replacements, hold them to the standard the audit just set: a clear job, a result you can verify in your own records and a commitment in writing. Short terms and stated outcomes, such as a set appointment minimum, keep the next audit simple.
Repeat the audit twice a year. The second one takes half the time, because the list already exists and every row has an owner.
Frequently asked questions
Who should lead the vendor audit?
The GM, with the controller supplying the invoices and each department manager speaking for the tools they use.
What if a vendor will not share a customer list for matching?
Treat it as a missing answer. A vendor confident in its results has every reason to help you verify them.
Is it risky to cut several vendors at once?
Stagger cuts that affect the same part of the funnel, and watch appointments and sales for a few weeks after each change.
