GM Dealer Co-Op Advertising and How to Use Every Dollar
Co-op money is part of your advertising budget that someone else helps fund, yet many stores let some of it lapse. This guide to GM dealer co-op advertising covers how these programs generally work and the habits that help you use what you have earned.

How co-op advertising generally works
In a manufacturer co-op program, the dealer earns advertising funds tied to vehicle sales or purchases. When the dealer runs advertising that meets the program rules, a share of that cost can be reimbursed from those funds. The details that matter to you sit in the program guidelines: how funds accrue, what share is reimbursed, which media qualify, and how long you have before funds expire.
Those details change. Treat anything you remember from last year as out of date and read the current guidelines in your dealer portal, or ask your program contact or zone representative. This article is general guidance, not program terms. Review compliance questions with counsel and your program administrator.
Four things to look up before you spend
- Your available balance and expiration dates. Know what you have and when it lapses.
- Eligible media. Confirm whether the channels you plan to use qualify, including social advertising, video, search and events.
- Creative requirements. Logo use, model naming, required disclaimers, and rules about showing competing brands or used vehicles in the same ad.
- Approval and claim steps. Whether creative needs approval before it runs, what proof is required afterward, and the deadline to submit.
Write the answers on a single sheet and give a copy to every vendor who produces advertising for you.
Why claims get denied
Most lost co-op money is not lost to bad advertising. It is lost to paperwork. The common causes are simple:
- The ad ran before approval was received.
- Required disclaimers or logos were missing or the wrong size.
- New and used vehicles, or more than one brand, were mixed in a way the rules do not allow.
- The invoice did not match the campaign dates or did not itemize the media.
- Proof of performance, such as screenshots or run reports, was not saved.
- The claim was submitted after the deadline.
Every one of these is preventable with a checklist.
A monthly co-op routine
Give one person ownership of co-op, usually the marketing director or office manager, and have them run the same steps every month.
- First week: pull the balance and expiration dates. Plan the month’s eligible campaigns around them.
- Before launch: send creative for approval if required and save the approval in a shared folder.
- During the campaign: capture screenshots of live ads with dates visible.
- At campaign end: collect itemized invoices and performance reports from each vendor within a week.
- Last week: submit claims and log each one with the date, amount and status. Follow up on anything pending from the prior month.
The GM should see a one-line summary monthly: funds earned, funds claimed, funds at risk of expiring.
Ask your vendors the right questions
A vendor who understands co-op saves you hours. Before you sign, ask:
- Have you produced advertising under manufacturer co-op programs before?
- Will you build creative to the current brand guidelines and revise it if approval comes back with changes?
- Will you provide itemized invoices and proof of performance in the format the program requires?
- Who on your team do we call when a claim is questioned?
Spend co-op on advertising you can measure
Reimbursed money still deserves a result. Whatever the program allows, favor campaigns where you can count what happened: conversations started, set appointments, shown appointments and units sold. A dated sales event promoted on Facebook and Instagram, with a team answering messages and setting visits, gives you a clear before and after. Confirm eligibility for that kind of campaign under the current guidelines before you count on reimbursement, and judge it the same way you judge any other spend: by cost per sale.
Frequently asked questions
Does social media advertising qualify for co-op?
It depends on the current program rules and how the campaign is built. Check the eligible media list and creative requirements, and get approval first if the program asks for it.
What happens to co-op funds we do not use?
Programs typically set an expiration window. Check your dates monthly so nothing lapses unnoticed.
Who should manage co-op at the store?
One named person with authority to hold vendors to deadlines. Shared responsibility is how claims get missed.
