#How co-op actually works
A manufacturer accrues funds for a dealer, usually as a function of vehicles delivered, and reimburses a share of qualifying advertising spend against that accrual. The accrual expires on a schedule — monthly, quarterly or annually depending on the programme — and unclaimed funds do not carry forward indefinitely.
What qualifies is defined by the programme, and every manufacturer's programme is different. Typical requirements cover which media are eligible, which vendors are approved to produce or place the advertising, how the brand and logos must appear, what disclaimer text must be present, how long the brand must be visible or audible in video and radio, and what documentation must accompany the claim.
The reimbursement share also varies, and it is common for different media to reimburse at different rates. That is worth knowing before planning, because it changes the effective cost of channels relative to each other in a way that no media plan built without it will reflect.
#Why claims fail
Almost never eligibility. The store is enrolled, the funds are accrued, the media is a qualifying type. Claims fail on the details: a logo at the wrong size, a disclaimer missing a required line, brand exposure a second short of the minimum, an unapproved production vendor, or a submission that arrived after the window closed.
Every one of those is decided at the point the creative is produced, and every one is cheap to satisfy if the requirements are in front of the person producing it. They are expensive to fix afterwards because the ad has already run.
The structural cause is a split of responsibility. The agency produces the creative and knows the campaign. The controller or the co-op administrator files the claim and knows the requirements. Neither sees the other's constraints at the moment that matters, which is the brief.
#The brief is where co-op is won
The fix is procedural and it is not complicated: put the programme's creative requirements into the creative brief template alongside the legal disclosure requirements, and treat them the same way — as constraints the concept is designed around rather than as a checklist applied at the end.
That means the brief states the required logo treatment, the required disclaimer text verbatim, the minimum brand exposure, the approved production and placement vendors, and the submission deadline for that flight. It also means somebody checks the ad against the brief before it runs, not before it is claimed.
Stores that do this find their claim success rate changes without anything else changing, and they usually also find they were producing creative through a vendor that was never approved — which is the single most expensive discovery to make after the fact.

What belongs in a co-op-aware creative brief
Every item here is decided at the brief and is expensive or impossible to fix after the ad has run. Get the current requirements from your programme portal each flight, because they change.
| Brief item | Why it belongs at the start | If it is missed |
|---|---|---|
| Approved production vendor | Some programmes reimburse only work produced by listed vendors | The whole flight is non-claimable, regardless of the creative |
| Approved placement or media vendor | Placement is often restricted separately from production | Media spend does not qualify even where creative does |
| Logo treatment and size | Determines layout, not decoration | A partial claim or a rejection on an ad that already ran |
| Required disclaimer text, verbatim | It has to fit legibly at the size the ad will run | Rejection, or an unreadable ad with the type crushed at the bottom |
| Minimum brand exposure duration | Video and radio have to be timed for it from the edit | Re-edit after the flight, if it is even possible |
| Co-branding and tagline placement | Affects the concept, not the finish | Rejection on an otherwise compliant ad |
| Submission window and required documentation | Invoices, tear sheets and proofs have to be collected as you go | The funds expire — the most common single cause |
| Reimbursement rate by media type | Changes which channels are actually cheapest | A media plan built on the wrong relative costs |

#Co-op changes what your media plan should look like
Because reimbursement rates commonly differ by media type, the effective cost of channels relative to one another is not what the rate card says. A channel reimbursed at a higher share can be materially cheaper in real terms than one that looks cheaper on paper, and a media plan built without that information is optimising the wrong number.
This is one of the few genuinely automotive-specific things about dealership media planning, and it is a reasonable test of whether an agency knows the category. An agency that has never asked about your co-op programme is planning your budget without one of its main inputs.
It is also why the dealership advertising budget should be built with co-op in it rather than treating reimbursement as a rebate that arrives later. The rebate changes the decision, so it belongs in the decision.
#The parts nobody wants to own
Documentation is the unglamorous half. Invoices, tear sheets, screenshots, broadcast affidavits and proofs of performance have to be collected while the campaign runs, because assembling them two months later is how deadlines get missed.
Somebody has to own the calendar of submission windows, and it should be somebody who will still be there next quarter. In practice this works best when it sits with whoever owns the vendor relationships rather than with the controller, because the documentation comes from the vendors.
And somebody should reconcile what was claimed against what was accrued, at least quarterly. Stores that do this occasionally find they have been leaving a consistent share behind for years for a single repeatable reason — which is a much better problem to have than an unexplained one.
