The business

An HVAC-components maker funded dealer co-op marketing on loose, largely unmonitored terms, trusting its distributors to promote the brand in their local campaigns. Co-op support was a standard part of the channel relationship, and because the arrangements had grown up informally over years, what the co-op money was actually being spent on was rarely checked.

What triggered the audit

Co-op spend kept growing while the brand’s share of dealer campaigns visibly didn’t, a mismatch that suggests the money wasn’t buying what it was meant to. The audit reviewed what the co-op funds were genuinely being spent on across distributors, testing whether the brand was actually getting the promotion it was paying for.

What the audit found

The co-op program was, in a number of cases, funding the competition. Because the terms were loose and reimbursement required little proof of how the money was used, distributors were spending co-op funds on campaigns that promoted rival brands alongside — and sometimes more prominently than — the maker’s own products. The brand was effectively subsidizing marketing that drove leads and sales its competitors also benefited from, all under the banner of supporting its own channel. Because nobody audited the funded campaigns or tied reimbursement to brand presence, this had quietly become an accepted cost of doing business. Tightening the terms and requiring proof of performance stopped the leak, which across the distributor base amounted to roughly $69k a year of co-op spend working partly for the competition.

How we produced this finding

The co-op funds finding was produced exactly the way MarginFix runs every manufacturing audit: spend put through the A.I Marketing Orchestrator that runs the agentic AI audit framework, then tested for causation rather than credit. What you’re reading isn’t an opinion — it’s an evidenced read a senior auditor signed off before it was ever shared.

Data sources: Spend by channel, campaign, creative and audience, joined to conversion and revenue data — plus a geo-holdout test built to isolate what co-op funds genuinely caused rather than what it merely claimed.

Key frameworks: Geo-holdout incrementality testing, Marketing Mix Modeling (MMM) and attribution-correction and inflation-factor analysis, cross-checked against Analytic Partners ROI Genome, Google Meridian and Meta Robyn.

Human validation gate: Every incrementality read is re-run against your own data and signed off by a named senior auditor before it ships — no automated output ever leaves the building unreviewed.

Working paper: co-op budget spent promoting rival brands traced line by line and reconciled to invoiced margin in the P&L over a matched period. Line items representative and redacted; the recovered figure is the reconciled audit finding.

What we changed

Tightened co-op terms to require exclusive or clearly majority brand presence in any funded campaign, so the money can no longer promote rivals alongside the brand.

Required proof-of-performance before any co-op reimbursement, so funds only flow to campaigns that genuinely and demonstrably promote the brand paying for them.

Added spot audits of funded campaigns, keeping the tightened terms honest across a large and dispersed distributor base.

Preserved genuine co-op support for the distributors who promote the brand properly, protecting the channel relationship while cutting the waste.

The result

$69k a year recovered by ensuring co-op money promotes the brand paying for it, not its rivals — a 12× return on the $5,950 Audit + Sprint fee. For any manufacturer, loose co-op terms felt like normal channel support, while funds quietly bankrolled campaigns pushing competitors alongside you. If your co-op spend isn’t tied to proof of brand presence, you may be subsidizing the very rivals you’re trying to beat. It takes reviewing what the money actually bought to see it. A fixed-fee audit does that in days and ties every reimbursement to performance.

From kickoff to signed-off findings: 7 days — inside our fixed 5–7 day window.
