Marketing Audit
A marketing audit is a structured review of how a company spends to acquire and keep customers: channels, campaigns, agencies, and the technology stack behind them. The standard version reviews surface metrics, which channels converted, which campaigns underperformed, what the dashboards report. It does not review the layer underneath: costs that were approved once, kept renewing, and left the review cycle. In companies operating for more than a few years, that layer holds most of the recoverable profit.
How it actually works
A traditional audit reviews channels, campaigns, and reported metrics, then ranks them by performance. It assumes waste appears as a visible line item. In practice waste is spread across dozens of individually approved costs, each with a rational business case that has not been validated in years.
As a result, a standard audit identifies which campaigns underperformed last quarter and leaves the older approved costs, the ones no current report covers, unexamined.
Those costs accumulate in known patterns: a duplicate tool bought by marketing and again by operations, a subscription still billing after the person who bought it left, an agency retainer that began at a few hundred thousand dollars a year and grew to over a million and a half. Purchased tools bill in full while going mostly unused: the CMO Survey (Fall 2024) found that only 50% of purchased martech tools are being used in operations, down from 56% just six months earlier, and Gartner's 2025 Marketing Technology Survey found only 15% of organizations qualify as high performers who meet strategic goals and demonstrate positive ROI. The costs persist because cutting one requires someone to state that a past decision no longer holds. The financial character of the recovery is what makes the audit worth running: a recovered cost lands in the current period at roughly 100% margin, because no cost of goods and no new spend stands between the cut and the P&L. Against revenue initiatives that carry acquisition cost, execution risk, and a payback period, recovered opex is the highest-certainty EBITDA available.
In practice
One logistics company signed a $65,000-a-year middleware contract, locked in for three years, to connect their systems. The tool did not run on its own; an external team had to be brought in to implement it. The same function was already available in the cloud platform the company had chosen, at a few thousand dollars a year with no lock-in. The contract was signed before the tool produced anything, and a standard audit reviewing campaign performance would not have examined it, because it sat in an approved budget line.
Where we come in
Our diagnostic identifies 15 to 20 percent of operating expenses as recoverable profit, the average across engagements spanning SMBs under $10 million, mid-market, and Fortune 15. The measurement work behind the Potbelly turnaround followed the same order, efficiency proven before budget was added, and we have run this work at the scale of Digital Realty and Equinix.
