Agencies behave rationally in response to the incentives their commercial arrangements create. Understanding those incentive structures — and what they point toward — is an essential dimension of commercial governance for any significant agency relationship.
Incentive Structures as the Hidden Architecture of Agency Behaviour
When an agency relationship consistently underdelivers — when work is safe rather than distinctive, when recommendations seem to expand scope without obvious strategic rationale, when media allocations appear to favour particular channels regardless of the strategic brief — the temptation is to attribute the problem to the agency’s capability or commitment. Frequently, the problem is structural. The agency is behaving rationally in response to the incentives its commercial arrangement creates.
Understanding how an agency is commercially structured — what generates revenue, what drives margin, what the business model rewards at the individual and organisational level — is essential context for any senior marketing leader or CMO managing a significant agency relationship. It is also context that is rarely examined explicitly. Client organisations tend to engage with what the agency proposes without examining the commercial logic that shapes why it proposes it.
This is not a cynical view of agency behaviour. Most agency professionals are genuinely motivated by the quality of their work. The question is whether the commercial structures that govern their relationships allow that motivation to express itself in the client’s interests, or whether they create systematic pressures that point in a different direction.
Media Agency Incentive Structures and Their Implications
Media agency compensation structures are among the most contested and least transparent in the marketing industry. The traditional commission model — where the agency earns a percentage of media spend — creates a direct incentive to recommend higher spending, particularly in channels where commissions are highest. This incentive persists even in agencies that have formally moved to fee-based structures, because volume rebates, agency volume bonuses, and proprietary trading desk arrangements can preserve de facto commission economics beneath a fee-based surface.
The agency’s recommendation cannot be fully evaluated without understanding the commercial consequence of that recommendation for the agency itself. Transparency about incentive structures is not a courtesy — it is a governance requirement.
The ACCC’s 2023 examination of media agency transparency in Australia surfaced practices that had been industry-standard for years: undisclosed rebates, principal media arrangements where agencies traded inventory for their own account, and volume commitments to media owners that influenced channel recommendations. The finding that these practices existed did not reflect individual bad faith — it reflected the predictable consequence of commercial structures that had never been subjected to adequate client scrutiny.
Creative Agency Scope Expansion and the Revenue Motivation Behind It
Creative and full-service agencies face a different set of incentive pressures. The primary revenue risk for a creative agency is scope contraction — the client reducing the volume of work, bringing disciplines in-house, or moving tactical execution to lower-cost alternatives. The agency’s commercial interest is therefore to expand and defend scope, to demonstrate indispensability across as many workstreams as possible, and to resist in-housing or consolidation decisions that reduce the remit.
What Commercial Transparency Actually Requires
Commercial transparency in agency relationships means more than knowing the rate card. It requires understanding the full revenue model — what the agency earns beyond fees, where volume bonuses exist, how media trading arrangements work, and where proprietary financial interests may intersect with client recommendations. For media agencies, the standard for transparency has risen significantly following regulatory scrutiny; for creative and digital agencies, it remains lower than it should be.
The contractual minimum for commercial transparency includes disclosure of all remuneration received in connection with the client’s work, including any rebates, bonuses, or preferential arrangements from third parties such as media owners, technology platforms, or production suppliers. This disclosure standard is not universal in Australian agency contracts and should be sought explicitly in any significant agency appointment.
Beyond contractual disclosure, the ongoing governance of commercial transparency requires regular review of whether the agency’s recommendations are consistent with the client’s interests when the full commercial context is understood. This review is most naturally conducted by a procurement or finance professional with direct access to the agency’s revenue disclosures — not by the marketing team that manages the day-to-day relationship.
Building Relationships Where Incentives Actually Align
The goal of understanding agency incentive structures is not to create adversarial relationships — it is to design commercial arrangements where the agency’s financial interests and the client’s commercial interests are genuinely aligned. This alignment is achievable. Performance-based components that reward the agency for commercial outcomes rather than for hours or spend naturally align incentives. Transparency obligations that require disclosure of all third-party remuneration remove the incentive to favour commercially advantageous recommendations over strategically appropriate ones.
For Australian boards and executive teams, the question is whether the commercial architecture of their major agency relationships has been designed with this alignment in mind, or whether it has been inherited from standard industry practice without examination. The commercial stakes are sufficient to justify the examination — and in most cases, the examination reveals opportunities for alignment that the existing arrangements have left on the table.
