The Great Remuneration Reset: Is advertising about to change the rules for everyone?

WPP has announced a decisive pivot. Under its “Elevate28” strategy, the world’s largest agency network is moving away from hourly billing and staff-count-based fees toward compensation tied directly to measurable business outcomes - sales growth, ROI, market share impact.

For someone like me, who has seen the 15% commission era, the time-cost era, and now the AI era, this feels less like evolution and more like rupture.

For most of the 20th century, the 15% media commission was sacred. Agencies earned when clients spent. The incentive was scale. The 1990s dismantled that orthodoxy. Procurement entered the room. Fees became linked to hours, headcount, and cost sheets. Agencies were no longer rewarded for impact; they were compensated for effort.

Now comes the third shift.

AI-driven production has fundamentally reduced the cost of creative output. When content can be generated faster and cheaper, billing by time becomes structurally fragile. If output is abundant, time loses its scarcity value. In that context, performance-based remuneration is not ideological it is an economic necessity.

But will others follow?

Some industries already operate on performance-linked compensation. Private equity and hedge funds charge performance fees. Investment bankers earn success fees on deals closed. Sales professionals live on commission. Even real estate brokers are paid only when transactions happen.

In consulting, outcome-based pricing has existed for years in selective mandates, turnaround assignments, cost-reduction programs, digital transformation tied to measurable savings. However, most professional services still rely on time-based billing because outcomes are complex and causality is hard to isolate.

Which brings us to the ethical dilemma.

Should doctors be paid only when patients recover? Intuitively attractive  but dangerously simplistic. Health outcomes depend on variables beyond a physician’s control: genetics, compliance, lifestyle, socioeconomic factors. Tying pay purely to recovery could incentivize risk avoidance, doctors declining difficult cases to protect their “performance metrics.” In medicine, society has chosen to pay for expertise and effort, not guaranteed results. By moving to a performance based system, have we finally abandoned our position of providing expertise to clients?

Advertising sits somewhere in between.

Unlike medicine, its primary objective is commercial which is growth, demand generation, revenue acceleration. Outcomes are measurable. Attribution models are increasingly sophisticated. Yet even here, variables are shared: pricing strategy, product quality, distribution, competitive intensity. If agencies are paid purely on performance, will they demand greater control over marketing mix decisions? Will they refuse clients with weak products? Will creative boldness diminish if compensation depends on short-term sales spikes?

Performance-based remuneration aligns incentives  but it also redistributes risk.

The larger question is whether this signals a philosophical shift across knowledge industries. For decades, expertise was sold as time. Now, technology compresses time. When AI can generate in minutes what once took weeks, clients will inevitably ask: “Why should I pay for hours when I care about outcomes?”

Advertising may not be the first industry to propose performance pay  but it could be the first to attempt it at global scale.

If WPP succeeds, competitors will not have the luxury of doggedly clinging to hourly billing. Market forces will compel adaptation. If it fails, the industry may retreat to hybrid models ; base retainers plus performance bonuses.

What is certain is this: the old revenue certainties are gone.

The 15% commission died quietly. The hourly model may not die quietly at all.

And in that turbulence lies a deeper question - not just about agencies, but about how society values expertise itself.
