Omnicom Wants to Be Paid for Outcomes: What to Write Into the Contract

If you are renewing an agency contract this autumn, expect the fee conversation to change. The largest agency group now says it wants to be paid more for results and less for hours, and independent agencies will be pitched against that offer. Before anyone agrees to it, both sides need to know what "outcome-based" means once it is written into a contract.

What Omnicom said on September 10

Speaking at Goldman Sachs' Communacopia and Technology Conference on September 10, Omnicom CFO Phil Angelastro said headcount would fall from about 120,000 at the end of 2025 to about 105,000 by the end of 2026, according to Investing.com's transcript summary. MediaPost and DecisionMarketing reported that as roughly 15,000 job cuts. The reduction comes from duplicated corporate and regional management roles, outsourcing and offshoring, and businesses Omnicom is selling; MediaPost names the sale of the experiential agency Jack Morton earlier this year. DecisionMarketing reports the restructuring will have very little impact on client-facing people.

The same Investing.com summary puts the gross cost-synergy target from the Interpublic acquisition at $1.5 billion over the next couple of years, with 20 to 30 percent reinvested in the first year, mainly in the Omni platform, agentic AI and training staff to use it. Omnicom had already raised its 2026 organic growth guidance with its second-quarter results on July 28, to 5 percent from 4 to 4.5 percent; Investing.com's conference summary gives the outlook as 4.5 to 5 percent.

For clients, the pricing remarks matter most. Investing.com records Angelastro saying "the model in terms of how we get remunerated from our clients is going to transition" and that it would happen "over a period of time." He pointed to Flywheel Digital, Omnicom's commerce business, where 80 to 90 percent of the work is outcome-based. ExchangeWire describes the shift as a move away from hourly and fixed-fee models, aimed at growing revenue with less reliance on headcount, and reports Angelastro saying the shift will unfold gradually and will not apply uniformly.

Two limits on what is known. The 15,000 figure is the difference between two headcount totals, not an announced layoff programme, and no split between redundancies, attrition and disposals was given. And nothing we read says how Omnicom defines an outcome, measures one, or shares the risk.

What an outcome-based fee contains once it is written down

Few agency contracts pay only for results. The common shape is a base fee that covers the cost of doing the work, plus a variable portion paid when agreed targets are met. The base protects the agency from factors it cannot control; the variable portion is where the incentives sit. Every term in that variable portion needs a definition, and each definition moves risk from one side to the other.

Selling on retail marketplaces is close to the easiest case for outcome pricing: the sale is recorded in the same place the ad runs, the path from spend to revenue is short, and both sides can see the same numbers. Brand building, B2B lead generation with a long sales cycle and anything sold offline are harder, because the result arrives late and much besides the agency's work shapes it. Expect the model to spread first where measurement is cleanest.

Data ownership deserves its own clause. An outcome fee is calculated from data, and whoever holds that data effectively writes the invoice. Angelastro told the conference that better measurement would let Omnicom prove the return it delivers to clients, per Investing.com. The party that controls measurement therefore controls the fee. If payment depends on the agency's platform, the client needs access to the underlying records and the right to take them when the contract ends. If it depends on the client's CRM, the agency needs audit rights and a written rule for when a lead counts as qualified.

Questions to ask before you sign

1. Which single metric triggers payment, and does it measure the business or only the channel?
2. Is payment based on platform-reported results or on incremental lift, and if lift, who designs the holdout?
3. What is the baseline, and what happens to it if prices change, a product launches or the budget is cut mid-year?
4. Which system is the source of truth, and do both sides have access to the raw data behind every invoice?
5. What share of the total fee is at risk, and is there a cap on the upside?
6. If the agency is paid on revenue, will it still recommend spending less when less would work better?
7. What happens to the fee, the data and the ad accounts if either side ends the contract?

What it means for independent agencies

A large holding company can offer outcome pricing because it spreads risk across many clients and funds the platforms that measure results, which is where Omnicom says part of its synergy savings is going. A small agency cannot carry a large variable fee on a client whose results depend on things it does not control. That is not a reason to refuse the conversation. It is a reason to structure it.

• Offer a narrow outcome, not a broad one. Tie a modest share of the fee to one metric you can influence and measure, such as qualified leads from paid search, rather than to total revenue.
• Lead with measurement. If you can run a clean holdout test and show incremental lift, you can price on it.
• Compete on who does the work. Omnicom says the cuts barely touch client-facing staff, but a client can reasonably ask who will run its account after a year of consolidation, and a smaller agency can answer that plainly.

Earlier this month we looked at PepsiCo's move of its global media account to Publicis, and at what it said about buying media as an operating model. Outcome pricing is the same trend applied to the fee: the client pays for what the system produces rather than for the people inside it. Whether that works in your favour depends almost entirely on the definitions, so write them down before the first invoice, not after.
