Value leaks in a multi-market media arrangement precisely where the level at which media is planned and bought does not match the level at which the agency is contracted. The wider that gap, the more falls through it. Understanding where those gaps sit is not an argument against network deals, it is the foundation for getting full value from one.
You have negotiated a network arrangement. One contract, one governance structure, a single point of accountability. That is exactly what you wanted. Yet when the numbers come back from individual markets, something does not quite add up. Conditions feel softer than expected. Reporting looks comparable on the surface, but the figures do not tell the same story across borders. Local marketing teams are concerned, and sometimes say so. This is a familiar situation. And it has a structural explanation.
What a network deal genuinely delivers, and what it does not
Before examining the gaps, it is worth being fair about what a central arrangement actually delivers. One contract and one governance structure reduce the overhead of managing multiple agency relationships. Consistent reporting frameworks give headquarters a single view across markets. One strategic conversation at senior level means your brand positioning is not being reinterpreted twenty times over. Platform-level corporate arrangements, joint business plans and enterprise agreements with the major digital platforms, exist at holding and network level and can represent real value in terms of service, support and access.
These are genuine benefits. For many organisations, they justify the model entirely. This article is not a case against network deals. It is a case for knowing precisely what those benefits contain, and at which level they sit.
What a central deal barely touches is locally negotiated media conditions. Local Out of Home, local radio, local television are in any market negotiated locally, by a local trading team, against local rate cards, with local broadcasters and sales houses, whatever the network affiliation. Prices for comparable inventory differ enormously between markets, which is exactly why they are set at market level. A central deal that promises buying improvement across twenty markets is, in most cases, promising something the central level largely cannot deliver. The conditions where most of the money sits are created where the money is actually spent.
The structural gaps where value leaks
Global vs local media buying creates five distinct leakage points. Each is a structural feature of multi-level arrangements, not a sign of agency misconduct. Naming them clearly is the first step to closing them.
Underneath all of them sits one principle: media should be handled at the level where it is planned and bought. Where that is central, handle it centrally. Where that is local, handle it locally. Neither level is the right answer on its own, and the real question in a multi-market arrangement is whether the two connect properly. Value leaks at the seam between them, not at either level in isolation.
The gap between central commitment and local execution. What was agreed at headquarters must land in every local market, and often nobody checks whether it does. Service levels, transparency provisions, commercial conditions, each of these may be written into the master contract and unknown to, or interpreted differently by, the local agency. A local market team that was never briefed on the central terms cannot implement them. And where the terms did arrive, they are not always understood the same way. The result is a central promise that sits in a contract, and an execution that follows local habits. Keep in mind, local media agencies may sometimes not be fully owned by the HQ.
Local leverage that disappears with the local relationship. This one is less visible than the others because it does not sit in a contract clause or a definition. Where an agency is appointed centrally, the local team on both sides knows the account is not going anywhere on local grounds, and that changes the dynamic. Sometimes it drifts: attention moves to other accounts, response times slip, the sharper thinking goes elsewhere. Sometimes it is more deliberate than that, and service levels are set at a level that would not survive a market where the client could walk. Both happen. Neither is universal, and plenty of local teams work exactly as hard on a centrally appointed account as on any other. But the risk is inherent to the structure, and an advertiser who has removed the local incentive without putting anything in its place should not be surprised by it.
If there are early signals, they usually come from the advertiser’s own local marketing team. Concern, frustration, a sense that things are not what they were. Those signals are easy to dismiss as local dissatisfaction with a central decision, and they are frequently the opposite: the people closest to the work reporting what the consolidated numbers will only show much later, if at all.
The remedy is not to give local markets a veto over the central appointment. It is to make sure the local client organisation carries real weight: someone with standing, someone whose view on service is taken seriously, someone the local agency team deals with as a client rather than as the recipient of a decision taken elsewhere. Where a local agency team feels the local client has no say at all, the dynamic is unhealthy whichever way it expresses itself. Open friction is at least visible, and in that sense the easier version. The one where nothing is said and the service quietly settles at a lower level is the harder problem, because by the time it shows up in the numbers it has been running for a year.
Income negotiated at levels the advertiser does not see. The reasonable starting point is that all income related to an advertiser’s spend is defined and disclosed. The multi-market dimension adds a specific complexity: aggregation creates levels an advertiser may have no line of sight into. Where a network arrangement covers many advertisers across many markets, there could be income at that level which relates to aggregate spend rather than to any single client. Whether there is, and how it would be treated, is not something an advertiser can establish from their own figures. What they can do is ask, and require that the contract defines income at every level of the arrangement rather than only at the level they can see. The fee question itself is addressed in detail in media agency fees and the outcomes a selection should return.
Platform-level arrangements. Joint business plans and enterprise agreements with major platforms exist at holding and network level, and their commercial terms are not published. That is not in itself an accusation, since confidential terms are ordinary in commercial arrangements. But it does mean an advertiser cannot establish from the outside what those terms contain, or how they relate to their own spend. What the advertiser can establish is whether the questions get answered: who holds the commitment, who receives the benefit, and is that visible anywhere in what I am shown. An arrangement where those questions have clear answers is in a different position from one where they do not.
Currency, definition and measurement differences between markets. What gross and net mean differs from market to market. What constitutes a delivered impression, a GRP or TRP, net reach, a viewable unit or a valid click is measured differently across markets and platforms. Definitions that look consistent in a consolidated report can conceal fundamental incompatibilities in the underlying data. A number that means something different in every market is not a benchmark. It is a category error dressed up as comparison. This matters particularly when you are trying to assess whether a local market is performing to the standard the central deal described.
These structural gaps are one reason why consolidating your agency roster without closing the governance gap often produces less saving than expected: the deal structure changes, but the leakage points remain.
Why local market conditions are set locally
It is worth dwelling on the local trading point, because it is the one most often misunderstood when a network deal is first agreed. Media markets vary fundamentally in their structure. The dynamics of advertising in Southeast Asia, where broadcaster concentration, digital penetration and agency trading structures differ significantly by country, are a clear example of conditions that no central arrangement can homogenise. A commitment made at network level about buying conditions in markets the central team does not directly trade is a commitment that depends entirely on local implementation.
This is not a criticism of network models. It is a description of how media markets work. And understanding it changes how you write the contract.
What a central structure does deliver, and this is worth stating because it is the other side of the same coin: reach when something needs to be fixed. Consider an advertiser entering a market where the infrastructure is not yet in place. If the problem sits with a platform that is handled centrally, an international liaison can resolve it once, at that level. If it sits with a local medium, it has to be worked out market by market, and without someone whose job is to hold the international picture together, there is nobody positioned to do that.
That is a real argument for central coordination, and it belongs beside the leakage points rather than in opposition to them. The question is not whether coordination has value. It is whether the coordination reaches the level where the media is actually bought.
Closing the gap rather than avoiding the model
The answer to multi-market value leakage is not to avoid network deals. The benefits described above, governance, consistency, strategic alignment, platform-level access, are real. The answer is to close the gap between what is contracted centrally and what is executed locally.
In practice, this means four things. Contract the central promises so they are enforceable at market level: not aspirational commitments in a preamble, but obligations with named accountability. Define every income stream at every level of the arrangement, in the master contract and in each local service agreement. Keep definitions consistent across markets, agree on what gross and net mean, what a delivered impression means, and apply those definitions everywhere. Then verify at market level whether what was agreed centrally is what actually arrives. That verification is a standing task rather than a single check, and what such an arrangement involves in practice is set out under vendor management.
Advertisers who do this capture what the central deal genuinely offers, and keep what the local level genuinely delivers. Those who do not often find themselves with the governance overhead of a network model and the buying conditions of an unmanaged local one.

Frequently asked questions
What is the difference between global and local advertising? Global advertising refers to campaigns planned and contracted at a central level, typically through a network or holding company arrangement, with the intent of consistent messaging across markets. Local advertising refers to the actual execution of paid media in individual markets, where buying conditions, rate cards and broadcaster relationships are determined locally. The two levels operate through different commercial levers, which is the root cause of most multi-market value leakage.
Does a global media deal make local buying cheaper? Mostly no. Locally traded media, television, out-of-home, local digital inventory, is negotiated locally against local market conditions, whatever the network affiliation. What a global deal genuinely delivers is governance, consistency and platform-level arrangements with major digital platforms. The honest question is whether those central benefits actually reach the advertiser or remain at the holding, network or platform level in between.
What are the different types of media buying in a multi-market context? Broadly: centrally negotiated platform arrangements, handled at holding or network level with major digital platforms; regional or market-cluster deals, where a regional hub negotiates on behalf of a group of markets; and locally executed buying, where a local agency team buys directly against local inventory and rate cards. Most advertiser budgets sit in the third category, which is why local execution quality determines most of the outcome, regardless of central deal structure.
How do you verify that a central media deal is actually being implemented locally? Verification requires three things: a contract that creates local obligations, not just central ones; consistent definitions of key terms (gross, net, delivered impression) written into both the master agreement and local service agreements; and market-level auditing that checks whether the conditions agreed centrally are the conditions that appear in local trading data. Without local verification, a central promise remains a central promise, it does not automatically become local reality.
