The Programmatic Toll Booth: Why Indie Agencies Feel Trapped by DSP Fee Structures

By Kimeko McCoy | October 21, 2026

For independent advertising agencies, the promise of programmatic advertising was once a level playing field: a democratization of media buying that allowed smaller players to compete with the gargantuan budgets of global holding companies. However, a growing chorus of frustration from the independent sector suggests that the "open" web is increasingly governed by a series of closed-door financial barriers.

Ten media buyers and agency executives recently spoke with Digiday, painting a picture of an industry where the path to direct access to Demand-Side Platforms (DSPs)—specifically The Trade Desk and Amazon DSP—is not a meritocracy based on performance, but a shifting landscape of "toll booths" that drain margins and offer little in return.

The Reality of the "Reseller Trap"

For a 15-person New York-based agency, the journey to independence has been fraught with frustration. Despite hitting the $100,000 monthly spend threshold—a figure often cited as the "golden ticket" to direct status—the agency remains shackled to a reseller. Currently, they pay a 17% fee to The Trade Desk, compounded by an additional 12% fee to Mogl, the reseller they were ostensibly supposed to outgrow upon reaching their spending targets.

"They won’t let us go direct and they won’t change the fees," said an executive familiar with the negotiations. "So we told them, ‘We’re not running with you,’ and we only have very little spend on them now."

This sentiment is echoed by agencies from Washington state to Texas. These firms find themselves caught in a loop: they are steered toward resellers to facilitate their initial entry into programmatic, only to find that the exit ramp—a direct contract—is permanently under construction. When the agency attempts to bypass the middleman, they are met with moving goalposts regarding spend requirements, leaving them paying for tech and service fees without receiving the corresponding support.

Chronology of a Growing Conflict

The tension between independent agencies and the programmatic giants has been brewing for years, but it reached a boiling point in 2026.

• Early 2023: The industry begins to see an influx of smaller agencies attempting to leverage DSPs like The Trade Desk and Amazon for programmatic buys. Resellers are positioned as the primary entry point.
• March 2026: Publicis Groupe experiences a highly publicized fallout with The Trade Desk. While the dispute was eventually settled, the industry caught wind of a central issue: a lack of transparency regarding fee structures. This signaled to the rest of the market that even the largest holding companies were struggling with the opaque nature of DSP costs.
• Summer 2026: A wave of independent agencies reaches their internal spending targets, expecting to transition to direct relationships. Many are denied, citing undefined "commitment levels."
• August 6, 2026: During an earnings call, The Trade Desk CEO Jeff Green defends the platform’s premium positioning, arguing that advertisers are increasingly fixated on price rather than the inherent value and performance of the technology.
• Present Day: Independent agencies are actively diversifying their tech stacks, moving away from major DSPs to explore alternative platforms to escape the "toll booth" model.

Supporting Data: The Cost of Intermediation

The financial burden of these arrangements is significant. In a standard programmatic ecosystem, the agency fee is the primary cost. However, when a reseller is inserted into the supply chain, the agency incurs a "double dip" of fees.

For example, a Washington-based agency reported paying a 10% reseller fee on top of Amazon’s 15% platform fee. Totaling a 25% overhead before a single ad is even served, this structure renders the agency’s campaigns less efficient and less competitive.

The lack of transparency is the secondary insult. Agencies report that the support provided by these resellers is often negligible, essentially serving as a billing intermediary rather than a strategic partner. "We are having to pay some more of those platform and tech fees to go through the reseller without a lot of support there," one executive noted.

Official Responses and Corporate Stance

When pressed for comment, the platforms maintain that their policies are designed to accommodate the varying needs of their diverse client base.

The Trade Desk’s Position

A spokesperson for The Trade Desk emphasized that the company remains open to all advertisers. Regarding the transition to direct relationships, they noted that direct seats are contingent upon "commitment levels agreed-upon with each client." The spokesperson added: "Should clients want to work with The Trade Desk without a direct agreement for whatever reason, they are welcome to use our certified resellers, such as Goodway Group and Mogl, and still see the benefits of our Kokai Zuma platform."

Amazon’s Stance

Amazon’s position is somewhat more ambiguous, reflecting the "shifting sand" described by agency executives. According to a company spokesperson, there is no minimum spend threshold for Amazon ads. However, they clarify that some advertisers prefer hands-on help through service partners—which often act as resellers—to handle the complexities of setup, strategy, and optimization. The company maintains that the decision to use a partner is often a choice for the agency, rather than a hard requirement imposed by Amazon.

Implications for the Future of Programmatic

The current friction has profound implications for the ad tech ecosystem. As indie agencies feel "squeezed out," the market is witnessing a shift in behavior.

1. The Rise of Alternative Tech

The monopolistic grip of the "big three" (The Trade Desk, Amazon, and Google’s DV360) is beginning to loosen. Agencies are increasingly experimenting with niche or mid-tier DSPs that offer more transparent fee structures and direct access, even for smaller budgets. The "Digiday Scorecard" reports suggest that buyers are gaining the confidence to move beyond the industry behemoths, prioritizing control and cost-efficiency over the perceived brand safety of the largest platforms.

2. The Demand for Transparency

The fallout between Publicis and The Trade Desk has emboldened smaller agencies to demand better visibility into how their money is spent. The "black box" of programmatic fees is no longer an acceptable standard. As the industry matures, agencies are likely to move their budgets toward platforms that provide clear, itemized fee breakdowns.

3. A Potential Consolidation or Equity Crisis

If the major DSPs continue to prioritize holding companies or large, committed spenders, they risk alienating the long tail of the industry. While they currently argue that their value proposition justifies the cost, a significant exodus of independent agencies could leave the giants vulnerable to disruption. If the market continues to consolidate toward a "pay-to-play" model, the programmatic ecosystem may become less of a marketplace and more of an exclusive club, potentially inviting greater regulatory scrutiny regarding anti-competitive practices.

Conclusion: A Turning Point for Indie Agencies

The conflict between independent agencies and major DSPs is not merely about service fees; it is a fundamental disagreement about the future of digital advertising. For the agencies, the goal is a transparent, equitable system where scale is rewarded with efficiency. For the DSPs, the focus remains on high-value, high-commitment partnerships that ensure long-term platform growth.

As the industry moves into the next year, the "toll booth" model faces a critical test. Will the major platforms adjust their policies to accommodate the smaller agencies that helped build the programmatic web, or will they continue to push them toward the exits? For now, the independent agency sector is voting with its budgets—and the "shifting sand" of DSP policies is driving them toward greener, more transparent pastures.
