If the 2020s were about one question – “How do I get more impressions?” – then 2026 is asking something sharper:
“Where is the money actually going?”
While global ad spend surged to $1 trillion – up 10.5% year over year (eMarketer 2025), something else surfaced beneath that growth: agencies lost $26.8 billion to hidden fees and opaque supply mechanics.
What once looked like isolated billing discrepancies revealed by large holding groups like Omnicom and Publicis is now widely understood as a systemic issue – one that raises a fundamental question: how much of the media budget is actually reaching the media?
Why fragmentation has a price tag
Out of every $1,000 invested into a DSP campaign, only about $439 (43.9%) typically reaches verifiable media. The rest is absorbed by platform markups, data add-ons, and resale spreads layered across the supply chain.
According to ANA’s 2025 data the TrueAdSpend index has fallen to 37%, while programmatic waste in the US has climbed to $26.8B, up 34% since 2023. At the same time, nearly half of advertisers still overpay for low-quality MFA inventory.
Losses are distributed across multiple layers: a markup here, an add-on there, a hidden opt-in somewhere in between. Together all of those can make your ROI unrecognizable.
How hidden fees quietly take over
The challenge is that these inefficiencies rarely appear as explicit costs. They are embedded directly into the buying process – through automated add-ons, bundled optimization features, reseller layers, and limited access to log-level data.
On paper, campaigns look fully optimized. In practice, agencies often lose around 15–25% of their budgets to fee opacity, while client retention declines. While no platform can eliminate all external supply-side costs, having centralized visibility and control ensures that no part of your budget is lost without explanation.
This creates a disconnect: dashboards may show stable performance, but the underlying economics tell a different story – one where budget efficiency erodes quietly across the chain.
Fragmentation as main challenge for agencies
Another gap that became increasingly obvious in 2025 is that many DSPs are still built with single advertisers in mind – not agencies managing dozens (or hundreds) of clients.
That mismatch creates friction everywhere:
- multiple logins
- fragmented billing
- limited control over user permissions
- manual reporting processes
This model is not sustainable for agencies in 2026. In 2026, agencies need:
- a single account managing multiple clients
- role-based permissions across teams
- unified billing flows with full transparency
- customizable reporting and automated alerts
Agencies need a centralized single point where they can manage and operate efficiently. In fact, 62% of responders cited integration and workflow flexibility as the most wanted in the modern DSP infrastructure (along with API activation for agency workflow).
In other words, there’s a big shift in how agencies think about DSPs. Instead of treating them as black-box buying platforms, DSPs are becoming infrastructure partners – expected to provide control layers, transparency tools, and operational flexibility.
By bringing transparency, control, and visibility into one system, agency accounts don’t just simplify operations – they rebuild trust in how programmatic actually works.
What you can manage with SmartyAds DSP Agency access
SmartyAds DSP created the Agency Access that works as a single command center for managing all advertiser accounts in one place. Agencies no longer need to switch between dashboards or systems – everything is accessible through one login with unified campaign oversight.
Within this structure, agencies can manage multiple client accounts, define role-based permissions for teams and advertisers, and maintain full visibility over who can access and modify campaigns, creatives, and budgets.
Transparent financial operations
Financial management is also centralized at the agency level. Instead of fragmented billing across accounts, agencies operate through a unified billing environment with a single agency balance.
From there, funds can be distributed across advertiser accounts, with full control over deposits and withdrawals. This creates full visibility into how budgets are distributed across accounts, eliminating hidden layers and giving agencies direct control over where their spend goes. And, this removes one of the biggest sources of operational friction in agency workflows.
Reporting built for clients, not systems
Reporting is critical in a landscape where clients increasingly demand transparency – not just performance numbers, but clarity on how those numbers are achieved. At our DSP it is designed to support real agency-client communication. Agencies can generate customized, on-demand performance reports, track results across advertisers, and set metric-based reports that speed up feedback loops.
The result is not just cleaner reporting, it is faster alignment between performance data and client decisions.
Why agencies adopt it
The value is not only operational efficiency, but structural simplification. Agencies reduce time spent on administrative tasks, scale client operations without proportional headcount growth, and provide clients with more immediate and transparent insights.
More importantly, they move from managing fragmented systems to operating within a unified environment designed for agency-scale complexity.
The shift behind the tool
Across the industry, DSPs are being redefined. They are no longer expected to function purely as buying platforms, but as infrastructure layers that provide transparency, control, and operational flexibility.
In that context, agency-first systems like SmartyAds DSP Agency Access are not an enhancement, they are a response to how modern programmatic buying actually works.
