Managed service is a way of buying advertising in which the platform's own team plans, launches and optimises campaigns on the advertiser's behalf. The advertiser supplies a brief, a budget and creative; the vendor's account managers do the work inside the software and send back reports. The model exists because operating a demand-side platform (DSP), the software buyers use to bid on inventory across many publishers, takes skills and staff that many advertisers lack. It is the counterpart of self-serve, in which the buyer holds the controls. The two usually share inventory and technology; they differ in who operates them and what that labour costs.

Amazon's description is the clearest current example. Its DSP offered "self-service and managed-service options", according to Amazon Ads, and the managed tier "typically requires a minimum spend of $50,000 (minimum may vary per country)".

How a managed service campaign works

The sequence starts outside the platform. An advertiser or its agency signs an insertion order (IO), the contract that fixes budget, flight dates, targeting goals and price, and commits to the vendor's minimum. The account team translates the brief into settings: audiences, inventory sources, deal types such as private marketplaces or programmatic guaranteed deals, frequency caps and bid strategy. During the flight it adjusts bids and budgets, and at the end it delivers reports.

Pricing reflects the labour. Amazon's pricing transparency guide, published to comply with the European Union's Digital Markets Act (DMA), states that "the managed services fee is a percent-based fee added to the media cost, and invoiced as a separate fee". It sits on top of a technology fee, which Amazon describes as a charge "in exchange for system access and standard campaign management functionality", disclosed when a campaign is set up. Self-service customers pay no management fee, according to Amazon. Amazon does not publish the percentages. PPC Land's reading of Amazon's partner documentation, published when the company launched its ad tech activation partners programme in July 2025, put the Amazon-managed route at a 15% service fee plus a 10% platform fee, or 25% of media spend.

That same programme shows that managed service is not a single tier but a ladder. Partner-managed campaigns run through an outside firm's seat cost 22% to 25% of media in total, according to the article, with minimums set by each partner. Self-managed access through a partner seat, with no minimum, cost 9% to 15%. The fee steps down as the buyer takes on more of the work.

The sell side has its own version. Google Ad Manager's Multiple Customer Management (MCM) lets a "parent publisher" operate inventory for a "child publisher", according to Google's help documentation. Under Manage Account, the child grants account access and the parent works inside the child's network; earnings can be paid to the parent automatically, with the split set anywhere "from 0-100%", and always 100% for resellers. Under Manage Inventory, the child delegates ad requests to the parent's own network, and "parent publishers receive full payment for Google monetization". A child can have one Manage Account parent but up to 15 Manage Inventory parents. Monetisation firms using these arrangements act as managed service providers for supply.

Origin and evolution

Before programmatic trading, online display was largely sold managed by default: ad networks bought inventory from publishers, resold it to advertisers and decided where ads ran. Many early DSPs of the late 2000s kept that structure, with the vendor operating the software.

Rocket Fuel is the standard case. AdExchanger described its original offer as "an ad network (or managed service) that claimed to use automation". The company bought X+1, a self-serve DSP and data management platform, in August 2014, which gave it "an opportunity to add a new dimension to its managed service model", the publication reported. By April 2016, chief executive Randy Wootton told AdExchanger the business was "about 10% self-serve platform and 90% managed service", and that the managed model made it "hard for people to understand the value we brought to the chain".

The Trade Desk built the opposite proposition. Its registration statement, filed on August 22, 2016, described "an intuitive self-serve platform that enables our clients to manage data-driven, digital advertising campaigns using their own teams", under headings including "We Are a Clear Box, Not a Black Box".

The balance shifted over the following five years. A survey of 336 brand and agency advertisers, each spending at least $1 million a year on digital media, published by Advertiser Perceptions in October 2021, found 56% relying on an agency or DSP to operate campaigns and 46% managing their own, with overlap between the groups, according to AdExchanger. Some 52% planned to increase self-serve budgets; only 17% planned to raise managed service spending. Amazon's self-serve share among its users rose from 41% to 60% between waves.

Why it matters for marketers

Managed service sets the entry price for some of the most sought-after inventory. Amazon's $50,000 minimum has for years separated large brands from the long tail of sellers. New formats can launch managed first: Amazon's conversational ads on Alexa+ were available only to managed-service buyers at launch on April 7, 2026, before they reached self-service line items on June 17.

The model also shapes vendors' revenue. When clients leave managed service, the vendor loses the labour margin even if the technology contract survives. Criteo disclosed in May 2025 that its largest retail media client would discontinue managed services in November while staying on its technology under a multi-year contract, with an impact estimated at about $75 million for the first ten months of 2026. Chief executive Michael Komasinski said the company was "evolving from a largely managed service model to a more scalable self-service platform". By February 2026, two retail media clients were moving from managed services to self-service technology.

Smaller advertisers experience managed service mainly as a barrier. RTB House's retargeting engine had required "managed service arrangements that smaller brands often cannot sustain" until it launched the self-serve rtb.com on March 4, 2026. Criteo opened GO to US and UK advertisers on March 31, 2026, aimed at businesses that "previously fell outside Criteo's managed-service threshold".

Limitations and disputes

The oldest complaint concerns opacity. When a vendor both runs the campaign and sells the media, the buyer sees results but not always the decisions behind them: which publishers were bought, at what clearing price, and how much went to the vendor. Rocket Fuel's founder George John felt obliged to say: "We're not a black box." The Trade Desk's "clear box" heading was a direct commercial response to that criticism.

Cost is the second objection. A managed tier priced at 25% of media, as reported for Amazon, means a quarter of the budget pays for platform access and labour before any impression is bought. Nanigans chief operating officer Marc Grabowski argued in an AdExchanger column that "a self-service option often costs a fraction of the managed services". Platform fees are themselves disputed: PPC Land's analysis of the margin war set reported Amazon fees near 1% against 12% to 15% at The Trade Desk.

Conflicts of interest are structural: a team running campaigns on its own company's inventory, and reporting sales attributed to its own ads, marks its own homework.

The line between the two models is also blurrier than the labels suggest. "Even self-serve platforms are doing managed service, for some accounts or behind the scenes," Kevin Mannion, chief strategy officer at Advertiser Perceptions, told AdExchanger in 2021. Criteo, for its part, said in November 2026 that it was "phasing out standalone self-registration while using agentic tools to automate key onboarding steps", a reminder that pure self-serve is not always where vendors end up.

What it is not

Self-serve uses the same inventory with a different operator: the buyer. PPC Land's explainer on self-serve covers that model in depth.

Managed service provider (MSP) in information technology is a third party that "remotely manages a customer's IT infrastructure and end-user systems", according to TechTarget. The industry body MSPAlliance traces the term to "the mid to late 1990s ASP sector", meaning application service providers. The advertising term concerns campaign operation, not infrastructure.

Agency trading desks and holding company programmatic units also operate DSPs for clients, but they sit between the advertiser and the platform. Their fees are agency fees or markups, not a platform's managed services fee.

White label describes rebranded technology. A reseller can offer a white-labelled DSP self-serve or managed, as PPC Land's white label explainer sets out with Amazon's fee tiers.

Recent developments

Amazon has reorganised the product around which its managed tier was best known. Its DSP page now says "Amazon DSP is now part of Amazon Ads Agent", with programmatic buying available through DVA+, and states that the pricing model "including self-service and managed-service options, continues within DVA+". PPC Land noted that the buying product became DVA, with Ads Agent the layer on top. The four-step DVA+ campaign builder, in US closed beta since September 29, 2026, hands targeting, inventory and bidding to Amazon's software.

Agency mechanics are changing alongside. Agencies will lose Amazon's legacy DVA fee setting after January 31, 2027, moving to five fee methods applied at account, campaign or ad group level. PPC Land's coverage of Amazon's 34-country account consolidation asked whether the agency is the next layer to go.

Criteo's third-quarter results, released on November 4, 2026, put a number on the shift. Retail media revenue fell 23% to $52 million, with a $20 million headwind from scope changes at two retail media clients, while GO served about a third of Commerce Growth customers and roughly 10% of that segment's revenue.

Summary

Who: Platforms that operate campaigns for clients, including Amazon Ads, Criteo, RTB House and, historically, Rocket Fuel; the advertisers and agencies that buy through them; resellers and activation partners offering managed seats; and, on the sell side, Google Ad Manager parent publishers managing inventory for others under MCM.

What: A buying model in which the vendor's own team plans, runs and optimises campaigns for a percentage fee on top of media and technology costs, usually above a spending minimum such as Amazon's typical $50,000. It contrasts with self-serve, in which the buyer operates the platform.

When: Managed operation was the default for ad networks and early DSPs in the late 2000s. Self-serve gained ground from The Trade Desk's 2016 listing onward, a 2021 survey showed buyers shifting budgets away from managed service, and Criteo, RTB House and Amazon all repositioned their managed offers between 2025 and 2026.

Where: Programmatic display, video and connected TV buying through DSPs, retail media networks, new formats such as Alexa+ and ChatGPT ads at launch, and publisher monetisation through arrangements such as Google's MCM.

Why: Managed service lets advertisers without trading expertise reach complex inventory and lets vendors earn a labour margin. Its costs, its opacity and the conflict of a vendor grading its own campaigns explain why buyers with in-house skills have moved to self-serve, and why vendors are automating what account teams once did.
