What an Amazon marketing services agency actually sells in 2026

Amazon Marketing Services, usually shortened to AMS, was the name of Amazon's self-service advertising console for vendors. In September 2018 Amazon folded AMS, Amazon Media Group and the Amazon Advertising Platform into one brand called Amazon Advertising, later shortened to Amazon Ads, and the old buying platform became Amazon DSP. The three acronyms were dropped at the same time.

So a brand searching for an Amazon marketing services agency today is not looking for a product. It wants a partner to run Sponsored Products, Sponsored Brands, Sponsored Display and sometimes DSP, plus the listing, creative and operations work that decides whether ad spend turns into profit.

The job is more expensive to get wrong each year. Amazon reported $19.6 billion in advertising services revenue for the third quarter of 2026, up from $17.7 billion a year earlier, with growth slowed only because Prime Day moved from July to June.

The four jobs a real agency does

The agency pages that rank for this keyword list eight to twelve services, which makes every agency sound the same. In practice the work breaks into four jobs, and you should know which of them you are buying before you compare prices.

• Advertising in the Amazon Ads console: campaign structure, bids, budgets, negative targeting and search term harvesting across Sponsored Products, Brands and Display
• Programmatic and video: Amazon DSP and Streaming TV, which need a separate budget and only pay off once listings already convert
• Listings and creative: keyword research, titles and bullets, images, A+ Content and the Brand Store that ads send traffic to
• Operations: account health, catalog fixes, inventory planning, reimbursements and brand protection, the work that stops ads from pushing budget behind a product that is about to stock out

How Amazon agencies charge, with 2026 numbers

Fees are where the ranking pages are weakest. My Amazon Guy's page on this exact keyword, published in December 2024, names three fee models but gives no dollar figures. Helium 10's guide says a few hundred to several thousand dollars a month. HawkSEM puts agency costs between $1,500 and $10,000 a month with no breakdown.

SupplyKick's 2026 pricing guide is the most detailed public source. It reports percentage-of-ad-spend fees of 10 to 20 percent, percentage-of-revenue fees of 3 to 10 percent, flat retainers from $1,500 to more than $25,000 a month, onboarding fees of $1,000 to $5,000, early termination penalties of one to three months of retainer, and minimum ad spend thresholds of $5,000 to $20,000 a month at PPC-focused agencies. Its rule of thumb is that total agency fees should sit between 2 and 5 percent of Amazon revenue.

Treat all of these as vendor estimates, because every source is an agency or a tool company. The useful lesson is the shape of the market: most agencies price on scope, most hide the price until a call, and a percentage model raises your fee every time spend rises, whether or not the extra spend was profitable.

Worked example: one brand, three fee models

Take an illustrative brand selling $100,000 a month on Amazon with $20,000 a month in ad spend and 20 ASINs. These numbers are made up to show the math, not a client result.

Under a 15 percent of ad spend model the fee is $3,000 a month. Under a 5 percent of revenue model it is $5,000 a month. Under PPC Spider's published full-service plan it is a flat $1,500 a month, which is 1.5 percent of revenue and inside the 2 to 5 percent guideline with room to spare.

Now grow ad spend to $40,000 a month and sales to $180,000. The ad spend model moves to $6,000 and the revenue model to $9,000. The flat plan changes too, and honestly so: full-service covers up to $20,000 of monthly ad spend and 25 ASINs, so this brand would move to a custom Enterprise quote, while a PPC-only brand would move from the $995 Launch plan to the $1,250 Growth plan, which covers up to $40,000 of spend. A flat plan steps up when scope steps up; a percentage fee creeps up every month.

• 15 percent of ad spend: $3,000 a month at $20k spend, $6,000 at $40k spend
• 5 percent of revenue: $5,000 a month at $100k sales, $9,000 at $180k sales
• Flat full-service plan: $1,500 a month up to $20k spend and 25 ASINs, then a scoped Enterprise quote

What PPC Spider charges, published before the call

PPC Spider publishes every price on the site. Full-service Amazon management is a flat $1,500 a month for up to 25 ASINs and $20,000 of monthly ad spend, with a dedicated account manager, a dedicated ads manager, operations and creative teams, a shared Slack channel, a bi-weekly meeting with written action items, and weekly and monthly reports. Accounts above that band, multi-brand, 1P and 3P or international, get a custom Enterprise quote.

Each department is also sold on its own: Amazon PPC management from $995 a month, DSP and Streaming TV from $1,100, listing SEO from $950 a month or $360 for a single ASIN rewrite, A+ Content from $600 a page, Brand Store design from $840, brand protection monitoring from $480 a month and inventory planning from $600 a month. Every plan includes SpiderOS, our own platform for profit per product, live reports and 24x7 ads automation.

Every plan is a flat retainer, never a percentage of ad spend, with a 90-day initial term and then month to month with 30 days notice. You own the Seller Central and Ads accounts, we work inside them as users you can remove at any time, and the SpiderOS login is yours.

Contracts, access and ownership: the questions the top guides skip

None of the five top ranking pages we read explains who owns the account, what the notice period is or what happens to campaign data when you leave. Settle those three terms in writing before the first invoice.

Ask for user-level access only. A good agency works as a named user inside your Seller Central, Vendor Central and Amazon Ads accounts, never through a login you cannot revoke. If an agency wants to move your campaigns into a manager account it controls, ask what happens to that account on the day you cancel.

Ask for the initial term, the notice period and the termination fee as three separate numbers. SupplyKick reports penalties of one to three months of retainer as common, which on a $5,000 plan is up to $15,000 to walk away from a partner that is not working.

• Who owns the accounts, the campaigns and the historical data on the day you leave?
• What is the initial term, the notice period and the termination fee, each as a number?
• Which named person runs the account day to day, and how many accounts do they run?
• Which metrics are in the weekly report: ACoS alone, or TACoS, organic share and profit after fees?

Checklist: vet an Amazon marketing services agency in five working days

You can verify most of what an agency claims without a sales call. Give the work to one person, usually the marketing or ecommerce lead, and run the five steps below in one week. Each step names where to look and the number that tells you it passed.

• Day 1, marketing lead: search the agency by name in Amazon's partner directory at advertising.amazon.com/partners/directory and record whether its listing shows Advanced or Verified status. A badge on the agency's website with no directory listing fails this step.
• Day 2, finance: put every proposal into one sheet with the fee at your current ad spend and at double that spend. Pass if the fee at double spend is still under 5 percent of projected Amazon revenue.
• Day 3, ecommerce lead: ask each agency for a sample weekly report from a live account with the client name removed. Pass if it shows TACoS, organic share of sales and profit after fees, not only ACoS and ROAS.
• Day 4, owner: request the contract and underline the initial term, notice period, termination fee and account ownership clause. Pass if all four are written down and the accounts stay in your name.
• Day 5, ecommerce lead: ask each agency to describe month one in weeks. Pass if the first two weeks are access and audit, nothing is paused before its replacement is live, and you get a written baseline with profit, rank and stock targets by the end of week two.
• After signing, finance: track agency fee as a percentage of Amazon revenue and TACoS every month. It is working when TACoS falls or holds while total sales grow and the fee stays inside the 2 to 5 percent band.

When you should not hire an agency yet

This advice does not apply to every brand. If Amazon revenue is under roughly $100,000 a year, SupplyKick's guidance is not to hire an agency at all, and we agree: a $1,500 retainer is 18 percent of $100,000 in annual sales, far above the 2 to 5 percent band. Start with a free audit or a single ASIN rewrite at $360 and come back once the listings convert.

It also does not apply if gross margin after Amazon fees is close to zero, because no fee model can buy profit the unit economics do not allow. Fix price, packaging or fees first.

Finally, be careful with partner status as a filter. SalesDuo reported in July 2026 that Amazon had paused new partner status decisions ahead of an updated partner structure, so a strong newer agency may have no badge yet. Use the directory to catch false claims, not to rule out honest ones.
