You have decided to stop running Amazon on your own. The next question is whether you are buying advice or buying hands.
This covers what each model actually delivers, what both cost at current market rates, how each one fails, and a scorecard that ends in a single answer for your revenue band.
How this comparison was put together:
- Pricing pulled from current retainer structures, consultant day rates, and percentage-of-spend deals rather than quoted from older roundups
- Scope definitions checked against what both models put in an actual statement of work, not what their homepages claim
- Failure patterns drawn from brands who switched between the two models and what triggered the switch
Xneeti manages Amazon accounts, so the bias is worth naming now. Under roughly $250K in annual sales, a one-off consultant and a capable internal hire still beat paying anyone a retainer.
By the end you should know which one to shortlist, and what a fair quote for it looks like.
The short answer, before the detail
Hire a consultant when you do not trust the plan. Hire an agency when you trust the plan and cannot staff it. Most brands get this backwards and buy execution for a strategy nobody has pressure tested.
Hire a consultant if: you have an internal person who can execute, the problem is diagnosis rather than capacity, you are moving onto Amazon from DTC or retail, or you have already burned one agency and need to know whether the strategy or the execution failed.
Hire an agency if: you know what needs to happen and nobody has the hours, your catalogue and campaign count have outgrown one person, or you want a single accountable owner for a number rather than a set of recommendations.
A consultant leaves you with clarity and a to-do list. An agency takes the list away and sends you a monthly report. Year one can cost about the same either way. Only one of them gives you back time.
If both descriptions sound half right, skip ahead to the section on running the two together.
What an Amazon marketing consultant actually does
A consultant is hired to work out what is wrong and what to do about it. The deliverable is a diagnosis and a sequenced plan. Performance is not what you are paying for, and it is not what you can hold them to.
You are buying senior judgment by the hour, without paying for the junior team that usually sits underneath it.
What the work usually covers
- A structured account audit covering campaign architecture, listing quality, catalogue health, and brand protection
- Root cause analysis on one specific problem, like rising TACoS or a launch that stalled at month three
- A phased roadmap that sequences fixes by impact instead of listing forty things at once
- Marketplace or category expansion planning, with margin modelling before you commit inventory
- Vendor selection support, meaning help writing the brief and reading agency pitches independently
- Oversight of an existing agency or internal manager, checking whether execution matches the plan
Most consulting runs as a fixed project or a light monthly advisory retainer. The engagement usually ends before the results show up, which is why brands who expected a performance lift come away feeling they paid for a document.
That limitation is real, and the agencies writing about this topic are right to raise it. A plan only pays off if somebody on your side has the hours and the skill to run it.
What an Amazon marketing agency actually does
An agency takes ongoing ownership of agreed parts of your account. Full service means very different things at different shops, and the difference lives in the scope document rather than the homepage.
What you are buying is continuity. Somebody watches the account on the days you do not, and answers for the result.
What sits inside a typical scope
- Amazon PPC Ads management across Sponsored Products, Brands, and Display, including bids, budget pacing, and negatives
- Listing work across titles, bullets, backend search terms, imagery, and A+ content
- Organic rank strategy run alongside paid rather than as a separate workstream
- Catalogue and account health, covering suppressions, policy issues, and Brand Registry problems
- Reporting on an agreed cadence, ideally with a written explanation of what moved and why
- Quarterly planning for seasonality, launches, and deal events
Agency margin comes from how many accounts each manager carries. The senior operator who won your business usually hands the account to someone holding fifteen or twenty others, and the strategy quietly flattens into a checklist. That is the structural problem, and no case study on a homepage will show it to you.
Ask how many accounts your manager handles and get the number in writing. It predicts quality of attention better than anything in the pitch deck. If you are still building a shortlist, this breakdown of Amazon Ads Management Services is a reasonable starting point.
Amazon consultant vs agency: side-by-side
Here is the whole comparison in one view. The rows that settle most decisions are engagement length, who implements, and what you can actually hold them to.
The cost row misleads people. A $6,000 project and a $6,000 month look comparable until you remember that only one of them includes somebody doing the work.
What each one actually costs in 2026
Almost nobody writing about this publishes numbers. Here are the three pricing models you will be quoted, and what each one quietly rewards.
The three agency pricing models
- Flat monthly retainer. Usually $2,500 to $12,000 depending on catalogue size and scope. Predictable, and it does not punish the agency for cutting your ad spend when cutting it is the right call.
- Percentage of ad spend. Typically 8% to 15%, often with a floor. The incentive problem is obvious. The agency earns more when you spend more, which is a bad arrangement on an account that needs spend discipline.
- Retainer plus performance. A lower base with a bonus tied to revenue or TACoS. Fairest on paper, but only if the metric is defined tightly. A revenue share alone pays them for branded search you were already winning.
What consultants charge
Expect $150 to $400 per hour, or $2,500 to $15,000 for a scoped project. The rate tracks whether the person has run accounts at your revenue level, not how many years the word consultant has been in their title.
Same problem, two routes. A $4M brand with climbing TACoS and a launch that stalled.
Consultant route: $8,000 for an audit and roadmap delivered in three weeks. Your existing marketplace manager executes it over the next quarter. Year one outlay is about $8,000 plus hours already on payroll.
Agency route: $6,500 a month on a twelve month term. Year one outlay is $78,000, execution included, and your internal manager gets handed back to merchandising and retail.
The gap is not the point. What matters is whether the internal person exists at all. Without one, that $8,000 buys a PDF.
Neither quote includes ad spend, creative production, or the four to six weeks either engagement takes to produce anything useful. Check current Amazon Ads Cost benchmarks before you budget the media side, because that number is usually larger than the fee.
When a consultant is the better call
Consulting fits when the bottleneck is knowing, not doing. Five situations make that true almost every time.
- You have already been through one agency and it did not work. Hiring a second before you know whether the strategy or the execution failed is how brands lose two years instead of one.
- You are moving onto Amazon from DTC or retail. The expensive mistakes happen in the first ninety days, in pricing, catalogue structure, and channel conflict, long before there is anything worth optimising.
- You have execution capacity and no direction. Someone is running campaigns competently while nobody is asking whether the product mix, price ladder, or launch order is right.
- You are facing one high-stakes decision. A category expansion, a price restructure, a move to Vendor Central, or an agency transition all carry twelve month consequences and deserve outside input once.
- You need help hiring. A consultant who does not want the retainer is the only person who will read three agency pitches honestly on your behalf.
All five assume somebody on your side does the work afterwards. If nobody will, you are paying for a document that ages badly.
When an agency is the better call
Agencies fit when the bottleneck is hours. Four signals make that clear enough to stop deliberating.
- Your catalogue outgrew one person. Past roughly 150 active ASINs or a few hundred campaigns, part-time management stops being a budget decision and becomes a revenue leak.
- The account needs daily attention it is not getting. Bids, competitor moves, suppressions, and stock positions all change faster than a weekly review cycle can answer.
- You want one person accountable for a number. Ownership split across three people who each have another job is how accounts drift for two quarters before anyone notices.
- Growth is the plan and hiring is not. A senior in-house Amazon manager costs more fully loaded than most retainers and takes three months to find.
This is also the point where the work changes shape. Guidance on running Amazon Ads for Scaling Brands looks nothing like the advice written for a seller with twelve SKUs, and a shortlist of Amazon Product Ads Management Companies is worth building before you take any sales calls.
All of it holds only if the strategy is already sound. An agency will execute a wrong plan very efficiently.
How each model fails
Pros and cons lists are everywhere on this keyword. Failure modes are more useful, because they tell you what to watch for in month three.
The pattern matters more than any single row. Consultants fail loudly and early, and you notice because nothing happened. Agencies fail quietly and late, because the activity continues the whole time the strategy is going stale.
Can you use both at the same time
Yes, and past roughly $5M in revenue it is often the strongest setup. It only works when the split is written down before either one starts.
The consultant owns what should happen and whether it did. The agency owns making it happen.
It costs more, and it adds a second relationship to manage. If the metrics are not agreed upfront, the two of them will spend your quarterly call explaining why the other one is the problem.
It also leaves the underlying issue untouched for most brands, which is that both models are priced by human hours.
What to demand in the first 90 days, whichever you pick
You do not have to get this perfectly right. You have to be able to tell within a quarter whether it is working, which means agreeing the checkpoints before you sign anything.
A missed checkpoint is not a reason to leave. It is a reason to ask what blocked it, in writing. Two missed in a row, with no explanation you can verify against your own Amazon Ads Dashboard, is the signal.
Contract terms worth fixing before you sign
- A 30 day notice period after any initial term, not 90
- Your named account manager and their account load written into the agreement
- You keep ownership of the ad account, the campaign structure, and every creative asset
- A documented handover if the relationship ends, including campaign logic and keyword rationale
Decision scorecard
Score each row zero to three. Add both columns. The higher total is your answer, and the size of the gap tells you how clear-cut it is.
A gap of six or more points is a clear answer. Anything closer usually means you need both, or that your real gap is the operating model rather than the type of vendor.
Factors to weigh before you commit
Whether you have anyone internally to receive the work
This decides more than budget does. A roadmap without an owner is a PDF, and a retainer without an internal counterpart drifts by month four.
How much of the problem is diagnosis
If you can already name the three things that need fixing and your team agrees, you are buying capacity. If leadership disagrees about what is wrong, you are buying judgment first.
The pricing model, not just the price
A percentage-of-spend deal quietly pays your agency to spend more of your money. A flat retainer does not. The difference rarely shows in month one, but it shapes every recommendation you get for the next twelve months.
Account load per manager
Ask the number and get it in writing. It predicts the quality of attention better than any case study on their site.
What survives the engagement ending
Ask what you keep. Campaign structure, keyword rationale, creative files, and documented decisions should all be yours, and most contracts stay silent on it unless you raise it.
The third option this comparison usually leaves out
The reason you have to choose at all is that both models sell human hours. Advice is expensive because senior time is expensive. Execution gets thin because junior time has to be spread across accounts.
Buying software instead does not solve it either. Amazon Ads Software gives your team better visibility and faster rule changes, but somebody still has to sit in front of it every day and decide what the data means.
When the execution layer runs continuously and the senior person stays on strategy, the trade goes away. In practice that means bids moving hourly instead of weekly, and a strategist reviewing decisions rather than making each one by hand.
Where Xneeti sits
Xneeti was built around that split. Native AI runs the account across ads, listings, and inventory, while a dedicated strategist owns the account and reviews what the AI does.
- Account managers carry half the load of the industry average, so the senior person who won the account is the one still running it in month nine
- N-gram analysis runs continuously across your search terms, adding negatives before the waste shows up in an ACoS report
- Sponsored Brands creative is produced in house, which removes the production bottleneck that stops most sellers running Amazon Video Ads at all
- Listings are updated for both A10 and Rufus, since Amazon's AI assistant now shapes what shoppers get shown
We are an Amazon Ads Verified Partner built by ex-Amazon and ex-Google teams, and accounts average a 50% reduction in TACoS.
If you are weighing quotes and want to see what the account looks like without the hour count baked into the price, book a demo and a strategist will walk through yours.
