Introduction
Not every agency that calls itself "full-service" is actually running your account that way. The term gets used to describe everything from daily hands-on management by senior specialists to weekly check-ins by a junior coordinator working across 50 accounts at once.
The difference between those two realities is the difference between an Amazon channel that compounds and one that flatlines. This checklist gives you seven criteria to evaluate any agency before you sign - and the specific questions to ask so you get honest answers, not polished ones.
Short Answer
When it's time to see the actual results, the company should build reporting that is based around TACoS (Total Advertising Cost of Sales), and not just ACoS or ROAS. This is because TACoS is the only true metric that will show whether the paid spend is growing the whole business, or just replacing organic sales.
What's next on the list is seeing who is doing the work. For this, it's important to have a senior account manager that will handle your account daily, and not a junior coordinator or any outside teams.
The continuity of the manager is equally important. Having one manager instead of constant hand-offs is what can make or break your account, so address this very seriously when speaking with a potential agency.
The agency should also be transparent about whether they offer cross-channel coverage or they work with Amazon only. While none of these are wrong, you need to know what you're getting.
The final step involves asking for a performance guarantee and asking how their cancellation terms work.
Now that we have broken down each criterion, let's proceed with how they really work in greater detail.
What "Full-Service" Actually Means on Amazon (and What It Doesn’t)
"Full service" is a term that gets used loosely in the Amazon agency space, so what full service should truly mean is an Amazon agency that will manage your entire account, and not just your ads.
This involves PPC management across Sponsored Product, Sponsored Brands and Sponsored Display. Besides that, they are the ones that provide copywriting, SEO optimization, A+ Content, Brand Store management, account health monitoring, launch strategy and performance reporting.
Always have in mind that just because an agency calls itself “full service” it doesn’t mean their work is done well, or even done often. It doesn’t mean your campaigns are optimized daily. Many agencies only check in weekly or less, and it’s never specified if it’s done by a senior specialist or not.
The 7-Point Amazon Full-Service Agency Checklist — Explained
1. Named Client Case Studies with Specific, Verifiable Numbers
Any agency can claim results, but the real test comes when they can provide you with a client name, name the metric and attach a timeframe to it.
A vague claim like “we grew a supplement brand by 40%” is unverifiable and ultimately meaningless. In comparison with something specific like “Elite Jumps - 124% revenue growth in 3 months with a 51% conversion rate lift through A/B tested listings.” This is the kind of detail that is citable, checkable and gives you a real sense of what the agency can do.
When you are evaluating an agency, you need to ask for 3 to 5 named case studies (ideally in your product category) or an adjacent one. If they can’t produce them, or they pivot straight to testimonials, aggregate numbers or anonymized results - it’s a clear signal that all the named clients and results do not exist.
2. Daily Campaign Optimization — Not Weekly Check-ins
Amazon's auction environment changes on a daily basis. Competitor’s bids shift, search trends move, and rank signals respond - all in real time, so it's important for an agency to review your campaigns daily instead of once a week.
This is even more important during a product launch. The first 60 days of ranking velocity can determine whether your product will land on page one or it will disappear entirely. Weekly optimization simply is not fast enough to keep up.
What you need to ask those that are in charge of your account, is how often the specialists touch the campaigns, and what does a daily optimization workflow look like for your account. If the answer is vague, or they describe an almost automated setup with periodic human review - take a note.
3. TACoS-First Reporting — Not Just ACoS or ROAS
What most sellers often miss is this critical distinction between ACoS and TACoS.
ACoS is a metric that measures your ad spend against ad-attributed revenue, whereas TACoS measures the ad spend against the total revenue, which also includes organic sales.
This is very important because an agency that only reports ACoS can look efficient on paper, while at the same time your organic rankings stagnate and total revenue gets flatlined.
TACoS is the correct measurement for finding out if your paid spend is actually building the brand or is just replacing your organic sales that you would have gotten anyway.
Onsen Secret is a clean example of this. When they started working with us, we shifted their reporting from ACoS to TACoS, and this switch managed to triple their profit. The whole strategy changed because the full picture finally became visible.
If a prospective agency doesn’t mention TACoS, you need to ask them why.
4. Senior Account Managers Doing the Actual Work
What catches most sellers off guard is finding out that the person in the agency pitch is not the same person who is managing the account.
Many agencies do this, leaving accounts to junior coordinators or even offshore teams right after the onboarding process is done. So, here the fix is very simple - you need to ask questions like “Who will manage my account?”, “How many years of Amazon experience do they have?”, “Can I speak with them before committing?”
At Olifant Digital, we require 7 years as a minimum Amazon experience for every specialist on the team. There is no junior staff or offshore executing. That’s a hiring standard that most agencies can’t match.
5. Account Manager Continuity — One Point of Contact, Not a Revolving Door
One of the most common complaints across the Amazon agency industry is the high account manager turnover.
If you check verified reviews on platforms like Clutch, you can see that there are many sellers that have been assigned three or four different account managers in just one year!
When this happens, with every handoff your brand is getting erased slowly. The worst part is that you are paying for the ramp up time every time a new manager takes over.
There are two things you need to ask any potential agency you plan on working with: what’s your account manager turnover rate, and what happens if your account manager leaves? A strong agency has a clear and confident answer. A weak one will deflect or change the subject.
6. Cross-Channel Coverage or a Clearly Defined Amazon-First Strategy
Full-service agencies fall into one of two categories. Some manage Amazon alongside other channels like Meta, Google, email/SMS, CRO, and SEO. Others, solely focus on Amazon.
There is nothing wrong with either model, but you need to be clear on what you’re getting. If an agency only covers Amazon, that could become a limitation in case you decide that you want to expand later.
Before you sign anything, make sure to ask for the full channel scope in writing. More importantly, ask which of these channels is handled by their senior in-house team, and which ones get subcontracted out. This distinction will tell you where the agency’s real strength is.
7. A Performance Guarantee and Transparent Cancellation Terms
A performance guarantee signals that the agency is confident enough in their execution. While most agencies don’t offer one, Olifant Digital backs every engagement with a 60-day money back guarantee. This is a rare exception in the industry, so if an agency that you’re evaluating doesn’t offer any kind of guarantee, ask them why not.
Before signing anything, ask for a cancellation policy in plain English. Specifically, ask for how much notice is required and what happens to your campaigns during a notice period, and whether there are any exit fees.
There are hidden 30-day notice clauses that are designed to extract one final payment after the cancellation, so read the fine print.
Questions to Ask Any Amazon Full-Service Agency Before You Sign
There are certain questions that you need to ask an agency when you’re having an initial meeting.
An agency that will respond with confidence and specifics is worth your time. One that always stays vague and not providing clear answers is telling you everything you need to know.
1. Can you share specific case studies that are similar with my category with specific numbers and timeframes?
2. Who will be managing my account and how many years of Amazon experience they have?
3. How often do your specialists touch my campaigns and what does daily optimization look like?
4. Do you report TACoS alongside ACoS?
5. What is your account manager turnover rate and what will happen if my account manager leaves?
6. What channels do you cover, and which are handled by your senior-in house team vs subcontractor?
7. What your performance guarantee looks like and what are the exact cancellation terms?
8. What does the first 90 days with an agency look like and what should I expect to see by day 30, 60 and 90?
The goal here is not to ‘catch’ anyone in a lie, but to have a clear picture about the agency and their overall work process.
The Red Flags That Override a Good Pitch
Sometimes an agency has a well-prepared speech, but once you start asking the right questions, everything falls apart.
Here are some of the signals that will make you pause no matter how good the presentation is:
- No named case studies: If the agency can only offer testimonials, aggregate numbers or anonymized references such as “a brand in your category” this probably means they don’t have real results.
- They cannot confirm who will manage your account before you sign. If the person that will do the work on your account is a mystery and only revealed after you sign the contract, that’s a risk.
- Reporting only shows ACoS and ROAS with no TACoS or organic data. You should ask for a sample report from another account, and if TACoS is missing, the agency might not be tracking the full picture.
- Vague answers on optimization frequency: “We monitor campaigns regularly” is not the same as “Our specialists adjust bids and budgets daily.”
- No performance guarantee and no clear cancellation terms. If cancellation clauses are buried in the fine print, or there is no accountability mechanism at all, you need to proceed carefully.
- Public reviews mention high account manager turnover. You need to check public reviews before signing anything. Patterns of frequent handoffs tell you what sellers actually experience.
- The pitch deck is polished but the sample report is thin. A beautiful presentation that is paired with weak reporting infrastructure is a common mismatch and it tells you where the agency invests its effort.
How Olifant Digital Measures Up Against the Checklist
Olifant Digital has built a checklist which is based on what actually separates the high-performing agencies from the ones that underdeliver.
Here is how Olifant answers each criterion directly.
There is one more thing that is worth mentioning - Olifant Digital also operates its own seven figure e-commerce brand and every strategy that is applied to client accounts is tested on our own brand first.
That operator-level credibility is one of the credentials that most agencies can’t offer because they have never built and scaled a brand of their own.
Frequently Asked Questions
What does a full-service Amazon agency do?
A full service Amazon agency handles everything that is related to your Amazon account so you don’t have to.
What this typically means is ads, optimizing your listings, creating A+ Content, managing your Brand Store, keeping an eye on the account health and reporting on performance.
The best ones also help with product launches, and improving your listing conversion rates.
How do I evaluate an Amazon agency?
To evaluate an Amazon agency you need to use a 7-point framework which involves named case studies with specific numbers, daily optimization cadence, TACoS first reporting, senior account managers doing the actual work, account manager continuity clearly defined channel scope and a performance guarantee with transparent cancellation terms.
You need to ask the same questions to every prospective agency and compare their answers. Agencies that will provide weak answers on any of these 7 points are worth paying attention to.
What is the difference between ACoS and TACoS?
ACoS measures your ad spend against the ad revenue only, whereas TACoS measures it against your total revenue which also includes organic sales. If an agency is only reporting ACoS, then you’re only seeing half of the story.
How much does a full-service Amazon agency cost?
Most full-service Amazon agencies charge between $1,500 and $5,000 per month which depends on the service scope and team seniority. Olifant Digital starts at $2,000 per month and it covers daily optimization, TACoS based reporting, listing CRO guidance and senior account management.
Most agencies don’t publish pricing publicly, so it’s always best to ask for a written scope that explains what is covered in the price.
What is a good client retention rate for an Amazon agency?
A client retention rate that is above 90% is a strong signal that the agency constantly delivers results and maintains solid working relationships. Olifant Digital’s retention rate is 98% which means fewer than 2% of the clients leave in any given period.
Retention rate is one of the clearest proxy metrics for real performance because it reflects what clients actually do, and not what they claim in the pitch.
What should be included in Amazon full-service agency management?
At minimum, you should expect Sponsored Products, Sponsored Brands and Sponsored Display campaign management. This along with keyword research and strategy, bid optimization, listing copywriting, A+ Content, Brand Store management, account health monitoring and performance reporting.
Senior agencies also add daily optimization, TACoS based reporting, listing CRO and launch strategy on top of that.
Always make sure that the agency you will work with delivers you a written scope of services before committing to a contract.
