Across the cited provider examples, advertised full-service Amazon agency pricing spans $5,000-$18,500 per month, while published enterprise tiers can exceed $25,000. The fee is only comparable after you normalize scope, incentives, and the work left with your team. We exclude ALFI from the external pricing comparison and state our fit later. Every synthesized range below is an estimate, not a quote.
Key Takeaways
- Cited provider examples advertise full-service management from $5,000-$18,500 per month, with $25,000+ published for enterprise complexity.
- A 12% ad-spend fee costs $9,000 per month on $75,000 of spend, before creative, catalog, or inventory work.
- A 4% revenue fee costs $20,000 per month on $500,000 in sales, whether that revenue is profitable or not.
- Compare 7 cost lines, including internal coordination and excluded work, before treating the retainer as the total price.
- At $1M+ in annual revenue, compare at least 2 complete operating models instead of buying the cheapest list of tasks.
What should a $1M+ Amazon brand budget for agency support?
Use $5,000-$15,000 per month as an initial planning scenario for full-service management, then move the estimate up or down based on catalog, marketplaces, creative output, ad spend, account health, and operating authority. A narrow PPC mandate can cost less. A large catalog across several countries with frequent creative production can cost more.
Public pricing supports a wide band. Seller Sage lists monthly retainers from $5,500 for brands at $500,000-$1.5 million in Amazon revenue to $18,500 for brands at $5 million-$20 million. BellaVix publishes $5,000-$10,000+ for full-service management. SupplyKick places full-service work for $2 million-$10 million brands at $7,500-$15,000 and enterprise work at $15,000-$25,000+.
Those are agency-published figures. They prove what those providers advertise, not a universal market average or delivery quality. The useful comparison is the observed span and the scope attached to each price.
| Brand situation | 2026 planning estimate | What should be included |
|---|---|---|
| $1M-$2M, smaller catalog, one marketplace | $5,000-$9,000/month | PPC, listings, catalog health, reporting, planning, and named accountability |
| $2M-$5M, wider catalog or heavier ad spend | $7,500-$13,000/month | Full account management, creative cadence, forecasting, pricing input, and weekly operating decisions |
| $5M-$10M, complex catalog or several marketplaces | $10,000-$18,500/month | Senior team, connected operations, deeper creative, inventory planning, and executive reporting |
| Enterprise or unusually complex mandate | $15,000-$25,000+/month | Multi-marketplace team, high creative volume, compliance, DSP, and custom reporting |
These are labeled estimates derived from current advertised ranges. They are not ALFI prices and should not replace a scoped proposal.
Revenue alone does not price the work. A $2 million brand with 8 stable ASINs may require less operating effort than a $1.2 million brand with 180 ASINs, frequent stockouts, catalog errors, and two marketplaces. Ask the agency to show which facts moved your quote.
Which Amazon agency pricing model is best?
A flat retainer is usually the cleanest base for an established brand, provided the scope and accountability are explicit. It keeps the agency's fee from rising automatically every time ad spend rises. A performance component can work, but only when the baseline, profit definition, exclusions, and agency-controlled actions are written down.
| Model | How the fee moves | Strength | Main risk |
|---|---|---|---|
| Flat retainer | Fixed monthly amount | Predictable and easy to budget | A vague scope can let effort drift without clear accountability |
| Percentage of ad spend | 8%-20% of spend in the cited guides | Scales with PPC workload | The agency earns more when spend rises, even if marginal spend loses money |
| Percentage of revenue | 3%-10% in the cited agency guide | Simple top-line alignment | Rewards revenue without protecting margin, cash, or inventory |
| Hybrid | Base retainer plus a smaller variable fee | Covers labor and can reward upside | Complex baselines can make the "performance" fee hard to audit |
| Performance fee | Bonus tied to a defined result | Can focus both teams on one outcome | Weak baselines or control rules can make the fee difficult to audit or attribute |
For PPC-only work, Helium 10 reports 8%-15% of ad spend, while Levanta reports 10%-20%. Both have commercial interests in the agency-or-software decision, so treat the ranges as directional. They still show why percentage fees need a worked example.
Suppose a brand does $500,000 per month in Amazon sales and spends $75,000 on ads. A 12% ad-spend fee is $9,000 per month. A 4% revenue fee is $20,000. A $5,000 retainer plus 5% of ad spend is $8,750. None of those numbers tells you whether the agency owns listings, creative, catalog, inventory planning, pricing, reviews, account health, or profit reporting.
ROAS is not a fee model. If the variable payment rewards revenue or ad volume while your contribution profit falls, the contract is paying for the wrong outcome.
How should you compare a $1,500 fee with a $6,000 fee?
Net the fee difference before claiming a saving. Here is a hypothetical example where sales, product costs, Amazon fees, returns, and discounts stay unchanged. The brand produces $80,000 in contribution before ads and agency fees. Provider A charges $1,500 and spends $30,000, leaving $48,500. Provider B charges $6,000 and reduces unproductive spend by $6,000, leaving $50,000.
Provider B improved contribution by $1,500, not $6,000. The spend reduction was $6,000, but the additional agency fee was $4,500. If sales, conversion, or organic demand falls after the cuts, the result could be worse. If contribution rises, the value could be higher. The proposal must state which assumptions will be measured.
What is the profit-first contribution test?
Start with gross Amazon sales. Subtract discounts, returns, landed product cost, Amazon referral and fulfillment fees, ad spend, the agency fee, and other variable costs you can assign reliably. Compare the resulting contribution by SKU, month, and scenario. Do not credit the agency with all channel revenue or all account growth.
For a variable fee, define the baseline before work starts. State how price changes, stockouts, promotions, seasonality, new products, and organic sales will be handled. Pay for improvement the agency can influence, after the cost of producing that improvement. Otherwise, a performance clause can reward top-line movement while cash and contribution deteriorate.
How do you calculate the total cost of an Amazon agency?
Use 7 lines, not one. The retainer is only the first line of the total-cost model.
- Contracted agency fee. Include the retainer, variable fee, setup charge, minimums, and any annual increase.
- Excluded delivery. Price creative, photography, video, storefront work, DSP, launches, international markets, and emergency catalog work that sit outside the agreement.
- Internal coordination. Multiply the monthly hours spent briefing, chasing, reconciling reports, and moving information between vendors by a realistic loaded hourly cost.
- Tool duplication. Add software the agency requires you to keep even when similar capability is included elsewhere.
- Delayed-decision exposure. Track the sales, margin, or inventory consequence when no one has authority to resolve a pricing, stock, creative, or account-health issue.
- Margin leakage. Measure discounting, ad spend, fees, returns, storage, and product-level contribution rather than assuming higher sales created value.
- Switching and exit cost. Include notice periods, access cleanup, campaign documentation, creative files, reporting history, and the time needed to transfer context.
Do not invent a delay number to make a proposal look bad. Measure it. If a stockout lasted 9 days because inventory data sat between three teams, use the affected ASINs, lost units, and contribution per unit. If the agency could not control that decision, assign the cost to the operating design, not automatically to the agency.
Here is a hypothetical comparison for a $6 million annual brand. Proposal A charges $8,000 per month and leaves 15 internal coordination hours at an assumed loaded cost of $100 per hour. Its visible monthly cost is $9,500 before excluded projects. Proposal B charges $5,000 for PPC, while separate catalog and creative support cost $3,000 and coordination consumes 35 hours. Its visible monthly cost is $11,500 before delay or margin leakage.
The cheaper retainer is not the cheaper operating model. Full service is not a longer menu. It is the condition for accountability when the provider is expected to own the connected outcome.
What should you ask before comparing two proposals?
Ask for the operating design behind the number. A polished proposal can still leave the hard work scattered across your team.
What is included every month?
Request a scope matrix with recurring work, project work, response times, owners, and exclusions. "Listings included" is not enough. Does that mean metadata edits, new copy, A+ Content, image briefs, testing, suppressed-listing recovery, and variation fixes, or only two updates per month?
Who owns each connected decision?
Map advertising, listings, creative, catalog, inventory, pricing, reviews, account health, forecasting, unit economics, and reporting. If three vendors can recommend action but nobody can decide, you are buying commentary without accountability.
Who will still be on the account after the sale?
Get the names and roles of the people responsible for strategy, execution, and escalation. Ask what happens during leave and how context survives a team change. If the assigned roles differ from the roles scoped in the proposal, the value of the same fee changes.
How does the fee change as we grow?
Run the contract at current sales, your 12-month plan, and a high-season month. A percentage that looks modest today can become the most expensive line in the model at scale. Ask about caps, floors, step-downs, and which revenue or spend base the percentage uses.
How is profit defined and reported?
Require a product-level view of sales, landed cost, Amazon fees, ad spend, discounts, returns, and other variable costs the team can reliably access. The agency does not need to own your finance function, but it should understand the economic boundary for each SKU.
What happens in the first 60 days?
Tie any setup fee to outputs: access audit, campaign map, catalog risk list, contribution inputs, reporting baseline, and a prioritized operating plan. Marknology publishes a $1,000-$5,000 setup range, but the right amount depends on the actual deliverables.
What are the exit terms?
Confirm notice, campaign ownership, raw data access, creative-file ownership, documentation, and handoff support. If you are already seeing continuity or responsiveness problems, use our guide on when to replace an Amazon agency before signing another agreement.
What proof can we inspect?
Ask for a sample report, a real meeting agenda, role definitions, and an anonymized operating plan. Case studies can show a reported outcome. They do not prove that your assigned team, scope, or economics will match it. Our agency selection guide gives the full diligence sequence.
Where does ALFI fit, and where does it not?
We are built for brands generating $1M+ a year on Amazon, plus $1M+ DTC brands ready to make Amazon a serious second engine. We cap the roster at 18 clients so senior judgment stays close to the work. Naeela leads strategy, review, accountability, and delivery conversations, while seasoned senior operators own the day-to-day work.
Our engagement boundary is full-service Amazon ownership. We do not accept PPC-only work because advertising, conversion, catalog, inventory, price, reviews, account health, and unit economics keep changing one another. We will not accept responsibility for profit while controlling one disconnected lever.
That makes ALFI a poor fit for early-stage sellers, buyers choosing mainly on the lowest fee, teams wanting a large rotating bench, or brands seeking isolated task execution. A specialist may be the honest better choice when your need is narrow, your internal team already owns the connected operation, and decision rights are clear.
The responsibility runs both ways. ALFI owes senior judgment, candor, continuity, and the willingness to refuse a bad decision. The client owes economic visibility, operational truth, access, and the willingness to act on hard recommendations. Without both, the fee cannot buy accountability.
If that operating model matches what your brand needs, review ALFI's full-service Amazon model. We can review the proposed fee as a share of contribution profit and identify which connected responsibilities are still unowned.

What to do this week
- Put every proposal into one scope matrix with the same 7 cost lines.
- Calculate percentage fees at current sales, planned sales, and peak-month ad spend.
- Price the internal hours and separate vendors each proposal still requires.
- Ask for the named team, decision rights, sample report, and first 60-day outputs.
- Mark every estimate, missing input, exclusion, cap, floor, and exit term.
- Compare the total against contribution profit, not revenue alone.
- Choose the operating model that can own the consequence, not the lowest retainer.
How much does a full-service Amazon agency cost per month?
Across the cited 2026 provider examples, advertised full-service prices span $5,000-$18,500 per month. Published enterprise tiers can exceed $25,000. These are not quotes or a market average. Catalog size, ad spend, creative volume, account health, marketplaces, and the authority included in scope can move the final fee.
Is a percentage of ad spend fair for Amazon PPC management?
It can be fair for a narrow PPC mandate when the percentage, floor, cap, and included work are clear. At 12%, $75,000 in monthly ad spend creates a $9,000 fee. The risk is automatic fee growth even when the next dollar of spend produces weak contribution profit.
Should a $1 million Amazon brand hire a full-service agency?
Only if the brand has enough catalog, advertising, inventory, and operating complexity to justify the fee. A simple catalog with a capable internal owner may need a specialist instead. A fragmented brand losing time across several vendors may benefit from one team with connected authority and clear accountability.
Are setup fees normal for Amazon agencies?
Yes, when the fee funds defined onboarding work. Ask for a written list covering access, account audit, campaign map, catalog risks, contribution inputs, reporting baseline, and the first 60-day plan. A setup charge without inspectable deliverables is simply an extra fee, regardless of whether the amount looks normal.
How do I know whether an Amazon agency is overpriced?
Do not judge the retainer alone. Add excluded services, internal coordination, duplicated tools, variable fees, delay exposure, margin leakage, and exit costs. Then compare that total with product-level contribution profit and the authority the agency receives. A higher fee can be cheaper when it removes fragmented work and protects decisions.
