Hiring an Amazon agency means engaging a specialist firm to manage your Amazon channel: listings, advertising, inventory, creative, and strategy. Done well, it's a structured buying decision, not a vendor search. This guide covers every stage: pre-hire diagnostics, scope definition, the RFP process, contract terms, and your first 90 days.
Use the "Start Here" checklist at the top, then read the sections that match your stage. Every section is self-contained, so jump freely.
These terms come up throughout any serious Amazon agency conversation. Understanding them before you start talks will save you time and prevent misunderstandings.
Retainer
A fixed monthly fee for a defined scope of services. Offers budget predictability regardless of your sales performance.
Percentage-of-ad-spend model
The agency's fee is calculated as a percentage of your monthly Amazon ad budget, typically 10 to 20 percent. Fees scale automatically as your ad spend grows.
Commission or percentage-of-revenue model
The agency earns a cut of your total Amazon revenue, usually 3 to 10 percent. Incentives are closely aligned but costs can escalate quickly at high volumes.
Hybrid model
A lower base retainer combined with a performance bonus or revenue share. Popular with brands that want cost predictability and incentive alignment at the same time.
A+ Content
Amazon's enhanced brand content module that replaces the standard product description with rich images, comparison charts, and brand storytelling. Available to brand-registered sellers.
TACoS (Total Advertising Cost of Sale)
Ad spend divided by total revenue (organic plus paid). TACoS is a more complete performance signal than ACoS alone because it shows how advertising affects the whole business.
DSP (Demand-Side Platform)
Amazon's programmatic advertising platform. It lets brands serve display and video ads on Amazon and across the web, including to shoppers who've viewed competitor products.
Brand Registry
Amazon's program for trademark owners. It unlocks A+ Content, brand analytics, and stronger tools to remove counterfeit or unauthorized listings.
Not every brand is ready for an agency, and signing with one before you're ready is an expensive mistake. The honest answer depends on three things: your revenue stage, your internal capability, and the complexity of your Amazon catalog.
Full-service agency fees typically start at $3,500 per month for growing brands, according to SupplyKick's 2026 pricing guide. If your Amazon monthly revenue is under $15,000, you'll struggle to see a return on that investment.
Agency fees should represent no more than 15 to 20 percent of your Amazon revenue. Below that threshold, a part-time consultant or a self-managed ad tool usually makes more sense.
Once you're generating $30,000 or more per month on Amazon, the ROI math on a good agency almost always works. At that stage, advertising complexity, listing quality, and inventory coordination compound faster than one person can manage.
Most brands don't hire an agency because they lack effort. They hire one because they lack specific expertise: advanced PPC architecture, A+ Content production, demand forecasting, or Brand Registry enforcement.
Before you reach out to any agency, write down every Amazon task your team handles. Mark each one as "confident", "struggling", or "not doing it". The gaps in that list are your scope of work.
If you're "struggling" in three or more Amazon disciplines at once, a full-service agency will almost certainly outperform a patchwork of freelancers. Coordination overhead across multiple specialists is a hidden cost most brands undercount.
Agencies work best when your product-market fit is proven and your supply chain is stable. If you're pre-launch, testing price points, or regularly out of stock, fix those problems first. No agency can rank a weak product or run effective ads on listings that stock out regularly.
For a deeper comparison of agency versus in-house options, see Amazon Agency vs In-House Team: Which One Wins for a Growing Brand?
A full-service Amazon agency covers the full channel stack: listings, advertising, inventory, creative, brand protection, customer service, and performance reporting. In practice, agencies vary widely in what they own versus advise on. The details live in the scope-of-work document.
Listing optimization covers keyword research, title and bullet copywriting, product descriptions, A+ Content, and your brand store. This is table-stakes work. Every serious agency does it, but quality varies widely.
Advertising management includes Sponsored Products, Sponsored Brands, Sponsored Display, and DSP. A strong agency builds a campaign architecture that targets the full funnel, not just a handful of broad match auto campaigns. Look for agencies that report on TACoS, not just ACoS, because TACoS tells you whether ads are actually growing your business.
Inventory and order management means maintaining FBA stock levels, submitting reimbursement claims for lost inventory, and flagging stranded listings. This service is often underrated but directly affects revenue continuity.
Creative production means photography, infographics, video, and design for A+ Content and brand store. High-quality creative is one of the highest-ROI investments on Amazon, yet many brands leave it as an afterthought.
Brand protection and registry involves enforcing your IP rights, removing unauthorized resellers, and managing hijacked listings. It's reactive work but important for protecting the equity you're building.

Most agencies have a primary strength: advertising, listing content, or operations. Ask every agency you evaluate where most of their team's hours go. That tells you more about their real capability than a services page does.
Scope definition is the most skipped step in the agency hiring process. Brands jump straight to "who's the best agency?" without first deciding what they want the agency to own.
That's backwards. Your scope document drives the RFP, which drives the proposal, which drives the contract.
Assign each Amazon service area to one of three columns: "agency owns", "agency advises, we execute", or "we own fully". Be specific: "Advertising" is not a scope item. "Build and manage all Sponsored Products campaigns, report weekly on TACoS" is.
Your scope matrix also tells you what to measure. Every item the agency "owns" needs a KPI and a reporting frequency in the contract. If it's not measurable, don't assign it.
Initial listing rewrites, A+ Content builds, and brand store creation are one-time projects. Ongoing advertising management, inventory monitoring, and reporting are recurring services. Price them separately in your RFP; mixing them into one monthly fee makes it hard to audit value later.
Agencies work faster when you arrive with high-resolution product photography, accurate inventory data, and a completed Brand Registry application. If you're missing any of these, factor the time and cost into your onboarding timeline.
We've seen brands delay launch by six weeks because they didn't have print-ready packaging images for A+ Content. Don't be that brand.
An RFP (request for proposal) is a structured document you send to shortlisted agencies. It tells them exactly what you need and asks them to respond with a specific plan, team, and price. A good RFP takes about two hours to write and saves you weeks of disorganized back-and-forth.
Aim for three to five agencies on your shortlist. More than five creates evaluation fatigue; fewer than three doesn't give you a real comparison. Use the 7 Best Amazon Agencies in 2026: A Buyer's Guide as a starting point.
Narrow the list by sector fit, revenue stage alignment, and whether they're transparent about pricing on their website.
Your RFP should include: a one-paragraph brand description, your scope matrix, target KPIs, a budget range, and specific questions. Don't leave the budget range blank. Agencies that know your budget write sharper proposals and waste less of your time.
The key questions to include in any Amazon agency RFP:
For the full list of interview questions, see 15 Questions to Ask Before Hiring an Amazon Agency.
Most reputable agencies will offer a free account audit as part of the sales process. Take them up on it. A quality audit shows how the agency thinks and whether their findings match your own assessment.
A generic audit says "your listings need better keywords." A specific one names the ASIN and the missing search terms. Generic findings signal shallow analysis.
Ask the agency to present the audit results live rather than sending a PDF. Watching how they explain findings tells you a great deal about how they'll communicate throughout the engagement. An agency that can't explain their audit clearly won't be easier to work with once you've signed.
Once proposals arrive, evaluate them against a consistent scorecard rather than reacting to the one that "sounds best". Gut feel favors the most persuasive salesperson, not the most capable agency. A scorecard keeps you objective.

A proposal that promises guaranteed rankings or specific revenue outcomes is a red flag. Amazon's algorithm is not guaranteed by any agency. An agency that says otherwise is either naive or misleading you.
Watch for proposals that are heavy on agency credentials and light on your specific account. A template proposal with your logo pasted in tells you exactly how much customized thinking you'll get after you sign. For a full list of warning signs, see 9 Red Flags to Watch For When Hiring an Amazon Agency.
Also look critically at who is presenting versus who will actually work on your account. Sales teams and account management teams are different. Ask directly: "Will the person I'm speaking with now be involved in my account day to day?"
Three pricing structures dominate the Amazon agency market: flat retainer, percentage-based (of ad spend or revenue), and hybrid. Each has a different risk-and-reward profile depending on your revenue stage and growth goals.
A flat retainer is the simplest structure: you pay a fixed fee every month for a defined scope. Per Marknology's 2026 pricing breakdown, full-service retainers for $250K–$3M brands run $3,500 to $7,500 per month. Enterprise brands at $10M or more can expect $10,000 to $25,000 per month.
Retainers work best when you want comprehensive ongoing management and you'd rather have a predictable monthly cost than a variable one. The risk is that the agency's incentive is to retain the contract, not necessarily to grow your revenue. Protect yourself by tying scope reviews and renewals to performance benchmarks.
Ad-focused agencies charge 10 to 20 percent of monthly ad spend, with a $2,000 floor, per SalesDuo's 2026 guide. This model scales with your ad investment and ties the agency's fee to the work they're doing.
The downside: as your ad budget grows, so does the fee, even if the incremental management complexity doesn't change proportionally. Set a fee cap or review points at key budget thresholds in the contract.
A revenue commission model, typically 3 to 10 percent of Amazon sales, ties agency fees to your channel growth. It looks attractive because the agency only earns more when you do. At scale it gets costly: a brand doing $500K per month at 5 percent pays $25,000 monthly in fees.
This model also raises attribution questions. If organic rank improves from listing work done six months ago, does the agency deserve a commission on every organic sale indefinitely? Clarify attribution rules in writing before signing any commission deal.
Hybrid pricing pairs a base retainer ($2,000 to $5,000 per month) with a performance incentive, per ALFI's 2026 pricing guide. Most brands with established catalogs prefer this structure. The base covers core costs; the bonus rewards outperformance.
Full-service retainers for mid-market brands ($250K–$3M) run $3,500 to $7,500 per month in 2026, per SupplyKick. Most agencies also charge a one-time onboarding fee of $1,000 to $5,000. That covers audits, campaign builds, and initial creative work.
The contract is where good intentions become binding commitments. Most agencies present their standard contract as "what everyone signs." Treat it as an opening position, not a final offer.
A few well-negotiated clauses protect you far more than a longer services list.
Six months is the most common minimum commitment for Amazon agencies. Amazon's ranking algorithm, advertising learning phases, and listing improvement cycles all require time. A six-month minimum is reasonable; be skeptical of any 12-month lock-in with no performance escape hatch.
If you sign a 12-month contract, negotiate structured reviews at month three and month six. If KPIs slip, you need a defined escalation path: raise concerns, get a remediation plan, and exit without penalty if it fails.
Every Amazon agency contract should include a performance-based exit clause. It defines specific KPI thresholds, such as a minimum ROAS or maximum ACoS. Miss those thresholds over a 60-to-90-day review window and you can terminate without a cancellation fee.
Confirm in writing that all creative assets produced during the engagement (photography, A+ Content, brand store designs, ad creative) belong to you. Some agency contracts contain clauses asserting joint ownership or the right to use client assets in their own marketing without consent. Review this section carefully.
You should maintain admin access to your Seller Central account at all times. Never transfer account ownership to an agency; grant editor or manager-level access only.
Your account, your data, your access. If an agency asks you to transfer ownership or won't work under a managed-access model, that's a hard stop.
Standard notice periods for termination range from 30 to 60 days. The agency should deliver a complete handoff package: campaign structures, keyword lists, creative files, and reporting templates.
Ask for offboarding deliverables to be listed in the contract, not just verbally agreed. We've seen offboarding disagreements cause real operational disruption for brands that didn't get this in writing.
Include a clause capping annual fee increases at five to ten percent per year. Also define what happens when work falls outside the original scope. A clear change-order process prevents the most common source of fee disputes.
Onboarding is where most agency relationships either build momentum or stall. A structured onboarding process protects both sides. The agency gets the access and context they need; you get confidence that execution will follow the agreed strategy.
Most agencies will send an onboarding intake form within the first 48 hours. You'll need to provide: Seller Central access, brand guidelines, creative assets, sales history, and prior ad data. The faster you complete intake, the faster the agency can audit your account.
Expect to spend five to ten hours per week in month one on meetings, approvals, and asset delivery. That front-loading reduces back-and-forth later in the engagement.
A credible agency should complete the initial account audit within the first ten business days. The audit should cover: listing health, advertising account structure, inventory history, and brand registry status. You should receive a written audit report, not just a verbal summary on a call.
At AmpliSell, we complete a full listing, advertising, and operations audit in the first two weeks. We present findings with a prioritized action plan before any execution begins. The audit phase often surfaces quick wins that pay for the first month of fees almost immediately.
Once the audit is complete, a structured agency runs a 90-day sprint with clear phases:
According to SupplyKick's first-90-days guide, expect five to ten hours per week in month one. That drops to two to three hours per week by month three as the agency gains full operational context.
The biggest predictor of success isn't the agency's track record , it's the quality of your onboarding. Brands that complete intake thoroughly and engage in strategy reviews consistently hit their 90-day goals. This pattern holds regardless of category or revenue size.
The first 90 days set the tone for the entire engagement. Set realistic expectations going in and you'll avoid the most common source of early friction: misaligned timelines.
Month one is almost entirely setup and strategy. New listings take one to four weeks to index for keywords. New ad campaigns enter a learning phase while Amazon gathers data to optimize delivery.
You should see activity (rewrites live, campaigns launching, creative delivered) but not significant revenue movement yet. Brands that expect a revenue lift in week two almost always end up disappointed.
By month two, look for early signals: CTR improvements on relaunched listings, better ad relevance scores, and first organic rank movements. These indicate the strategy is working, even if top-line revenue hasn't shifted yet. Ask your agency to surface these leading indicators explicitly in month-two reports.
Month three is when campaigns have exited learning phases and listing changes have had time to affect organic rank. This is your first chance to make data-driven decisions: scaling what's working, cutting what isn't, and planning months four through twelve.
Month three is also when your first formal performance review should happen. Compare actual results to the KPIs agreed at contract signing. If trajectory is off, have an honest conversation about why and what changes the agency will make.
To calibrate what's realistic in 90 days, consider results from AmpliSell clients. Maelove grew from zero to $3.6 million in Amazon revenue in 11 months. Elgin USA reached $300,000 per month within three months.
Then I Met You saw a 42 percent revenue increase in two months.
Condition 1, an outdoor and tactical brand, posted 152 percent revenue growth in six months. These aren't typical results; they reflect brands that arrived with strong products and completed onboarding thoroughly. But they show what's possible when both sides do their part.
After the first 90 days, performance evaluation shifts from leading indicators to business outcomes. You need a reporting framework that shows channel health and agency contribution clearly, without hours inside Seller Central each week.
For advertising performance, TACoS (Total Advertising Cost of Sale) is the most important single metric. A falling TACoS alongside rising total revenue means advertising is working efficiently and organic rank is improving. Rising TACoS alongside flat revenue means you're spending more for the same output, a clear warning sign.
For listing health, track conversion rate and session-to-unit ratio over time. A rewrite that doesn't lift conversion within 60 to 90 days either failed or faces barriers your agency should address.
For overall account health, track inventory health score, stranded listing rate, and customer service response time if your agency handles that function. These operational metrics don't show up in revenue reports but compound significantly over a year.
Any full-service engagement should include a formal quarterly business review (QBR). The QBR should cover: results versus KPI targets, ROI by service area, key learnings, and a roadmap for the next quarter.
If your agency doesn't bring a QBR to you, ask for one. An agency that doesn't proactively review performance data doesn't have a culture of accountability.
Renewal decisions should be made on data, not on relationship comfort. Before any renewal, run your own performance analysis: has Amazon revenue grown faster than your total agency spend? Confirm the agency's contribution is demonstrable and that original scope gaps have been addressed.
If performance is strong but scope has shifted, use the renewal to restructure the contract rather than just roll it over. At AmpliSell, we offer global marketplace expansion as part of our full-service Amazon management offering. We've seen brands unlock meaningful incremental revenue on Amazon UK, DE, and CA with the right groundwork in place.
Pure-play Amazon agencies are increasingly a constraint for brands that sell or want to sell on TikTok Shop. The two channels interact: TikTok drives social discovery and demand, while Amazon captures that demand at the moment of purchase intent. An agency that manages only one side of that equation is leaving a strategic gap.
Most Amazon agencies don't operate on TikTok Shop. It requires a different skill set: creator affiliate management, short-form video strategy, and fluency with TikTok's discovery algorithm. Brands wanting both channels under one roof must vet agencies specifically for this capability.
AmpliSell is one of the few Amazon-first agencies that also services TikTok Shop. The cross-channel flywheel: TikTok content builds demand and social proof; Amazon listings capture and convert that demand. Off-platform traffic signals also accelerate Amazon organic rank.
In our experience, brands that coordinate both channels see faster Amazon organic rank improvements.
First, audit your internal capabilities and revenue stage to confirm you need outside help. Then define your scope, send a structured RFP to three to five vetted agencies, and evaluate proposals against a consistent scorecard. Negotiate contract terms (retainer, commission, or hybrid) and complete a structured onboarding before measuring results in a 90-day sprint.
Full-service management for $250K–$3M brands runs $3,500 to $7,500 per month in 2026, per SupplyKick and Marknology. Enterprise brands at $10M or more can expect $10,000 to $25,000 per month. Ad-only management is typically 10 to 20 percent of ad spend, with a $2,000 monthly floor.
A retainer model means you pay a fixed monthly fee for a defined scope of services regardless of sales performance. Retainers offer budget predictability and tend to work best when you want broad, ongoing account management rather than purely advertising services.
A commission model ties the agency's fee to a percentage of your Amazon revenue, typically 3 to 10 percent of total sales. It aligns incentives because the agency earns more only when you do. At high volumes it gets expensive and may create pressure to chase short-term revenue over long-term account health.
A hybrid pricing model pairs a base retainer of $2,000 to $5,000/month with a performance incentive. Common incentives include incremental revenue share or tiered bonuses. Hybrid models suit established brands wanting cost predictability while giving the agency upside for strong results.
Most Amazon agencies ask for a six-month minimum. Meaningful results require time for listing optimization, campaign learning phases, and organic rank improvements. Twelve-month contracts are common for full-service engagements.
Insist on a written exit clause that lets you terminate without penalty if KPIs aren't met.
Request a relevant case study with verified revenue numbers, a 90-day account-specific roadmap, named team members, and a full fee breakdown. Also ask for clear KPI ownership and reporting cadence. Requesting a complimentary account audit before signing is common and reasonable.
A full-service Amazon agency can manage: listing optimization, advertising (Sponsored Products, Sponsored Brands, DSP), inventory planning, brand protection, creative, and analytics. Scope varies by agency and contract. Clarify every deliverable in writing before you sign.
Don't hire an agency if you're pre-launch without product-market fit, or if fees would wipe out your margin. Also skip it if your team is expert and only needs one specialist tool. Hiring an agency before your supply chain is stable wastes time and budget.
The first 90 days split into three phases. Days one through thirty focus on account audit, brand immersion, and strategy alignment. Days thirty-one through sixty cover execution: listings rewritten, campaigns launched, creative produced.
Days sixty-one through ninety shift into optimization, with the agency refining based on real data and presenting a growth plan.
Watch for vague case studies, refusal to name your account team, and guaranteed ranking or revenue promises. Also flag pressure to sign long contracts with no exit clause, and agencies pushing software over strategy. A credible agency is transparent about what it can and can't control.
An agency offers faster deployment, broader skills, and lower all-in cost at mid-market revenue levels. An in-house team offers more control over time but requires recruiting, training, and retaining several specialists. Most brands at $1M to $10M find an agency more efficient; larger brands sometimes run a hybrid.
The agency evaluation process is itself a signal. An agency that responds quickly, asks sharp questions, and presents a specific proposal shows you the thinking you'll get. An agency that sends a logo-stamped template and demands a call before sharing details also shows you their process.
