An Amazon agency manages some or all of a brand's Amazon channel operations. That includes listing optimization, PPC advertising, inventory planning, brand protection, and performance reporting, in exchange for a retainer or revenue-share fee. It acts as an extension of the brand's team, not a replacement for brand ownership or decision-making.
If you've wondered exactly where an agency's work starts and yours ends, this walkthrough covers every major service area. For each, we'll cover what the agency handles, what the brand owns, and the time cost of doing it in-house.
Seller Central
Amazon's web portal for third-party sellers. Agencies operate inside Seller Central on behalf of a brand, but the account belongs to the brand, not the agency.
ASIN
Amazon Standard Identification Number. Each product variation on Amazon has its own ASIN, and most agency work is organized at the ASIN level.
PPC (Pay-Per-Click)
Amazon's self-service advertising system covering Sponsored Products, Sponsored Brands, and Sponsored Display. The advertiser pays only when a shopper clicks the ad.
DSP (Demand-Side Platform)
Amazon's programmatic advertising platform. DSP serves display and video ads on Amazon properties and third-party sites, targeting audiences rather than keywords.
A+ Content
A rich visual module that replaces the plain product description on Amazon detail pages. It requires Amazon Brand Registry enrollment to publish.
Brand Registry
Amazon's free program for trademark owners. It unlocks A+ Content, Sponsored Brands, Brand Analytics, and brand protection enforcement tools.
TACoS (Total Advertising Cost of Sale)
Ad spend divided by total revenue, including organic sales. TACoS is the agency's primary efficiency metric because it reflects advertising health relative to the whole business.
FBA (Fulfillment by Amazon)
Amazon's logistics service where sellers ship inventory to Amazon warehouses and Amazon handles picking, packing, and shipping to customers.
Amazon's management surface is enormous. A single brand with 50 ASINs can have hundreds of active ad campaigns and dozens of listing variations to keep compliant. Add multiple restock orders and a constant stream of customer messages, and it's a full-time operation.
In our work with brands across categories, we've consistently found that in-house teams underestimate the hours required to manage Amazon well. The platform rewards daily attention, and most internal teams simply don't have it to give.
Full-channel Amazon management, done properly, typically requires 20 to 40 hours per week across advertising, content, inventory, and account health. A dedicated agency team compresses that output by running specialized workflows in parallel, where an in-house generalist would work sequentially.
Below is a practitioner's view of each service area. We'll cover what a full-service agency handles, what the brand retains, and the time cost of doing it alone.
The agency's account management function covers the day-to-day health of your Seller Central account. This includes monitoring account health metrics, responding to Amazon policy notices, and managing user permissions. The agency also coordinates across all other service areas to keep the account in good standing.
The brand still owns the account credentials, the legal relationship with Amazon, and every final decision on pricing and distribution policy. The agency operates as an authorized user under the brand's account.
In-house, account management alone runs five to ten hours per week. That includes policy monitoring, case management with Amazon support, and internal coordination. Agencies distribute this work across a dedicated account manager and supporting analysts.
When we onboarded Elgin USA, the brand had unresolved account health warnings limiting ad eligibility. Our account management team cleared the backlog in two weeks, restoring full advertising access. That work contributed to the brand reaching $300K per month within three months of launch.
Listing optimization means researching the right keywords, writing titles and bullets that convert, and building A+ Content. It also means keeping every ASIN compliant with Amazon's evolving style guidelines. It's equal parts SEO, copywriting, and conversion rate optimization.
The brand owns the product knowledge, brand voice guidelines, and final approval on copy. A good agency learns the brand's positioning and translates it into language Amazon's algorithm and its shoppers both respond to.
For a catalog of 20 to 50 ASINs, a from-scratch listing overhaul typically takes 40 to 80 hours. Ongoing refreshes and compliance updates add roughly five to ten hours per month. Agencies run this through dedicated content teams who specialize in Amazon copy, not general marketing copy.
PPC management is often the highest-value service an agency provides. It covers campaign architecture, keyword research, bid management, and budget allocation. That also includes negative keyword strategy and creative testing across Sponsored Products, Sponsored Brands, and Sponsored Display.
The brand sets the advertising budget ceiling and approved messaging. The agency operates within those parameters and reports weekly on spend efficiency, TACoS, and return on ad spend (ROAS).
Effective PPC on a mid-size catalog requires daily bid reviews, weekly structural optimizations, and monthly strategic recalibrations. In-house, that's 15 to 25 hours per week without automation tooling. AmpliSell combines AI-trained ad software with human specialists, allowing faster iteration across a larger ASIN set than a solo manager can achieve.
Brands moving from self-managed to agency-managed PPC typically see TACoS improvement in the first 60 to 90 days. Wasted spend is cut and high-converting keyword structures are built quickly. Condition 1 saw 152% revenue growth in six months following this transition.
Amazon DSP lets agencies buy programmatic display and video inventory on Amazon's owned sites and across a network of third-party publishers. Unlike PPC, DSP targets audience segments: past purchasers, category browsers, competitor product viewers, and more.
DSP is managed entirely on the agency side because most brands lack direct DSP access. The brand approves creative assets and audience strategy, and the agency handles the platform execution and reporting.
DSP typically requires a meaningful monthly minimum to run efficiently. An agency will advise you honestly on whether your current scale justifies DSP or whether PPC optimization should come first.
Creative covers product photography, lifestyle and infographic images, video content for listings and ads, A+ Content design, and Brand Store builds. Strong creative is what converts traffic that advertising drives to a listing.
The brand owns all finished creative assets. The agency needs brand guidelines, product samples or existing photography, and approval at defined review stages. Turnaround times, revision rounds, and asset ownership should all be spelled out in the agency contract.
Sourcing freelance photography and design for a 20-ASIN catalog adds 20 to 40 hours of project management on top of vendor fees. In-house teams without dedicated design resources often end up with inconsistent visuals, which limits conversion rates on even well-optimized listings.
Inventory management for Amazon includes demand forecasting, restock recommendations, FBA shipment creation, and overstock and storage fee monitoring. The agency also coordinates with the brand's 3PL or warehouse team. Running out of stock kills organic rank and stops ads from serving.
The brand owns the physical inventory, the supplier relationships, and the production lead times. The agency models when to reorder and how much, flagging risks early so the brand has time to act.
Demand planning for a seasonal catalog can absorb five to ten hours per week during peak periods. Agencies use dedicated demand planners who track velocity changes, promotional lifts, and FBA lead times across an entire client portfolio. That cross-portfolio visibility gives them pattern recognition a single-catalog brand simply won't have.
Brand protection covers monitoring for unauthorized sellers on listings, counterfeit products, listing hijacks, and suppressed ASINs. Agencies enrolled through Amazon Brand Registry can file violation reports, monitor the Buy Box, and escalate persistent infringers.
The brand retains control of the Brand Registry account and any trademark filing decisions. The agency handles daily monitoring and enforcement filings. It escalates to the brand only when legal action or supplier negotiation is required.
Without proactive monitoring, brands can lose the Buy Box to unauthorized resellers for days or weeks before anyone notices. In-house monitoring without tooling is reactive, not preventive.
Amazon measures seller response rates and response times, and poor performance affects account health, feedback scores, and advertising eligibility. Agencies handling customer service monitor the brand's message inbox, respond to buyer questions, and manage return and refund requests. They also surface recurring product feedback to the brand team.
The brand owns warranty and recall decisions, complex dispute resolution, and the product knowledge the agency needs to answer questions accurately. Most agencies develop a brand-specific FAQ and escalation protocol during onboarding.
Customer service typically requires two to three hours per day for an active seller. Agencies absorb this into their support workflows, freeing brand teams to focus on product and strategy.
Reporting connects all the service areas into a coherent picture of channel performance. A full-service agency delivers regular reports covering revenue, units sold, ad spend, TACoS, and ROAS. Reports also track organic rank for key terms, Buy Box ownership, and inventory health.
The brand owns its own data and should always have direct access to Seller Central and Brand Analytics. An agency that restricts your data access is a red flag. Read more in 9 Red Flags to Watch For When Hiring an Amazon Agency.
Good reporting takes two to four hours per week to build and interpret correctly. Agencies present insights, not just numbers. They tie each report to decisions: what's working, what needs to change, and where the next growth lever is.
Ask any agency you're evaluating to show you a sample report before you sign. Look for clean data visualization, a clear narrative, and action items tied to each metric. A report that only shows green numbers without context isn't useful for making decisions.
| Service | What the agency does | What the brand still owns | In-house time if DIY |
|---|---|---|---|
| Account and channel management | Monitors account health, manages cases, coordinates operations | Account credentials, legal relationship with Amazon, pricing decisions | 5-10 hrs/week |
| Listing optimization | Keyword research, title/bullet copywriting, A+ Content, compliance | Product knowledge, brand voice, final copy approval | 40-80 hrs upfront; 5-10 hrs/month ongoing |
| Sponsored advertising (PPC) | Campaign architecture, bid management, keyword strategy, budget pacing | Budget ceiling, approved messaging, brand safety decisions | 15-25 hrs/week |
| DSP advertising | Programmatic audience targeting, creative deployment, reporting | Creative asset approval, audience strategy sign-off, budget | Requires platform access most brands don't have |
| Creative production | Photography, infographics, video, A+ design, Brand Store | Brand guidelines, product samples, final asset approval | 20-40 hrs PM time per catalog refresh |
| Inventory management | Demand forecasting, restock recommendations, FBA shipment creation | Physical inventory, supplier relationships, production lead times | 5-10 hrs/week (peak periods higher) |
| Brand protection | Unauthorized seller monitoring, violation filings, Buy Box tracking | Brand Registry account control, trademark decisions, legal action | 2-5 hrs/week without automation tooling |
| Customer service | Message responses, returns, feedback monitoring, escalation protocol | Warranty decisions, recalls, complex disputes, product knowledge | 2-3 hrs/day |
| Reporting and analytics | Dashboard builds, weekly/monthly reports, insight narrative, action items | Data access (Seller Central, Brand Analytics), strategic direction | 2-4 hrs/week |
In practice, a full-service agency assigns a dedicated account manager as the brand's primary contact. Behind that account manager is a team of specialists: advertising managers, content writers, graphic designers, demand planners, and brand protection analysts.
At AmpliSell, each client gets a dedicated account manager backed by brand managers, analysts, demand planners, ad specialists, and a creative team. No single person handles all nine service areas at once.
The cadence typically includes a weekly sync call, a standing report on a set day, and an async channel for urgent issues. The brand's time commitment drops to roughly two to four hours per week, compared to 20 to 40 hours in-house.
A good agency is clear about its scope. It does not own your account, your inventory, or your intellectual property. It does not make unilateral pricing decisions or approve its own ad spend without agreed budgets.
Agencies also don't manufacture outcomes. They optimize the inputs: listings, ads, creative, and operations. Results depend on product-market fit, competitive landscape, and pricing, all of which the brand controls.
If an agency promises a specific revenue number before it has audited your account, treat that as a warning sign. You'll find a full list of warning signs in 9 Red Flags to Watch For When Hiring an Amazon Agency.
The core trade-off isn't cost; it's specialization and bandwidth. An in-house manager goes deep on one catalog but rarely builds the cross-category pattern recognition an agency develops across dozens of clients.
We covered this comparison in detail in Amazon Agency vs In-House Team: Which One Wins for a Growing Brand?. The short version: in-house makes sense when Amazon is your primary business and you need full strategic control. An agency makes sense when your team's time is better spent elsewhere, or when you need specialized skills fast.
For Maelove, moving to a full-service agency model enabled a $0 to $3.6 million revenue run in 11 months on Amazon. The brand's small internal team could not have executed that while also managing product development and DTC operations.
In our experience, the brands that get the most from an agency partnership are the ones that stay engaged as strategic owners. They show up to syncs, share product intel early, and make decisions quickly. Brands that go fully passive tend to see slower improvement because the agency lacks the context to act confidently on their behalf.
Not every agency covers every service area listed above. Some specialize in advertising only; others offer full-service management. When you evaluate options, map each agency's stated scope against the service areas where your brand needs the most help.
Our guide The Definitive Guide to Hiring an Amazon Agency in 2026 walks through the full evaluation framework. 15 Questions to Ask Before Hiring an Amazon Agency gives you a ready-made interview checklist for discovery calls.
When comparing agencies, ask specifically about team structure, reporting access, contract length, and how they handle account transitions if you part ways. Those four points reveal more than any sales deck.
An Amazon agency manages some or all of a brand's Amazon channel on its behalf. Core responsibilities typically include listing optimization, sponsored advertising, DSP, creative production, inventory planning, brand protection, customer service, and performance reporting. The agency acts as an extension of the brand's team rather than a replacement for it.
An agency does not own the brand's seller or vendor account, its inventory, or its intellectual property. Final decisions on pricing strategy, product launches, and budget ceilings always belong to the brand. A good agency advises clearly and executes fast, but it operates within the brand's guardrails.
Expect to spend two to four hours per week with your agency: weekly syncs, reviewing reports, and approving creative changes. That's far less than the 20 to 40 hours a brand typically spends managing Amazon in-house.
Amazon PPC (Pay-Per-Click) refers to Sponsored Products, Sponsored Brands, and Sponsored Display ads on Amazon. Effective campaigns require daily bid adjustments, keyword harvesting, negative keyword pruning, and budget pacing across dozens or hundreds of ASINs. Most brand teams don't have the bandwidth or tooling to do this profitably at scale.
Amazon DSP (Demand-Side Platform) lets advertisers reach audiences on Amazon-owned properties and third-party websites using display and video ads. Unlike PPC, DSP targets audiences rather than keywords, making it effective for retargeting, new-to-brand acquisition, and cross-category awareness. DSP is typically worthwhile for brands spending above a meaningful monthly threshold; your agency can advise whether DSP fits your current scale.
Listing optimization means rewriting titles, bullets, descriptions, and backend search terms so Amazon's algorithm surfaces the product for the right queries. A well-optimized listing also converts shoppers once they land, reducing wasted ad spend and lifting organic rank.
Agencies enrolled in Amazon Brand Registry can monitor for counterfeit listings, unauthorized sellers, listing hijacks, and suppressed ASINs on a brand's behalf. They file violation reports through Brand Registry tools and, when needed, escalate to Amazon's selling partner support. The brand retains control of the Registry account; the agency manages the day-to-day policing.
Many full-service Amazon agencies monitor and respond to customer messages, handle return requests, and flag product feedback trends to the brand team. Response times on Amazon directly affect seller metrics, so agencies often build this into their scope to protect account health. The brand remains responsible for warranty decisions and product recalls.
A+ Content (formerly Enhanced Brand Content) is the rich visual module that replaces the plain product description on Amazon detail pages. Full-service agencies design and write A+ Content using the brand's photography and guidelines, then publish it through Amazon's Brand Registry tools. Studies consistently show that A+ Content improves conversion rates versus plain text descriptions.
Most full-service Amazon agencies charge a monthly retainer, a percentage of managed revenue, or a hybrid of both. Some also charge a percentage of ad spend for standalone advertising work. Setup fees for onboarding are common in the first month.
Specific pricing varies by agency and scope. See the agency's published service page or request a proposal for accurate figures.
Most brands benefit from an agency once they're generating meaningful Amazon revenue but spending more time managing it than the revenue warrants. If your team loses hours to ad management, listing issues, or account health problems, outside help will likely pay for itself.
Look for a dedicated account manager, transparent reporting with access to your own data, and verifiable case studies in your category. Also ask for a clear statement of what the agency handles versus what stays with you. Be wary of agencies that promise specific sales figures upfront or lock you into long contracts with no performance clauses.
