Best Amazon FBA Agencies in 2026: 18 Full-Service Agencies Compared

An Amazon FBA agency is a team that runs your Amazon seller or vendor account for a fee: listings, advertising, inventory planning, account health and reporting. It is not the same as an FBA prep centre or a 3PL, which handle physical boxes. This guide compares 18 Amazon FBA agencies and full-service account management services, using what each says on its own website as read on 4 November 2026.

Results quoted by the agencies are their own claims and none were audited. If a price is missing from an entry, that means the agency does not publish one. The numbers in the list are positions, not scores.

What Is an Amazon FBA Agency? The Short Answer

• Prices are rarely public. Only SellerPlex (from $2,500 a month plus 5% of sales above a baseline), Olifant Digital (from $2,000 a month) and AMZDUDES (from $500 a month) state a figure on their own sites.
• Most agencies want an established brand. AMZ Advisers aims at seven-figure brands, SellerPlex at $1M to $20M a year and Olifant Digital at brands with good reviews.
• Check who owns the account. SellerPlex says clients keep ownership of Seller Central and ad accounts. Ask every agency the same question.
• Know what an agency will not do. It manages the account, it does not receive, label or ship your stock. That is a FBA prep service job.
• Under about $50K a month in sales, a specialist or software is often enough. Several guides put the point where full service pays off between $75K and $150K a month, but those are vendor opinions.

18 Best Amazon FBA Agencies and Amazon Account Management Services

1. AMZ Advisers

Full-service agency for established Amazon brands. Founders selling on Amazon since 2014. Agency since 2016. Location not stated.

It covers PPC, SEO, listings, copywriting, A+ content, Brand Stores, 1P vendor consulting, account reinstatement, FBA prep and inbound, DSP, Walmart, TikTok Shop and international expansion. Its US Accelerator programme is aimed at brands that have reached seven figures and stalled. It claims Amazon Ads Advanced Partner status, 550+ brands and $1B in Amazon revenue managed (agency claims), and shows a 4.4 Trustpilot score from 31 reviews on its own page. It offers a free 30-minute audit whose findings you keep, and a written results guarantee for qualifying brands: if a written dollar target is missed it keeps working free for up to 90 more days, capped per quarter.

• Best for: Established brands at about $1M or more that want one team across ads, listings, vendor consulting and expansion.
• Pricing: Not published. Free audit
• Contract: No contract length or notice period stated.
• Watch out for: No pricing is public, very small sellers are routed to a separate programme, and many case studies cover only one week to two months.

2. SellerPlex

Full-service FBA account management with a published fee. Fully distributed team. Founded 2018. SellerPlex says it has 80+ specialists covering PPC, account management and compliance, supply chain and inventory, content, DSP, bookkeeping and profit analytics, FBA reimbursement claims and Brand Registry enforcement. Its homepage says full service starts at $2,500 a month plus 5% of sales above a baseline. It states that clients keep ownership of their Seller Central and ad accounts, that access can be revoked at any time and that there are no multi-year lock-ins. It lists Amazon Ads and SPN Verified Partner status and a 5.0 Clutch score from 25 reviews as shown on its site (agency claims).

• Best for: FBA sellers and brand owners from roughly $1M to $20M a year who want a fixed retainer and account ownership spelled out.
• Pricing: From $2,500 a month plus 5% of sales above a baseline
• Contract: Fixed monthly retainer, no multi-year lock-in. Notice period not stated.
• Watch out for: The baseline for the 5% fee is not defined publicly, it needs user access to manage listings, cases and buyer messages, and it does not guarantee negative feedback removal or gated-category approval.

3. Velocity Sellers

Full-service Amazon management, Seller and Vendor Central. Jericho, New York. Amazon agency since 2016. Velocity Sellers covers account management, PPC and DSP, SEO, A+ content, Brand Stores, catalog, logistics and inventory, Vendor Central, account reinstatement, FBA reimbursements and product launches, plus Walmart, Target and Shopify. It lists Amazon SPN and Amazon Ads partner status and claims $4B+ in revenue generated (agency claims). Its site says most sellers see improvement within 60 to 90 days and notes that FBA itself does not cover listings, advertising or brand protection.

• Best for: Brands on Seller Central, Vendor Central or both that also sell on other marketplaces.
• Pricing: Not published. Site says there is no single price
• Contract: Flexible. No term, notice or cancellation stated.
• Watch out for: No price or minimum account size is public, and the wide scope may suit larger multichannel brands more than small sellers.

4. Canopy Management

Amazon and Walmart account management team. Based in Austin, Texas, operating since 2015. Canopy’s account management side takes in inventory management, lost-inventory reimbursement and listing work, with Amazon SEO, photography and video alongside, and Walmart included. The team is put at more than 100 specialists, and its FAQ says full-service management has no minimum requirement. Its figures of 1,000+ brands, $3.21B in revenue managed and 99.1% partner retention are agency claims we could not verify.

• Best for: Consumer brands that want one team on Amazon, Walmart and creative, smaller brands included.
• Pricing: Not published. Free audit and quote
• Contract: Not stated.
• Watch out for: Pricing and contract terms are not public, and the partner tier is worded two ways on its page: Preferred and Advanced.

5. Incrementum Digital

Ads plus seller operations for CPG brands. Location not stated. Founder and CEO Liran Hirschkorn. Incrementum covers Sponsored Ads, DSP, Creator Connections, brand management and a seller operations service that handles listings and variations, inventory and days of cover, stranded inventory, Seller Support cases, account health, reimbursements, coupons and Lightning Deals. It runs DataOwl, its own analytics platform that combines Amazon sales, ads, DSP and Amazon Marketing Cloud data. It claims Amazon Ads Advanced Partner status, 500+ brands and $500M+ in annual Amazon sales managed (agency claims), with a focus on beauty, supplements, pet, baby and grocery.

• Best for: CPG and consumer brands that want ad management and day-to-day seller operations together.
• Pricing: Not published. Free Amazon Ads audit
• Contract: Not stated.
• Watch out for: FBA is not named as a service on its seller operations page, creative is a separate scope and its case studies are undated.

6. SalesDuo

AI and BI tools plus account management. New York, Seattle, Dubai and Bengaluru offices, plus Newark in Delaware. For FBA sellers the relevant parts are FBA management, listing and A+ content work and, on the Vendor Central side, chargebacks and shortage claims. The agency says an AI assistant called Ethan watches listings and that one BI dashboard joins sales, ads, inventory and profit. It lists Amazon Ads Verified Partner status and claims 350+ brands and $3B+ in client revenue managed (agency claims). It also states who it is a poor fit for, including brands that expect guaranteed results or are not ready on Buy Box and inventory.

• Best for: Small to large brands with active Amazon sales on Seller or Vendor Central and enough catalog complexity to need a team.
• Pricing: Custom, based on ad spend, SKUs, marketplaces and scope
• Contract: No term stated on its site.
• Watch out for: No public price, and DSP, AMC and listing or operations work are usually scoped separately.

7. Olifant Digital

Full Amazon account management, profit-first. Founded 2018, with offices in Grand Island NY, Santa Monica, London, Berlin and Sofia. Olifant runs ads, listings, catalog and inventory as a single account, and adds pricing and reseller control for brand protection. Its AI tool, Olifant AI, checks accounts every day against a contribution margin target, and an account manager reviews every flag. Reports arrive weekly, with a direct Slack channel. It says it is an Amazon Ads Verified Partner (agency claim).

• Best for: Established brands with product-market fit and good reviews.
• Pricing: Retainer from $2,000 a month, quoted to scope rather than as a percentage of ad spend
• Contract: Month to month. It says management fees are refunded if performance has not improved in 60 days (agency claim).
• Watch out for: Early-stage and low-review brands are not accepted, and the $2,000 retainer is a high floor for small sellers.

8. Emplicit

Marketplace agency covering the whole account. San Diego, New York, Chicago and Seattle offices. Emplicit’s scope runs from inventory management, account health and compliance to store setup, brand protection and logistics, with listing and PPC work and some off-Amazon marketing and TikTok Shop on top. Its homepage claims Amazon Ads Verified Partner and SPN membership, $100M+ in managed ad spend and 450+ brands, and the figures differ between parts of the page (agency claims). Under its reseller model the agency takes over payouts, which is worth a close read.

• Best for: Consumer brands that want account management bundled with other marketplace work.
• Pricing: Not published, proposal on request
• Contract: No term stated on its site.
• Watch out for: Its homepage figures are inconsistent, and the reseller model is a control trade-off.

9. My Amazon Guy

Large full-service agency, quote-based. Atlanta, Georgia, with a team in more than 10 countries. The agency lists 400+ employees. On the account side it names account health and suspension reinstatement, catalog and Brand Registry work, FBA and inventory, reimbursements and Vendor Central, with listing SEO, A+ content, brand stores, PPC and DSP as well. It claims Amazon Ads and SPN partner status (agency claims). A free ASIN review or PPC audit comes before a quote. Its own guide to agencies puts itself first, so read that guide as marketing.

• Best for: Sellers around $1M a year or above who want one large team across ads, listings and account health.
• Pricing: Quote only, no price list
• Contract: Not stated for ongoing management.
• Watch out for: Pricing is opaque, and a large full-service shop may be too much for sellers that need only a few services.

10. Seller Interactive

Toronto account management agency. Started in Toronto in 2010. Its account management package includes suspension appeals, reimbursement recovery and brand protection, together with PPC, SEO, listing optimization and DSP, and it also covers Walmart and TikTok Shop. A free Amazon growth audit leads to a tailored proposal. Its claims of 1,300+ brands, $50M+ in managed ad spend and $500M+ in managed revenue are agency claims.

• Best for: Brands that want one team for account health, ads and listings and accept a proposal-based price.
• Pricing: Not published, free audit followed by a proposal
• Contract: No term stated on its site.
• Watch out for: Its headline results mostly cover one-month windows, and a 1,300-brand count sits oddly next to an 18-person team page.

11. Amazing Marketing Co

Supplement, CPG, pet and beauty specialist. Austin, Texas per its homepage, though directories disagree. Founded 2018. Amazing Marketing Co covers growth strategy, AI-assisted PPC, listing optimization in standard and premium tiers, creative, product launches, Seller Central management, account health, FBA inventory management, TikTok Shop and Walmart. It keeps a smaller roster than large agencies and claims $50M+ in managed sales (agency claim). Its homepage says pricing is performance based and depends on account size and scope, and that plans can be taken monthly or yearly.

• Best for: Health, wellness, supplement, CPG, pet and beauty brands from about $10,000 a month upward.
• Pricing: Not published. Quote
• Contract: Monthly or yearly plans. Cancellation terms not confirmed.
• Watch out for: No price or partner status is public, and the niche focus makes it a weaker fit for other categories.

12. Prolific Zone

FBA account management for health and wellness brands. Not stated on its own site. Directories place it in Alberta, Canada. Prolific Zone has 24 team members on its About page and covers full FBA account management, PPC, listing and content optimization, A+ content, launches, Walmart and Shopify management. It claims Official Amazon Advertising Partner status, 30+ active brands and $75M+ in annual revenue managed (agency claims). Its ads page recommends at least $1,500 a month in ad spend, which is budget advice, not a fee. It says the seller keeps account ownership and onboarding takes 7 to 14 days.

• Best for: Health, wellness, supplement, beauty and apparel brands that want a small team.
• Pricing: Agency fees not published
• Contract: Flexible contracts claimed. No term stated.
• Watch out for: Its homepage counters show placeholder zeros, other stats conflict and its case studies are partly anonymised.

13. eStore Factory

Amazon consulting and 360-degree account management. Offices in Sherman Oaks (California), Chesterfield (UK) and Niddrie (Australia). eStore Factory covers account management, PPC, listing optimization, A+ content, Brand Registry services, FBA reimbursement recovery, listing translation and photography, using tools such as SellerQI, BidBison and Refunzo. It says it has 12+ years of experience, claims 5,000+ brands and $250M+ in sales generated (agency claims) and describes month-to-month agreements with no lock-in.

• Best for: New and established sellers in the US, UK and Australia that also want help beyond Amazon.
• Pricing: Not published
• Contract: Month to month, no lock-in (agency claim).
• Watch out for: Its team size and offices differ across pages, it also sells Shopify and general marketing, and it names no Amazon partner tier.

14. Amazon Growth Lab

Boutique agency with limited intake. Based in Culver City, California. A small team of in-house experts handles inventory, account management, review management and brand protection, plus PPC, DSP, creative, A+ content, storefronts and listing optimization. It says it has 12+ years of experience and takes five new clients a month (agency claims). Several headline results are testimonials, or give no time frame.

• Best for: Brands that want a small, selective team and can wait for an opening.
• Pricing: Not published, its blog quotes market ranges rather than its own fees
• Contract: Says it has no long-term contracts (agency claim).
• Watch out for: It claims no Amazon Ads partner badge, and the five-client cap may mean a waitlist.

15. AMZDUDES

Low-entry retainer with account management. Austin, Texas, plus an office in Karachi, operating since 2020. AMZDUDES manages Seller Central and Vendor Central accounts and adds Brand Registry work and FBA consulting to its listing, A+ content, SEO and PPC services. A flat PPC retainer starts at $500 a month, invoiced every two weeks. It says no exit fees apply, calls itself a certified Amazon Advertising Partner and claims 50+ brand partners (agency claims).

• Best for: Private-label and DTC sellers after a low entry price and a short contract.
• Pricing: Retainers start at $500 a month and scale with ad spend and catalog size
• Contract: Month to month, no exit fees (agency claim).
• Watch out for: Its pricing differs between pages, team size is not public and the broad service list may dilute focus.

16. beBOLD Digital

Beauty-first agency that also recovers vendor chargebacks. Based in Costa Mesa, California. The FBA-specific service here is recovery: beBOLD runs vendor chargeback and FBA reimbursement claims for a share of what it recovers. It also manages accounts, Sponsored Ads, DSP, listing SEO, A+ content and brand stores, has a client analytics platform and lists Amazon Ads Verified Partner status. It works on Amazon and Walmart, mainly for beauty, baby and pet brands.

• Best for: Beauty, baby and pet brands, plus vendors needing chargeback recovery.
• Pricing: No fees published on its site
• Contract: No term stated on its site.
• Watch out for: Its beauty-first focus suits other categories less well, and neither price nor contract terms are public.

17. Data4Amazon

High-volume account management and operations. Headquarters not stated on its main site. Founded 1999 per its own blog. Data4Amazon covers Seller Central and Vendor Central account management, covering inventory, orders, pricing, listing upkeep, support cases, chargeback prevention, ASNs and deductions, plus account setup, Brand Registry, account health monitoring and PPC. It says billing can be hourly, monthly or fixed price, offers a free account audit and claims 500+ Amazon experts and 3,500+ stores managed (agency claims we could not verify).

• Best for: Sellers and vendors that want operational support at scale and flexible billing.
• Pricing: Not published. Hourly, monthly or fixed price
• Contract: Not stated.
• Watch out for: Its headcount and location data conflict across sources, many figures are unnamed estimates, and account management is one of many lines, including virtual assistants.

18. BellaVix

Amazon and Walmart management for DTC brands and vendors. Location not stated, founded by Will and Ivonne Haire. BellaVix manages both Seller Central and Vendor Central and adds Walmart marketing, creative and organic work to its PPC, DSP and listing services. It describes itself as a certified Amazon Advertising provider and SPN member, shows a Clutch badge and names Procter & Gamble, Pyrex and Instant Pot among its client logos.

• Best for: DTC brands and wholesale vendors wanting Amazon and Walmart under one team.
• Pricing: Not published, ‘transparent pricing’ is claimed without figures
• Contract: No term stated on its site.
• Watch out for: No pricing, headcount or contract terms are public, and its results are testimonials with no baselines.

How We Compared These Amazon FBA Agencies

The starting point was the agencies named across published lists of Amazon account management and FBA agencies. For each, we read its own site, covering services, pricing, about page, case studies and recent posts. An agency stayed in only if it looked active and sold account management as a real service rather than just ads. We left out an ads-led multichannel agency, a generalist outsourcing shop and a PPC-only specialist, and one agency whose own pages contradicted themselves on team size and results.

Many published lists are written by agencies or vendors that put themselves first, and this one is no exception as a ranking, so use it to build a shortlist. Badges and results are the agencies’ own claims, so check Amazon’s partner directory and ask for references.

What Does an Amazon FBA Agency Do? What Amazon FBA Management Services Include

Amazon FBA Agency vs Prep Center, 3PL, Software and In-House

The term is used loosely. In practice an FBA agency is an account management agency for sellers who fulfil through Fulfilment by Amazon. It owns the digital side of the account. Compare it with the other help you can buy:

Agency, prep or 3PL, software, consultant and in-house compared

What Amazon FBA Management Services Typically Cover

Typical agency scope is listing optimization and A+ content, advertising, inventory and restock planning, account health and compliance, reimbursements and reporting. Brand protection and expansion to other marketplaces are often extra. Read our guides to what Amazon FBA is and FBA versus FBM if you are still deciding how to fulfil, and Amazon inventory management for the planning work an agency should support.

Who Does What: Agency, Shared and Brand

A typical split of responsibilities

FBA Fees an Agency Does Not Control

Amazon sets its own fees, and no agency can lower them. On its Fulfillment by Amazon page, Amazon says fees depend on price, weight and size, that storage is billed monthly by the space you use, and that extra charges can apply to aged inventory, returns processing and removals. An agency can plan restocks and flag slow stock, but the fees stay yours.

How Much Does an Amazon FBA Agency Cost in 2026?

Common Pricing Models

Agencies bill in a few ways, and the model changes who benefits when your sales grow. Ad spend is paid to Amazon and sits outside the agency fee.

Amazon agency fee models

Fees Amazon FBA Agencies Publish

Fees agencies publish on their own sites (read 4 November 2026)

Pricing by Account Revenue

Other guides quote $2,000 to $7,500 a month for small to mid accounts and $8,000 to $25,000 or more for large ones, plus 8% to 20% of revenue or ad spend in percentage models. Those figures come from agencies and vendors with something to sell, so use them only to sense-check a quote. Treat any onboarding fee of several thousand dollars with care, and ask three agencies for a written quote on the same scope. For the fee side of FBA itself, see Amazon FBA fees explained.

When Should You Hire an Amazon FBA Agency, and When You Do Not Need One

The right moment depends on monthly sales and on how much of the account you can still run yourself. The thresholds below come from published guides by agencies, so they are opinions, not rules.

Monthly Amazon sales and the usual fit

You probably do not need an agency yet when sales are small, the catalog has only a few products, or you have the time to learn the account and run it weekly. In that case software, a short course or a freelancer for one job costs less and teaches you more.

If your listings convert poorly, fix that first with our Amazon listing optimization services guide, because no agency can make traffic convert on a weak page.

Seller Central vs Vendor Central: What Full Account Management Covers on Each

Third-party sellers run on Seller Central. Vendors who sell wholesale to Amazon use Vendor Central, which has different reports, chargebacks and purchase orders. Not every agency covers both, so ask. From their own sites:

Vendor Central coverage claimed by agencies in this list

How to Choose the Right Amazon FBA Agency

• Scope in writing. List what is in the fee: listings, A+ content, ads, inventory planning, account health, reimbursements and reports.
• Account ownership and access. You should own the Seller Central account and give the agency permissions you can revoke.
• Fee model. A percentage of total revenue rewards sales you would have made anyway, so prefer a base fee with a share above a clear baseline.
• Category and size fit. A supplement brand needs an agency that knows compliance, and a $30K-a-month seller needs one that accepts small accounts.
• Seller or Vendor Central. Confirm the team has run accounts like yours.
• Reporting. You should see raw data, not only a summary, and receive the report on a fixed schedule.
• Team and capacity. Ask who works on your account and how many other brands they handle.
• Exit terms. Know the notice period and what you keep if you leave.

What to Expect From an Amazon FBA Agency: First 90 Days and Reporting

The First 90 Days

Agencies describe the start differently, but a typical pattern is an audit and access set-up in the first two weeks, quick wins on listings and ads over the next month or so, and a baseline report with a first review by the end of the third month. Ask for the plan in writing and for the baseline numbers before the first change.

Reporting and KPIs

A useful report shows more than ad cost: total sales, ad sales, ACoS and TACoS, organic rank on your main keywords, inventory health and account health, plus the changes made. ACoS is ad spend divided by ad revenue. TACoS divides ad spend by total sales and is a seller convention rather than an Amazon-defined metric.

Amazon Strategic Account Services vs an Amazon FBA Agency

Amazon also offers a programme called Strategic Account Services to some larger sellers, which gives them a named Amazon contact. We could not confirm its current eligibility or fees on an Amazon page, so ask Amazon directly and compare any offer with an agency quote on the same scope. An agency executes, while an Amazon contact advises on Amazon’s own tools. If you want to find a vetted outside provider, Amazon runs the Service Provider Network, and it says it does not endorse the providers and that the contract is between you and the provider.

Questions to Ask an Amazon FBA Agency Before You Sign

• Who owns the Seller Central and advertising accounts, and what access do you need?
• What is in the base fee and what is billed separately?
• If you charge a share of sales, what is the baseline and how is it counted?
• Who will manage my account day to day, and how many brands do they handle?
• How do you handle restock planning and stranded or aged inventory?
• How are inventory, reimbursement and chargeback claims reported to me?
• What is the contract length, the notice period and any setup fee?
• Can I speak to a client in my category who has been with you over a year?

Red Flags When Hiring an Amazon FBA Agency

• Guaranteed rankings or sales. Amazon’s algorithm and your competitors are outside anyone’s control.
• Demands for your password. Agencies should work through user permissions, not your login.
• Case studies with no baseline or time frame. ‘Up 300%’ means little without a start and an end date.
• A large onboarding fee with vague deliverables. Ask for a written list of what the fee buys.
• A long lock-in with no exit clause. A few months to onboard is normal, a year of fees is not.
• No reports on organic sales or profit. Ad metrics alone hide the real picture.
• A ranking that puts the publisher first. Many top lists are written by the agencies they recommend.

Full-Service vs Specialist: Do FBA Agencies Handle Advertising, DSP and Marketing Too?

Most full-service agencies run Sponsored Ads, and many offer DSP. If advertising is your main need, read our comparison of Amazon PPC agencies and management services and the guide to the best Amazon DSP agencies. For broader marketing help, see the best Amazon marketing services.
