Quick Answer: What Is the Best Amazon Agency in the USA in 2026?

There is no single best Amazon agency in the USA. The best fit depends on your annual revenue, ad spend and whether you also sell on TikTok Shop or Walmart. In 2026, most U.S. Amazon agencies charge a flat retainer ($1,500 to $25,000+ per month), 10 to 20% of ad spend, 3 to 10% of revenue, or a hybrid of these. TikTok Shop agencies typically charge $5,000 to $15,000+ per month plus an ad-management fee and affiliate commission.

Fast Picks

• Best for Amazon + TikTok Shop + Walmart under one team: CoTask
• Best for Amazon + TikTok Shop cross-channel: AmpliSell
• Best for full-service Amazon management: SupplyKick
• Best flat-fee option for established brands: Olifant Digital
• Best for PPC-only management: AMZ Pathfinder
• Best for enterprise retail media: Flywheel

Key Takeaways

• Expect to pay roughly $1,500 to $25,000+ per month for Amazon management, depending on scope and brand size.
• TikTok Shop management commonly starts around $5,000 per month, plus ad-management fees and affiliate commission.
• The fee model matters as much as the price: percentage-of-ad-spend models can reward higher spend, not higher profit.
• Reputable agencies rarely guarantee revenue. Look for short contracts, free audits and account ownership instead.
• If you sell on Amazon, TikTok Shop and Walmart, choose one team that reports across all three.

How We Evaluated These Agencies (Methodology)

We built this list for brands with a commercial intent: you are ready to hire, and you want to compare options before booking calls. Each agency was reviewed on six criteria:

1. Marketplace scope: Amazon, TikTok Shop, Walmart and other channels.
2. Pricing model and transparency: published rates, or a clear fee structure.
3. Contract flexibility and guarantees: term length, cancellation, performance commitments.
4. Verifiable credentials: Amazon partner status and public track record.
5. Best-fit brand size: where the agency realistically adds value.
6. Reporting focus: profit metrics (TACoS, GMV) versus vanity metrics.

Disclosure: This guide is published by CoTask, which appears on the list. We have kept claims about every agency to what is publicly stated by that agency or by independent 2026 guides, and we link to sources at the end. Pricing for most agencies is custom, so treat ranges as benchmarks and confirm on a discovery call. Agency details change often, so verify current services and rates before signing.

Amazon & TikTok Shop Agencies in the USA: Comparison Table

The 10 Best Amazon & TikTok Shop Agencies in the USA (2026)

1. CoTask: Best for Multi-Channel Growth with Flexible Contracts

CoTask is a global eCommerce growth agency serving brands in the USA, UK, Canada and Australia. The company states that it is an Amazon SPN Partner and Amazon Ads Verified Partner, and that it operates with an in-house team rather than freelancers. It reports 200+ brands served and 7+ years in business.

• Services: Amazon management, Amazon PPC management, Walmart Marketplace management, TikTok marketing and TikTok Shop (shop setup, creator and affiliate programs, LIVE selling, GMV Max and Spark Ads), plus Shopify development.
• Contracts: CoTask says it uses flexible 3-month and 6-month agreements with no long-term lock-in and offers a free account audit before you commit.
• Pricing: Custom quote. Request a free audit or book a consultation.
• Self-reported results: An average 40% ACoS reduction within 60 days across PPC accounts. These figures are published by CoTask itself, so ask for account-level examples relevant to your category.
• Best for: Brands that sell on several marketplaces and want one team across Amazon, TikTok Shop and Walmart.
• Consider if: You need a large enterprise retail-media software suite; larger holding-company agencies may fit better.

2. AmpliSell: Best for Amazon + TikTok Shop Cross-Channel

AmpliSell describes itself as an Amazon-first agency that also manages TikTok Shop, so TikTok campaigns can create demand that is captured on Amazon. It uses custom pricing. This is a good shortlist candidate if you want a single agency to plan both channels together. Note that this description comes from the agency's own buyer's guide.

3. SupplyKick: Best for Full-Service Amazon Management

SupplyKick positions itself as a full-service Amazon agency that began as an Amazon retailer. Its published guide places typical full-service engagements at roughly $5,000 to $15,000 per month, and says it prices by scope rather than as a percentage of ad spend. It is a strong option for brands that want listing, advertising and operations support in one place.

4. Olifant Digital: Best Flat-Fee Option for Established Brands

Olifant Digital is listed in a 2026 roundup as starting at $2,000 per month on a flat retainer with no percentage-of-spend fees, and is aimed at brands with $1M+ in annual Amazon revenue that care about margin. Flat fees remove the incentive to inflate ad spend, which is a real advantage if you are cost-sensitive.

5. AMZ Pathfinder: Best for Hands-On Amazon PPC

AMZ Pathfinder is known for deep Amazon PPC specialization across multiple marketplaces. Choose a PPC-focused partner if your listings and inventory are healthy and you mainly need better advertising performance.

6. Flywheel: Best for Enterprise Retail Media

Flywheel, part of Omnicom since 2024, pairs managed retail media services with software that spans Amazon, Walmart, eBay and TikTok Shop. It publishes no rate card. It tends to suit larger brands with big media budgets and complex reporting needs.

7. Canopy Management: Best for Fixing Account Problems Before Scaling

Canopy Management is an Austin-based full-service agency that focuses on fixing issues that hold growth back before increasing ad spend. Pricing is quoted per scope.

8. Cartograph: Best for CPG Brands

Cartograph is a full-service Amazon agency specializing in consumer packaged goods. It was acquired by Harvest Group in April 2026, so ask about team continuity and service changes during your evaluation.

9. My Amazon Guy: Best for Amazon-Only Focus

My Amazon Guy focuses on Amazon and does not publicly offer TikTok Shop management, according to a 2026 comparison. If you only sell on Amazon and want specialist depth, it is worth a call. If you need TikTok Shop too, choose from agencies 1 or 2.

10. MarketerHire: Best Fractional Alternative

Not every brand needs a full agency. MarketerHire publishes a 2026 guide on when a fractional TikTok Shop marketer is smarter than a retainer agency. This route can suit brands with under roughly $2M in annual TikTok Shop GMV that want one senior expert rather than a team.

How Much Does an Amazon Agency Cost in the USA? (2026 Pricing)

Amazon agency pricing in 2026 generally falls into four models. Ranges below come from published 2026 agency guides and will vary by scope.

Amazon PPC Agency Cost

PPC-only management commonly runs about $1,000 to $5,000 per month as a retainer, or 10 to 20% of monthly ad spend. Full-service management (PPC, listings, catalog and operations) is more often $5,000 to $15,000 per month, and strategic partnerships for $5M+ brands can reach $15,000 to $50,000+ per month.

TikTok Shop Agency Cost in the USA

Published 2026 benchmarks range from about $5,000 to $15,000 per month for core TikTok Shop management, with premium retainers reaching $40,000 per month. Many agencies add a 5 to 15% ad-management fee and a 5 to 20% commission on affiliate-driven revenue. Ad spend is paid separately; mid-market brands often spend $30,000 to $150,000 per month on TikTok Shop ads. TikTok Shop is forecast to reach about $23.4 billion in U.S. sales in 2026, according to EMARKETER, which explains the rising demand for specialists.

Walmart Marketing Agency Cost

Walmart pricing is rarely published. Expect quotes structured like Amazon agency fees (retainer, percentage of ad spend or hybrid). If you already work with an Amazon agency, ask for a combined Amazon and Walmart quote, as multi-channel teams often bundle the two. See CoTask's Walmart Marketplace management service as an example scope.

Worked Example: What Will You Actually Pay?

The same brand can pay very different fees depending on the model. Here is the math for a brand spending $20,000 per month on Amazon ads with $100,000 in monthly Amazon revenue:

For TikTok Shop, a brand spending $50,000 per month on ads with a $6,000 retainer and a 10% ad-management fee pays $11,000 per month in agency fees. That equals 22% of ad spend, before any affiliate commission. Always calculate your effective fee rate before signing.

What Do Amazon Management Services Include?

Amazon management services typically cover:

• Account setup and optimization: Amazon seller account management, brand registry support and compliance.
• Listing optimization: keyword research, titles, bullets and A+ content.
• Advertising: Sponsored Products, Brands and Display, and sometimes DSP.
• Inventory and operations: forecasting, FBA/FBM guidance, reimbursements.
• Reporting: ACoS, TACoS, conversion rate, share of voice and profit.

Key metrics: ACoS is ad spend divided by ad-attributed revenue. TACoS is ad spend divided by total Amazon revenue, including organic sales. A good agency reports both to catch ad spend that cannibalizes organic performance.

Guarantees and Contract Terms: What to Expect

Be skeptical of any agency guaranteeing a specific revenue number. Amazon's algorithm, your product, pricing and competitors all affect results, and independent guides warn that weak agencies blame external factors without a plan. Realistic protections include:

• Short, flexible terms: month-to-month or 3- to 6-month agreements instead of 12-month lock-ins.
• Free audits: a no-cost account review before you sign.
• Transparent reporting: access to your own Seller Central and ad accounts at all times.
• Clear exit terms: you keep ownership of your account, listings and creative.
• No hidden minimums: avoid clauses that force a minimum ad spend.

Red Flags When Hiring an Amazon or TikTok Shop Agency

• Guaranteed rankings or revenue. No agency controls Amazon's algorithm or your product-market fit.
• Refusing account access. You should always own and see your Seller Central, Ads and TikTok Shop accounts.
• 12-month lock-ins or minimum ad spend clauses. These shift risk onto you.
• ACoS-only reporting. Without TACoS, profit or GMV, you cannot tell whether ads are cannibalizing organic sales.
• No named team. Ask who will work on your account and whether they are in-house.
• No category-relevant results. Ask for examples from brands of your size and category.

What to Expect in the First 90 Days

A typical onboarding sequence, which you should confirm with any agency you shortlist:

1. Days 1 to 14: Audit and access. Account health, listing quality, ad structure, inventory and compliance review. CoTask states its process starts with a free audit and a custom strategy, then launches optimizations within 14 days.
2. Days 15 to 45: Optimization. Listing rewrites, campaign restructuring, negative keywords, creative or affiliate setup for TikTok Shop.
3. Days 45 to 90: Scale and report. Budget moves toward profitable products, with reporting on TACoS, profit or GMV. CoTask states that measurable results typically appear within 30 to 45 days; treat any such timeline as a target, not a promise.

If you are not seeing a clear plan and a reporting cadence by day 30, escalate.

8 Questions to Ask Before Hiring an Amazon Agency

1. Who will actually manage my account, and is that team in-house?
2. Which pricing model do you use, and what is excluded from the fee?
3. Do I own the Seller Central, Ads and creative assets?
4. What KPIs will you report: ACoS, TACoS, profit or GMV?
5. Can you share results from brands in my category and size?
6. What is the minimum contract term and how do I cancel?
7. Are you an Amazon SPN or Ads partner, and can that be verified?
8. How will you coordinate Amazon, TikTok Shop and Walmart if I use all three?

Final Verdict

Choose an agency based on fit, not rankings. A multi-channel seller needs a different partner than an Amazon-only brand. Compare pricing models, insist on short contract terms and ask for category-relevant results. If you want a free review of your Amazon, TikTok Shop or Walmart account, get a free audit from CoTask or book a 15-minute consultation.
