Scaling an e-commerce brand on TikTok requires a massive shift away from traditional, highly produced advertising. But finding an agency that actually moves the needle is a real headache. Many brands just swap their flatlining sales for generic content packages, overpriced influencer fees, and account managers who look at views instead of conversion metrics. Worse, most video-focused agencies completely ignore back-end operations, leaving you stranded when it comes to matching explosive TikTok demand with actual marketplace inventory across platforms like Amazon.

If you are tired of empty engagement metrics, you need a partner with an owner’s mindset who knows how to tie viral content directly to channel management, supply chain forecasting, and bottom-line profit. We looked at the top 10 agencies making the cut right now based on real sales numbers and straightforward multi-channel strategy.

1. AmpliSell

For ambitious brands losing market share and momentum to aggressive competitors, AmpliSell closes the execution gap by transforming underperforming Amazon and TikTok Shop presence into a high-yield revenue engine. Specializing in full-service channel management, AI-optimized advertising, and high-converting listing design, they systematically capture social demand and turn it into marketplace dominance.

• Over $125 million in added revenue: They have engineered more than $125M in incremental sales and successfully launched over 1,000 products for brands seeking true enterprise scale.
• An owned community of 500+ top-tier creators: While most agencies start every campaign with cold outreach, AmpliSell pulls from a private, vetted community of more than 500 creators with proven TikTok Shop sales histories, hand-matched to each product’s niche. Community creators post roughly 4x more often than one-off hires, and their UGC typically converts 3 to 5x better than brand-produced content, which makes the network a compounding content engine most competitors can’t replicate.
• A flywheel, not a viral lottery: The playbook: identify the hero SKUs that stop the scroll, seed 200+ samples a month into the creator community, let the winning content surface, then amplify it with GMV Max and Spark Ads.
• Built for the halo effect: TikTok Shop demand doesn’t stay on TikTok. Independent research shows TikTok driving roughly 34% in additional Amazon sales for brands selling on both channels, and AmpliSell is one of the few agencies that manages both sides of that equation, so the halo lands in listings that are already optimized to convert it.
• A one-stop shop with an owner’s mentality: Unlike bloated agencies that treat accounts like an afterthought or assign them to overloaded generalists, they run your business with the precision of former sellers, deploying a proprietary roadmap that unifies channel strategy, listing content, disciplined demand planning, and aggressive ad optimization under a single, accountable team.

2. The Social Shepherd

The Social Shepherd is a full-service social agency with offices in London, Bath, New York, and Miami, and TikTok Shop has grown into one of its flagship offerings. They are a strong pick for brands that want organic content, creator affiliates, and paid media handled together instead of split across vendors.

• Full-funnel Shop management: They cover the whole arc, from product roadmap and shop setup through affiliate creator recruitment, trend-led content production, and GMV Max ad campaigns, so nothing falls into the gap between “content team” and “media team.”
• Paid and organic under one roof: Because the same team runs your always-on creative and your performance spend, winning organic posts get amplified into paid placements quickly, while underperforming angles get killed before they burn budget.

3. Ubiquitous

Ubiquitous made its name as a TikTok-first influencer marketing agency and has run campaigns for some of the biggest consumer names on the platform. If creator volume is the engine of your TikTok Shop strategy, these are the specialists.

• Creator matchmaking at scale: They maintain a large vetted creator network and handle sourcing, negotiation, briefing, and rights management, the operational grind that makes most in-house affiliate programs stall out.
• Influencer content treated like a paid channel: Campaigns are managed against real media metrics (cost per acquisition, view-through to purchase) rather than vanity engagement, which keeps creator spend accountable to revenue.

Iced Media is a New York social commerce agency with deep roots in beauty and skincare, counting brands like Kiehl’s, La Roche-Posay, and Elizabeth Arden among its clients. For beauty brands, category fluency matters more than generalist reach, and this is where they shine.

• Beauty category depth: They understand the ingredient-led content styles, creator archetypes, and compliance sensitivities that drive conversion in beauty, a category where TikTok Shop moves serious volume.
• Catalog-to-checkout integration: Beyond content, they handle the unglamorous work of catalog integration, shop strategy, and affiliate creator programs so the storefront actually converts the traffic the content generates.

5. Pattern

Pattern is an enterprise marketplace accelerator that manages brands across dozens of marketplaces worldwide, with TikTok Shop sitting alongside Amazon and Walmart in a single operating model. It is built for large brands that want one partner across every channel.

• True omnichannel visibility: Because they run your Amazon and TikTok Shop presence together, they can see how viral social demand spills over into marketplace search, and position inventory and pricing accordingly.
• Enterprise-grade infrastructure: Global logistics support, data science teams, and marketplace compliance expertise make them a fit for brands where a stockout or a pricing error is a seven-figure problem.

6. Harvest Group

Harvest Group is a full-service retail sales agency that grew up serving major CPG brands, with clients like Magic Spoon, Bush’s Beans, and Bragg, and has built out a certified TikTok Shop practice. They are a natural fit for food, beverage, and household brands coming from traditional retail.

• CPG and retail DNA: They understand velocity-driven retail economics, trade spend, and how a TikTok moment translates (or doesn’t) into shelf and e-commerce performance across the rest of your accounts.
• Certified Shop operations: Their TikTok Shop offering spans ads, affiliate programs, and e-commerce integration, run by the same teams that manage those brands on Amazon and Walmart.

7. inBeat

inBeat is a creative growth agency that pairs micro-influencer networks with paid amplification, and has worked with names like Bumble, Disney, and Nestlé. Their model suits brands that want a high volume of authentic content without betting the budget on a few big creators.

• Micro-creator engine: Instead of chasing celebrity talent, they orchestrate dozens of smaller creators whose content reads as native to the feed, which is exactly what converts on TikTok Shop.
• Performance amplification: The best organic performers get pushed through Spark Ads and paid social, turning proven creative into a scalable acquisition channel rather than a one-off viral spike.

8. House of Marketers

House of Marketers is a London-based TikTok agency founded by former TikTok employees, which gives them a platform-insider perspective that most agencies imitate secondhand. They work with global brands across the US, UK, and Europe.

• Insider platform knowledge: Having worked inside TikTok, the leadership team understands how the algorithm, ad auction, and commerce features actually behave, and builds campaign strategy around it.
• International reach: For brands eyeing TikTok Shop expansion beyond the US, their footprint across UK and European markets makes them one of the stronger cross-border options.

9. Stella Rising

Stella Rising is an award-winning digital media agency specializing in beauty and wellness, with a certified TikTok Shop practice and clients including Laneige, Sulwhasoo, and Real Techniques.

• Media strategy meets social commerce: They bring a full media-agency toolkit (search, paid social, influencer activations) to TikTok Shop, so shop performance is planned as part of your whole media mix rather than in a silo.
• Beauty and wellness pedigree: Their client roster gives them pattern recognition in the categories where TikTok Shop conversion runs hottest.

10. Avenue Z

Avenue Z blends commerce operations with PR and media relations, an unusual combination that works well for brands trying to turn TikTok momentum into mainstream visibility. They are a TikTok Shop Agency Partner with clients like Yogibo and Klora.

• Commerce plus narrative: The same firm that runs your shop setup, product integrations, and affiliate marketing can also pitch the story to press, compounding a viral product moment into earned media.
• End-to-end coverage: Their scope stretches from storefront setup through affiliate programs and even fulfillment coordination, useful for lean teams that would rather manage one relationship than five.
