Amazon Agency vs. Amazon Aggregator: What’s the Difference and Which Is Better?

An Amazon agency is a partner you hire. An Amazon aggregator is a buyer you sell to.

That's the clearest way to frame the difference. Agencies help you operate and grow your brand while you keep ownership. Aggregators acquire your brand, take over operations, and give you cash now.

Both solve real problems for Amazon sellers. Neither is universally "better." The right choice depends on what you want: growth with retained control, or an exit with immediate liquidity.

This article breaks down how each model works, what you give up or gain with each, and when one path makes more sense than the other. It also covers a third option that gets less attention: using an agency to improve performance and valuation, then selling to an aggregator at a higher multiple later.

We're writing this in 2026, after the aggregator boom-and-bust cycle. The market looks very different than it did in 2021. That context matters.

What Is an Amazon Aggregator?

An Amazon aggregator is a company that buys profitable FBA brands, consolidates them into a portfolio, and operates them at scale.

The basic model: aggregators identify successful third-party sellers, run due diligence on the business, make an offer (usually 2x to 5x annual net profit), and acquire the brand outright. The seller gets paid in cash, stock, or a mix. The aggregator takes over the seller account, listings, inventory, and operations.

The aggregator thesis (in the boom years) was that acquiring many small-to-midsize brands and running them through a single operational stack would create economies of scale. Shared advertising, logistics, supply chain, and merchandising expertise could make each brand more profitable than it was under solo founder management.

Aggregators raised over $16 billion between 2020 and 2022. Thrasio, the category leader, raised more than $3 billion and acquired over 200 brands. Others followed: Perch, Heyday (now Branded), Razor Group, Berlin Brands Group.

Then the model hit a wall.

Thrasio filed for Chapter 11 bankruptcy in February 2024. The company had taken on $495 million in debt and couldn't service it. It emerged from bankruptcy in June 2024 with a restructuring plan focused on profitability, not acquisition volume. Other aggregators shut down, pivoted, or consolidated.

Funding dropped by more than 80% between 2022 and 2023. The "aggregator" label itself fell out of favor. Many surviving firms now describe themselves as operators, brand builders, or holding companies rather than aggregators.

What went wrong? Most analysts point to a few factors:

Over-acquisition. Aggregators bought too many brands too fast without the operational depth to run them well.

Debt loads. Many firms borrowed heavily at low rates to fund acquisitions. When interest rates rose, servicing that debt became harder.

Operational complexity. Running 200+ separate brands turned out to be harder than running a shared services platform. Each brand had its own suppliers, SKUs, seasonality, and customer base.

Lower-than-expected synergies. The economies of scale thesis didn't play out as strongly as projected. Each brand still needed its own product strategy, content, and advertising approach.

The aggregator model is not dead. But it's no longer the frothy, venture-backed roll-up machine it was in 2021. The firms that survived are more selective, more operationally focused, and much less aggressive about acquisition pace.

For sellers evaluating an exit in 2026, that means the buyer market is tighter. Aggregators now want better margins, cleaner financials, and more defensible brands. The days of getting an offer just because your FBA business hit $1M in revenue are over.

What Is an Amazon Agency?

An Amazon agency is a third-party service provider that helps you run, grow, and improve your Amazon business while you keep ownership.

Agencies handle the specialized work that most brand owners don't have in-house: advertising strategy and execution, listing refinement, A+ content, catalog management, account health monitoring, supply chain coordination, and strategic growth planning.

Amazon's Service Provider Network defines these providers as vetted specialists who help sellers launch, manage, and grow their Amazon businesses. The key distinction: the seller still owns the brand, controls the account, and directs the agency's work.

There are different types of agency arrangements:

Flat monthly retainer: The brand pays a fixed monthly fee for a defined scope of work. Retainers typically range from $1,500/month for lighter support to $10,000+/month for full-service partnerships.

Percentage of ad spend: Common for advertising-focused agencies. Typical range is 10% to 20% of monthly ad spend.

Hybrid models: Some agencies combine a base retainer with a small percentage of sales (often 2% to 5%) or other performance terms.

Project-based: Some agencies take on one-time projects like catalog audits, rebranding, or account reinstatement work.

Equity or revenue-share: A small but growing segment of agencies now offer structures where the agency takes a stake in the business or shares revenue long-term instead of charging traditional fees.

What agencies typically handle:

• Amazon Sponsored Products, Sponsored Brands, and Sponsored Display campaigns
• DSP (demand-side platform) advertising
• Listing copywriting, keyword refinement, and A+ content creation
• Product photography, infographics, and video assets
• Account health management and compliance
• Inventory planning and supply chain coordination
• Vendor Central or Seller Central strategic guidance
• Pricing strategy and promotion planning
• Performance reporting and analytics

Not all agencies do all of those things. Some specialize in advertising only. Others offer full-service support. The scope depends on the agency's model and the brand's needs.

How Amazon Agencies Differ from Consultants

This is worth clarifying because the terms get mixed up.

A consultant typically provides strategic advice, runs audits, and delivers recommendations. The brand owner (or their team) does the actual execution.

An agency does the work. They log into your account, build campaigns, write listings, upload assets, adjust bids, and manage day-to-day operations.

Most Amazon brands need execution help more than they need another slide deck of recommendations. That's why the agency model tends to fit better for sellers who want expert support without hiring a full in-house team.

Amazon Agency vs. Aggregator: Key Differences

Here's the side-by-side breakdown.

The table makes the tradeoff clear: agencies help you operate. Aggregators buy you out.

If you want to keep the brand and improve it, hire an agency. If you're ready to exit and take cash now, an aggregator may be the path. If your goal is somewhere in between, the hybrid path (covered below) can be the right answer.

When an Amazon Agency Is the Better Choice

Hire an agency if:

You want to keep ownership and grow long-term. You like running the business. You see upside. You don't want to sell. You just need expert help executing better than you can alone.

You need specialized skills without building in-house. Hiring a full-time Amazon advertising manager, content writer, account manager, and supply chain coordinator would cost $300,000+ per year in salaries alone. An agency gives you access to a full team for a fraction of that.

You want to increase brand value before a future exit. If you're not ready to sell today but plan to in 2-3 years, working with an agency now can make the business more attractive to buyers later. Better margins, cleaner reporting, stronger catalog performance, and more repeatable processes all increase valuation.

You're not ready to sell or don't meet aggregator thresholds. Most aggregators in 2026 want brands doing at least $1M to $2M in annual revenue with 15%+ net margins. If you're below that, selling isn't an option yet. An agency can help you grow into the range where an exit becomes viable.

You're already thinking about what happens after the sale. Some founders realize they don't actually want to walk away from the business entirely. They like the work. They just want someone else to handle the parts they're bad at or don't enjoy. That's an agency relationship, not an acquisition.

You want flexibility. Agency contracts typically run 6 to 12 months with renewal terms. If the relationship doesn't work, you can end it. If you sell to an aggregator and regret it, you can't unbuy the business.

When Selling to an Aggregator Makes Sense

Sell to an aggregator if:

You're ready to exit and want liquidity now. You've built a profitable FBA brand. You're tired of managing it. You want to cash out and move on to the next thing. You don't want to keep running operations for another 3 years. An aggregator gives you that exit.

Your brand has plateaued and you can't invest in the next growth phase. Perhaps you've hit a ceiling on ad efficiency. Perhaps you need to expand into new product lines or channels but don't have the capital or expertise. An aggregator with deeper resources and operational infrastructure may be able to take the brand further than you can.

You have a strong FBA business but want to move on to other ventures. Some founders build successful brands almost by accident. They're not passionate about the category. They want to start something new. Selling lets them take the equity they've built and redirect it.

You're confident in the valuation and deal structure. In 2026, good aggregator deals are harder to find than they were in 2021. Multiples have compressed. Earn-outs are more common. Due diligence is tighter. But if you get an offer that reflects fair value and you're comfortable with the terms, selling can be the right move.

You understand what you're giving up. You're trading future upside for certainty now. If the brand triples in revenue after the sale, you don't get that gain. If it declines, that's the aggregator's problem. Make sure you're at peace with that tradeoff.

Conditions for Getting a Fair Aggregator Deal

If you do decide to explore a sale, here's what to look for:

Revenue and profitability thresholds. Most aggregators in 2026 want brands doing $1M+ in annual revenue with at least 15% net profit margins. Some will go lower if the brand has strong growth trajectory or defensibility.

Clean financials and operations. Aggregators run full due diligence. They want to see accurate P&Ls, clean supplier contracts, verified revenue, documented inventory processes, and no IP issues. Messy books or operational red flags will kill deals or drive down multiples.

Defensible brand positioning. Aggregators prefer brands with strong organic rankings, repeat customers, Brand Registry, trademarks, and low commoditization risk. If your entire business is buying generic products from Alibaba and slapping a logo on them, you'll struggle to get a fair offer.

Reasonable earn-out terms. Many aggregator deals now include earn-outs: a portion of the purchase price is paid over 12-24 months based on post-sale performance. Make sure those targets are realistic and that you're not on the hook for performance after you no longer control the business.

References from other sellers. Ask the aggregator for references from founders they've acquired from. Talk to those sellers. Find out if the deal closed as promised, if earn-outs were paid on time, and if the process was professional.

Can You Use Both? The Hybrid Approach

Yes. And this is often the smartest path for many sellers.

Here's how it works:

Phase 1: Work with an agency to improve performance and valuation. Hire an agency to professionalize advertising, refine listings, improve margins, and document processes. Spend 12-18 months growing revenue, improving contribution margin, and making the business more attractive to buyers.

Phase 2: Sell to an aggregator at a higher multiple. When the business is performing better, you can command a higher valuation. If your net profit increases by 30% and your multiple stays the same, your exit price just went up by 30%. In many cases, stronger brands also get better multiples because they're less risky for buyers.

This approach makes sense if:

• You're open to an exit eventually but not in a rush.
• You know the business has operational gaps that would hurt valuation today.
• You're willing to invest in growth before you sell.
• You want to maximize exit value, not just exit quickly.

Revenue-share and equity-stake models: A small but growing number of agencies now offer performance-based arrangements where the agency takes a percentage of revenue or a small equity stake instead of (or in addition to) a traditional retainer. These models blur the line between agency and investor. If you want a partner who's incentivized for long-term growth but you're not ready to sell, this can be a middle path.

How to Evaluate an Amazon Agency

If you decide to hire an agency, here's what to look for:

Track record and proof points. Ask for case studies, client references, and specific results. Be skeptical of agencies that only show percentage-lift screenshots without context. Look for agencies that manage meaningful revenue ($10M+, $50M+, $100M+) and have long-term client relationships.

Amazon-specific expertise. General digital marketing agencies often add "Amazon" as a service line without deep platform knowledge. You want a team that understands Sponsored Products bidding, A9 ranking factors, account health policies, and FBA logistics, not just generic PPC principles.

Transparency and reporting. Good agencies give you full visibility into campaign performance, spend, attribution, and strategic decisions. Bad agencies treat reporting as a black box or only show top-line vanity metrics.

Pricing structure. Make sure you understand what you're paying for and what's included. Ask about setup fees, creative costs, additional tool or software fees, and contract length. Avoid agencies that lock you into 24-month contracts with no performance clauses.

Cultural fit. You'll be working with this team regularly. Make sure their communication style, response time, and strategic approach align with how you want to run the business.

Red flags to watch for:

How to Evaluate an Amazon Aggregator

If you're evaluating a sale, here's what to ask:

Funding source and runway. Is the aggregator venture-backed? Debt-financed? Self-funded? How much capital do they have left to deploy? Aggregators that are capital-constrained or carrying too much debt may struggle to close deals or pay earn-outs on time.

Portfolio size and performance. How many brands have they acquired? How many are still active? Ask for examples of brands they've grown post-acquisition and brands that didn't work out. Any aggregator that claims 100% success is lying.

Post-acquisition operational model. What happens to your brand after the sale? Do they keep your existing suppliers? Do they move fulfillment in-house? Do they rebrand or reposition? Understanding their playbook helps you assess whether they're a good fit for your specific business.

Deal structure and terms. What multiple are they offering? How much is cash at close versus earn-out? What are the earn-out conditions? Are you required to stay on as a consultant or operator during transition? Get everything in writing and have a lawyer review it.

References from past sellers. This is non-negotiable. Talk to at least 2-3 founders who sold to the aggregator. Ask if the deal closed as promised, if communication was professional, and if they'd do it again.

Frequently Asked Questions

The Right Path Depends on What You Want

There's no universal answer to "agency vs aggregator."

If you want to keep your brand, grow it with expert help, and retain all future upside, hire an agency.

If you're ready to exit, want liquidity now, and are comfortable giving up future gains for certainty today, explore aggregator offers.

If you're somewhere in between, the hybrid path is worth evaluating: work with an agency to improve performance and valuation, then sell at a higher multiple when you're ready.

The 2026 market is different from the 2021 hype cycle. Aggregators are more selective. Agency partnerships are more common. The choice is less about which model is "winning" and more about which path aligns with your goals, timeline, and risk tolerance.

SupplyKick works with brands at every stage. Some partners want long-term growth and retention. Others want to prepare for an exit in 12-24 months. Both paths are legitimate. The best choice is the one that matches what you're actually working toward.
