10 Ways to Source Amazon FBA Wholesale Suppliers

Finding the right Amazon FBA wholesale suppliers is one of the biggest challenges wholesale sellers face. Some brands may be restricted or not profitable to sell on Amazon, while some suppliers may not be reliable, or simply don’t respond. This makes it hard to scale consistently or maintain healthy profit margins. 

That’s why having reliable sourcing strategies is critical  –  you need suppliers you can trust, with products that match your goals. We have a few product research tactics for that.

In this post, you’ll discover 10 proven ways to find high-quality Amazon FBA wholesale suppliers, including how to leverage tools like Brand Analyzer, sourcing directories, curated supplier lists, and more  –  all tailored to help you source smarter and grow your Amazon business faster.

Strategy 1. Research and Open a Brand

What it is

This strategy involves finding profitable and resale-friendly brands to work with directly by using Seller Assistant's Brand Analyzer. Instead of randomly selecting suppliers, you evaluate each brand’s revenue potential, product range, competition, and resale eligibility to ensure a strategic fit.

How it works

Start by entering a brand name into the Brand Analyzer. The tool will return data points such as the brand’s total number of ASINs, average monthly revenue, number of competing sellers, Amazon in-stock rate, product ratings, and Buy Box prices. Once you’ve identified a suitable brand, reach out to them directly, express your interest in reselling their products, and ask about their pricing structure and Minimum Order Quantities (MOQs).

What Brand Analyzer does

Brand Analyzer delivers a complete snapshot of key indicators  –  including revenue, competition, stock status, pricing trends, and customer satisfaction. With this data, you can spot resale-friendly brands that offer strong profit potential and are worth pursuing as wholesale partners.

• Brand Analyzer helps you determine whether a brand is suitable for resale and a good candidate to approach as a supplier.
• It streamlines the brand evaluation process by automating key research steps, saving you time when identifying profitable wholesale opportunities.
• The tool estimates a brand’s total monthly sales volume by aggregating revenue across its full product lineup.
• It reveals how often Amazon wins the Buy Box for that brand’s listings, helping you understand the level of direct competition.
• You can also see how many third-party FBA sellers typically compete on each product, giving you a clearer view of margin pressure and market saturation.
• Brand Analyzer shows the size of the brand’s catalog by listing how many products it carries, which helps gauge overall market presence.
• It assesses customer sentiment by analyzing the volume of reviews and average star ratings across the brand’s products.
• You’ll also get access to the average Buy Box prices, which supports better pricing strategy and profit estimation.
• For cost forecasting, it includes average FBA fees per product, so you can factor in fulfillment expenses more accurately.

Pros

• Data-backed decision-making

You’re not guessing  –  you’re choosing brands based on real sales data, competition levels, and profit estimates, which increases your chances of success.

• Direct brand access

Working directly with brands often leads to better pricing, fewer restrictions, and long-term partnership opportunities.

Cons

• Can be hard to get approved

Brands may be selective with resellers and often require proof of existing sales, strong business credentials, or specific volume commitments. Sometimes you might need to get ungated to sell certain products.

• Competitive outreach

Many sellers may be reaching out to the same brands, so standing out in your pitch and follow-up is essential.

Best for

Sellers who want to establish long-term brand relationships, avoid middlemen, and build a scalable wholesale operation with higher margins. This is a great way to improve your unit economics.

Note. Seller Assistant is a comprehensive product-sourcing software that helps Amazon sellers quickly find high-profit deals. It combines three extensions: Seller Assistant Browser Extension, and IP-Alert Chrome Extension by Seller Assistant, and VPN by Seller Assistant, Amazon seller tools: Price List Analyzer, Brand Analyzer, Seller Spy, Bulk Restrictions Checker, and API integrations, and features: Storefront Widget, Side Panel View,  FBM&FBA Profit Calculator, Quick View, Stock Checker, IP Alert, Variation Viewer, Sales Estimator, Offers, and Restrictions Checker.

It offers a robust toolkit of over 20 features built to streamline every part of the sourcing process  – from bulk scanning wholesale supplier sheets for high-margin leads to deep product research and advanced brand and competitor analysis. By using this FBA and FBM product sourcing software, you can easily identify products that have the potential to be sold well on Amazon.

Strategy 2. Find Verified U.S. Distributors with Sourcing AI

What it is

Sellers can now use AI-powered tools to find wholesale suppliers faster and more accurately than ever before. Sourcing AI by Seller Assistant does exactly that. It’s designed to help Amazon FBA wholesale sellers uncover verified U.S.-based distributors for specific brands  –  especially those with large-volume or authorized reseller programs. 

Built with real Amazon business workflows in mind, Sourcing AI mimics how experienced sellers source inventory: it searches structured product data and returns a table with key sourcing details like supplier name, product description, price, link, MOQ, and notes  –  streamlining the wholesale sourcing process from start to finish.

How it works

Start by visiting Amazon’s product page, search results, a competitor’s storefront, or the Seller Assistant Side Panel View. From there, click the “Sourcing AI” button and enter your request, such as: “Find suppliers of [Brand Name] in the U.S.”

Within seconds, Sourcing AI will return a detailed table of up to 10 matching suppliers, showing:supplier name, product description, price, direct link, Minimum Order Quantity (MOQ), and additional notes.

Each result is flagged as an exact or likely match, so you can focus your attention on the most credible sourcing opportunities.

What Sourcing AI does

Sourcing AI is built to help Amazon FBA sellers find real, profitable U.S.-based wholesale suppliers  –  fast. It follows Amazon seller logic and is packed with functionality designed for speed, precision, and sourcing confidence:

• Product matching by identifier

Finds exact or likely matches by using ASINs, UPCs, model numbers, or part numbers to locate the right products from suppliers.

• Verified U.S. suppliers only

Filters out international platforms like Alibaba, Temu, and eBay  –  focusing solely on trusted U.S. distributors and wholesale partners.

• Max COG filter

Automatically excludes suppliers whose prices exceed your defined maximum cost of goods  –  ensuring offers stay within your target margins.

• Detailed supplier table

Returns up to 10 results with essential details: Supplier name, Product Description, Price, Link, SKU, MOQ, and Match Confidence (Exact or Likely).

• Works directly from Amazon

Access Sourcing AI inside Seller Assistant’s toolkit:

• Amazon product pages (Seller Assistant)
• Search results (Quick View)
• Any supplier site (Side Panel View)
• Competitor storefronts (Storefront Widget).

• Warnings and prompts

Flags missing product data, potential bundles/multipacks, or low-confidence matches  –  so you can validate before taking action.

Pros

• Rapid, AI-powered sourcing

What normally takes hours of research is handled in seconds. Sourcing AI automates the discovery process and gives you ready-to-act supplier leads directly within your browser.

• Match confidence and price filters

The tool flags exact matches based on UPCs or model numbers and filters out suppliers who exceed your Max COG  –  helping you avoid mistakes and focus on profitable opportunities.

Cons

• Dependent on product data

If key identifiers like UPC or model numbers are missing from the Amazon listing, match confidence may drop, requiring manual review or validation.

• Supplier pricing not always real-time

While the tool pulls from public supplier websites, availability and pricing should still be confirmed before ordering, as they might not reflect live updates.

Best for

Wholesale FBA sellers looking to open new brand accounts through verified U.S. distributors. Also ideal for online arbitrage sellers and dropshippers needing fast, accurate sourcing options with margin filters.

Strategy 3. Source Through Authorized Brand Distributors

What it is

Instead of working directly with the brand, this strategy involves finding and partnering with one of the brand’s authorized distributors. These are third-party wholesalers officially approved to resell the brand’s products  –  often with lower minimum order quantities and more flexible onboarding terms.

How it works

Start by visiting the brand’s official website and checking for a “Where to Buy”, “Authorized Distributors”, or “Wholesale Partners” section. These pages typically list approved distributors by region or industry. Contact the distributors directly to inquire about opening a wholesale account, understand their resale terms, and request product catalogs or price lists.

Pros

• Easier access to products

Authorized distributors often have smaller MOQs and faster account approval than going directly through the brand, making them ideal for newer sellers.

• Guaranteed authenticity

Since these suppliers are vetted by the brand, you're ensured access to legitimate, high-quality inventory with minimal risk of IP claims or counterfeit issues.

Cons

• Fewer product options than brand-direct

Distributors may carry only a subset of the brand’s catalog  –  meaning you might miss out on exclusive items or latest releases.

• Pricing may be higher

Because distributors add their own markup, the wholesale prices may be slightly less competitive compared to ordering directly from the brand.

Best for

Sellers who want to sell branded products but may not meet a brand’s direct requirements (like high MOQs or established resale history). Great for building a diversified inventory without jumping through brand-level hoops.

Strategy 4. Leverage Existing Suppliers to Discover New Ones

What it is

Many wholesale suppliers distribute products from multiple brands  –  which makes them a valuable lead source for expanding your product catalog. By tapping into your existing supplier relationships, you can uncover additional brands or connected suppliers they already work with.

How it works

Once you’ve built a relationship with a supplier, they typically provide a price list covering all the brands they distribute. To identify new opportunities, scan this list for brands you haven’t sourced yet.

Use Seller Assistant's Brand Analyzer to evaluate each brand’s product range, revenue potential, competition, and resale eligibility. Based on that analysis, decide which additional brands are worth pursuing  – giving you a data-backed way to expand your inventory through a supplier you already trust.

Pros

• Low-friction expansion

Because you're already doing business with the supplier, they’re more likely to offer insights or help you access new brands with minimal onboarding.

• Builds a stronger supplier network

This strategy helps you move beyond isolated deals and create a network of vetted suppliers, improving your long-term sourcing flexibility.

Cons

• Manual analysis required

Even though you receive the full price list, identifying new opportunities still requires detailed product and brand analysis.

Tip. To automate separating good deals from dead inventory, you can use tools like Seller Assistant's Brand Analyzer and Price List Analyzer. Brand Analyzer helps evaluate the profitability and competitiveness of entire brands based on real Amazon data. Price List Analyzer matches supplier UPCs/EANs to ASINs and fills your spreadsheet with key metrics like profit, ROI, sales velocity, and restrictions – so you can instantly filter for winning deals and create a purchase shortlist. 

• Not all brands will be worth reselling

Some brands on the list may have poor profit margins, high competition, or Amazon dominance, making them unsuitable for your FBA strategy despite being readily available through your supplier.

Best for

Sellers who already work with one or more wholesale suppliers and want to deepen the relationship while expanding their brand access organically. Works especially well for niche-focused sellers looking for new product lines within the same category.

Strategy 5. Focus on a Specific Niche Market

What it is

Instead of targeting broad or oversaturated categories like electronics, home décor, or toys, this strategy focuses on selecting a narrow product niche with specific customer demand and lower competition. 

Examples of niche markets

Eco-friendly pet grooming supplies, tactical outdoor gear, allergy-safe snacks, or ergonomic accessories for remote workers.

By specializing in a focused category, sellers can better understand customer needs, spot underserved sub-niches, and tailor their sourcing strategy accordingly. Niche sellers often build stronger supplier relationships, face less direct competition, and enjoy better pricing leverage by becoming subject-matter experts in their space.

How it works

Choose a niche you're familiar with or that shows strong demand and profitability on Amazon. Use Sourcing AI, search engines and B2B directories to find U.S.-based distributors or wholesale suppliers that specialize in that segment. Because you’re targeting a defined market, it’s easier to tailor your outreach, negotiate terms, and build lasting relationships with specialized suppliers.

Pros

• Lower competition, better positioning

Focusing on a niche makes it easier to stand out and build expertise – reducing exposure to saturated markets and price wars.

• Stronger supplier fit

Niche distributors are often more responsive and supportive because they value working with sellers who truly understand their products and customers.

Cons

• Smaller product pool

Niche markets often have fewer available SKUs, which may limit how much inventory you can source from each supplier.

• Demand volatility

If demand shifts or trends fade, niche categories can lose momentum faster than broader categories – requiring consistent market research.

Best for

Sellers who want to specialize in a category, build domain authority, and work with suppliers that value focused, knowledgeable partners. Ideal for scaling up with precision rather than volume.

Strategy 6. Partner with Local and Regional Brands

What it is

Local and regional brands – especially small, family-owned businesses or niche manufacturers – often offer excellent wholesale opportunities for Amazon sellers. These brands may not be widely available on Amazon yet, giving you the chance to introduce unique, low-competition products to the marketplace while building direct supplier relationships.

How it works

Research regional brands in your target category using Google, local business directories, trade associations, or even Amazon itself. Focus on smaller “mom-and-pop” brands that are less likely to have a saturated seller base. 

Reach out via phone or email, introduce your business, and offer to become a reseller. These brands are often open to flexible deals and may be looking for new sales channels – especially if you already sell other products from their region or category.

Pros

• Less competition, unique listings

Since many local brands have limited Amazon presence, you can build exclusive listings or enjoy early-mover advantage with reduced competition. A good strategy is selling bundles on Amazon.

• Easier to negotiate

Small businesses are often more open to custom agreements, flexible minimums, and personal communication – making onboarding smoother and more collaborative.

Cons

• Limited scalability

Local brands may have smaller inventories, limited production capacity, or slower fulfillment processes – making them less suited for rapid scaling.

• Limited operational capacity

Many small or local brands may not have systems in place for high-volume orders, timely restocking, or frequent wholesale invoicing. This can lead to delays, communication gaps, or fulfillment challenges as your business scales.

Best for

Sellers looking to build a curated catalog of under-the-radar products with strong branding and low competition. Especially useful for those focused on region-based niches, handmade goods, or launching exclusive Amazon listings.

Strategy 7. Follow the Supplier’s Distribution Network

What it is

This strategy involves using your existing connections to trace supplier networks and discover additional Amazon FBA wholesale suppliers linked to brands or products you're already sourcing. Many suppliers are part of broader distribution chains – and tapping into those connections can unlock new sourcing channels that are pre-vetted and relevant to your product category.

How it works

Reach out to your current suppliers and ask about their upstream or downstream distribution partners. Some may work with larger wholesalers, regional reps, or manufacturers who serve multiple resellers. 

You can also investigate their product catalogs for clues about partner brands or distribution centers. This approach helps you uncover suppliers that might not show up in online directories but are trusted players in the supply chain.

Pros

• Built-in trust and legitimacy

Suppliers within the same distribution chain often operate under established agreements, reducing your risk of counterfeit or gray-market products.

• High relevance to your niche

Because they’re linked to your current inventory, these suppliers usually carry similar or complementary products – making them a natural fit for expansion.

Cons

• Information isn’t always shared openly

Some suppliers may be hesitant to disclose their network, especially if they see you as a competitor or if they lack strong relationships with their partners.

• Takes time to map out

Identifying and contacting relevant distributors through the network can be a slow, manual process – especially without introductions.

Best for

Sellers who already work with a few established suppliers and want to expand their sourcing by digging deeper into proven distribution networks. Especially effective for sellers who focus on consistent supply over trend-chasing.

Strategy 8. Use Wholesale Supplier Directories

What it is

Wholesale directories are curated databases of manufacturers, distributors, and Amazon FBA wholesale suppliers across various categories. These platforms offer an easy way to discover new sourcing partners without hours of individual research – especially when you're just starting or expanding into a new niche.

How it works

Sign up for reputable directories like SaleHoo, Worldwide Brands, or Wholesale Central. These directories let you filter suppliers by product category, location, MOQ, or shipping policy. Once you identify potential partners, you can contact them directly to request their catalogs, verify reseller terms, and begin building relationships.

• Useful for beginners

If you're new to wholesale sourcing, directories can provide a vetted, low-risk entry point into finding and evaluating suppliers across many product categories.

Cons

• Mixed supplier quality

While most directories vet their listings, not all suppliers offer competitive pricing, reliable inventory, or strong Amazon compatibility – so you still need to do due diligence.

• Limited exclusivity

Since many sellers access the same directories, it’s harder to secure exclusive deals or discover hidden opportunities through this method alone.

Best for

New and mid-level sellers looking for a wide range of wholesale options without deep supplier research. Ideal for those exploring new categories or building supplier diversity efficiently.

Strategy 9. Visit Trade Shows and Industry Events

What it is

Trade shows and B2B industry expos are powerful offline channels to meet Amazon FBA wholesale suppliers face-to-face. These events gather hundreds of manufacturers, distributors, and brand reps in one place – offering a rare chance to network, evaluate products hands-on, and build supplier relationships with high trust and speed.

How it works

Search for industry-specific trade shows in your product category (e.g., toys, beauty, home goods, or food) using platforms like 10times.com, TSNN, or ExpoGuide. 

Attend events prepared: bring business cards, your reseller documentation, and be ready to pitch your Amazon storefront as a valuable distribution partner. Use the opportunity to collect catalogs, ask about wholesale programs, and negotiate terms in real-time.

• Discover hidden and emerging brands

Cons

• Travel and attendance costs

Attending trade shows may involve travel, accommodation, and entry fees – which can add up, especially for smaller sellers.

• Limited follow-up success if unprepared

If you don’t come with a clear pitch, reseller documentation, or post-show follow-up plan, you risk losing the momentum of connections made during the event.

Best for

Sellers who are serious about scaling through exclusive brand relationships, discovering up-and-coming wholesale suppliers, or those looking to diversify beyond online sourcing methods.

Strategy 10. Use Curated Supplier Lists

What it is

For sellers who want a shortcut to finding verified Amazon FBA wholesale suppliers, curated supplier lists offer a fast-track solution. These lists compile pre-researched, trustworthy U.S. suppliers across multiple categories, allowing you to skip the discovery phase and jump straight into building relationships.

How it works

Seller Assistant offers a curated List of 500+ US suppliers. Simply select suppliers relevant to your category, request their price lists, and upload them into Seller Assistant’s Price List Analyzer to instantly identify profitable, reseller-friendly deals. You can apply filters for ROI, profit, restrictions, and sales velocity – eliminating hours of manual vetting.

Pros

• Saves research time

Instead of spending hours on Google or vetting unknown directories, you get immediate access to high-quality, resale-friendly suppliers.

• Compatible with bulk deal analysis

When combined with Price List Analyzer, you can instantly match supplier inventory to Amazon ASINs, check eligibility, and shortlist the best products for resale.

Cons

• Not fully exclusive

Other sellers may access the same supplier list, so competition is still possible – making product-level analysis crucial.

• Requires price list follow-up

You’ll still need to contact each supplier individually to request their pricing and verify account requirements before buying.

Best for

Busy or newer sellers looking to scale faster by working with pre-vetted Amazon FBA wholesale suppliers, without the upfront burden of sourcing from scratch.
