How do I find wholesale suppliers for Amazon?

Buy from authorized distributors, go brand-direct to manufacturers, or use legitimate wholesale marketplaces. Find them through brand 'where to buy' / 'become a retailer' pages, industry trade shows and directories, and distributor catalogs. Avoid retail arbitrage sites and marketplaces posing as wholesale — Amazon wants invoices from real authorized distributors, especially for ungating.

What are the best wholesale suppliers for Amazon?

There's no single best supplier — the best one for you is a legitimate, authorized source whose catalog contains products that are profitable after Amazon fees, actually sell (good sales rank), and that your account can list (not gated). A supplier with great prices on gated or slow-moving brands is worthless; one with a handful of profitable, listable products is gold.

Do I need a resale certificate to buy from wholesale suppliers?

Most true wholesale suppliers require a business (EIN) and a resale/sales-tax certificate to open an account and sell to you tax-exempt at wholesale pricing. A resale certificate is issued by your state and is quick to obtain. Some smaller wholesalers sell with no account or minimum.

How do I know a wholesale supplier's products will be profitable on Amazon?

Match each product to its Amazon listing by UPC or ASIN, subtract Amazon referral and FBA fees, shipping, and prep from the current Buy Box price, and check the sales rank and your listing eligibility. Most of a supplier's catalog usually isn't profitable; the value is in finding the few products that are before you place an order.

Wholesale Suppliers for Amazon Sellers

Updated August 2026 · ~7 min read

Finding wholesale suppliers for Amazon isn't the hard part — finding legitimate ones whose products you can actually profit from is. Here are the main types of wholesale suppliers, how to tell a real one from a reseller in disguise, and how to know which of their products are worth buying for Amazon.

What counts as a real wholesale supplier

A true wholesale supplier is an authorized distributor or the manufacturer itself — a source Amazon recognizes and that issues proper invoices. That distinction matters: Amazon asks for wholesale invoices from authorized distributors when you request approval to sell (getting ungated), and receipts from retail stores or online marketplaces don't qualify.

The main types of wholesale suppliers for Amazon

1. Authorized distributors

Mid-point between the brand and the retailer, carrying many brands across a category (grocery, beauty, housewares, pet, office). They usually require a business account and a resale certificate, and they're the backbone of most wholesale Amazon operations.

2. Brand-direct (the manufacturer)

Buying straight from the brand removes the middleman's markup, so margins are best — but brands often have higher minimums and their own approval process. This is where opening direct accounts pays off over time.

3. Wholesale marketplaces & directories

Online wholesale marketplaces and supplier directories aggregate many small suppliers in one place. Useful for discovery, but vet each supplier individually — some list at near-retail prices, and not everything on a "wholesale" marketplace is genuinely wholesale.

4. Liquidation & closeouts (with caution)

Overstock and returns can be cheap, but quantities and condition vary, and Amazon may not accept liquidation invoices for ungating. Treat it as opportunistic, not a foundation.

How to spot a legitimate wholesale supplier

They ask for your business details and resale certificate — a sign they sell true wholesale, tax-exempt.
They provide real invoices with their business name, your details, and dates.
Pricing is meaningfully below retail, not a few percent off.
They carry brands with real UPCs that match Amazon listings.

Red flag: a "wholesaler" that sells to anyone with no business account, at prices barely below Amazon's, is usually a reseller — and their invoices won't help you get ungated.

The real problem: most of the catalog won't be profitable

Even with a great supplier, the majority of any catalog loses money on Amazon once you subtract Amazon's fees, or the brand is gated, or the item barely sells. The winning move isn't finding a supplier — it's finding the handful of products in each supplier's catalog that are profitable, in demand, and listable for your account.

Vet before you buy: for every candidate confirm (1) it's profitable after fees, (2) it sells — a healthy sales rank, and (3) your account can list the brand.
