Here's a trap beginners fall into constantly: they find a supplier, buy inventory, try to get ungated — and Amazon rejects their invoice. The reason? They bought from a retailer pretending to be a distributor, or a wholesaler that isn't authorized by the brand.
Before you spend a dollar on inventory, you need to understand who you're actually buying from. The difference between a wholesaler and a distributor isn't just semantics — it changes what you can sell, what Amazon will accept, and how much you pay.
The Supply Chain in Plain English
Products don't teleport from the factory floor to Amazon's warehouse. They move through layers:
- Manufacturer — makes the product
- Distributor — buys huge quantities directly from the manufacturer, often exclusively
- Wholesaler — buys from distributors (or sometimes manufacturers) and resells in smaller bulk quantities
- Retailer — sells individual units to consumers (Target, CVS, Walmart, etc.)
- You — the Amazon seller, buying somewhere in the middle
The closer you are to the manufacturer, the lower your cost and the cleaner your sourcing chain.
What Is a Distributor?
A distributor has a formal, direct relationship with the brand or manufacturer. They're often authorized — meaning the brand has specifically approved them to sell its products downstream.
Authorized distributor invoices are what Amazon actually wants when you apply to sell a gated brand. A random wholesale website's invoice often won't cut it.
Distributors typically:
- Buy in large volumes (often truckloads or container quantities)
- Have exclusive or semi-exclusive territory agreements with brands
- Appear on the brand's official “find a distributor” page
- Provide invoices that include their own address, the brand's products, and a verifiable paper trail
Examples: UNFI (food and natural products), McLane (convenience store goods), Cardinal Health (medical supplies). These aren't names you'll Google casually — you find them by calling brands directly and asking who their authorized distributors are.
What Is a Wholesaler?
A wholesaler is a middleman who buys products (often from multiple distributors or manufacturers) and resells them in smaller bulk quantities. They're the most accessible option for new sellers.
Wholesalers typically:
- Carry hundreds or thousands of brands in one catalog
- Have lower minimum order quantities (MOQs) than distributors
- Are easy to find — many have open applications online
- May or may not be authorized by the brands they carry
This last point is critical. Just because a wholesaler carries a brand doesn't mean they're authorized to sell it. Always verify with the brand directly before buying to resell.
Examples: Faire (boutique goods), DollarDays, Wholesale Central. These are accessible starting points — but do your homework on brand authorization before buying.
The Difference That Actually Matters for Amazon Sellers
Here's what separates them in practice:
- Who authorizes them? Distributors: the brand directly. Wholesalers: varies — often no one.
- Invoice quality: Distributors: clean, verifiable, Amazon-friendly. Wholesalers: often fine, but varies.
- Access: Distributors: harder to get accounts with. Wholesalers: usually easy to sign up.
- Price: Distributors: lower (fewer middlemen). Wholesalers: slightly higher margin taken out.
- Brand variety: Distributors: usually fewer, more specialized. Wholesalers: often hundreds of brands.
Bottom line: distributors are more powerful, harder to access, and cleaner for Amazon compliance. Wholesalers are your practical starting point — but verify authorization before you buy.
What Amazon Actually Wants (And What It Rejects)
When you apply to sell a gated brand or category, Amazon asks for a supplier invoice. Here's what gets rejected:
- Receipts from retail stores (CVS, Walmart, Target are not distributors)
- Invoices from unauthorized wholesalers
- Invoices with quantities under 10 units (Amazon wants to see you're buying in bulk, not retail)
- Invoices that don't match the brand's authorized supply chain
The safest path: call the brand. Ask them who their authorized distributors are. Then buy from that distributor. That's the invoice Amazon trusts.
How to Find the Right Source for Your Product
Three starting points that actually work:
- Call or email the brand directly. Ask: “Can you share a list of your authorized distributors?” Most brands will tell you. This is the golden path.
- Check the brand's website. Many brands have a “Where to Buy” or “Find a Distributor” page. That list is your shortlist.
- Trade shows. Events like ASD Market Week or Natural Products Expo put you in front of distributors and brands in one room. Worth attending if you're serious.
For wholesalers, you can start at Faire, Wholesale Central, or DollarDays — but treat their catalog like a lead list, not a guaranteed green light to sell everything in it.
One More Thing Most Beginners Miss
You can buy from a wholesaler AND still get burned — not because the wholesaler is shady, but because the brand hasn't authorized that channel for Amazon sales. Some brands actively restrict third-party Amazon selling. A quick call to the brand before your first order can save you from a suspended listing and locked-up inventory at an FBA warehouse.
Know your supply chain before you open your wallet. It's the single most overlooked step in sourcing — and the one that causes the most beginner headaches.
Your Action for Today
Pick one product or brand you're interested in sourcing. Google “[brand name] authorized distributor” — and then call or email the brand to confirm. That single conversation will tell you more about whether you can profitably sell that product than any spreadsheet will.
