FBA sellers source profitably from brand-direct accounts, regional distributors, and curated B2B marketplaces that provide verified authorization.
The wholesale distributor you pick decides three things at once: your gross margin, your restock reliability, and your defense file when Amazon asks where the product came from. Most sellers chase the first and ignore the third — until a single inauthentic complaint freezes a listing. This guide walks through the categories of distributors that actually work for Amazon FBA, what each one costs in money and effort, and how to evaluate fit before you open an account.

The Four Categories of Wholesale Sources for FBA
Not every “wholesale” supplier is treated equally by Amazon. The category matters more than the brand name on the invoice.
1. Brand-direct accounts. You buy from the manufacturer or brand owner. This is the cleanest paper trail and the only source that reliably produces an authorization letter Amazon will accept during a section 3 review. Minimums vary — a small CPG brand might open an account at 500 dollars, while a larger consumer electronics brand may require 10,000 dollars or a signed MAP agreement.
2. National master distributors. Companies like KeHE (natural and specialty grocery), McLane (convenience), and Bunzl (packaging and away-from-home) carry tens of thousands of SKUs. They sell to FBA sellers when you meet their license and volume requirements, but the invoices are sometimes contested by Amazon if the brand has not explicitly authorized resale on the platform.
3. Regional and category distributors. Smaller distributors focused on a single region or category — pet, beauty, gourmet food, hardware. These are easier to open accounts with, often willing to drop ship, and frequently represent emerging brands the big distributors ignore.
4. Curated B2B marketplaces. Platforms like Catalist AI, Faire, Mable, and Pod Foods aggregate emerging brands behind a single login. The pitch is discovery speed: instead of cold-emailing 200 brands, you browse approved suppliers and place opening orders in one cart. Authorization status varies by brand and platform, so verify before listing on Amazon.

A working FBA wholesale operation usually blends two or three of these. A typical mature account has 8 to 15 brand-direct accounts for hero SKUs, one or two regional distributors for fill-in volume, and a marketplace login for sourcing emerging brands before competitors find them.
Comparing the Main Distributor Options
| Source type | Typical minimum | Margin range | Amazon authorization | Best for |
|---|---|---|---|---|
| Brand-direct | $500–$10,000 | 25–40% | Strongest, letter on request | Hero SKUs and ungating |
| National distributor (KeHE, McLane, Bunzl) | $2,500+ | 12–22% | Variable, brand-dependent | Volume restocks |
| Regional / category distributor | $250–$2,000 | 18–28% | Usually acceptable | Fill-in and niche categories |
| Curated B2B marketplace | $100–$500 | 20–35% | Brand-dependent | Discovery of emerging brands |
| Liquidation (Direct Liquidation, B-Stock) | $500–$5,000 | Variable | Risky for branded goods | Bulk closeouts only |
The “best” distributor is the one that matches your category, capital, and risk tolerance. A grocery FBA seller doing 200,000 dollars a month will live inside KeHE and UNFI. A beauty seller scaling to six figures will source most volume from brand-direct accounts. A new seller testing categories should start with curated marketplaces to keep opening orders small.

One note on liquidation: pallets from B-Stock, Direct Liquidation, and Quicklotz can produce great margins, but Amazon increasingly rejects liquidation invoices during authenticity reviews on branded items. Use this channel for non-branded or for selling outside Amazon.
How to Evaluate a Distributor Before You Order
Before you wire money to any distributor, run them through five checks. This is the work that separates a sustainable wholesale account from a one-time stockout that ties up cash for 90 days.
Authorization clarity. Ask directly: “Does the brand authorize resale on Amazon, and will you provide a letter on brand letterhead if Amazon requests one?” A yes that comes with documentation is the answer. A vague “you should be fine” is a no.
Invoice format. Amazon wants invoices showing your business name, the supplier’s business name and address, the brand name printed on the document, item descriptions matching the ASINs, and a date within the last 365 days. Ask for a sample invoice before placing an order.
MAP enforcement. Minimum advertised price policies dictate whether you can profitably sell after Amazon fees. A category with strict MAP enforcement and 25 percent wholesale margins usually leaves 8 to 12 percent net after FBA fees, returns, and storage — workable at volume, painful at low velocity.
Restock reliability. Out-of-stock on a hero SKU costs you BSR rank and Buy Box history. Ask the distributor about typical lead times, backorder rates over the past six months, and whether they hold inventory or drop-ship from the brand.
Account terms. Net 30 terms unlock cash flow. Most distributors require three to six months of order history before extending terms, but ask upfront so you know the path. Credit card payment with two percent cash back can also fund float without paperwork.

The math: a 20 dollar product bought wholesale at 11 dollars, sold at 24.99, pays roughly 3.75 in referral fees, 5.40 in FBA fulfillment, and 0.30 in storage. Net is about 4.54 dollars per unit, or 18 percent. That is a healthy FBA wholesale margin. If your numbers come in below 12 percent net, the SKU is too competitive or the distributor pricing is not real wholesale.
Where Catalist Fits and What to Do Next
Catalist AI is a B2B marketplace built around emerging consumer brands — the kind of brands that have product-market fit but have not yet signed with national distributors. For FBA sellers, that matters because emerging brands are where margins are healthiest and competition is thinnest. Lower seller count on a listing means more Buy Box share. Direct relationships with brand owners mean authorization letters arrive in a day, not a week.
The trade-off is operational. Sourcing emerging brands requires more SKU-level diligence: pulling Keepa graphs, checking brand registry status, confirming the brand has not enrolled in Amazon Brand Gating, and forecasting demand on listings with shorter sales history. The upside is the same as the upside in any market — being early.
If you are an independent retailer or FBA seller looking for emerging consumer brands with clear authorization and clean invoicing, Apply to Join Catalist. We approve buyers with active resale certificates and a real sourcing track record, then route you to brands that fit your category and volume.
