If you sell on Amazon or Walmart, you’ve probably seen the same products available at very different prices from very different kinds of suppliers. Some come from authorized distributors. Others come from the secondary market — closeouts, overstock, and liquidation. Both can be legitimate ways to source genuine branded goods, but they work differently, and the differences matter for your invoices, your account health, and how you handle a complaint if one ever lands. This guide walks through it plainly so you can decide what fits your business.
What “authorized distribution” actually means
An authorized distributor has a direct relationship with the brand or manufacturer. The brand has signed off on them reselling its products, often within a defined territory or channel. When you buy from an authorized distributor, you’re buying inside the brand’s official supply chain — and in some programs the brand may extend that status to you, for example by granting reseller approval or listing you as an approved seller.
The upside is tidy alignment with the brand. The trade-offs are real, though: authorized programs frequently come with minimum order volumes, application and approval steps, channel restrictions (some brands prohibit selling on marketplaces at all), MAP pricing rules, and thinner margins because everyone is buying at a controlled price. For many products and many sellers, authorized distribution simply isn’t open, available, or economical.
What “secondary-market wholesale” actually means
The secondary market is where genuine inventory moves outside the brand’s primary distribution path. This is overstock a retailer over-ordered, closeouts on discontinued packaging or seasonal SKUs, shelf-pulls, and liquidation lots. The goods are real, brand-name products — they just took a different route to you.
Here’s the honest part, and it’s important: buying genuine goods on the secondary market does not make you an authorized reseller of that brand. The product is authentic. Your authorization status is a separate question, and for most secondary-market sourcing the answer is simply “not authorized.” That’s not a scandal — a large share of healthy Amazon businesses run this way — but you should understand it rather than assume a distributor relationship gives you brand authorization. It doesn’t, on its own.
What this means for invoices
Wherever you source, keep clean, complete documentation. A good wholesale invoice should show the supplier’s real business name and contact details, your business name, the actual product descriptions, quantities, and dates. Reputable secondary-market distributors — Groovin Fulfillment included — provide proper invoices for the inventory you buy.
What an invoice proves is that you bought genuine product through a real, traceable transaction. That’s exactly the kind of documentation Amazon tends to look for when it asks you to verify a supply chain. What a standard secondary-market invoice does not do is establish that the brand authorized you to sell. Those are separate documents and separate claims. Don’t represent an invoice as something it isn’t.
What this means for IP complaints and authenticity
It helps to separate two kinds of complaints, because sellers often blur them:
- Authenticity / counterfeit complaints allege the product isn’t real. If your goods are genuine and you have invoices tracing them to a legitimate supplier, that documentation is your strongest response. It can help, though nothing is guaranteed — outcomes depend on your account, your records, and Amazon’s review.
- Intellectual-property or “unauthorized seller” complaints are different. Some brands file these to limit who sells their products, even when the goods are 100% genuine. Selling authentic product does not automatically resolve this type of complaint, because the issue raised is about permission, not authenticity.
This is the practical reality of secondary-market sourcing, and we’d rather you hear it straight: it’s a sound, widely-used model, but it doesn’t make you immune to brand-gating or IP enforcement. Many sellers manage this well by choosing products and brands that are friendlier to third-party sellers and by keeping their paperwork airtight.
A quick word on LOAs and brand authorization
You’ll see “LOA” (Letter of Authorization) mentioned a lot online, sometimes as if it’s a routine attachment to any wholesale order. It isn’t. Brand authorization and LOAs are only relevant on select, usually larger deals, and they never come standard with secondary-market inventory. If a specific opportunity genuinely calls for it, that’s a separate conversation — not a default expectation. Treat any supplier promising blanket “guaranteed ungating” or automatic authorization with healthy skepticism.
How to source responsibly
- Know your supplier. Work with distributors who use a real business name, can be contacted, and issue proper invoices. Vague sellers and “DM me for a list” sources are a risk.
- Keep every invoice. Store documentation by purchase so you can produce a clean record on request.
- Vet the brand, not just the price. Before you commit, check whether a brand is known for aggressively gating or filing IP complaints against third-party sellers. A great margin on a hostile brand can become a headache.
- Diversify. Don’t bet your whole catalog on one SKU or one brand that could restrict you overnight.
- Inspect and prep properly. Genuine goods still need to arrive in sellable condition. Accurate FNSKU labeling, poly bagging, and bundling protect your reviews and your inventory performance — this is where a prep partner earns its keep.
The bottom line
Authorized distribution and secondary-market wholesale are both legitimate. Authorized distribution buys you closer brand alignment at the cost of access, volume requirements, and margin. The secondary market gives you genuine branded inventory at better economics, with the honest caveat that you’re typically not brand-authorized — so your invoices and brand selection do a lot of the heavy lifting. Source from real suppliers, keep clean records, choose your brands wisely, and you can build a durable business on the secondary market with your eyes open.
