Search for "Amazon suppliers" and you get two very different questions tangled together: companies that want to sell their products to Amazon, and sellers on the marketplace looking for someone to make or supply what they list. This guide untangles the two and then concentrates on the second, because that is where most of the work sits. You will find the main sourcing routes, a checklist for evaluating a supplier against marketplace realities, and a practical process for samples, terms and second sources.
Key takeaways
- Selling to Amazon as a vendor and sourcing goods to sell on Amazon are separate problems; this guide covers sourcing.
- Your main routes are domestic wholesale, overseas manufacturing, private label and dropshipping, each with a different risk profile.
- Evaluate on unit economics after fees, packaging and labelling capability, lead time, quality consistency and capacity to scale.
- Order samples, agree terms in writing, and qualify a second source before a bestseller can strand you.
Two meanings of "Amazon suppliers"
The first reading is a business that supplies Amazon itself, selling stock to the retailer wholesale so Amazon owns the inventory and sells it on. That relationship is run on Amazon's terms, usually by invitation, and the practical advice is short: read Amazon's current published guidance for vendors and suppliers, prepare your commercial and compliance documentation, and expect a negotiation weighted towards a very large buyer. Anything more specific about programmes, terms or fees changes often enough that you should confirm it in Amazon's own seller and vendor documentation rather than trust a summary written elsewhere.
The second reading, and the one most people mean, is the supplier who provides the goods you sell as a third-party seller on the marketplace. Here you are the buyer. You choose the factory or wholesaler, you set the specification, you carry the inventory risk, and you live with the consequences of a bad choice in the form of returns, poor reviews and dead stock. That is a classic procurement problem wearing an e-commerce hat, and it rewards the same discipline any professional buyer would apply.
The distinction matters because the advice does not transfer. Pitching Amazon as a vendor is a sales exercise. Sourcing product to sell on Amazon is a buying exercise, with samples, unit economics, lead times and supplier risk at its centre. Everything that follows assumes you are the buyer.
The main sourcing routes for marketplace sellers
There is no single best channel. The right route depends on your capital, your tolerance for lead time, and whether you are reselling an existing brand or building your own. Most established sellers end up using more than one, so treat these as options to combine rather than a menu you pick once.
- Domestic wholesale and distribution. Buying branded goods from an authorised wholesaler or distributor in your own market gives short lead times, easy returns and simple paperwork, at the cost of thinner margins and competition from every other seller on the same listing.
- Overseas manufacturers. Going direct to a factory abroad usually gives the lowest unit cost and the most control over specification, but adds freight, duty, longer lead times and a much heavier verification burden before the first order.
- Private label. A manufacturer produces a product under your brand, which lets you own the listing and build equity rather than fight on price, provided you can fund tooling, packaging design and a meaningful first run.
- Sourcing agents. An agent shortlists factories, checks quality and manages shipping on your behalf, which is valuable when you cannot travel or inspect yourself, though you pay for the service and inherit their supplier bias.
- Dropshipping. The supplier ships directly to your customer, so you hold no stock, but you also hand them control of dispatch speed, packaging and defect rates, which is a fragile arrangement on a marketplace that judges you on exactly those things.
Dropshipping deserves the caution. It is attractive because it needs almost no capital, but on a marketplace your account health depends on late-dispatch rates, cancellations and customer complaints that your supplier controls and you cannot see coming. Amazon also has its own published rules about drop shipping arrangements, so check those in the current seller documentation before you build anything on the model. If you do pursue it, the supplier vetting in our guide to dropshipping suppliers is the minimum standard, not the optional extra.
Unit economics that survive marketplace fees
The most common sourcing mistake is judging a supplier on their quoted unit price. On a marketplace, the quoted price is only the first line of the sum. Between it and the money that reaches your account sit referral and fulfilment charges, inbound freight, customs duty, packaging and labelling, storage, advertising to get the listing seen, and refunds on the units that come back.
Build the calculation backwards. Start with the price the market will realistically bear for your product, subtract every one of those costs, and see what remains. Amazon publishes its current fee schedules and calculators in its seller documentation, and those are the numbers to use, because fee structures are revised and a stale figure will quietly wreck a spreadsheet. If a product only clears a profit when every cost lands at its best case, it is not a viable product.
Then stress the model. Ask what happens if freight rates rise, if the exchange rate moves against you, if advertising cost per sale climbs as competitors arrive, or if your return rate doubles. A supplier whose price still leaves a workable margin under those conditions is worth far more than one who is marginally cheaper today. Headroom is what lets you run a promotion, absorb a bad batch or ride out a slow quarter without selling at a loss.
How to evaluate a supplier for marketplace selling
Score every candidate on the same criteria so your comparison is genuine rather than a preference for whoever answered fastest. These are the factors that decide whether a supplier works specifically for selling on a marketplace, as opposed to any old wholesale relationship.
| Criterion | What to check | Why it matters on a marketplace |
|---|---|---|
| Landed unit cost | Price at your real volume, plus freight, duty and packaging | Decides whether any margin survives once fees are deducted |
| Packaging and labelling | Barcodes, carton marks, inserts, compliance labels | Non-compliant inbound stock gets delayed, charged or rejected |
| Lead time and reliability | Production days, shipping mode, on-time record | Long or erratic lead times turn a sales spike into a stockout |
| Quality consistency | Variation between batches, defect rate, inspection regime | Returns and negative reviews cost more than the units themselves |
| Capacity to scale | Free capacity, other clients, response to a volume jump | A supplier who cannot grow with you caps your bestseller |
| Compliance documentation | Test reports, certificates, safety and material paperwork | Category requirements must be evidenced, not assumed |
| Communication | Response time, clarity, willingness to answer awkward questions | Problems get solved at the speed your supplier replies |
Weight the rows to suit the product. For a fragile or regulated item, quality consistency and documentation dominate. For a commodity in a crowded category, landed cost and lead time carry more weight. Whatever the weighting, record the scores and the evidence behind them, because a written comparison is what lets you revisit a decision months later without relying on memory.
Samples, verification and inspection
No amount of correspondence substitutes for holding the product. Order samples from every shortlisted supplier and judge them against the listing you intend to publish, not against each other. Where possible, ask for samples from different production runs so you can see variation rather than the single polished unit a supplier keeps for visitors.
The product
Does it match the specification, feel like the quality your price implies, and survive the handling a courier will give it?
The packaging
Can the supplier apply your barcodes, labels and carton markings correctly, and is the retail pack fit to arrive undamaged?
The paperwork
Do the test reports, certificates and material declarations actually exist, name this product, and stand up to a check?
The business
Is the company registered, does the address resolve to a real facility, and are they the maker or a trading intermediary?
For a first production order of any size, arrange an inspection before the goods ship. A third-party inspector checking a random sample against an agreed specification at the factory is inexpensive relative to a container of unsellable stock, and the knowledge that inspection happens tends to improve what gets produced. Verification habits are the same ones covered in our guide to vetting suppliers on Alibaba, and they apply to any supplier you have not met.
Test the response, not just the sample. Raise a deliberate query mid-order: a small specification change, an awkward question about capacity, a request for a document. How quickly and how honestly a supplier answers when something is inconvenient predicts how they will behave during your peak season far better than the quality of the sample they chose to send you.
Negotiating minimums, price breaks and terms
Minimum order quantities are usually more flexible than the first quote suggests, particularly for a first order a supplier treats as a trial. Ask for a reduced initial run in exchange for a commitment to a larger follow-up, or accept a slightly higher unit price on the smaller quantity so you can validate demand before committing serious capital. A supplier who refuses any accommodation on a first order is telling you how the relationship will feel later.
Get the commercial terms written down, even if the agreement is only a clear email both sides can point to. Cover the unit price and the volumes that trigger price breaks, payment terms and deposit, the shipping term that defines who pays and who carries risk at each stage, lead times for repeat orders, the agreed quality standard and what happens when a batch fails it, and how packaging and labelling changes are handled. Ambiguity is where disputes grow, and the moment to remove it is before an order goes wrong.
Treat the first order as the beginning of a relationship rather than a transaction. Reliable suppliers give their best lead times, flexibility and price movement to customers who pay on time, forecast honestly and do not renegotiate every invoice. Being an easy customer is a genuine commercial advantage, and it costs nothing beyond a little organisation.
Dual sourcing and supply risk
A single supplier is simple until it is not. Factories lose staff, raise prices, get bought, deprioritise small accounts or simply stop replying. On a marketplace the penalty for that arrives quickly, because a listing that goes out of stock loses the ranking and momentum it took months to build, and reclaiming it costs more than holding it did.
Once a product earns meaningful revenue, qualify a second source for it. That means running the same evaluation, ordering samples and, ideally, placing a real if modest order so the backup is proven rather than theoretical. Splitting volume unevenly, with the bulk to your primary and a steady trickle to the secondary, keeps the second relationship warm without fragmenting your buying power. This is standard practice in global sourcing for exactly the reason it applies here: concentration is efficient right up to the moment it is catastrophic.
Pair dual sourcing with a sensible inventory buffer. Work out how long a replacement order genuinely takes from purchase order to receipt, including production, freight and inbound processing, and hold enough cover to survive that window plus a margin for the delays that always appear at the wrong time of year.
Keeping supplier management organised as you scale
One product and one supplier fit comfortably in a spreadsheet and your head. Twenty products across six suppliers, each with different lead times, price breaks, documents and quality histories, do not. The sellers who scale well are the ones who put structure around supplier information early, before the mess makes it expensive to fix.
In practice that means a single record per supplier holding contacts, agreed terms, certificates and their expiry dates, purchase order history and a running note of quality issues and how they were resolved. It means purchase orders raised consistently and matched against what arrives, so you can see who ships late and who ships short. Over a year, that record is what turns a set of impressions into evidence you can negotiate with.
That is the ground ProcureWave is built for: keeping supplier records, purchase orders, approvals and performance history in one place so buying decisions rest on what actually happened rather than on recollection. If you are moving from a handful of products to a catalogue and want the supplier side to stay manageable, get in touch and we will talk through how other growing sellers have set it up.
Frequently asked questions
Does "Amazon suppliers" mean suppliers to Amazon or suppliers for Amazon sellers?
It is used both ways. Some people mean companies that sell their goods to Amazon itself as a wholesale vendor, which is an invitation-led arrangement Amazon manages on its own terms. Most people asking the question are third-party sellers looking for suppliers to stock the products they list on the marketplace. This guide focuses on the second reading, because that is the sourcing decision you actually control.
Where do most Amazon sellers find their suppliers?
Common routes are domestic wholesalers and distributors, overseas manufacturers found through B2B marketplaces or sourcing agents, trade shows, and referrals from other sellers. Each route trades cost against control and lead time. The broad, build-a-longlist-then-filter method in our guide to how to find suppliers works just as well for marketplace sourcing as it does for corporate buying.
How do I know if a supplier price leaves me a profit on Amazon?
Work backwards from your realistic selling price and subtract every cost that lands between it and the supplier invoice: marketplace and fulfilment charges, inbound freight and duty, packaging and labelling, advertising, storage and a genuine allowance for returns. Check the current fee schedules in Amazon's own seller documentation rather than a figure you read on a forum, because they change.
Should I ask a supplier for samples before ordering?
Always, and more than one. Order samples from each shortlisted supplier, ideally from separate production runs, and judge them against the listing you intend to publish rather than against each other. Samples reveal quality, finish, packaging and the supplier's willingness to cooperate, all of which are far cheaper to discover now than after a full container arrives.
Is one supplier enough, or should I dual source?
One supplier is simpler while you are proving a product. Once an item earns real revenue, qualify a second source for it. A stockout on a ranked listing costs sales and momentum that take time to rebuild, so the insurance is usually worth the extra qualification work, even if the backup only ever receives a modest share of your volume.
