To source products to sell on Amazon under your own brand, you do three things: find a manufacturer, get the product made to your spec, and land it in FBA ready to sell.
That puts the whole weight on sourcing. Pick the right factory and the business has a foundation under it. Pick wrong and everything downstream wobbles: quality, margin, reviews, all of it. Here is how to source it properly, from the first product decision to your first shipment.
How to source a product for Amazon, step by step
The path stays the same even as the product changes. If private label is new to you, start with what private label manufacturing is, then come back here for the sourcing.
Start with the product and the numbers
Pick the product before the factory, and pick it on demand and margin. Find something people are already buying, then check whether the math survives Amazon’s cut. Referral fees often run into the mid-teens percent by category, and FBA adds fulfillment and storage on top. If it only pencils out at a perfect price, it does not pencil out.
Run the numbers on landed cost, not the factory quote. Your real cost per unit is the ex-works price plus freight, duties, and any tariffs, before Amazon takes its share. A product that looks cheap on the quote can turn unprofitable once it is sitting in a US warehouse.
This is where knowing how to find products to sell online really starts. Not with a supplier’s catalog, but with a real gap you can fill and defend.
Find a manufacturer you can trust
This is where most first-timers lose months. You have a few channels, and each has a tradeoff. Online marketplaces like Alibaba give you huge selection and low friction, and no easy way to tell a real factory from a trading company reselling someone else’s line. Trade shows put products in your hands, but cost time and travel. Sourcing agents can open doors, though plenty quietly take a cut from the factory, which puts them on the factory’s side, not yours.
The channel matters less than the verification. Anyone can send a quote. The real work is confirming a factory makes what it claims, at the quality and volume you need, and is not passing your order to a workshop you never see. Being on the ground where the product gets built is what separates a real check from a polished video call. That is the core of what our sourcing work covers.
So verify before you commit. Ask for the business license and check that it matches the company you are dealing with. Ask for references and current clients, then actually contact them. Order samples from the real production line, not a showroom.
Treat a factory that dodges a video walkthrough of its floor as a red flag, and better still, have someone stand in the building. A trading company can fake a catalog. It cannot fake a floor.
The logic holds off Amazon too. Whether you are selling there or working out how to find a product to sell on Shopify, you are still finding a manufacturer and making the product yours.
Prove the product before you commit
Order samples and lock the spec before any bulk order. Approve a physical unit, write down exactly what the production run has to match, and get it in writing with the factory. A perfect sample followed by a wrong bulk run is the oldest story in sourcing. A tight spec is how you stop it.
Pin down terms and protect your design
Before the deposit leaves your account, settle the terms in writing. Agree the payment structure, usually a deposit up front and the balance before the goods ship, so you are never fully paid out on an unfinished run. Confirm who owns the tooling and molds, because if the factory owns them, you are tied to that factory. And put an NDA in place, so the supplier cannot turn around and sell your product to the next buyer who walks in.
Clear compliance for your category
Amazon enforces product rules, and your category decides which ones apply. Anything ingested or applied to the body brings FDA requirements. General and children’s products fall under CPSC safety rules. Electronics need FCC authorization. Sort this before production, not at customs, because a compliance miss can pull your listing or strand your inventory.
Plan MOQ, cash, and QC
Factories set a minimum order quantity, and it ties up cash before you have sold a single unit. Many will flex that minimum for a first order if you ask, especially when you are clear about reordering. Plan the first order against what you can actually fund.
Then build quality control into the run, not one look at the end. Catching a defect at 20 percent of the run is a fix. Catching it after the container ships is a write-off. In practice that means checks during production and a pre-shipment inspection before you release the balance, so problems surface while the factory can still fix them.
Get your units into FBA
Last comes freight, customs, and delivery into Amazon’s network. Your goods clear import and land in FBA ready to sell, not ready to troubleshoot. Handled together, spec to delivery, this is what our product launch work runs end to end.
When to source it yourself, and when to bring in a partner
Straight answer: you do not always need help. A small first order of a simple product, you can source from your laptop. Order samples, ask the right questions, stay careful, and you can get there.
You start needing a partner when the stakes climb. A product made overseas with no one on the ground where it is built. A catalog growing faster than you can track suppliers. Or a first run that went wrong and taught you what a bad factory actually costs. That is when someone who sources and runs production for a living earns the fee.
If your first product is simple and you want to learn the ropes yourself, do it. A partner is for when sourcing becomes the thing that makes or breaks the launch.
Where Helix comes in
If you are building a product to sell on Amazon, sourcing is the part that decides whether it works. That is what we run at Helix.
We find your manufacturer, vet it on the ground in China, manage production with QC at every stage, and clear compliance for your category. Then we ship the first batch, into FBA when that is where it needs to go. You approve the samples. We handle the rest.
The track record behind that: 18 brands launched, 800+ verified suppliers, our own team in China with 15+ years in local manufacturing, and zero commissions from suppliers. When we negotiate, we are negotiating for you, not quietly earning a cut from the factory.
Tell us what you want to sell, and we will tell you straight what it takes to source and launch it.
Frequently asked questions
Where do Amazon sellers get their products?
The sellers building a real brand have their products manufactured to their own spec, usually overseas by a factory they have vetted. That means finding a manufacturer, proving the product with samples, and running production under quality control. It is more work upfront, and it is the version that builds something you own.
How long does it take to source a product for Amazon?
Finding a verified manufacturer can take around 6 weeks on its own. Samples, the production run, and freight add more on top of that. Plan in months, not weeks, to a first shipment, and treat anyone promising an overnight factory with suspicion.
How much does it cost to start sourcing a product for Amazon?
It depends on the product and the factory’s minimum order quantity, which ties up cash before your first sale. Samples, tooling, compliance, and freight add to it. The number that matters most is not the entry cost, but what a bad supplier or a failed production run would cost you later.
