Fulfilment by Amazon lets you send inventory to Amazon’s warehouses and have them handle storage, packing, shipping, returns and customer service. Your products become eligible for fast shipping programmes, which substantially improves conversion.

It is a genuine business model with genuine failures. The failures are almost always about arithmetic rather than effort.

How the model works

You source or manufacture a product, ship it to an Amazon fulfilment centre, and list it. When a customer orders, Amazon picks, packs and ships it, handles the return if there is one, and deposits your proceeds after deducting fees.

The appeal is that you are not running a warehouse. The catch is that you are paying for someone else’s, on their terms, and those terms change.

The four ways sellers source products

Private label means manufacturing a generic product under your own brand. Highest potential margin, highest capital requirement, longest timeline, and the most competitive space because it is the model every course teaches.

Wholesale means buying established branded products from authorised distributors and reselling. Lower margins, faster to start, requires supplier relationships and often brand authorisation.

Retail and online arbitrage means buying discounted stock from retailers and reselling at a markup. Minimal capital to start, does not scale, and involves constant sourcing labour.

Handmade and your own manufacturing for people already producing something.

Most people asking about FBA are considering private label, which is the version requiring the most capital and carrying the most risk.

The fee structure, which is the whole story

This is where most business plans fall apart, because sellers calculate margin on cost versus selling price and forget everything in between.

What comes out of each sale:

• Referral fee — a percentage of the sale price, varying by category
• Fulfilment fee — per unit, based on size and weight
• Monthly storage fees — by volume, and higher in the final quarter of the year
• Long-term storage surcharges on inventory that sits too long
• Return processing, which in some categories you bear entirely
• Advertising, which is effectively mandatory for a new listing to be seen at all

Then, before any of that: manufacturing cost, freight, customs duties, and any inspection or sampling.

Amazon publishes calculators for the fee side, and using one on a real product before committing is the single most valuable hour in this entire process. Fee structures also change periodically, so check current figures rather than relying on any article.

The number that matters is what remains after everything. Sellers routinely discover their apparent thirty percent margin is nearer eight once advertising and returns are counted — and eight percent on a modest volume is not a business.

Choosing a product

This decision determines the outcome more than execution does. What experienced sellers look for:

• Demand that is steady rather than seasonal, unless you specifically want seasonal
• Competition that is beatable — if the first page is dominated by established brands with thousands of reviews each, you are buying a fight
• Small and light, because fulfilment fees scale with size and freight costs scale with volume
• A price point with room — very cheap products cannot absorb the fee structure, and very expensive ones require capital and carry return risk
• Not fragile, not perishable, not requiring certification unless you understand the compliance involved
• Room to be genuinely better than what exists — read the one and two star reviews of the current leaders, because that is where the opportunity is described in the customers’ own words

What to avoid: anything with active intellectual property, anything in a restricted category you are not approved for, electronics with safety requirements you have not researched, and any product where the top sellers are all the same generic item with different logos.

Capital required

Private label realistically needs enough for samples from several suppliers, an initial inventory order, freight and duties, photography and listing creation, and an advertising budget for the launch period — plus reserve for a reorder before the first batch sells out.

That total is meaningfully higher than most promotional content suggests. Starting undercapitalised is the most common failure: the product sells, you cannot afford to reorder in time, you go out of stock, your ranking collapses, and you restart from nothing.

The listing is the product

On Amazon, customers cannot handle the item. The listing is the entire experience.

What matters: professional photography with a clean main image and lifestyle shots showing use and scale, a title containing the terms people actually search, bullet points addressing benefits and objections rather than listing specifications, and backend search terms filled properly.

Reviews drive everything downstream, and manipulating them — buying them, incentivising them, or arranging exchanges — is against policy and a common route to account suspension. Use the legitimate programmes Amazon provides.

The risks worth understanding before starting

Account suspension. Amazon can suspend a seller account, and the process for reinstatement is opaque and slow. Your entire business can stop with no notice and no support line that helps.

Platform dependency. Amazon owns the customer relationship. You do not get an email list. If your ranking drops, your revenue drops the same day.

Fee changes. Structures have been revised repeatedly, and a change of a few percentage points can erase the margin of a business built on thin ones.

Competitors copying you. A successful private label product attracts near-identical listings within months, frequently at lower prices.

Inventory risk. Unsold stock is money in a warehouse accruing storage fees.

Selling from outside the marketplace country

Sellers frequently operate in a marketplace they do not live in. This is normal and workable, but it involves real complexity: tax registration requirements in the destination country, VAT obligations that vary by market, an importer of record for customs, and banking arrangements to receive payouts across borders.

These are not details to improvise. Get advice specific to your country of residence and your target marketplace before you ship anything, because unwinding a mistake here is far more expensive than preventing it.

Who this suits

People with capital they can afford to lose, patience for a timeline measured in quarters rather than weeks, comfort with spreadsheets and margin analysis, and a genuine reason their product is better than what already exists.

It suits poorly anyone hoping for quick returns on minimal investment. That version of FBA was marketed heavily and it is not what the model is.
