Amazon basics for brand owners
Fulfilment by Amazon is a warehousing and shipping service. You send your stock into Amazon's network in bulk, Amazon stores it, and when a customer orders, Amazon picks it, packs it, ships it and handles the return if one comes back. You pay a fee per unit shipped and rent for the space the stock occupies.
The reason almost every serious Amazon brand uses it is not the logistics. It is the Prime badge. An item fulfilled by Amazon is Prime eligible, and for anything a shopper compares against a Prime alternative, that badge is the difference between being considered and being skipped.
How the process actually runs
The sequence is the same for every product. You create a listing and mark it as fulfilled by Amazon. You create a shipment plan in Seller Central, which tells you how many units to send and to which warehouses — often more than one, which surprises people the first time. You label each unit with the code Amazon assigns, box them to the packing rules, label the boxes, and ship them in.
Amazon receives the stock, checks it in over some days, and the listing becomes available with the Prime badge. From there the daily operation is out of your hands. Orders are picked and shipped, customer service on delivery issues is handled by Amazon, and returns go back into the network to be assessed as sellable or not.
What remains yours is everything upstream. Manufacturing, quality, how much stock to send and when, the listing content, the price, and the advertising. Fulfilment by Amazon is a warehouse and a courier, not a business partner.
Two operational details that catch new brands. Preparation requirements are strict: liquids need sealing, sets need bagging with a suffocation warning, fragile items need protection that survives being dropped by a conveyor. And the stock is not tied to you once it arrives — if the same item is stored from multiple sellers, Amazon may ship any of them to your customer unless you use the stickered option, which for a brand worried about counterfeits is worth choosing.
What it costs
Two main charges and several smaller ones.
The fulfilment fee is per unit and is driven mostly by packed dimensions, then weight. A dense small item is cheap to fulfil. A bulky light one — a cushion, a large frame, a basket — costs far more than its price suggests, because the network charges for space. Check your packed dimensions against the size bands before you commit, since falling just over a threshold can add several dollars a unit.
Storage is charged monthly by the volume your stock occupies, and it rises in the last quarter of the year when space is scarce. Stock that sits past a long-term threshold picks up a surcharge on top. Amazon FBA storage fees covers the bands.
Then the smaller ones, which add up. Charges around how you send stock in and how thin your cover runs, removal or disposal fees for getting unsold stock back out, and returns processing in some categories. The low-inventory charge is one of the more recent additions.
A worked example on a $29 standard-size product. Referral fee at fifteen percent is $4.35. Fulfilment lands near $5.50. Storage across the months it sits adds perhaps $0.40. Cost of goods $7. That leaves about $11.75 before advertising, which in a competitive category might take another $4 or $5. The full stack is in Amazon seller fees.
Where it genuinely helps
Three things, and they are bigger than they look on a spreadsheet.
Conversion. The Prime badge and a two-day promise beat a merchant-fulfilled listing offering five days, consistently, on identical products at identical prices. In categories where shoppers compare, this alone justifies the fee.
Time. A brand owner's scarcest resource is attention, and packing parcels is the lowest-value use of it. A maker who stops packing and starts making, or a founder who stops shipping and starts building a second channel, gets more from that hour than the fulfilment fee costs.
Scale without flinching. A listing that suddenly sells three hundred units in a week is a good day rather than a crisis. Handling that yourself means a very bad week.
Where it hurts
Four places, and all four are predictable.
Bulky and light products are punished by a fee structure built around space. If your product is large relative to its price, run the arithmetic before assuming fulfilment by Amazon is right.
Slow sellers are punished by storage. A wide catalogue of low-volume variations costs rent every month on the ones nobody buys, and the long-term surcharge arrives on exactly the stock you were hoping would move.
Cash is locked in inventory sitting in someone else's building, and getting it back out costs removal fees plus the time to find somewhere to put it.
And the stock is not available for anything else. This is the one that matters most for a brand thinking beyond the marketplace: units in Amazon's network cannot easily be shipped to a shop, put in a trade show booth, or used to fill a wholesale order. They are committed to one channel.
Using FBA stock for orders that are not Amazon orders
There is a partial answer to that last problem, and most brand owners do not know it exists.
Multi-channel fulfilment lets you send an order to Amazon that did not come from Amazon. You supply the address, Amazon ships from your stock, and you pay a fee that is higher than the standard fulfilment fee. Brands use it to fulfil their own website orders without running a second warehouse.
It can serve small wholesale orders too, with caveats. The parcel may arrive in Amazon-branded packaging unless you use the unbranded option, the cost per unit is high for a case of twelve going to one address, and it is built around parcels rather than pallets. For a shop ordering six candles it works. For a distributor ordering four hundred units on a pallet it does not. Amazon multi-channel fulfillment for wholesale covers where the line falls.
The other route is a removal order: you ask Amazon to send stock back to you or to an address you name, then ship it onward yourself. It is slow and the per-unit fee is small, which makes it a planning tool rather than a fulfilment method. Amazon FBA removal orders wholesale covers how brands use it when a retail order lands and the stock is in the wrong place.
When a brand outgrows it
The pattern is consistent. A brand runs fulfilment by Amazon happily while Amazon is the only channel. Then a second channel appears — a website doing real volume, a few shops reordering, a distributor asking about pallets — and the single-channel warehouse becomes a constraint.
At that point a third-party logistics provider starts to make sense. One warehouse holds all your stock, ships parcels for your own site, ships cases to shops, ships pallets to distributors, and sends replenishment shipments into Amazon as needed. You pay more per parcel than Amazon charges and you gain the ability to serve every channel from one pool of inventory. 3PL vs FBA covers the comparison, and Amazon FBA alternatives covers the full set of options including the hybrid most brands land on.
Most brands do not choose. They keep fast-moving lines in fulfilment by Amazon for the Prime badge and hold the wholesale inventory somewhere they control, splitting stock between the two. That split is a planning problem rather than a philosophical one, and it gets easier once you know roughly what each channel sells in a month.
The question underneath all of this
Fulfilment by Amazon is very good at one thing: delivering single units to individual consumers who found you through search. Every cost in it is built around that job.
Wholesale is the opposite job — many units to one business address, on a purchase order, at half of retail, with no advertising cost and no customer service attached. The fee structure that makes single-unit fulfilment expensive largely disappears, and the customer reorders without you doing anything to win them again.
That is why the fulfilment question and the channel question are the same question. To see whether a second channel is realistic for your product, paste a link into WholesalePilot and the preview shows which distributors and retailers plausibly stock something like it.
Questions brand owners ask about FBA
Do you have to use FBA to sell on Amazon? No. You can fulfil orders yourself, and many brands do for large or customised items. The Prime badge is the trade-off.
Can some products be FBA and others not? Yes, per listing. Splitting by product size and turn rate is normal and usually optimal.
Who handles customer service on FBA orders? Amazon handles delivery and returns questions. Product questions still come to you.
Is stock in FBA insured? Amazon compensates for units lost or damaged in its network under its policies, but reconciliation is on you to check. Review inventory reports rather than assuming.
