Fulfilled by Amazon

FBA

Fulfilled by Amazon (FBA) is a service in which you send your inventory to Amazon's fulfilment centres, and Amazon stores it, then picks, packs, ships and handles customer service and returns for every order. You keep ownership of the stock; Amazon handles the logistics.

Key facts

  • With FBA you ship inventory into Amazon's warehouses and Amazon fulfils each order on your behalf.
  • FBA orders are Prime-eligible, which improves conversion and helps win the Buy Box.
  • You pay storage fees (charged by volume and time) plus per-unit fulfilment fees based on size and weight.
  • Amazon handles customer service and returns for FBA orders, removing most of the day-to-day logistics burden.

How FBA works

Under Fulfilled by Amazon, you send your products in bulk to an Amazon fulfilment centre. Amazon stores them, and when a customer orders, Amazon's staff and systems pick the item, pack it, ship it and provide tracking. Amazon also fields customer-service enquiries and processes returns for those orders.

You still own the inventory and set the price; you are effectively outsourcing the warehousing and delivery. This is what makes FBA orders eligible for Prime, since they ship from Amazon's own network with Amazon's delivery promise. Prime eligibility is a strong driver of conversion and a major factor in winning the Buy Box.

In Europe, Amazon offers programmes such as Pan-European FBA and the European Fulfilment Network that let you store stock in one or more countries and have Amazon fulfil orders across multiple EU marketplaces, which can shorten delivery times and reduce cross-border friction.

FBA fees and trade-offs

FBA charges two main fee types: storage fees, billed by the volume your stock occupies and the length of time it stays (with higher rates for long-term or slow-moving inventory), and fulfilment fees, charged per unit based on the item's size and weight. These are separate from the marketplace referral (commission) fee you pay on every sale.

The trade-off is convenience and reach versus cost and control. FBA removes the logistics workload, unlocks Prime, and improves Buy Box odds, but the fees eat into margin, and slow sellers can rack up long-term storage charges. You also hand over the unboxing experience and have less direct control over how returns are processed.

Many sellers run a hybrid model: high-velocity, Prime-sensitive products go through FBA, while bulky, slow or low-margin items are fulfilled by the merchant. Calculating the landed cost per item under each method is the only reliable way to decide which products belong in FBA.

Example

A seller ships 500 units of a phone case into an Amazon fulfilment centre. When a customer in Germany orders one, Amazon picks, packs and ships it with Prime delivery, handles the tracking, and processes the return if the customer sends it back. The seller pays a per-unit fulfilment fee and monthly storage on the units still in the warehouse.

Why it matters for marketplace sellers

  • FBA makes your offers Prime-eligible, which lifts conversion and strengthens your position when competing for the Buy Box.
  • It removes the warehousing, shipping and returns workload, freeing time to manage listings across more marketplaces.
  • Storage and fulfilment fees reduce margin, so it pays to model the landed cost per item before committing a product to FBA.
  • European FBA programmes can fulfil orders across several EU marketplaces from pooled stock, simplifying multichannel logistics.
