FC (Fulfilment Centre)

Amazon & D2C glossary · Harpy Media

An FC (Fulfilment Centre) is an Amazon-operated logistics facility: a warehouse engineered around receiving, storing, picking, packing, and shipping inventory at internet scale. Thousands of them, in networks by region, with robots, conveyor systems, and process rigidity that makes a parcel look easy.

What is FC?

For sellers, the FC is where two relationships meet: your inventory’s physical reality (dimensions, prep, packaging, age) and your account’s economics (fees, capacity, availability). The FC doesn’t negotiate, doesn’t flex for your exceptions, and prices everything it touches — which is why the sellers who understand how it works pay it less.

What happens to your inventory inside

The journey: receiving (your shipment’s data and reality either match — or generate fees and delays), stowing (into space measured by cubic feet), storage (metered monthly, aged by the calendar), picking and packing (optimised for standard units and machine-readable handling), shipping (network routing to hit delivery promises), and the reverse lane (returns graded and dispositioned). Every standard the FC enforces — labels, prep, dimensions, appointment discipline — exists because the machine can’t slow down. And the machine’s incentives become policy: fast-turning, compact, compliant inventory is cheap to run; slow, bulky, awkward inventory pays for the space it slows down.

Working with FCs instead of against them

Practical levers: inbound compliance (labels, ASNs, appointments — clean loads receive fast and cheap), placement realities (splitting inventory across FCs improves promises; consolidation saves inbound cost — a trade-off to manage, not a preference), capacity planning (peak-season limits reward sellers whose inventory performs — sales per cubic foot again), and disposition strategy for returns (graded resellable stock re-enters; the rest chooses removal or disposal on the fee schedule). The mental model that saves the most money: the FC is a metered utility. Every inch, every day, every exception is on the meter — design the product and the flow for the meter.

In practice

A seller’s inbound shipments average nine days from arrival to sellable — versus a five-day benchmark — because labels fail first-touch scans on one carton pattern. Fixing the label placement and standardising cartons brings receiving to four days. Nine to four days is five days of earlier sales on every shipment, all year — a rank-and-velocity gain that never shows up as a ‘fee’ but compounds like one.

⚠️ Watch out. A seller treats the FC like a warehouse where “close enough” is fine — labels a little off, cartons a little non-standard, appointments approximate. Every exception becomes fee lines and dwell time, and the seller’s mental model (“Amazon lost my stuff”) never updates to the actual cause (nothing passed first touch).

💡 Harpy tip. Track your own “arrival to sellable” days per shipment for a quarter. It’s the invisible KPI of FC relationships — and shrinking it is pure velocity for free.

How Harpy Media helps

Inbound-to-sellable speed is a metric we watch on every FBA account — the FC’s first touch is where weeks of sales are quietly won or lost.

FC FAQ

What is a fulfilment centre?

An Amazon-operated logistics facility that receives, stores, picks, packs, and ships seller/vendor inventory at scale.

Can sellers choose their FC?

Placement is largely Amazon’s decision based on inventory distribution — though inbound options and splits influence it, with cost trade-offs.

Why do FC standards matter so much?

Because non-compliance generates fees, receiving delays, and lost sales velocity — the machine only moves at full speed when your input is first-touch perfect.
