The usual answer is that a warehouse stores goods and a fulfilment centre moves them. That is true, and for most guides it is where the explanation stops. In Europe there is a third difference that matters more than either, and almost nobody writes about it: where the building sits relative to the EU customs union changes what every order costs. The standard distinction, briefly A warehouse is built around space. Stock arrives on pallets, sits for weeks or months, and leaves in bulk to retailers or distribution hubs. Outbound volume is low, predictable and scheduled. A fulfilment centre is built around movement. Stock arrives, individual orders are picked continuously, parcels go to consumers, and returns come back. Outbound volume is high, unpredictable and constant.

Stock held inside the EU customs union is in free circulation. Orders to any EU member state are domestic movements — no customs entry, no clearance, no duty. Stock held outside it is not, and every order entering the EU carries a customs declaration regardless of how fast the building picks it. That is why a fast warehouse in the wrong place loses to a slower one in the right place. A brand comparing two providers on pick speed, while one sits outside the customs union, is optimising the smaller variable. A related term worth knowing: bonded warehousing holds imported goods with duty and import VAT suspended until they leave. It suits stock being re-exported or held in bulk before a decision. It is not the same as free circulation, and for direct-to-consumer ecommerce inside the EU, free circulation is usually what you want. Why the question is usually framed wrong Most guides present this as a choice. For a growing brand it rarely is. A brand selling direct to consumers and to retailers needs both. Pallets going to a stockist and parcels going to a customer are different operations, but they draw on the same inventory. Splitting them across two providers means two stock pools, two sets of records, two reconciliations, and a permanent question about which pool a unit belongs to. The better question is not warehousing or fulfilment. It is whether one operation can do both from one stock pool. At efulfilment.eu, bulk storage and pallet distribution to retailers run alongside direct-to-consumer orders from the same inventory, in Almere in the Netherlands — inside the EU customs union, with access to 75+ carrier options. What to ask, depending on where you are Three situations, three different questions. You are holding stock and shipping it yourself You have a storage problem that is becoming an operations problem. Ask what the dispatch cut-off is, whether stock sync with your webshop is real time or a nightly batch, and how returns are handled. Those three decide whether moving solves anything. You sell to retailers and to consumers Ask whether both run from one stock pool or two. If the answer is two, ask who reconciles them and how often. This is the question that separates a warehouse offering fulfilment from a fulfilment operation that also does bulk. You are importing into Europe Ask where the stock will physically sit and whether it will be in free circulation. Then ask what happens to a return from Germany. Everything else is secondary to those two answers. When a warehouse is genuinely the right answer Not every brand needs fulfilment. A warehouse is the better fit when stock moves in bulk, orders are scheduled rather than continuous, returns are rare, and speed to the end customer is not the constraint. Wholesalers, manufacturers and brands whose growth is through retail distribution are usually better served by storage and scheduled outbound than by a parcel operation. The mistake is not choosing a warehouse. It is choosing one, then adding direct-to-consumer volume on top and expecting the same building to absorb it. Frequently asked questions What is the difference between a warehouse and a fulfilment centre? A warehouse is built around storage — stock arrives in bulk, sits, and leaves on pallets to businesses. A fulfilment centre is built around throughput — individual orders are picked continuously, parcels go to consumers, and returns are processed routinely. One is priced on space occupied, the other on orders processed. Can a warehouse handle ecommerce orders? Some can, but most are not set up for it. High order frequency, individual picking, live integration with a webshop and routine returns handling are operational capabilities rather than floor space. A warehouse without them can store your stock but will struggle to dispatch it at ecommerce pace. Do I need warehousing or fulfilment? Often both. Brands selling to retailers and to consumers need bulk storage and parcel dispatch from the same inventory. The useful question is whether one provider can do both from a single stock pool, rather than which of the two to pick. What is bonded warehousing? Bonded warehousing holds imported goods with customs duty and import VAT suspended until they leave the facility. It suits stock being re-exported or held in bulk before a destination is decided. For direct-to-consumer selling inside the EU, stock in free circulation is usually the better position. Does it matter where in Europe my stock is held? Yes, more than most comparisons allow for. Stock inside the EU customs union ships to member states as a domestic movement with no customs entry. Stock held outside it carries a customs declaration on every order into the EU, regardless of how quickly the warehouse picks.
