Cross-Border Ecommerce Fulfillment
Across Europe and the US

As order volumes grow across multiple markets, a single-warehouse setup starts to break down. Delivery times become less competitive. Shipping costs increase. Customs issues create friction on every parcel. Returns take longer to process. And your operations team ends up managing exceptions instead of scaling the business.

Salesupply answers this with one distributed fulfillment network across Europe and the US. Your inventory is placed closer to your customers, orders ship from local fulfillment centers, and your team manages the full operation with one partner, one integration and one point of contact.

Cross-border is our specialisation, built on the same foundation as our full ecommerce fulfillment services and the wider ecommerce logistics chain: storage, pick and pack, shipping and returns through one connected setup.

A single warehouse means every order crosses a border. International rates. Customs paperwork per shipment. Up to 5-7 day delivery while local competitors deliver next-day.

Salesupply's distributed fulfillment network removes that. It is ecommerce fulfillment built for cross-border sales: the border is crossed once, in bulk, and every customer order ships domestically.

Salesupply is not a single-warehouse 3PL. We operate as a 4PL fulfillment partner: one operational layer managing a network of local fulfillment centers, carriers and fulfillment partners for you.

For purely domestic fulfillment in one market, a direct 3PL can sometimes be the cheaper option. But once you sell across two or more markets, the value shifts. You replace multiple warehouse partners, carrier setups and dashboards with one managed fulfillment network.

Add the savings of local dispatch, faster delivery and simpler returns, and the 4PL model becomes the more scalable setup for cross-border ecommerce growth.

82 fulfillment centers, with local operations across Europe and the United States. Local inventory in fulfillment centers close to your customers means local delivery speeds in every market you serve.

The era of cheap cross-border parcels is ending, market by market. The US abolished its duty-free threshold in 2025. The EU started charging duty on low-value parcels in July 2026. The UK has confirmed its exemption will follow. Every parcel that crosses a border now carries cost and paperwork that local stock does not. Here is what that means per market.

The US: de minimis is gone, every parcel pays duty

Since August 2025, the $800 duty-free threshold is suspended for all countries. Every D2C parcel shipped into the US now needs a customs entry, HTS classification and duty payment; dozens of postal operators suspended US-bound parcels entirely during the transition. Shipping individual orders from Europe into the US is no longer a viable model at scale. With stock in our US fulfillment centers, your goods enter once as a bulk import and every customer order ships domestically with USPS, FedEx and other preferred local carriers, at domestic speed, with regional stock placement shortening delivery further.

The EU: the €150 exemption is ending now

Since July 2026, low-value parcels entering the EU pay a flat customs duty per item, with full duty assessment following in 2028 when the €150 exemption disappears entirely; several member states have added their own handling fees on top. For non-EU brands, the IOSS-and-parcels model gets more expensive every year. With stock in our EU fulfillment centers, goods enter once in bulk and orders ship domestically with the carriers your customers know: DHL in Germany, PostNL in the Netherlands, Colissimo in France and other preferred local carriers.

The UK: full customs since Brexit, and the £135 relief is going too

EU brands selling into the UK face full customs treatment on every parcel: declarations, duty, per-category compliance. The UK has confirmed its £135 low-value exemption will be eliminated as well. With stock in our UK fulfillment centers, goods enter once under a single bulk declaration and every customer order ships domestically with Royal Mail, Evri and other preferred local carriers.

Shopify, Magento, WooCommerce, PrestaShop, Amazon, bol.com, ERP systems or a custom REST API connection: through our ecommerce integrations you connect once to our OMS, and every location in the network is live.

Every brand selling internationally does cross-border fulfillment; the decision is how. Shipping centrally from one warehouse works at low volume or in a single dominant market. Distributing inventory across local fulfillment centers pays off once a brand has meaningful volume in two or more markets and per-order shipping, duties and returns start eroding margin.

The calculation is simple. Distributed fulfillment adds a management layer, and that layer has to pay for itself. It does when three conditions meet: enough volume per market to justify placing stock there; enough markets that managing separate 3PLs, contracts and carrier setups costs real operational time; and product economics where €0.50 to €1.00 saved per order, faster delivery and locally processed returns move the P&L.

The regulation shift moves this calculation too. With de minimis gone in the US and ending in the EU, every centrally shipped parcel now carries duty and clearance cost that local stock does not. The crossover point sits at lower volumes than it did a year ago.

In practice, a brand doing 1,000+ orders per month with real traction in at least two markets is at the crossover. Below that, stay centralised; the model would cost you more than it saves.

Evaluating a cross-border fulfillment partner comes down to four checks: whether the network is managed as one, how returns physically move in each market, what activating a new market takes, and how performance is measured and reported per location.

You know what a fulfillment partner does. What is harder to see from a sales conversation is where cross-border setups fail after go-live. These are the questions worth asking every provider on your shortlist, including us.

Is the network managed as one?

Many providers run one warehouse and add others through separate arrangements. Ask whether every location connects through one system, whether SLAs apply across the whole network, and who is accountable when a location underperforms.

What physically happens to a return in each market?

Not the portal, the parcel. Where does it go, who registers it, how many days until it is sellable stock again, and in which market does it end up. Cross-border returns are where fulfillment economics break down.

What does adding a market take?

A new contract, a new integration and a three-month project, or an activation on the existing setup? The answer tells you whether you are buying a warehouse or a network.

How is performance measured, and will you show me?

On-time rate per location, order accuracy, returns cycle time, and whether those numbers are SLA-backed or aspirational. A provider confident in its network shows the dashboard before the contract.

Cross-border ecommerce fulfillment is the process of storing, picking, packing and shipping online orders to customers in countries other than where the brand is based. Unlike domestic fulfillment, where orders ship within a single market, cross-border fulfillment involves customs documentation, international shipping rates, VAT registration per market and return logistics across borders.

For ecommerce brands selling in multiple countries, the challenge is delivering a local experience (local delivery speeds, local carrier tracking, no surprise customs charges) without building warehouse infrastructure in every market. A distributed fulfillment network handles this by placing inventory in each target market and shipping orders locally, while managing the entire operation through a single integration.

Cross-border fulfillment is not the same as international shipping. International shipping sends a parcel across a border on every order. Cross-border fulfillment positions stock locally so the border is crossed once, in bulk, and every customer order ships domestically.

This model is also called localized fulfillment: the terms describe the same approach from two angles. Cross-border fulfillment names the problem being solved, selling across borders. Localized fulfillment names the mechanism, fulfilling each order from local stock.
