Salesupply connects Shopify and Shopify Plus stores to a fulfillment network across Europe and the US through one integration. Orders sync automatically from your store, inventory is positioned close to your customers, and every order is picked, packed and shipped with local carriers while tracking and stock levels sync back to Shopify. Fulfillment, returns and customer care run through one accountable partner.
At a certain order volume, one warehouse can no longer serve every market at the delivery speed customers expect, and every additional country adds carriers, returns flows and stock decisions. Salesupply's Shopify fulfillment services exist for exactly that stage: brands that need multi-market operations without juggling multi-vendor relationships or building them in-house.
Salesupply's ecommerce fulfillment services run on a network of 82 fulfillment centers across Europe and the US, connected to your Shopify store through a single order management system (OMS). Each fulfillment center works with local delivery heroes, while the OMS gives you one connection, one stock overview and one operational picture across all of them.
That architecture is what makes fulfillment for Shopify scale across borders. Adding a market does not mean a new integration project, a new provider or a new contract. It means allocating stock to another location in the same network.
Shopify order fulfillment covers everything between the customer clicking buy and the parcel arriving, plus the return flow after it. Outsourced through Salesupply, the process runs in four automated steps.
The moment an order is placed in your Shopify store, it is transmitted to the Salesupply OMS through the Shopify fulfillment integration. No exports, no manual order entry, no batch uploads at the end of the day. Order data arrives at the fulfillment center that will ship it, in real time, with the routing logic already applied.
Stock is held in the fulfillment centers nearest your demand. A brand selling in the DACH region, the Benelux and the US does not ship everything from one central warehouse; it holds inventory in the fulfillment centers that serve those markets locally. That is what turns three-to-eight-day cross-border delivery into one-to-two-day local delivery, and it is the single biggest lever on both shipping cost and conversion. Stock levels across every location are visible in one view.
Orders are picked and packed in the local fulfillment center and handed to the local carriers that your customers prefer and expect in that specific market. Carrier preference is local: what wins the buy box in the Netherlands is not what customers expect in Italy or the US. Standard packaging, branded packaging and specific packing instructions are all configurable per brand.
Once an order ships, the tracking number and fulfillment status write back to Shopify automatically, which triggers your customer notifications. Inventory movements sync the same way, so available-to-sell in Shopify reflects reality across every warehouse. Your team monitors the whole operation through the Salesupply dashboard, with real-time visibility and reporting.
Brands rarely outsource Shopify fulfillment because packing boxes is hard. They outsource because of what happens around the packing at scale:
Outsourcing to a fulfillment partner converts all of that into one integration and one relationship. Salesupply also runs the adjacent flows that determine post-purchase experience: international ecommerce returns and ecommerce customer service outsourcing, so the customer-facing side of fulfillment does not fragment across providers.
On paper, this is a comparison between two fulfillment providers. In practice, it is a comparison between a referral layer and an operator. Shopify Fulfillment Network matches merchants with external logistics providers in North America and the UK; Shopify itself has not operated fulfillment since 2023. Salesupply operates a network of partner fulfillment centers across Europe and the US through one OMS. One refers your fulfillment out. The other manages it end to end.
Shopify Fulfillment Network is an app in the Shopify App Store that refers merchants to external logistics providers, with Flexport as the preferred partner. Shopify exited fulfillment itself in 2023, selling its logistics operation, including Deliverr, to Flexport. So a merchant who selects SFN is in practice selecting one of its partner 3PLs; Shopify does not store, pick or ship anything. Flexport's warehouses are in the US, Canada and, since September 2026, the United Kingdom. It has none in the EU yet and plans to expand into continental Europe in 2027.
The gate is narrow: sales limited to the US, Canada or the UK, fulfillment managed entirely inside the Shopify admin, and volumes comfortably above the network's commercial floor, since Flexport applies a minimum monthly fulfillment spend of USD 5,000 as of January 2026. Merchants who tick all three boxes can be served through the network. Most scaling brands do not.
The question a scaling brand is really asking is not which app to install, but who will run its fulfillment and who is accountable when a market underperforms. Salesupply's answer is direct: we run the network as one operation, across Europe and the US, and one partner owns the result in every market. In practice that means:
For brands that want a partner coordinating fulfillment, technology and local market operations as one structure, this is the 4PL fulfillment partner model in practice.
International Shopify fulfillment means meeting local delivery expectations in every market you sell in: the right carriers, local delivery speeds, local return addresses and duty-aware shipping flows. Salesupply supports Shopify brands across Europe, the UK and the US from its own network of 82 international fulfillment centers, so expansion into a new market reuses the operation you already run rather than starting a new one.
Brands that also sell across borders weigh two models market by market: cross-border fulfillment from one central stock, or local stock in each country.
The Shopify fulfillment integration connects your store to the Salesupply OMS and handles the full operational data flow: order sync, inventory sync across all warehouses, fulfillment status and tracking writeback, and the returns flow. It is a production-proven connection, not a custom development project on your side.
For Shopify Plus merchants the integration solves a specific pain: multiple stores, one warehouse connection. Multi-channel order routing across Shopify, marketplaces and other platforms runs through the same OMS and its ecommerce integrations; brands selling across several channels can extend this into omnichannel fulfillment.
Standard pick, pack and ship is table stakes. The requirements that differentiate a brand's delivery experience sit on top of it, and they are where many providers say no or charge unpredictably. Salesupply supports custom Shopify fulfillment as standard operational scope:
This is the operational scope COOs and Operations Directors typically arrive with, and it is where Salesupply's model is built to say yes.
Most scaling Shopify brands also sell on Amazon, and running two disconnected fulfillment operations for the same catalogue creates the stock allocation problem every operations team knows. Through Salesupply, Shopify and Amazon orders route through the same OMS and ship from the same stock pool, so inventory is not split and double-safety-stocked per channel.
In the US, Salesupply is accredited for Fulfillment by Merchant (FbM) for Amazon Prime: with delivery across mainland USA in one to two days at local rates, Amazon orders can qualify for Prime while you keep full control over stock, packaging and the fulfillment process, without sending inventory into FBA.
