FLEX. Fulfillment is the operator. This is the guide library for sellers and brands who need to understand how European fulfillment actually works when it connects to a real sales channel — not how it works in theory.
Selling through Shopify, Amazon, OTTO, Allegro, Zalando, TikTok Shop or other channels in Europe is not just a connector problem. It is an operational design problem: inventory sync, dispatch cutoffs, shipping rules, returns logic, warehouse location and country-specific execution all have to work together. Getting any one of them wrong creates visible service failures — late deliveries, rejected inbounds, broken inventory counts, unprocessed returns.
This library covers 18 platforms across three categories: store platforms (Shopify, WooCommerce, Magento, PrestaShop, BigCommerce), Amazon execution modes (FBM, Seller Fulfilled Prime, FBA prep), and European marketplaces (OTTO, Allegro, Kaufland, TikTok Shop, eBay, Cdiscount, Zalando, bol.com, ManoMano, Wayfair). Each guide focuses on the fulfillment reality of that specific channel — what the integration requires, where things break, and how to build a stable operation.
Not Sure Where to Start?
If you're running a single primary store or marketplace, start with the guide for that channel. If you're running a multichannel setup — or planning to expand from one channel to several — start with Shopify Fulfillment in Europe (the most common entry point for DTC brands) or Amazon FBM Fulfillment in Europe (the most common entry point for marketplace-first sellers).

Start here if your business runs primarily through your own ecommerce stack and you need to understand how a European 3PL should connect, sync and execute behind it.

How FLEX. Solves the Hard Parts
Across all channels and platforms, the same operational problems tend to decide whether European fulfillment stays stable or starts breaking: disconnected inventory counts, weak returns logic, warehouse location that doesn't match primary delivery demand, carrier networks that don't cover required countries, and manual patching between systems that should be automated.
FLEX. addresses those problems through one WMS, one operator and a three-warehouse network across Germany, Poland and France. Each spoke guide in this library explains where that infrastructure matters for the specific platform or marketplace — and what a stable, connected European operation looks like in practice.
