How It Works

(for Amazon Integration)

Step 1

Connect Amazon

Authorize our integration with your Amazon Seller Central account, map marketplaces and stock locations to our warehouses, and sync FBM orders, inventory, and returns in real time for quick testing.

Step 2

Configure shipping templates & rules

Define shipping templates and handling rules once—then let our WMS apply carrier choices per country, route standard and priority flows, and enforce your service levels automatically.

Step 3

Inbound & SKU prep

Send cartons, pallets, or containers. We receive and check goods, verify barcodes, relabel SKUs if needed, perform prep work where required, and make stock shelf-ready for fast FBM picking.

Step 4

Storage & visibility

We place each SKU in the right storage location and give you real-time visibility on Amazon-ready stock by site, low-stock alerts, and history—so you can reduce cancellations and protect performance metrics.

Step 5

Pick, Pack, Ship & tracking

We pick and pack to your SOPs, use agreed packaging and inserts, follow Amazon shipping templates, ship within promised handling times, and send tracking updates back to Amazon automatically.

Step 6

Returns & reverse logistics

We handle Amazon returns across the EU and the UK by receiving parcels, checking and grading items, restocking what can be resold, quarantining problem stock, and consolidating remaining goods back to you.

Amazon is a global e-commerce marketplace where brands and resellers list products, manage offers, and reach customers through country-specific storefronts. Sellers use Seller Central for catalog, pricing, inventory, and order management, choosing between FBM (Fulfilled by Merchant) and FBA (Fulfillment by Amazon)—with strict standards around delivery speed, tracking quality, and customer experience.

To succeed in this competitive environment, merchants often leverage internal advertising tools like Sponsored Products to increase their visibility within search results. Constant monitoring of the "Buy Box" is also essential, as competitive pricing and high seller ratings directly influence conversion rates. Ultimately, the platform provides an unparalleled logistics infrastructure that allows even the smallest brands to achieve global reach with relative ease.

**Services for Amazon Merchants**

B2C fulfillment in Europe and the UK

Fast fulfillment built for Amazon expectations: reliable last-mile options, scalable operations, and workflows that reduce late deliveries and support tickets.

Value-Added 3PL Services

Beyond core fulfillment, FLEX. can relabel, polybag, bundle and kit products, add marketing inserts or gift notes, and run QC or rework projects before goods move through your channels.

Amazon FBM & SFP support (where applicable)

Use FLEX. to fulfill Amazon FBM and, where eligible, SFP orders from one inventory pool—keeping account-health metrics stable while we manage pick, pack, shipping, and returns.

Pre-Amazon Storage & FBA Prep

Run a hybrid setup: store and prep inventory locally, forward to Amazon fulfillment centers when needed, and still use the same inbound stock to support FBM and other channels.

FAQ:

(for Amazon Integration)

How fast is the integration?

In most cases we can complete the technical integration within one working day once we have Seller Central access and your SKUs and marketplaces mapped. We then process test orders before go-live.

Do you support multiple Amazon marketplaces (EU + UK)?

Yes. We can connect multiple marketplaces under one account and route FBM orders to the most suitable warehouse based on country, service level, and available stock.

Will tracking be sent back to Amazon automatically?

Yes. Once an order ships, we confirm dispatch and upload the tracking number through the integration, helping you maintain valid tracking rate and on-time delivery metrics.

Can you work with FBA and FBM together?

Yes. Many clients use FLEX for pre-Amazon storage and FBA prep while also fulfilling FBM orders from the same inventory. This hybrid setup gives more control over costs, resilience and slow-moving or oversized SKUs.
