How It Works

(for OTTO Integration)

Step 1

Connect OTTO

Connect your OTTO seller environment to our WMS, map marketplaces and locations to our warehouses, and sync orders, inventory, and returns in real time so we can test and validate flows quickly.

Step 2

Configure rules

Define shipping and handling rules once—then let our WMS route OTTO orders, apply carrier choices by destination country, and enforce your priorities and service levels automatically.

Step 3

Inbound & SKU prep

Send products by container, truck, pallet, or parcel. We receive and check goods, scan and relabel SKUs if needed, and build kits or bundles so stock is shelf-ready for efficient marketplace picking.

Step 4

Storage & visibility

We place each SKU in the right storage location and give you real-time visibility on OTTO-ready stock by site, available-to-sell quantities, low-stock alerts, and movement history for every item.

Step 5

Pick, Pack, Ship & tracking

We pick and pack OTTO orders to your SOPs, use agreed packaging and inserts, follow your carrier rules, ship same-day before cut-off (eligible orders), and push tracking updates back into OTTO automatically.

Step 6

Returns & reverse logistics

We handle returns from Germany, the EU, and the UK by receiving parcels, grading items, restocking what can be resold, and consolidating remaining goods back to you or your suppliers.

OTTO Market is a leading German online marketplace where brands and retailers list products, manage offers, and reach customers primarily in Germany. For many sellers, OTTO is a strategic channel to expand into the DACH region without building local operations from scratch. To maintain high quality standards, the platform operates on a curated model, requiring partners to meet specific sustainability and service criteria before they can begin selling.

This selective approach fosters a premium environment where merchants can benefit from the high brand trust OTTO has established with its loyal consumer base over decades. Furthermore, sellers can utilize integrated marketing services and advanced data insights to tailor their assortments specifically to German shopping preferences and seasonal trends.
