How It Works

(for BigCommerce Integration)

Step 1

Connect BigCommerce

Connect your BigCommerce store to our WMS, map your locations to our warehouses, and sync orders, stock, and tracking so we can validate your flows with test orders before go-live.

Step 2

Configure rules

Define your rules once—then let our WMS execute them: shipping priorities, carrier logic by country, cut-offs, packaging rules, bundles, inserts, and special tags for VIP or fragile SKUs.

Step 3

Inbound & SKU prep

Send products by pallet, truck, parcel, or container. We receive and check goods, scan and verify SKUs, relabel if needed, and build kits/bundles so inventory is shelf-ready.

Step 4

Storage & visibility

We slot inventory based on product profile and velocity and give you real-time visibility by warehouse: available-to-sell stock, low-stock alerts, and movement history for every SKU.

Step 5

Pick, Pack, Ship & tracking

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

Step 6

Returns & reverse logistics

We manage returns across the EU and the UK: receive, inspect, grade, restock sellable units, and consolidate remaining goods back to you or your suppliers—with reporting your support team can use.

BigCommerce is a cloud e-commerce platform used by brands and retailers to run online stores, manage catalog and pricing, and support different selling models—often including B2C and B2B. With a connected 3PL, BigCommerce merchants can scale order volume while keeping inventory accuracy and delivery promises stable.

Its Open SaaS architecture provides a unique balance of enterprise-grade flexibility and the speed of a managed cloud service. Using Multi-Storefront (MSF) capabilities, brands can launch and manage unique localized experiences across multiple regions from a single, unified control panel. Finally, its API-first design makes it a top choice for headless commerce, allowing developers to build custom front-ends that integrate seamlessly with advanced third-party business systems.

FAQ:

(for BigCommerce Integration)

How fast is the integration?

In most cases we can complete the technical integration within one working day once we have BigCommerce API/admin access and your locations mapped. We then process test orders before go-live to make sure everything works as expected.

Do you support BigCommerce multi-storefront?

Yes. Our WMS can work with multi-storefront setups and separate channels or regions while still using a shared inventory pool, routing orders to the most suitable warehouse.

Can you split inventory across EU + UK warehouses?

Yes. We can position stock in Germany, France, Poland, and the UK and route orders based on availability, destination, and service level.

Can you work with multiple BigCommerce stores or brands?

Yes. We can integrate with multiple BigCommerce stores and manage them under a single 3PL setup, while keeping reporting and stock visibility separated by brand, store or channel as needed.
