to connect a new e-commerce customer

The problem

IT integration has become the 3PL's bottleneck

Three months to connect a customer, really?

A customer go-live drags on for weeks because of EDI specifications, back-and-forth with WMS vendors, manual testing. Customers lose patience, and sometimes walk away.

IT consultancies charge top dollar for every connector

Every new CMS, every new ERP is a quote, a project, a dependency. Integration costs eat into your margin on new contracts, especially on mid-market e-commerce accounts.

Every API update breaks a flow

Shopify, Magento, Amazon and SAP change their APIs without warning. Flows break, IT teams firefight. Maintenance consumes the time that should go into building the 3PL's own platform.

Digital 3PLs are hoovering up the tenders

BigBlue, Hive, Everstox, Huboo, ShipBob, ShipMonk, Stord sell a standard digital experience to e-commerce brands. A traditional 3PL that can't promise fast onboarding loses before the demo even starts.

The solution

One integration hub, three modules

The Spacefill API

An open, documented REST API. The 3PL's customers who have a tech team can integrate on their own, without waiting for the 3PL to build a custom connector.

  • Endpoints for stock, orders, statuses and returns
  • Real-time webhooks
  • Developer portal and sandbox
  • OAuth2 authentication

Native e-commerce connectors

The most widely used CMS platforms and marketplaces are pre-integrated. The 3PL activates the connector for a customer in a few clicks, and order and stock flows feed the WMS automatically.

  • Shopify, PrestaShop, Magento, WooCommerce, Odoo
  • Amazon, Cdiscount, Mirakl
  • No-code configurable field mapping
  • Error handling and flow replay

Custom ERP integrations

For customers with a custom ERP or structured EDI flows, Spacefill combines existing connectors with EDI integrations built by its project teams. Up and running in 15 days.

  • SAP S/4HANA, Sage X3, Oracle, Axelor, Odoo
  • EDI X12, EDIFACT, custom formats
  • End-to-end testing run by Spacefill
  • Flow configuration per customer
  • Roughly 3x faster to set up than an IT consultancy
Architecture

Where Spacefill fits into the 3PL's IT landscape

  • Open REST API
  • CMS & marketplace connectors
  • EDI & ERP (X12, EDIFACT, custom)
  • Rules engine & mapping
  • Flow monitoring and replay
  • Maintenance included

How it works

From onboarding to go-live

Step 1

Express scoping

Identifying which systems to connect on the customer side and on the 3PL's WMS side. Choosing the modules: API, CMS hub or EDI.

Step 2

No-code configuration

Mapping customer fields to the WMS in the Spacefill interface. Transformation rules, filters, edge cases.

Step 3

End-to-end testing

Automated test suite on the customer's real scenarios: order, cancellation, return, stock sync.

Step 4

Go-live and run

Switch to production, monitored by the Spacefill team. API updates are handled on an ongoing basis.

Before / After

Onboarding a new e-commerce customer

Standard scenario: a 3PL signs a contract with a Shopify brand that also sells on Amazon. Go-live on the WMS side.

Internal IT scoping + EDI

Internal IT scoping, writing EDI specifications, back-and-forth with the WMS vendor to open the flows.

Scoping + connector activation

Scoping the systems to connect, activating existing connectors. Field mapping configured with no code.

Custom development for every CMS

Custom development for each new CMS or marketplace. Manual testing, test data rebuilt by hand.

Automated testing

Automated tests on the customer's real scenarios. No custom development, CMS and marketplace connectors are pre-built.

Go-live in 6 to 12 weeks

Live 6 to 12 weeks later. IT team permanently tied up on maintenance.

Go-live in days

Live in a few days. Maintenance handled by Spacefill. IT team freed up for the product roadmap.

Customer story

Prévoté Logistique centralizes its flows and cuts administrative costs

Prévoté Logistique handled its e-commerce customers' integrations case by case, with a fresh IT project for every new contract. Internal teams spent too much time setting up and maintaining connectors, at the expense of commercial expansion.

Management was looking for an integration platform that could speed up customer onboarding and standardize flows with their WMS, while offering a customer collaboration portal under their own brand.

ERP & EDI

Connecting a customer's ERP almost becomes a pleasure

For simple integrations, the library of existing ERP connectors is often enough. For complex cases, Spacefill teams and their partner handle the custom EDI integration, with a guaranteed start within 15 days.

The 3PL validates the functional scope. Spacefill runs the configuration, the testing and the go-live. No internal development, no dependency on an IT consultancy.

Frequently asked questions about 3PL Connect

Spacefill 3PL Connect is an integration platform for logistics providers. It connects the systems of the 3PL's customers (e-commerce CMS, marketplaces, ERP, TMS) directly to its WMS, with no custom development. 50+ WMS are natively pre-integrated. Onboarding a new e-commerce customer takes a few days, against several weeks with classic EDI.

Spacefill is pre-integrated with more than 50 WMS, including all the leaders on the French and European market: Reflex (Hardis), Infolog (Generix), Speed, Odatio (Savoye), StockIt (Sinari), Effitrace, Bext, Mecalux, EPG, Akanea. The platform can also be integrated with custom or proprietary WMS.

For a customer on a standard CMS (Shopify, PrestaShop, Magento, WooCommerce) with a WMS already integrated with Spacefill, onboarding takes a few days. For a custom EDI integration with a complex ERP, Spacefill commits to starting the project within 15 days, for a setup roughly 3 times faster than with an IT consultancy.

Spacefill handles connector maintenance and flow error management. API updates on the CMS, marketplace or WMS side are taken care of by Spacefill teams. The 3PL doesn't have to tie up its IT resources on the run phase.

No. Spacefill 3PL Connect is an integration layer that plugs into the 3PL's existing WMS. It doesn't replace any system. It acts as a bridge between the WMS and the systems of the 3PL's customers (CMS, marketplaces, ERP, TMS, carriers).

CMS: Shopify, PrestaShop, Magento, WooCommerce, Odoo. Marketplaces: Amazon, Cdiscount, Mirakl. ERP: SAP S/4HANA, Sage X3, Oracle, Odoo, Axelor. Transport: GedMouv, Akanea, Sendcloud, ITinsell, Teliae, plus 50+ sales channels.

3PL Connect adds no value for 3PLs handling only structured EDI flows between large accounts, with no e-commerce or marketplaces in their customer base. The tool is built for 3PLs whose customer base includes e-commerce or omnichannel brands with a variety of systems to connect.

3PL Connect is an integration platform, not a WMS or a shipper-side OMS. It doesn't handle physical warehouse operations, nor multi-3PL order orchestration on the shipper side (that scope is covered by other Spacefill products). Some highly custom ERP connectors may require a dedicated EDI project rather than a native plug-in.
