One source of truth
for orders, inventory,
and customers.

Your commerce platform, ERP, warehouse, 3PL, and marketplaces - all connected and in sync. We build the integration layer that makes multi-channel commerce operationally manageable rather than a full-time fire-fighting exercise.

The integration layer that
makes multi-channel work.

Order Management System (OMS)

A single system where every order from every channel lands - website, app, Amazon, eBay, in-store - with unified routing rules that send orders to the right warehouse or 3PL based on stock location, shipping cost, and delivery promise.

Multi-channel ordersSmart routingReturns management

Inventory synchronisation

Real-time inventory levels pushed to every channel simultaneously - preventing overselling on Amazon while underselling on your own site. Buffer stock rules, safety stock thresholds, and automatic channel de-listing when stock hits zero.

ERP integration

Two-way integration with SAP, Oracle NetSuite, Microsoft Dynamics, and Sage - order data flowing into the ERP for financials, stock updates flowing out to commerce. Event-driven architecture that handles ERP latency gracefully.

Marketplace integration

Catalogue listing, pricing management, order ingestion, and inventory sync across Amazon Seller Central, eBay, Etsy, ASOS Marketplace, and others. Centralised product content with per-marketplace attribute mapping.

3PL & warehouse integration

Direct integration with your 3PL or WMS - automated despatch messages, ASN processing, pick confirmation, and returns receipting. Eliminates the manual CSV uploads and email workflows that create delays and errors.

AI inventory & demand layer

Demand forecasting models that predict per-SKU, per-channel demand - triggering purchase orders automatically when stock falls below model-recommended levels. Reduces both stockouts and the capital tied up in excess inventory.

Integration architecture that doesn’t break.

Most commerce integration problems aren’t technical - they’re architectural. Direct API calls between systems create brittle point-to-point connections where any system going slow brings everything down.

We build on an event-driven integration backbone - typically Apache Kafka or AWS EventBridge - so each system publishes events and subscribes to what it needs. A slow ERP doesn’t block your checkout. A 3PL outage doesn’t prevent orders from processing.

  • Event-driven architecture - systems are decoupled and independently scalable
  • Dead letter queues - failed events are retried automatically and flagged for review
  • Full integration monitoring - every message tracked, every failure alerted
  • Idempotent processing - duplicate messages don’t create duplicate orders or stock movements
  • Schema versioning - API changes on either side don’t break the integration silently

MULTI-CHANNEL RETAILER

OMS + marketplace integration - website, Amazon, eBay, 3PL, and SAP unified

Built a unified OMS connecting Shopify, Amazon Seller Central, eBay, a UK 3PL, and SAP ERP for a mid-market retailer. Real-time inventory sync across all channels, automated despatch to 3PL, and AI demand forecasting reducing overstock by 28%.

↑ Real-time inventory across 4 channels
↑ Oversells reduced to zero
↑ 28% overstock reduction via demand AI
↑ Manual CSV uploads eliminated entirely

Integration monitoring included: Every integration we build ships with a monitoring dashboard showing message volumes, processing latency, error rates, and queue depth - so you can see when something’s wrong before your customers do.
