The Business Challenge

A growing retailer was selling through its own store and several marketplaces, with staff manually re-keying orders into the ERP and adjusting stock levels by hand.

Overselling, missed orders and end-of-day reconciliation were consuming hours daily and limiting how many channels the business could realistically operate.

02

Existing Technology Environment

  • E-commerce storefront plus multiple marketplace seller accounts
  • ERP as the operational system of record
  • Spreadsheet-driven stock adjustments and manual order entry

03

Our Approach

  1. 01Mapped every data flow — orders, stock, pricing, product data, dispatch confirmations — and defined the ERP as the single source of truth.
  2. 02Built an integration layer with queues, retries and idempotent processing so a failed message could never become a lost order.
  3. 03Added monitoring and reconciliation reports that surface any discrepancy automatically.
  4. 04Rolled channels onto the platform one at a time to de-risk cutover.

04

The Solution Delivered

  • A central integration platform synchronising orders, stock and product data across all channels in near real time.
  • Automated dispatch and tracking updates back to every marketplace.
  • Alerting and reconciliation dashboards replacing manual end-of-day checks.
