Tranzmile: Complex Platform Migration

Migrating a Legacy Umbraco Platform to Modern Shopify eCommerce with Custom Product Sync, Advanced Shipping Logic and Multi-Location Fulfilment for Tranzmile

Overview

Tranzmile is a leading Australian automotive parts supplier operating under the Truck & Trailer brand. The business serves a diverse customer base with an extensive catalogue of parts for trucks, trailers, 4WDs, stationary engines, engine rebuilds and related automotive applications across multiple locations nationwide.

Facing limitations with an unsupported 2010-era Umbraco website, Tranzmile partnered with 23 Digital to migrate to a modern, scalable Shopify platform. The project required far more than a standard platform migration—it demanded custom product synchronisation with Tranzmate, sophisticated shipping calculations across multiple carriers, multi-location fulfilment logic, and the preservation of critical SEO authority. The result is a reliable, maintainable eCommerce foundation engineered around complex business requirements.

The Objective

Tranzmile’s legacy Umbraco website had served the business since 2010, but the platform was no longer supported and had become a barrier to growth. The site struggled with outdated security, limited scalability, difficult product management and mounting technical debt.
Transzile needed a reliable, modern eCommerce platform capable of managing a large automotive parts catalogue, complex pricing structures, multi-location fulfilment, advanced shipping logic and deep integration with their Tranzmate business system.

  • Migrate from an unsupported Umbraco platform to Shopify
  • Develop custom integration with Tranzmate for product, pricing and inventory synchronisation
  • Build shipping logic to handle products with missing data, dangerous goods and oversized freight
  • Enable Click & Collect across multiple Australian depot locations
  • Support both member and retail pricing tiers
  • Preserve existing URLs, metadata and organic search authority throughout migration
02

The Challenge

Tranzmile’s existing website supported critical business operations but had reached the end of its technical life. The migration required not only a platform change, but a complete rebuild of product workflows, pricing logic, fulfilment processes and freight calculations.

The automotive parts industry adds layers of complexity. Products range from small components to oversized trailer parts, and many items require specialised handling, manual freight quotes or cannot be shipped online at all. Tranzmile needed a system capable of handling these exceptions while still providing customers with a seamless experience.

  • Managing thousands of SKUs with varying availability across multiple locations
  • Accommodating products without recorded weight or dimensions in shipping calculations
  • Handling dangerous goods, superseded items and manual-quote-only freight scenarios
  • Supporting differential pricing for trade members versus retail customers
  • Maintaining SEO performance during a full platform migration
03

The Solution

23 Digital built a custom Shopify solution designed around Tranzmile’s operational requirements. Rather than forcing the business into out-of-the-box Shopify functionality, we developed custom applications, integrated third-party APIs and engineered complex business rules to support product synchronisation, multi-location fulfilment and intelligent shipping workflows.

  • Custom Shopify application to synchronise product data, inventory levels, member pricing and retail pricing with Tranzmate via structured CSV imports and exports
  • Starshipit API integration to calculate real-time shipping rates across Australia Post and freight carriers
  • Custom shipping logic to exclude products flagged as dangerous goods, oversized, missing dimensions or requiring manual quotes
  • Multi-location Click & Collect configured to display the customer’s nearest depot and manage stock across multiple Australian fulfilment points
  • Comprehensive URL mapping, metadata migration and technical SEO validation to protect organic search performance
  • Structured migration plan, quality assurance and go-live support to minimise disruption
