6,000+ Variants Matched to Every Vehicle: How Wipertech Rebuilt Automotive Retail on Medusa

Wipertech is the leading online retailer of automotive wiper blades, serving customers across Australia and New Zealand. Selling wipers online is deceptively complex: customers shop by their vehicle's make, model, and year, not by blade length or connector type. Matching the right product to the right car means managing thousands of fitment relationships behind the scenes. To support its growth and handle this complexity, Wipertech turned to 306 Technologies, a Medusa partner, to rebuild its commerce foundation.

By migrating to Medusa, Wipertech launched a multi-region storefront powering 3,000+ vehicle applications, 6,000+ vehicle-specific product variants and kits, and thousands of fitment relationships, all managed from a single centralized platform.

Most commerce platforms just aren't built for the complexity of vehicle fitment. Medusa gave us the flexibility to model it exactly the way Wipertech needed, without fighting the framework.

The Challenge: A Legacy Platform That Couldn't Scale

Selling wiper blades online is more complex than most people realize. Customers don't search by technical specifications, they search by their vehicle. Delivering a seamless experience means accurately matching thousands of wiper combinations to specific makes, models, and years, so customers can find the correct product without ever needing to understand the underlying fitment data.

As the business grew, Wipertech's existing Craft Commerce platform became increasingly difficult to scale. It wasn't built to handle the complexity of vehicle fitment data, multi-region operations, custom integrations, and evolving customer experience requirements.

The core challenges:

• Complex fitment data: Thousands of wiper-to-vehicle relationships that had to be matched accurately at scale.
• Multi-region operations: A need to serve both Australia and New Zealand, each with its own products, inventory, pricing, and fulfillment.
• A platform hitting its limits: A legacy Craft Commerce setup that couldn't support custom integrations or continued growth.

The Solution: A Custom Commerce Platform Built on Medusa

Wipertech rebuilt its commerce foundation on Medusa, migrating off Craft Commerce and going live in June 2026. The result is a custom platform designed around Wipertech's vehicle-first shopping experience: customers quickly find compatible products based on their vehicle, while thousands of fitment relationships are managed behind the scenes to ensure accurate recommendations across a wide range of vehicle applications.

Deployed on Medusa Cloud, Medusa serves as the source of truth for all commerce data, including products, variants, inventory, pricing, customers, and orders, and orchestrates how that data flows across the storefront, ERP, fulfillment, and analytics integrations. Sanity CMS handles the content layer: landing pages, navigation, imagery, and merchandising, roughly 95% of which can be managed without code changes. Products are synced from Medusa into Sanity so editors can feature them in content without duplicating the underlying commerce data. Beyond content, the platform integrates with Wipertech's ERP, fulfillment providers, marketing tools, analytics platforms, and customer engagement systems.

A Vehicle Compatibility Engine

One of the most complex aspects of the platform was managing vehicle compatibility. Because products are selected by vehicle rather than by traditional product attributes, the platform manages thousands of fitment relationships across makes, models, years, and variants, so customers can identify compatible products quickly, with fewer purchasing errors and support inquiries.

The raw vehicle data comes from a global part catalog platform, a manufacturer-level source far more granular than what a customer needs, a single "2014 Lexus" can map to 20+ distinct records split out by engine type, capacity, and other specs. To bridge that gap, 306 Technologies built a custom Data Orchestration layer directly into Medusa that imports and normalizes the part catalog data, groups those records into customer-friendly vehicle selections, and maps each to the appropriate Wipertech SKUs and fitments.

When a customer selects their vehicle, the platform resolves it against the fitment relationships in Medusa and returns the compatible products. Because the orchestration layer sits between the part catalog platform and the rest of the system, the upstream source can be swapped or extended later without major changes to the storefront or Medusa's core commerce. Medusa's modular architecture made it possible to model this custom fitment logic cleanly, extending the platform with domain-specific data and integrations without rebuilding core commerce functionality from scratch.

We migrated fully to Medusa, including more than 800,000 historical orders and a completely rebuilt frontend, in just over four months. Orders from 10 years ago now appear in search almost instantly, and we can roll out a new market in weeks, not months.

A Connected Commerce Ecosystem

Beyond the storefront, the platform was designed to support the operational workflows that power the business. Orders, inventory, fulfillment, customer communications, and reporting are connected through automated workflows that reduce manual administration and improve the flow of information across the organization.

This lets the Wipertech team manage day-to-day operations more efficiently while maintaining visibility across multiple systems, regions, and business functions.

Multi-Region Commerce Operations

The platform supports both Australia and New Zealand from a single centralized admin, while allowing each region to maintain its own products, inventory, fulfillment workflows, pricing, and customer experiences. Built with scalability in mind, it can support additional regions, fulfillment providers, warehouses, and inventory locations as requirements evolve, giving Wipertech the flexibility to rapidly expand into new markets while keeping operations consistent.

A Scalable Foundation for Growth

The completed platform replaced Wipertech's legacy Craft Commerce implementation with a modern commerce architecture built specifically for automotive fitment. Customers now identify compatible products through vehicle-based search and compatibility tools, while internal teams manage inventory, content, orders, fitment data, and operations from one centralized platform.

With support for 3,000+ vehicle applications, 6,000+ product variants, thousands of fitment relationships, and integrations across key business systems, Wipertech is well positioned for continued growth across Australia, New Zealand, and future markets.
