Case: A New Marketplace for Used Car Parts – Sustainable, User-Friendly, and Scalable

Using Atracco's websites, both consumers and repair shops can search among more than 2 million unique original car parts, with full assurance that the parts fit their specific vehicle. In addition to cutting costs for customers, reusing parts contributes to significant environmental savings by reducing emissions and conserving resources.

The development project began in December 2024, and the new websites were launched in May 2025.

UX Challenge: Helping Users Navigate 2 Million Unique Products

Every car part sold through Atracco is a one-off item. That means users must be able to quickly and confidently determine:

• Does this part fit my car?
• Is it still in stock?
• Where is the nearest repair shop?

To meet these needs, a clearly defined purchase journey – or “happy flow” – was designed to guide visitors from the homepage to the right part using intuitive call-to-actions.

There are two primary entry points to the journey: users can search by vehicle registration number or part number. This instantly filters the full catalog into a relevant, manageable context. From there, users can refine their search using filters, faceted navigation, and categories, making it easy to find exactly the right part for their vehicle.

To simplify the decision-making process even further, users can also compare similar parts that are compatible with the same car.

Building Buyer Confidence

To ensure buyers feel confident that the part will work with their vehicle, several key features were implemented:

• A quality grading system for parts
• Warranty levels tied to the quality grade
• Real-time stock visibility

Real-Time Reservation Flow

One of the solution’s most critical components is the reservation system, which guarantees that a part is actually available before the customer proceeds to checkout.

As soon as an item is added to the cart, a live reservation is triggered in Atracco’s ERP system, Recopart. This reduces the risk of failed purchases and gives buyers peace of mind knowing the part is secured at their chosen car repair shop.

Technical Solution – Scalable, Fast, and Robust

The websites were built on Litium Commerce Cloud, with an integration with Atracco’s custom-built ERP system, Recopart:

• To ensure scalability and handle millions of products, a Private App was developed within Litium Cloud, supporting caching and temporary storage of product data, prices, and stock levels. The integration supports both batch transfers and real-time updates for orders, stock, and reservations.
• Performance was a top priority to enhance user experience and conversion. Both sites were optimized for speed and accessibility, across desktop and mobile, resulting in top performance scores:
  
• To achieve strong SEO and GEO ranking, special attention was given to data structure and rich URLs – for example, URLs that include the car make and model such as: https://www.allabildelar.se/bildelar/audi/audi-80-79-84 – along with custom-built panels in Litium CMS to support the creation of hundreds of AI-generated landing pages.
