AUTOCARAT: Shopify Plus Multi-Vendor Auto Parts Marketplace with TecDoc, Acumatica and Pimcore
Platform selection, UX design and development that turned AUTOCARAT's non-transactional website into a multi-vendor auto parts marketplace serving Germany, Poland and France, on Shopify Plus with a 50,000+ product TecDoc-based catalog, Acumatica ERP and Pimcore PIM.
Project Summary
Elogic Commerce turned AUTOCARAT’s website, which had no ecommerce functionality, into a multi-vendor auto parts marketplace for a Germany-based business operating in Germany, Poland and France. Elogic led the project end to end, starting with discovery services that compared Shopify and BigCommerce, then UX design, development, integrations, testing and launch. The project took eight months, followed by three weeks of stabilization.
The marketplace runs on Shopify Plus with multi-vendor marketplace functionality. Pimcore manages product content and prices, Acumatica ERP manages stock and orders, and TecDoc supplies fitment data. TecDoc data gives buyers structured part information and vehicle compatibility across more than 50,000 products. Vendors register and are verified before they sell, and buyers search and filter by car model, part type, condition and manufacturer. The marketplace serves buyers in German, Polish, French and English and now brings together more than 450 suppliers and more than 5,000 customers.

About the Client
AUTOCARAT is a Germany-based online marketplace for auto parts, operating in Germany, Poland and France and bringing multiple vendors and their buyers onto one platform. Rather than run its own inventory, AUTOCARAT connects independent sellers with buyers looking for the right part.
Auto parts are hard to sell online without good data. Buyers need to know a part fits their vehicle before they order, and a marketplace has to present listings from many vendors in a consistent, searchable way.
Project Complexity
AUTOCARAT’s website had no ecommerce functionality, so the marketplace, from catalog structure and checkout to vendor workflows, had to be defined and built as a new commerce layer.
Parts had to be identified by structured attributes and vehicle compatibility, not just names. Fitment data from the TecDoc API had to be mapped to product content from Pimcore and kept up to date automatically in Shopify Plus.
Shopify and BigCommerce both had to be assessed against marketplace, catalog and integration requirements before any build began.
Product content and prices live in Pimcore, stock and orders in Acumatica, and fitment data in TecDoc. The marketplace had to bring all three together so buyers see consistent, accurate information.
Suppliers needed to register, pass verification, manage their own listings and track their sales, with supplier-specific pricing, while the marketplace kept a consistent buyer experience across all sellers.
The marketplace had to serve buyers in Germany, Poland and France in German, Polish, French and English, with prices in euro and Polish złoty with tax and shipping calculated from the buyer’s location.
Business Challenge
01
AUTOCARAT's website had no ecommerce functionality, and the business needed a full multi-vendor marketplace, not a single-seller store
02
The right platform, Shopify or BigCommerce, still had to be chosen
03
Buyers had to find compatible parts quickly in a large, technical catalog
04
Product data had to come from TecDoc automatically rather than being entered by hand
05
The marketplace had to connect to Acumatica ERP and Pimcore PIM from launch
06
Vendors needed a simple, verified way to join and manage their listings
07
The experience had to work across Germany, Poland and France in four languages
Elogic Commerce's Solution
Discovery and platform selection
Elogic Commerce ran discovery services covering stakeholder interviews, functional requirements and the backlog. The team compared Shopify and BigCommerce against AUTOCARAT’s marketplace, catalog and integration requirements, recommended Shopify, and designed the architecture and data integration flows before development started.
UX design
Elogic Commerce created a style guide, low-fidelity wireframes to prove the UX concepts, and high-fidelity layouts and prototypes for the full buyer and vendor journey, reviewed with stakeholders before build.
Shopify Plus marketplace foundation
The marketplace was built on Shopify Plus with multi-vendor marketplace functionality, configured for German, Polish, French and English, euro and Polish złoty, across three markets, with a catalog hierarchy suited to auto parts.
TecDoc fitment integration
Elogic Commerce built a secure API integration with TecDoc and mapped its fitment data to the product catalog, so buyers can check vehicle compatibility on every relevant part. A scheduled sync keeps the data current, and an integration log tracks every run.
Acumatica ERP and Pimcore PIM integration
Elogic Commerce connected Shopify Plus to both systems with a clear split of data ownership. Pimcore supplies product content and prices, and Acumatica manages stock and orders, so each type of data has one source and the storefront stays consistent with AUTOCARAT’s back office.
Search, filtering and product pages
Buyers can filter by car model, part type, condition (new or used), manufacturer and price. Product pages show compatibility, condition, vendor details and zoomable images, with reviews, ratings and labels highlighting popular items.
Vendor onboarding and dashboard
Suppliers register and create a profile, pass a combined automated and manual verification based on their documents, and manage listings, supplier-specific pricing, sales and customer inquiries from their own dashboard.
Checkout and customer accounts
Checkout calculates tax and shipping from the buyer’s location and sends automated order confirmations and invoices. Buyers have accounts with order tracking, returns, purchase history and wishlists.
Testing and launch
The team ran functional, integration, security and user acceptance testing, prepared user guides and training, and stabilized the platform over three weeks after launch.

When This Solution Is a Good Fit
A Shopify Plus marketplace with TecDoc, ERP and PIM integration fits when the business needs multiple vendors, a large technical catalog and structured compatibility data from day one, and wants a platform it can extend over time. Starting with discovery and a structured platform comparison keeps the build focused on what the marketplace actually needs at launch.
It is generally not the right fit for a single-brand store with a small catalog, or for businesses that do not need vendor management, where a standard ecommerce platform will be faster and cheaper to launch.
Planning an Ecommerce Transformation?
If you are planning an auto parts marketplace or a multi-vendor platform, Elogic Commerce can take you from discovery and design to a working marketplace with the catalog data, vendor tools and integrations it needs.
