Let’s be honest: managing auto parts online isn’t just about uploading products.
It’s about accuracy, compatibility, and efficiency. And when you're dealing with 10,000, 50,000, or even 100,000 SKUs, things get complicated fast—especially if you're still doing everything manually.
If you’re stuck searching for OE codes online, copying specs from PDFs, uploading images one by one, and trying to figure out which part fits which vehicle, it’s time for a better solution.
That’s where Mecaparts and TecDoc come in—a powerful combination built to help serious auto parts sellers move faster, work smarter, and grow with confidence.
1. What Is TecDoc—and Why It Matters
TecDoc is the most accurate and widely trusted automotive catalog in the world. Built by TecAlliance, it gathers standardized data from over 900 verified part manufacturers and covers more than 110 million part numbers.
TecDoc provides:
- Product specifications and technical data
- OE references and cross-brand mappings
- Vehicle compatibility information by KType, KBA, and VIN
- Images, documentation, and product designations
This catalog is used by professionals across Europe to ensure product accuracy and compatibility. Unlike scattered data online or supplier PDFs, TecDoc is structured, verified, and always up to date.
If you're running an online auto parts store, you need product data you can trust—and TecDoc is the gold standard.
2. What Is Mecaparts—and How Does It Work?
Mecaparts is a Shopify app built specifically for auto parts sellers. It connects your product catalog to TecDoc and simplifies how you manage and publish your parts online.
Here’s how it works:
- Upload your product references: You start with a CSV file or enter part numbers manually.
- Mecaparts connects to TecDoc: It finds the correct part in the TecDoc database.
- Automatic enrichment: The app pulls in the part’s specifications, title, technical data, images, documentation, and compatible vehicles.
- Ready to publish: Enriched listings are added directly to your Shopify store—no manual editing or formatting required.
You can also use the built-in TecDoc catalog browser inside Mecaparts to search by designation, reference, or manufacturer, even without uploading anything. This gives you full access to explore parts, verify data, and find what you need, fast.
3. Manual Management vs. Smart Catalogs
Here’s what the traditional process looks like for many sellers:
- Search each part number online
- Copy product specs from PDF files or supplier emails
- Upload product images manually
- Try to figure out vehicle fitment using forum posts or spreadsheets
- Repeat for thousands of products
Now compare that with the Mecaparts + TecDoc workflow:
- Upload a file or enter a part number
- Mecaparts finds and enriches the data instantly
- Push clean listings to your Shopify store
- Display precise vehicle compatibility with no manual effort
The result is a catalog that’s consistent, professional, and far easier to manage—without the errors, delays, or return issues that come with doing everything by hand.
4. What You Can Import with TecDoc
Once connected, Mecaparts pulls detailed and structured data directly from TecDoc. This includes:
- Product names and designations
- Manufacturer and OE references
- Technical attributes (material, dimensions, system type, etc.)
- High-quality images and documents
- Vehicle compatibility by KType, KBA, or model
Whether you sell filters, sensors, brake pads, or body parts, this information helps ensure your listings are accurate, complete, and trustworthy.
And when customers know a part is the right fit, they're far more likely to buy.
5. Fixing the Compatibility Problem
Incorrect fitment is one of the biggest reasons for returns in the auto parts industry.
Mecaparts solves that with integrated vehicle compatibility data from TecDoc. You can match parts to specific vehicles using KTypes, KBA numbers, or brand/model filtering. Your customers can then browse only the parts that fit their car, reducing confusion and frustration.
There’s also a built-in VIN Search tool to help identify the correct vehicle, though this tool is for lookups only—not for importing data.
By showing accurate fitment upfront, you lower your return rate, improve customer satisfaction, and build trust.
6. Built Exclusively for Shopify Sellers
Mecaparts is currently available only on Shopify, which means everything we build is optimized for that ecosystem.
You don’t need to worry about compatibility or complex integrations. You can:
- Publish enriched listings directly to your Shopify store
- Use Shopify’s native categories, filters, and tags
- Track performance through Shopify analytics
Whether you’re selling B2C or B2B, Mecaparts gives you the tools to manage a professional-grade catalog without hiring a tech team or building a custom solution.
7. Designed to Scale With You

You can:
- Upload and enrich tens of thousands of parts in bulk
- Organize your store by brand, category, or vehicle type

If you’ve struggled with messy spreadsheets, unreliable supplier files, or endless product edits, this is the solution you’ve been waiting for.
Final Thoughts
Running an online auto parts store is already complex. You have to manage a large inventory, keep customers happy, and stay ahead of the competition.
