Selling auto parts online is not just about uploading products. Success depends on accuracy, compatibility, and trust. If a customer can’t be sure that a part fits their vehicle, they won’t buy it. That’s why TecDoc — the most comprehensive and reliable automotive catalog — has become the backbone of many eCommerce solutions.
But here’s the challenge: integrating TecDoc with an online store is far from simple. Between licensing requirements, technical integration, and ongoing maintenance, the process can quickly turn into a costly, resource-heavy project. Unless, of course, you use a dedicated solution like Mecaparts.
In this article, we’ll walk through how TecDoc integration works, what it typically costs, and why Mecaparts is changing the game for auto parts sellers.
1. What is TecDoc and Why Does It Matter?
TecDoc, developed by TecAlliance, is the world’s most accurate and trusted automotive parts catalog. It aggregates OEM and aftermarket data from thousands of manufacturers, providing detailed references, fitment information, and technical specifications.
For online retailers, TecDoc ensures:
- Customers can search by vehicle, VIN/KBA, or OE number.
- Product details like specifications, dimensions, and images are standardized and reliable.
- Compatibility issues are minimized, reducing returns and increasing trust.
Simply put: TecDoc is the foundation of a professional auto parts eCommerce store.
2. The Challenge of Integration
While TecDoc is powerful, it wasn’t built to connect directly with eCommerce platforms like Shopify or Magento out of the box. That means businesses face two major hurdles:
- Licensing: You must purchase access directly from TecAlliance.
- Technical Development: A custom integration layer must be built to pull TecDoc data into your store.
And here’s where things get tricky. TecDoc’s raw data is massive — millions of references, compatibility mappings, and media files. Without the right technical setup, your store can’t make sense of it.
3. How TecDoc Integration Works (The Technical Side)
Integrating TecDoc usually involves several steps:
- API Connection: Most modern integrations use the TecAlliance Web Services API (SOAP or REST). This allows your system to request product, vehicle, and compatibility data in real time.
- Database Management: Because TecDoc’s dataset is huge, developers often set up a local database (MySQL, PostgreSQL, or similar) to cache and structure the information for faster queries.
- Programming Languages: Depending on the platform, developers might use PHP, Python, or Node.js to handle data requests, process fitment logic, and sync information with your eCommerce backend.
- Mapping & Synchronization: The real complexity lies in mapping TecDoc’s structured data (vehicle types, attributes, OE numbers) to your store’s product catalog. This requires constant synchronization to keep data updated.
- Front-End Search Tools: On the user side, developers must build a vehicle selector or VIN/KBA search tool to let customers find the right part quickly.
Done right, this gives you a powerful, TecDoc-backed online store. Done wrong, it leads to slow performance, mismatched parts, and frustrated customers.
4. The Budget Question
Here’s the part many businesses underestimate: cost.
The cost of a TecDoc integration can vary widely depending on scope.
- A basic TecDoc integration—where TecDoc data is connected to your existing store and made searchable—typically starts around $4,000–$5,000.
- A full-scale store build, on the other hand, is a different project altogether. This doesn’t just mean TecDoc integration, but also includes custom design, multiple payment methods, CRM integration, ERP connections, user roles, advanced analytics, and other enterprise-level features. Such projects can range anywhere from $50,000–$100,000, depending on complexity and customization needs.
With Mecaparts, you don’t need to start from scratch or invest in a six-figure build. Our Shopify-native app already integrates TecDoc data, vehicle selectors, and product management tools—so you get enterprise-level functionality without enterprise-level costs.
5. Why Mecaparts is a Smarter Alternative
This is exactly why we built Mecaparts. Instead of reinventing the wheel with a costly, one-off integration, Mecaparts provides a ready-to-use Shopify app that handles TecDoc data for you.
With Mecaparts, you get:
- Seamless TecDoc access inside Shopify — no custom dev required.
- Vehicle selector, VIN/KBA search, and category management already built in.
- Automated imports that save you hundreds of hours.
- Predictable subscription pricing, instead of unpredictable dev bills.
- Faster time to market, since setup happens inside Shopify’s familiar environment.
In other words: Mecaparts delivers the benefits of TecDoc without the headaches of building (and constantly maintaining) a custom integration.
Final Thoughts
TecDoc is essential for any serious auto parts seller. But integrating it into your online store has traditionally been a complex, expensive process. From backend infrastructure to front-end search tools, the amount of work (and budget) required is significant.
Mecaparts changes that. By offering TecDoc integration as a plug-and-play Shopify app, it makes professional-grade auto parts eCommerce accessible to businesses of all sizes — without the high development costs.
If you want to grow your auto parts business with the power of TecDoc, Mecaparts is the smarter, faster, and more cost-effective way to get there.
FAQs
1. Do I need a TecDoc license to use Mecaparts?
Yes. TecDoc is managed by TecAlliance, and you’ll need an active license from them to access their catalog. Mecaparts handles the integration, but the license must be purchased separately.
2. Why use Mecaparts instead of building my own TecDoc integration?
Custom integrations require developers, ongoing maintenance, and high upfront costs. Mecaparts gives you a ready-to-use Shopify solution that’s faster, more affordable, and easier to scale.
3. How long does setup take?
Once your TecDoc license is active, Mecaparts can be set up in just a few hours — compared to months of custom development work.
