TecDoc fitment, engineered into Shopify. Every part, the right vehicle.
Mecaparts connects your TecDoc licence to your Shopify store. Customers search by vehicle, VIN or KBA number — and only see parts that fit.
Requires an active TecDoc data licence from TecAlliance. Don't have one yet?

Your data source. Our engine. Your storefront.
Mecaparts sits between TecDoc and Shopify. It does not resell data: it reads what your licence gives you and turns it into products, categories and vehicle search.
TecDoc
The aftermarket's catalogue standard, through your own licence.
- Articles & brands
- Vehicle linkages
- OE & cross-references
- Images, PDFs, criteria
Mecaparts
Imports, maps and keeps your catalogue in sync.
- Bulk import by article no.
- Rule-based categories
- Price & stock sync
- Field mapping & overrides
Your Shopify store
Shopify products, with fitment your customers can trust.
- Vehicle finder
- Fits / doesn't fit badge
- Compatible vehicles table
- OE number search
Fitment apps ask you to build the data. We read it.
Year-make-model apps were designed for hand-made fitment files. If you sell in Europe, you already have something far better: TecDoc.
| Criterion | Generic year-make-model apps | Mecaparts |
|---|---|---|
| Source of fitment | Spreadsheets you write and maintain | Your TecDoc licence |
| Vehicle identification | Year, make, model | Make–model–engine, VIN, KBA |
| Engine precision | Only if you enter it | Engine code, power, build years |
| OE & cross-references | Not included | Searchable in your store |
| Product content | Written by you | Specs, images and PDFs from TecDoc |
Three steps from licence to live catalogue.
- Step 1
Connect TecDoc
Enter your API key and provider ID. Mecaparts detects what your licence covers and enables the matching features.
- Step 2
Import your range
Upload a file of article numbers with prices and stock, or select parts directly in TecDoc.
- Step 3
Sell by vehicle
The vehicle finder and fitment information appear in your theme. Customers filter to their car.
“Will it fit my car?” — answered on the page.
Uncertainty is what stops a parts sale and causes returns. Every product page shows the evidence a buyer — or their mechanic — looks for.
| Vehicle | Engine | kW/PS | Years |
|---|---|---|---|
| Golf VII (5G1) | 2.0 TDI | 110/150 | 2012–20 |
| Octavia III (5E3) | 2.0 TDI | 110/150 | 2012–20 |

Who stands behind the software.
“I didn't set out to build another auto parts platform — I built Mecaparts because I saw how frustrating this industry can be when you're trying to do things right, but the tools just aren't there.”
Before you install.
Q.01Do I need my own TecDoc licence?
Yes. Mecaparts connects to your TecDoc API access from TecAlliance (API key and provider ID). What your store can show — VIN lookup, images, number of brands — depends on that licence. If you don't have one yet, book a call and we'll explain the options.
Q.02Which vehicle searches are included?
Make–model–engine search in every store. VIN search when your TecDoc subscription includes VIN. KBA (HSN/TSN) search for official German vehicle data as an add-on.
Q.03How do I import my inventory?
Upload a CSV or Excel file of article numbers with your prices and stock, add products one by one, or search TecDoc and add parts directly.
Q.04How many parts and vehicles will my store have?
It depends on your TecDoc access. Mecaparts brings the data your licence includes into Shopify and helps you organise and present it.
Q.05What happens after the trial?
Your plan is billed through Shopify every 30 days. Products above the plan's allowance are charged at its per-product rate. You can switch plans or cancel at any time.
Q.06What support do you offer?
Email support on every plan, priority support on Grow and dedicated support on Enterprise. We reply within 24–48 business hours, and the documentation covers setup step by step.
Q.07Can you build the store for us?
Yes — catalogue setup, theme development and custom integrations, from $95/hour with a 6-hour minimum, or as a full custom website project.
