The website is only
the visible part.
Selling automotive parts online is fundamentally different from selling most other products.
A customer buying a shirt chooses a colour and size.
A customer buying an automotive part may need to identify the correct make, model, series, year, engine, transmission, body, drivetrain or vehicle variant before they can even determine whether the product is suitable.
In a dealership or parts store, an experienced parts interpreter can solve that problem across the counter.
Online, the data has to do the interpreting.
That is why successful automotive ecommerce depends on much more than a well-designed webstore. Fitment data, product information, system integrations, inventory, marketplaces, freight, internal processes and the customer journey all need to work together.
A beautiful automotive website sitting on unreliable, incomplete or poorly structured compatibility data can confidently sell somebody the wrong part.
We fix the foundations first.
The connection between a part
and the vehicles it fits.
Automotive fitment is the process of identifying and recording which specific vehicles or motorcycles a part or accessory is compatible with.
Depending on the product, compatibility can be broad or extremely specific.
A floor mat might suit numerous models within a vehicle series. An engine, fuel, braking or electronic component may suit only particular variants fitted with a specific engine, transmission or other configuration.
Fitment turns that compatibility knowledge into structured data that can be used by your:
- Automotive parts finder
- Webstore search and filtering
- Product pages
- Compatibility badges
- Shopping cart
- Rego or VIN lookup
- Customer vehicle garage
- eBay listings
- Marketplace channels
- PIM, ERP or DMS integrations
Without accurate fitment, customers are left to work compatibility out for themselves.
That creates hesitation.
And hesitation costs sales.
Wherever you are today,
we can start there.
AUTO DEALERSHIPS
Unlock $$$ by taking your parts department online.
If you are an OE car or motorcycle dealership considering selling genuine parts, accessories or merchandise online, the first decision should not be which website platform to buy.
We help you work through the bigger picture first:
- What should you sell online?
- Which products offer the strongest commercial opportunity?
- Where will the product and fitment data come from?
- How will the webstore connect with your existing systems?
- Should marketplaces such as eBay be included?
- How will inventory, orders and fulfilment flow?
- Who will operate the online channel after launch?
- How will customers confidently identify the correct parts?
Then we design the technology and implementation around the right customer experience for your dealership.

The customer-facing part finder is the easy bit to see.
What matters is what sits underneath it.
ZELLIS Auto is our suite of automotive fitment solutions designed to structure, manage, tag and deploy vehicle compatibility across ecommerce channels.
Depending on your business, we can work with:

Redbook provides detailed Australian vehicle and motorcycle definitions and is widely used across the Australian automotive industry. ZELLIS Auto leverages Redbook vehicle data to power compatibility tagging and customer-facing fitment experiences where an Australian-market vehicle definition is the right fit for the project.

TecDoc is a widely used automotive aftermarket vehicle and parts data standard maintained by TecAlliance. For businesses selling aftermarket products, TecDoc can provide a powerful foundation for vehicle compatibility and may also allow existing manufacturer fitment relationships to be leveraged rather than recreated manually.

The objective is not to sell you a particular data source. It is to establish the most appropriate fitment foundation for what you sell and how you sell it to maximise your online sales revenue.
Automotive ecommerce is
an ecosystem.
Fitment may be central to automotive ecommerce, but it does not operate in isolation.
That is where ZELLIS is different from a company selling a standalone parts finder or vehicle database.
We work across the entire online operation.

Automotive ecommerce succeeds when these pieces support each other.
This is the ZELLIS approach.
Questions, Answered.
Automotive fitment, also called vehicle compatibility or parts compatibility, is the process of identifying which specific cars, motorcycles or vehicle variants a part or accessory fits. This compatibility data can then power parts finders, product filters, compatibility messages, marketplaces and other ecommerce functionality.
In most cases, yes. ZELLIS Auto can be deployed with existing ecommerce environments where the required product data and suitable integration access are available. We assess the platform, data and integration requirements before recommending an implementation.
It depends on the products you sell, your existing data and the customer experience you want to create. ZELLIS supports multiple approaches including Redbook, TecDoc and appropriate custom vehicle data. We assess suitability rather than automatically recommending the same dataset to every business.
TecDoc is an automotive aftermarket data standard maintained by TecAlliance. Vehicle definitions use TecDoc identifiers, commonly referred to as KTypes, which can be associated with automotive products to establish compatibility.
If you’re licensed for TecDoc, yes. ZELLIS Auto includes eBay fitment. Whether your webstore fitment data can be used on eBay will depend on your vehicle dataset, ecommerce platform and available marketplace integrations. ZELLIS is an eBay Partner for automotive fitment solutions and can assess how compatibility should be managed between your core product data, webstore and eBay listings.
Yes. ZELLIS can work on an existing automotive webstore or provide a broader ecommerce solution encompassing strategy, product and fitment data, customer experience, design, development, integrations, marketplaces and ongoing optimisation.
Start with discovery rather than a website quote. We first evaluate your commercial opportunity, catalogue, data, systems, marketplaces, processes, internal resources and fulfilment requirements. From there we can recommend a practical sequence for launching your parts online.
Yes. Low conversion in automotive can be caused by fitment gaps, poor product data, difficult search and navigation, insufficient compatibility reassurance, pricing, freight, technical issues or other customer journey friction. We can audit the operation to identify where the strongest opportunities sit before deciding what should be changed.
Stop making customers guess
Whether you are launching an automotive parts webstore for the first time or improving an established online operation, the objective is the same:
Help customers find the right part quickly, understand why it is right, and feel confident enough to buy it.
We can help you work out what is getting in the way.
No pressure.
No generic sales pitch.
