01 · Common problems in automotive & parts

What we typically see in automotive & parts.

Vehicle parts catalogue ecommerce
VIN, registration and vehicle-application lookups against a technically correct parts catalogue.
Parts fitment ecommerce
Fitment rules, supersession chains and discontinued-part handling that prevent the wrong-part order from being placed.
Parts catalogue platform
Parts catalogues with PIM-governed technical attributes and regional variants, commonly delivered on Magento or Adobe Commerce where the catalogue depth and B2B model already fit.
Dealer and distributor pricing
Multi-tier pricing across dealers, distributors and direct consumers, with account-specific visibility.
Technical catalogue ecommerce
Answer-first search and merchandising that sits behind technical correctness, not in front of it.
Cross-border catalogue
Regional vehicle variants and homologation rules surfaced cleanly across territory storefronts.
VRM and registration lookup
UK VRM and EU registration enrichment against the parts catalogue with clear "no match" handling.
Core charges and exchange units
Surcharge handling for exchange units (alternators, starters, DPFs) and core returns tracked through the OMS.
Garage and trade account ordering
Garage accounts with trade pricing, credit and approver workflows alongside the retail consumer flow.
Image and diagram management
High-volume image and exploded-diagram management with consistent naming, versioning and PIM ownership.
Returns and warranty handling
Returns split by reason (wrong-part, warranty, change-of-mind) with credit notes raised back into the ERP.
Stock visibility and ERP/PIM handoff
Live stock against the ERP across central, regional and dealer locations, with a clean ERP/PIM handoff that keeps catalogue, pricing and availability aligned per market.

03 · Questions we get asked

Common questions.

Can ecommerce support vehicle and part fitment lookups?

Yes. Vehicle, registration and part-number lookups, fitment data and supersession rules are core to automotive parts ecommerce. The data model is built around how customers actually search.

How is part data kept accurate across thousands of SKUs?

Part data is held in a PIM with validation rules, supersession handling and channel-specific feeds. The storefront, marketplaces and sales tools all read from the same source.

Can you integrate with TecDoc, eCat or other automotive data sources?

Yes. Third-party catalogue and fitment data sources are integrated into the PIM and storefront where the client has access to them. The integration is treated as a governed data feed, not a one-off import.

Can ecommerce work for trade accounts and workshops?

Yes. Workshop and trade accounts see contracted pricing, account ordering, credit limits and account-specific catalogues, with the same fitment and search tools as retail customers.

How does ERP and stock by branch fit in?

Stock by branch or depot is read live from the ERP and surfaced on product, listing and checkout pages, with fulfilment rules per branch honoured at order time.

How is fitment data kept governed across large parts catalogues?

In the PIM, with validation rules, supersession handling and channel-specific feeds. Updates are workflow-driven rather than spreadsheet-driven, so the storefront, marketplaces and sales tools read from the same source.

Which commerce platforms are relevant for automotive parts?

iWeb work in this sector has run mainly on Adobe Commerce and Magento, where the team has direct project evidence. The same operational pattern applies on other commerce platforms where the architecture supports fitment lookups and trade accounts.

Do you have proof in automotive parts?

iWeb has direct project experience in automotive parts ecommerce. The work archive lists projects that are public; others can be walked through under NDA. iWeb does not claim a project it did not deliver.

How is seasonal demand handled in automotive parts?

The platform is sized for peak order volume, with caching, asynchronous order posting and monitored queues into the ERP. The fitment lookup is sized for peak query volume separately from the catalogue.

Does iWeb only work in automotive parts?

No. Automotive parts is one sector among several. The same operational patterns apply in other B2B and trade sectors where technical catalogues and account ordering are real.
