Unified automotive commerce, built for real complexity.
Fitment data that drifts. ERP and storefront out of sync. Wholesale, DTC, and POS on separate stacks. We build the architecture that resolves it - natively on Shopify.
Where automotive commerce gets complex
Fitment outside the data model
When fitment logic lives in a connector layer rather than the core data model, it drifts. ERP updates, PIM restructures, and vendor feed changes push compatibility data out of sync with the storefront. Wrong-part returns follow.
Catalog scale without search degradation
Most search implementations perform acceptably below 100K SKUs. Above 500K, relevance breaks and zero-result pages leak revenue that never shows up in analytics - just exit rates.
Multi-buyer operations on separate stacks
Wholesale, DTC, and POS running as separate systems means tripled integration surfaces, pricing discrepancies, and every catalog change applied three times.
One architecture. Every buyer type. Every channel.
Teifi Parts embeds YMM into Shopify's data model - persistent vehicle selection, fitment-filtered search, and SKU-to-application mapping at scale.
Shopify B2B for trade accounts, standard DTC for retail customers, and POS for counter sales - all on the same platform, same inventory, no duplication.
Teifi Bridge handles integration to NetSuite, SAP, and aftermarket data suppliers - syncing pricing, inventory, and catalog updates without manual intervention.
500K+ SKUs with fitment filtering that stays fast. Structured catalog taxonomy, metafield-driven attributes, and search built for parts - not generic products.
