— RPartStore Case Study

SmartSearch AI Car-Parts Sourcing

Replacing six disconnected tools with a unified AI conversation for garage counter staff and floor mechanics quoting under live repair pressure.

• Counter Tension

Six Hops Before the First Estimate

Professional buyers previously pivoted across six standalone tools to quote a single repair while customers waited at the desk.

The Legacy Workflow
SmartSearch ASE Solution

Fragmented Hop-by-Hop Sourcing

Single Continuous Session

1. VIN decoder 2. Catalog check (no fitment guarantee) 3. Labor operation lookup (frequently skipped) 4. Equivalent part cross-reference 5. Standalone estimate builder 6. Email delivery Result: Repeated VIN re-typing, zero fitment guarantees, and unbilled labor operations.

Vehicle context stays pinned throughout the conversation. Conversational query yields verified fitments, attached labor codes, and a client-ready estimate in one fluid timeline.

/ Synthesized Personas

Designed for Live Garage Contexts

Alex: Counter Buyer

Sami: Floor Mechanic

Needs a reliable 2-minute estimate while a vehicle owner stands across the desk. Prioritizes quick part availability, guaranteed fitment, and accurate labor pricing.

Orders directly from a mobile phone beside an elevated vehicle. Demands instant VIN scanning, clear country-of-provenance identification, and fast mobile dispatch.

■ Architecture Decisions

Four Signature Seam Reductions

D1. Conversational Thread UI

D2. Provenance Card Decoding

Rather than jumping between tabbed views, rich part cards render directly inside the chat thread with context preserved.

Flags regional manufacturing variances through WMI VIN parsing, preventing subtle cross-market fitment errors.

D3. Inline Labor Operations

D4. One-Motion Estimate Build

Welds standard labor time blocks directly to part selection cards, eliminating forgotten labor charges on client quotes.

Converts cart contents and linked labor codes into a customer-facing branded devis in a single action.

Target Omitted Labor Codes

Built on Ant Design 6 foundations customized for Motrio branding. Typography pairs DM Sans for UI text with JetBrains Mono for exact VIN and part reference legibility.

✱ Lean UX Method

Process & Open Questions

Executed under a Think-Make-Check cadence with 11 mobile screens (375x812) and desktop HTML prototypes. The following questions remain open prior to live validation:

1. Voice vs Text in Noisy Bays

2. Override Trust Limits

3. Direct WhatsApp Conversion

Will floor mechanics adopt speech-to-text queries in high-decibel shop environments, or default to manual VIN scans?

How frequently will senior counter staff override AI fitment confidence scoring when handling non-standard aftermarket parts?

Does messaging a PDF devis via WhatsApp decrease quote approval times compared to traditional email estimates?
