Conversational Product Finder Across a 50,000-SKU ERP Catalogue

A Claude-powered chat widget embedded in the client's e-commerce front-end, connected live to a 50,000-SKU ERP catalogue (SAP, Dynamics, or Odoo). Customers describe what they want in plain language; the system runs real-time vector similarity search filtered by live stock and returns ranked picks with cross-sell suggestions — zero ERP or storefront code modified.

What We Built

Real-Time ERP Catalogue Sync

All 50,000 products — including stock levels, pricing, categories, and attributes — synced to pgvector every 15 minutes via ERP REST API. No stale results, no discontinued items in suggestions.

Natural Language Intent Extraction

Claude API parses customer requests — including vague, multi-attribute, or conversational queries — into structured search parameters covering category, material, size, price range, and use case.

Hybrid Search Engine

Vector similarity, keyword, and structured attribute filters executed as a single query — returning relevant results even when the customer's terminology doesn't match the catalogue's product names.

Live Stock & Pricing Filter

Out-of-stock and discontinued products excluded from all responses at query time. Live pricing applied per customer account tier where ERP supports it — no suggestions for items the customer can't actually buy.

Cross-Sell Suggestion Engine

Co-purchase clustering surfaces accessories, consumables, and complementary items alongside each primary result — increasing average order value per session.

JavaScript Snippet Deployment

The entire chat widget is deployed via a single embeddable JavaScript snippet. Zero changes to ERP configuration, storefront templates, or existing checkout flow required.
