AI-Powered E-commerce Chatbot That Drives Sales & Cuts Support Load

Problem

The client – a mid-sized fashion e-commerce brand with over 12,000 SKUs and a growing online audience across web and WhatsApp was facing a critical operational bottleneck. High pre-purchase queries, repetitive support tickets, and abandoned carts were stalling conversions and inflating service costs. While the catalog was rich and diverse, customers struggled to navigate complex product filters and discover relevant apparel intuitively.

Customer support teams were overwhelmed by repetitive FAQs (COD, returns, delivery times), often leading to slow responses and dropped purchase intent. Additionally, the brand’s multilingual audience, primarily English, Hindi, and Gujarati speakers, needed natural, conversational assistance not robotic menus or static help pages.

Key Challenges

• Discovery issues: Users struggled to describe specific outfit needs through current filters.
• Support overload: Most chat queries (60–70%) were repetitive pre-purchase questions.
• Cart drop-offs: Many users abandoned carts at checkout with no automated recovery.
• Language gap: Non-English shoppers couldn’t browse or buy comfortably.
• High support cost: Manual repetitive replies slowed the team and reduced conversions.

Solution

BytezTech engineered a multilingual AI commerce assistant built to blend intelligent discovery, guided selling, and real-time reasoning into a unified conversational experience across both website and WhatsApp. The chatbot was designed to understand natural language, product context, and apparel-specific nuances like size, fabric, and occasion wear. Leveraging LangChain + FastAPI, vector search, and GPT-class LLMs, it became both a stylist and a sales associate, driving engagement and automating support.
