Qzenchat
An AI-powered conversational commerce and customer support platform that turns WhatsApp, Messenger, Instagram, and webchat into one connected storefront and help desk.
Overview
Qzenchat gives small and mid-sized businesses one workspace for customer conversations, orders, bookings, and fulfillment. An AI assistant understands each merchant's catalog and services, responds in the customer's language, helps complete purchases or appointments, and hands conversations to staff when a human is needed.
Key results
The Problem
Businesses selling through WhatsApp, Messenger, and Instagram often manage conversations manually while keeping orders, stock, bookings, and courier arrangements in separate chats, notebooks, or spreadsheets. Slow replies cost sales, scattered information causes mistakes, and multilingual customers are poorly served by one-size-fits-all tools.
Our Solution
We designed Qzenchat as a multi-tenant conversational commerce platform with a unified inbox, merchant-specific AI knowledge, conversational checkout, appointment booking, inventory controls, courier dispatch, and human takeover. Redis and BullMQ queue webhook processing reliably, while provider-neutral channel and logistics contracts keep integrations replaceable as the platform grows.
Challenges We Overcame
True Multi-Tenant Isolation
Every conversation, order, product, booking, and AI setting must remain scoped to the correct merchant workspace while many businesses share the same infrastructure.
Reliable Multi-Channel Messaging
WhatsApp, Messenger, Instagram, and webchat use different providers and webhook contracts. Deduplication and queued processing keep spikes, retries, and slow AI responses from dropping or duplicating messages.
Grounded Multilingual AI
The assistant must follow language switches without losing conversation context and answer only from verified catalog, stock, and availability data. Uncertainty must lead to a human handoff rather than an invented answer.
Concurrency-Safe Commerce
Inventory reservations and appointment holds need race-condition-safe workflows so two customers cannot purchase the last item or claim the same time slot.
Provider-Neutral Operations
Courier dispatch, tracking, payment rails, and bring-your-own-AI credentials are designed around replaceable contracts so regional providers and model vendors can be added without reworking the core product.
