Build a RAG Sales Chatbot for E-commerce with n8n (Live Stock + Product Q&A + Lead Capture)
Shoppers ask questions before they buy - about sizing, materials, compatibility, and availability. Most stores answer with a static FAQ or a slow email reply, and the sale cools off. A RAG-powered chatbot built in n8n answers instantly from your real catalog, checks live stock, and captures the lead.
Why RAG beats a scripted chatbot
Rule-based bots break the moment a customer asks something off-script. A RAG (retrieval-augmented generation) bot grounds every answer in your actual product data, so it responds accurately about any item without you writing a single canned reply.
Because answers come from your catalog rather than the model's training data, the bot won't invent specs or quote prices that don't exist - the failure mode that kills trust in AI support.
The architecture in n8n
The workflow has two halves: an indexing pipeline that keeps your product knowledge fresh, and a chat pipeline that answers in real time.
- Sync product descriptions, specs, and policies into a vector store
- On each question, retrieve the most relevant product chunks
- Call a live stock endpoint so availability is always current
- Generate a grounded answer with the retrieved context
- Capture name and email when intent is high, and push the lead to your CRM
⚡ RAG Sales Chatbot + CRM for E-commerce: Product Q&A, Live Stock Check & Lead Capture
Answer product questions accurately and capture every interested shopper.
Turning conversations into revenue
The bot isn't just support - it's a salesperson. When a shopper shows buying intent, it can recommend complementary products, confirm the item is in stock, and offer to send a cart link. Every conversation that reaches that point is logged as a lead.
Hand off to a human gracefully when the question is outside the catalog (returns disputes, custom orders) so customers never hit a dead end.
Keeping it accurate over time
Re-index when products change so the bot never quotes a discontinued item. Schedule the sync in n8n to run on a cron, and the knowledge base maintains itself.
