How to automate GST-compliant WhatsApp quotations in 2026
Most wholesalers, distributors, and small manufacturers in India still handle quotations manually on WhatsApp — typing prices, calculating CGST/SGST/IGST by hand, and losing hours every day. This guide walks through the modern, AI-driven workflow you can put in place this week.
1. Why WhatsApp is the quoting channel in India
Buyers already send enquiries on WhatsApp — voice notes, photos of samples, scribbled BOMs. Email is a distant second. The winning sellers meet buyers on the same channel and respond in minutes, not hours.
2. The GST maths you can automate
Every line item has an HSN code and a GST slab (usually 5%, 12%, 18% or 28%). Intra-state sales split into CGST + SGST; inter-state sales use IGST. An AI quoting tool should read the item, look up the slab from your catalogue, and place the correct split on the quotation PDF automatically.
3. Handle voice notes in any Indian language
Modern speech models transcribe Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada, Malayalam, Bengali, Punjabi and code-mixed English cleanly. Feed the transcript to an LLM with your catalogue as context and it can extract the SKUs and quantities the buyer asked for.
4. Generate a branded PDF the buyer will accept
Buyers still expect a proper quotation PDF with your logo, GSTIN, bank details, and terms. Automate the template once — the agent fills in the line items and totals, then sends the PDF back on WhatsApp with a short summary message.
5. Close the loop with payments and follow-ups
Attach a Razorpay payment link to the quotation and set the agent to nudge silent leads after 24 and 72 hours. Most of the revenue lift comes from the follow-ups no human ever finds time for.
