Proposal

WhatsApp AI Sales & Support Agent

Prepared for Saptaveda Herbals Private Limited

Right now your orders are closed by hand. A customer messages on WhatsApp, someone reads it, answers questions, confirms the product, arranges payment, and follows up. It works only when a person is free and fast, and every slow reply is a sale lost. We propose an AI agent that runs on your existing number, +91 97780 09338, around the clock. It understands and replies in whichever regional language and script your customer writes or speaks in, including Malayalam and Manglish, knows your full catalogue and each customer's order history, closes the sale with a secure checkout, and guides customers to a doctor consultation when they need one.

✓ Your doctors work unchanged

They keep using the WhatsApp Business App and their labels for patient chats. The AI runs alongside on the same number and hands each conversation to the right doctor with full context.

✓ Safe by design

The agent never diagnoses and never invents health claims. Any medical question is routed to your licensed doctors, which keeps you compliant and turns questions into booked consultations.

What the agent does

01Closes sales automatically

Recommends the right product, confirms the details, and sends a secure checkout link. Customers pay by UPI, card, or Cash on Delivery.

02Knows your catalogue and customers

Trained on every product, price, and policy. Recognises returning customers and can reference their past orders.

03Answers support, 24/7

Order status and tracking, delivery questions, returns, and correct product usage, handled instantly at any hour.

04Routes to your doctors

Reads when a customer needs medical guidance and moves them to book a consultation with your Ayurveda doctors.

05Follows up after consultations

After a consultation, it follows up on the recommended products, closes the sale, and can prompt a follow-up visit.

06Speaks their language

Every regional language your customers use, replying in whichever style, including Malayalam and Manglish, that they write to you in.

Built around your current setup

Shopify backend

Stays your single source of truth for products, orders, and customers. The agent reads and writes through it.

Your WhatsApp number

The agent runs on +91 97780 09338 alongside the Business App, so nothing changes for your doctors.

Appointment bookings

It shares your booking link and detects completed consultations, without disturbing your current tool.

Facebook & Instagram ads

Click-to-WhatsApp leads from your existing ad funnel land straight in the agent, ready to close.

Shopflo checkout

Checkout links route through your Shopflo flow, so COD, RTO logic, and analytics stay intact.

Payment methods

UPI, card, and Cash on Delivery through your existing checkout. No new gateway to set up.

Nothing moves off the tools you already use. We build the connections around them, and Shopify remains your single dashboard.

How replies get routed

Every message passes through a router before it reaches a model. The router does not always pick the same model, it picks the right one for that message, right now.

Price

Cheapest model that can do the job

Routine replies go to the lowest-cost model. Only genuinely complex turns escalate to a stronger, pricier model.

Status

Live provider health

If a provider is rate-limited or briefly down, the router shifts that message to a backup provider automatically. Customers never see an error.

Latency

Fastest response available

If the usual model is running slow at that moment, the router picks whichever healthy option replies quickest.

This is what keeps the running cost estimates below near the low end even as your language mix broadens. It also means one provider having a bad day never takes the agent offline.

Your monthly running cost

Why this replaces a subscription platform like Wati. Platforms like Wati, AiSensy, and Interakt charge a monthly seat fee, typically ₹2,000 to ₹6,000 depending on tier, plus a markup on top of Meta's own message rates, commonly reported in the range of 15% to 30% over Meta's published pricing. That is paid every month, indefinitely, for a shared inbox and a rules-based chatbot, not a system that reads your catalogue, closes an order in the customer's own language, and routes a medical question to your doctors on its own. With this build, you own the system after year one, pay each provider directly at cost, and the recurring spend from year two is only the retainer, if you keep one, plus the running cost above.

What we need from you

Shopify access to read products, orders, and customers, and to create checkout links.

WhatsApp and Meta admin access for your number, plus Meta Business verification (we assist).

A WhatsApp chat history export, to train the agent on your tone and your customers' common questions.

Product notes and policies (usage, ingredients, offers) not already published on your site.

Appointment booking access and your two doctors' routing rules, matching how you use labels today.

A point of contact available during the 7-day build for quick questions and review.

Figures on this page are a planning estimate to support your decision, not a metered invoice. Language coverage: Gemini handles text across all major Indian languages and code-mixed speech such as Manglish. Sarvam's Speech to Text covers 22 Indian languages, and its Text to Speech covers the most widely spoken regional languages, which already includes Malayalam. Cost assumptions: an average of 800 input and 150 output tokens for a routine reply, 900 input and 250 output tokens for the roughly 15% of turns escalated to the stronger model, a 25 second average voice note, a 350 character average spoken reply, and one WhatsApp template sent for roughly one in five conversations under normal use, higher when the growth bundle is active. Currency conversion for Google's dollar-denominated rates uses approximately ₹95 per US dollar. Sarvam and Meta bill in Indian Rupees directly, so no conversion applies there. Meta's exact per-template rate can vary slightly by category and time of year, confirm the live rate card at billing time. AI usage and WhatsApp messaging costs are billed to your own accounts at cost, kept low by design.
