India does business on WhatsApp — half a billion users, open rates north of 90%, and a generation of customers for whom 'website' means 'WhatsApp karo'. The platform now offers a genuine commerce stack: catalogues, payments, automation, APIs — and two very different products (the free Business app versus the API) that businesses routinely confuse. Here is the complete map: which tier you need, the rules that keep you unblocked, and the selling playbook.
Business App vs API: choose your tier
- WhatsApp Business App (free): one number, up to a few linked devices, catalogues, labels, quick replies, basic broadcast lists (256/list, recipients must save your number) — right for micro businesses and single-operator selling
- WhatsApp Business API/Platform (via BSPs — Meta partners like Interakt, Wati, AiSensy, Gupshup): unlimited scale broadcasts to opted-in users, chatbots and automation flows, multi-agent shared inboxes, CRM/webhook integrations, verified green-tick eligibility — the tier for serious volume (typically ₹1,000–5,000/month platform fees plus Meta's per-conversation charges)
- The graduation trigger: when broadcast reach, team inboxes or automation matter — usually at 300+ customer conversations monthly
The commerce stack in practice
Catalogues: products with photos, prices and descriptions living inside the chat — the storefront customers browse without leaving the conversation; keep it current (stale catalogues kill trust faster than no catalogue). Carts and orders: customers assemble carts from catalogues; your flow confirms, collects address, and closes. Payments: UPI-powered WhatsApp payments and payment-link integration (Razorpay/PhonePe links in-chat) — the friction-free close. The API layer adds: automated order confirmations and shipping updates (the notifications customers actually want), abandoned-cart nudges, reorder journeys for consumables ('pichhla order repeat karein?' — D2C India's highest-ROI message), and click-to-WhatsApp ads (Meta ads opening chats instead of landing pages — for many Indian SMEs, the highest-converting ad format that exists).
WhatsApp's ecosystem runs on consent and quality: broadcasts via API require opt-ins (documented — checkout checkboxes, keyword opt-ins, ad-click consents); template messages (anything business-initiated outside the 24-hour service window) need Meta approval and carry per-message pricing (marketing templates costlier than utility); quality ratings drop with blocks/reports — and dropped ratings throttle your reach; the Business-app shortcut of spamming saved-number lists gets numbers banned weekly. The discipline: segment tightly, message 2–6 times monthly maximum for marketing, always include opt-out, and front-load value (offers, restock alerts customers wanted) — the list you don't exhaust is the asset.
Automation flows worth building first
- The greeting + menu bot: instant response with numbered options (catalogue, order status, talk to human) — 24×7 first-touch at zero marginal cost
- Order lifecycle: confirmation → payment link → shipping updates → delivery confirmation → review ask (the utility sequence customers rate positively)
- Lead qualification: service businesses' intake flows (requirement, budget, location questions) delivering qualified summaries to your team
- Reorder/replenishment: consumables timed to consumption cycles — subscription economics without subscription friction
- The human handoff rule: every flow escapes to a person on request; automation that traps customers generates the blocks that kill your rating
The measurement loop
Treat WhatsApp as a channel with a P&L: list growth (opt-ins weekly, by source), broadcast performance (delivered/read/replied/converted per campaign — read rates under 70% signal list fatigue or quality problems), conversation-to-order conversion by flow, template costs against revenue per campaign, and the service metrics (first-response time, resolution rates) that quality ratings reflect. The strategic posture: WhatsApp is your retention and conversion engine — acquisition still comes from ads, marketplaces and local search; the businesses winning on WhatsApp use it to make every acquired customer worth 2–3× more, which is exactly the economics acquisition channels can't give you.
