WhatsApp is the front desk of Indian small business, and Meta's pricing changes on 1 July 2025 made "WhatsApp Business API cost" a permanent top search. The short version: if you use the free WhatsApp Business app, nothing changed. If you use the API through a provider (Interakt, Wati, AiSensy, Gupshup, Zoho…), you now pay per message delivered, by category.
The 2026 price sheet for India (approximate)
| Message category | Price per message | When it's free |
|---|---|---|
| Service (replies to customers) | Free | Always, within the 24-hour customer-service window |
| Utility (order updates, invoices, OTP-style alerts) | ≈ ₹0.10–0.12 | Free when sent inside an open 24-hour window |
| Authentication (OTPs) | ≈ ₹0.10 | — |
| Marketing (offers, promos, re-engagement) | ≈ ₹0.78–0.88 | Never |
Prices are set by Meta and vary slightly by provider mark-up; volume tiers reduce them. GST at 18% applies.
Where the money leaks
- Templates mis-categorised as marketing. "Your order is ready — also check our new arrivals!" is marketing, at 8× the utility price. Keep utility templates purely transactional.
- Sending utility messages outside the 24-hour window. A "payment received" message 26 hours after the customer last wrote to you is billed; the same message at hour 23 is free. Reply promptly.
- Blast campaigns to cold lists. 5,000 marketing messages ≈ ₹4,400. Fine if it converts; expensive if it's a weekly habit. Meta also throttles marketing to users who ignore messages.
- Provider platform fees on top of Meta's rates — ₹1,000–5,000/month is typical. Compare before renewing.
How to run near-zero WhatsApp costs
Use click-to-chat links and QR codes for inbound
Every conversation the customer starts opens a free 24-hour window. Put a wa.me link with a pre-filled message on your website, Instagram bio, packaging and counter. Generate one with the WhatsApp direct chat tool — customers don't need to save your number.
Answer within the window
Set expectations ("we reply within 2 hours, 10am–8pm") and use quick replies. Every reply inside the window is free.
Send invoices and receipts as PDFs in the same window
When a customer orders on chat, send the payment receipt or invoice PDF in that conversation. Free, and it reads as service.
Ask for reviews inside the window
A review request right after a purchase is a service message. The Google review request builder writes a polite one with your review link.
Keep marketing to opted-in, engaged customers
Segment by last purchase (30/90 days). A marketing message to someone who bought last week converts 5–10×; to a 6-month-old lead it mostly gets you blocked. DPDP also requires explicit opt-in for marketing — see the DPDP checklist.
Use broadcast lists in the free app for micro-lists
The free WhatsApp Business app allows broadcast lists of 256 saved contacts who have your number saved. For a neighbourhood store, that covers the regulars at zero cost.
App vs API: which do you need?
| WhatsApp Business app | WhatsApp Business API | |
|---|---|---|
| Cost | Free | Per message + provider fee |
| Users | 1 phone (multi-device up to 4 linked) | Unlimited agents |
| Automation | Away messages, quick replies, catalogue | Chatbots, CRM integration, templates |
| Green tick | Rare | Available with verification |
| Best for | Shops, clinics, freelancers | Brands doing 1,000+ chats a month |
Most businesses under ₹5 crore are better served by the free app plus disciplined use of links and QR codes.
FAQ
Are replies to customers really free on the API?
Yes — any message you send within 24 hours of the customer's last message is a free service message, regardless of content, except template messages categorised as marketing.
Can I send a promo as a "utility" template to save money?
Meta reviews templates and reclassifies them; repeated misuse gets templates rejected and can get the number restricted.
Does the free app have any per-message charge?
No. It is free to use; you pay only for your data plan.
How much does a green tick cost?
Meta Verified for Business is a paid subscription (from roughly ₹600–1,000/month); the legacy Official Business Account badge is free but granted selectively to notable brands.
