Understanding WhatsApp Business API pricing helps Indian businesses budget for notifications, support, and marketing at scale. Costs come from two layers: Meta's per-message charges and your platform provider (SMSTAKE).
How Meta Charges: Per Delivered Message
Since 1 July 2025, Meta has billed the WhatsApp Business Platform per message, replacing the earlier conversation-based model. A charge applies when a template message is delivered to the customer, not when it is sent, and messages customers send to your business are not charged. From 1 October 2026, service messages are also charged per delivered message (see below).
The rate for each message depends on its category and the recipient's market - the country calling code of their WhatsApp number. Meta publishes rate cards, may update them up to once a quarter, and offers volume tiers for utility and authentication messages. For current rates in India and other markets, see Meta's official WhatsApp Business Platform pricing page.
Message Categories
- Marketing - template messages for promotions, offers, product announcements, and re-engagement. Every delivered marketing template is charged.
- Utility - template messages linked to a specific transaction or account, such as order confirmations, shipping updates, and payment alerts.
- Authentication - template messages that carry one-time passcodes for login or verification. Some markets, including India, also have an authentication-international rate that can apply to eligible businesses.
- Service - free-form (non-template) replies, which can only be sent inside an open customer service window, whether written by an agent or sent by a chatbot.
Marketing, utility, and authentication are template categories. Meta reviews each template and may assign or update its category, so check the category on every approved template - the charge follows the category applied to a template at the time it is sent.
Changes from 1 October 2026
Meta has announced two billing changes that take effect on 1 October 2026:
- Service messages become chargeable per delivered message, at the same rate as utility and authentication messages in each market. Each business phone number receives 1,000 free service messages per month, and charges start from the 1,001st.
- Utility templates sent inside an open customer service window become chargeable. These have been free since 1 July 2025.
Free entry point windows still apply. If a customer messages you from a Click-to-WhatsApp ad using WhatsApp's Android or iOS app, and you reply within the 24-hour customer service window, a free entry point window opens from the time of your reply. It can stay open for up to 7 days, and every message you send while it is open is free.
The 24-Hour Customer Service Window
The customer service window controls what you can send, not how you are billed. It opens when a customer messages your business and resets each time they send a new message. While it is open, you can reply with free-form messages; after it closes, you can only reach that customer with an approved template message. Charges are calculated per delivered message according to the category rules above, so fitting more messages into one window does not reduce your cost.
SMSTAKE Platform Plans
SMSTAKE offers flexible plans for startups, growing businesses, and enterprises. Contact our sales team for a quote based on your volume and channels.
Meta's per-message charges are separate from SMSTAKE plan pricing and depend on the messages you deliver.
Cost-Saving Tips
- Use the right template category - transactional updates belong in utility, which is usually priced lower than marketing in the same market
- Send marketing templates to opted-in customers who are likely to engage, because every delivered marketing message is charged
- Combine SMS for OTP when WhatsApp authentication costs more for your audience
- Use chatbots and quick replies to resolve support queries in fewer messages, since service messages beyond the monthly free allowance are charged from 1 October 2026
- Track delivered messages by category and market to forecast spend and see when volume tiers apply
