WhatsApp API Cost for Ecommerce in India (2026)

What counts as free vs paid for ecommerce

The 24-hour service window is where a lot of ecommerce conversations should live, and it is frequently misunderstood. When a shopper messages your store first — replying to a shipping update, asking about a size, clicking a 'chat with us' button — you get a 24-hour window in which you can send free-form replies without sending a paid template each time. That window is a service convenience, not a billing unit; it does not turn subsequent template sends free, but it does mean a support agent answering three questions in a row is handling one conversation's worth of free-form messages, not three paid ones. The practical takeaway: reactive support and post-purchase Q&A are cheap, while proactive outbound (broadcasts and reminders that open a new template send) is where your controllable spend concentrates.

A worked monthly example for a growing store

Picture a mid-size D2C store doing a few thousand orders a month. It sends a utility 'order confirmed' and 'shipped' message on nearly every order, a checkout OTP on a share of them, and a couple of marketing broadcasts to its opted-in list each month. Because utility and authentication messages dominate the volume but sit at the low end of the rate card, the effective blended cost per message lands far below the headline marketing rate — most stores are surprised how little the transactional backbone costs. The expensive line is the marketing broadcast to the full list, which is exactly the message you should target rather than blast. Model your own split of utility vs marketing volume rather than multiplying total sends by the marketing rate; a naive 'price × total messages' estimate typically overstates the bill by a wide margin. The interactive calculator on our pricing tools lets you set your category mix and monthly volume to see the ₹ figure on Meta's rate plus your InfiQ plan, with a GST toggle.

• Transactional core (order + shipping + OTP): high volume, low per-message rate → small share of spend
• Marketing broadcasts: low volume, high per-message rate → the line to optimise
• Blended cost per message usually far below the marketing rate for a healthy transactional-heavy mix

5 ways ecommerce brands overpay (and the fix)

Most WhatsApp overspend in ecommerce is self-inflicted and fixable without touching your product catalogue. The biggest lever is category discipline: a transactional message sent under a marketing template pays the marketing rate for no reason. After that, it is about respecting the service window, protecting your quality rating, and targeting broadcasts instead of blasting the whole list. Fixing these usually cuts the bill more than switching providers ever could.

• Sending transactional alerts as marketing — recategorise order and shipping updates as utility templates
• Opening a fresh template send when you could reply inside the customer's 24-hour service window
• Over-messaging your list — high frequency raises cost and drags down your quality rating (which can throttle sends)
• Broadcasting to the entire opted-in base — segment to likely responders (recent buyers, cart-abandoners, browsers)
• Not tracking category mix — without a breakdown you cannot see which spend is discretionary vs essential

What InfiQ's pricing adds on top

On top of Meta's usage charge, InfiQ's monthly plan covers the platform work that makes WhatsApp usable for a store at scale: template creation and approval management, broadcast and automation tools, catalog and order-flow messaging, team inbox, and analytics that break spend down by category so you can act on the numbers above. Plans start at ₹999/month (ex-GST); GST at 18% applies on the platform fee. As an official Meta Business Partner, InfiQ handles Business verification and gives you full ownership of your WhatsApp Business Account — and as Meta rolls out BSUID (Business-Scoped User IDs) with the 2026 WhatsApp usernames change, your account and contact identity stay with you. Pricing is presented as transparent ₹ pass-through so you always see what is Meta's charge and what is the platform fee.
