WhatsApp Business API Cost in India — With GST Explained

How Meta bills each message category

Meta prices by intent, not by length, so a one-line reminder and a long detailed message in the same category cost the same. Marketing messages — promotions, offers, re-engagement — carry the highest rate. Utility messages — order confirmations, shipping updates, appointment reminders, payment receipts tied to a specific transaction — are far cheaper. Authentication messages, used for OTPs and login codes, sit in their own low-cost bucket. There is also a free service window: when a customer messages you first, you can reply for 24 hours at no per-message charge — ₹0 today (chargeable from 1 October 2026) — which is why support-heavy accounts often pay less than their raw volume suggests. The single biggest cost lever most Indian businesses miss is category discipline — sending a transactional alert as a marketing template pays the marketing rate for no reason.

A worked ₹ example with GST

Say a D2C brand sends 20,000 utility messages (order and delivery updates) and 5,000 marketing messages in a month. Using the current rates of ₹0.19 for utility and ₹0.94 for marketing: utility = 20,000 × ₹0.19 = ₹3,800; marketing = 5,000 × ₹0.94 = ₹4,700. Meta subtotal ≈ ₹8,500 ex-GST. Add an InfiQ plan of ₹999 → ex-GST subtotal ≈ ₹9,499. Apply 18% GST → ₹9,499 × 1.18 ≈ ₹11,209 payable. Notice how the marketing slice, at a quarter of the volume, is over half of the Meta charge — which is exactly why modelling your real category mix beats assuming a flat per-message price. Rerun the numbers with your own volumes before committing to a plan.

• Utility: 20,000 × ~₹0.19 ≈ ₹3,800
• Marketing: 5,000 × ~₹0.94 ≈ ₹4,700
• + InfiQ plan: ₹999 → ex-GST subtotal ≈ ₹9,499
• + 18% GST ≈ ₹11,209 payable (indicative)

Is the GST recoverable, and how does it show on the invoice

For a GST-registered business, the 18% GST charged on your WhatsApp API spend is generally available as input tax credit, provided the supply is used for business and the invoice carries your GSTIN and a valid tax invoice from the provider. In practice that means the sticker figure includes GST, but your effective cost is closer to the ex-GST subtotal once you claim credit. InfiQ issues a proper GST tax invoice showing the ex-GST message and platform charges separately from the GST line, so your finance team can reconcile Meta's message spend, the platform fee, and the tax cleanly. Always confirm eligibility with your accountant — ITC rules depend on your registration and usage, not on us.

Where businesses overpay — and how to fix it

Cost overruns on WhatsApp are almost always structural, not about the rate card. Recategorising eligible alerts from marketing to utility can cut the largest line item dramatically. Replying inside the free 24-hour service window instead of opening fresh billable sends trims support costs. Tight audience segmentation avoids paying to message people who never convert — and over-messaging also drags down your quality rating, which can throttle throughput. Finally, if you are on a provider that adds an opaque per-message uplift, moving to transparent ₹ pricing makes every future estimate predictable. Fix these four and the GST-inclusive total usually falls without sending a single fewer useful message.

• Recategorise transactional alerts from marketing to utility where eligible
• Reply in the free 24-hour service window instead of opening billable sends
• Segment audiences so you pay for messages likely to convert
• Choose transparent ₹ pricing over an opaque per-message uplift
