WhatsApp Business API pricing in India has two layers: what Meta charges per conversation, and what your BSP (Business Solution Provider) charges on top. As of the 1 January 2026 rate revision, Meta charges roughly ₹0.8631 per marketing conversation and ₹0.115 per utility/authentication conversation (a ~10% hike — verify current rates on Meta's rate card), while BSP platform fees range from ₹0/month with RichAutomate to ₹16,000+/month on enterprise tiers of other vendors.
This page breaks down the full cost table so you can estimate a realistic monthly bill for 1,000, 10,000, or 50,000 conversations — including 18% GST and the hidden costs most pricing pages skip.
How WhatsApp API pricing works: the two-layer model
Every rupee you spend on the WhatsApp Business API splits into two invoices:
- Layer 1 — Meta conversation charges. Billed by Meta per conversation (a 24-hour messaging window), not per message. Priced by category.
- Layer 2 — BSP platform fee. Your provider (RichAutomate, Wati, AiSensy, Interakt, Gupshup, etc.) charges for the software: inbox, broadcast, chatbot builder, API access, and support. This is a monthly subscription, a per-message markup, or both.
Confusion almost always comes from mixing these two. A "₹999/month" plan you see advertised is only Layer 2 — you still pay Meta separately for Layer 1 unless the plan explicitly bundles conversation costs.
Meta's per-conversation categories (2026)
Since the pricing model shifted, Meta bills by conversation category rather than a flat rate. India rates after the 1 January 2026 revision (verify against Meta's live rate card, as rates change):
| Conversation category | What it covers | Meta rate (India, 2026) |
|---|---|---|
| Marketing | Promotions, offers, product launches, re-engagement | ~₹0.8631 |
| Utility | Order updates, payment reminders, appointment alerts | ~₹0.115 |
| Authentication | OTPs and login verification codes | ~₹0.115 |
| Service | Customer-initiated support replies within the free window | Free (unlimited) |
Two things move your Meta bill down: service conversations are free (customer-initiated support inside the 24-hour window costs nothing), and utility conversations inside an open service window can also be free under the current entry-point rules. The expensive category is marketing — that is where volume discipline matters most.
The BSP platform-fee layer: ₹0 to ₹16,000+/month
This is where providers differ wildly. Some charge a fixed monthly subscription regardless of usage; some add a per-message markup; some do both. RichAutomate charges ₹0 platform fee, ₹0 setup fee, and ₹0 monthly fee — you pay only for what you send.
| Provider | Platform / monthly fee | Per-message markup | Meta charges |
|---|---|---|---|
| RichAutomate — Client Pay | ₹0/mo | ₹0.10/msg | Billed to you direct by Meta |
| RichAutomate — SaaS Pay | ₹0/mo | ₹1.20 marketing / ₹0.30 utility (all-inclusive) | Bundled — no separate Meta bill |
| Wati | ~₹2,499+/mo (verify vendor site 2026) | Varies by plan (verify) | Usually separate (verify) |
| AiSensy | ~₹999–₹3,000+/mo (verify vendor site 2026) | Plan-dependent (verify) | Usually separate (verify) |
| Interakt | ~₹2,499+/mo (verify vendor site 2026) | Plan-dependent (verify) | Usually separate (verify) |
| Gupshup | Varies; enterprise tiers ₹16,000+/mo (verify vendor site 2026) | Per-message model (verify) | Usually separate (verify) |
Competitor figures above are directional and change often — always confirm on the vendor's own 2026 pricing page before budgeting. The structural point stands: most BSPs gate features behind a monthly subscription that you pay even in a slow month, while RichAutomate's ₹0-monthly model means a dormant month costs you nothing.

Client Pay vs SaaS Pay — which RichAutomate model?
- Client Pay (bring your own Meta billing): ₹0/month + ₹0.10 per message, and Meta bills your own credit card directly at cost. Cheapest at scale — you pay Meta's raw ₹0.8631/₹0.115 with only a ₹0.10 software markup on top.
- SaaS Pay (all-inclusive): ₹1.20 per marketing message, ₹0.30 per utility message — Meta cost is bundled in, so there is no separate Meta invoice and no card setup with Meta. Simplest for businesses that want one predictable bill or don't yet have Meta billing configured.
Worked monthly examples (incl 18% GST)
Below are realistic all-in monthly estimates assuming marketing conversations (the priciest category). We treat one conversation ≈ one outbound message for estimation; your real mix of marketing vs utility vs free service conversations will lower the effective cost. GST at 18% applies to the Indian BSP invoice.
RichAutomate Client Pay (₹0/mo + ₹0.10/msg + Meta direct)
| Monthly volume | Meta charge | Platform fee (+18% GST) | All-in / month |
|---|---|---|---|
| 1,000 marketing | ₹863 | ₹100 → ₹118 | ≈ ₹981 |
| 10,000 marketing | ₹8,631 | ₹1,000 → ₹1,180 | ≈ ₹9,811 |
| 50,000 marketing | ₹43,155 | ₹5,000 → ₹5,900 | ≈ ₹49,055 |
RichAutomate SaaS Pay (all-inclusive, ₹1.20/marketing)
| Monthly volume | Base (₹1.20/msg) | +18% GST | All-in / month |
|---|---|---|---|
| 1,000 marketing | ₹1,200 | ₹216 | ₹1,416 |
| 10,000 marketing | ₹12,000 | ₹2,160 | ₹14,160 |
| 50,000 marketing | ₹60,000 | ₹10,800 | ₹70,800 |
The takeaway: Client Pay is dramatically cheaper at volume because you pay Meta at cost, while SaaS Pay trades a higher per-message rate for zero billing setup and one clean invoice. A utility-heavy business (OTPs, order updates) pays far less than these marketing figures — utility runs ₹0.30/msg on SaaS Pay and ₹0.115 + ₹0.10 on Client Pay. If you moved half your marketing to utility templates, both columns roughly halve.
Hidden costs to watch
The sticker rate is never the full story. Budget for these before you commit:
- Monthly minimums and seat fees. Some BSPs bill per agent seat or enforce a plan floor. RichAutomate has none — ₹0 seats, ₹0 minimum.
- Setup and onboarding fees. One-time charges for WABA setup or "green tick" assistance appear on some vendors' invoices (verify). RichAutomate setup is ₹0.
- Conversation category creep. A "utility" template Meta re-classifies as marketing costs ~7.5x more. Template wording and category matter — a good BSP flags this before you send.
- Failed / undelivered messages. You still incur costs on some send attempts. Clean lists and opt-in hygiene protect the bill.
- GST. The 18% GST above applies to the Indian software invoice and is claimable as input credit if you're GST-registered. Note: to take your WABA live in India, GST registration is effectively required — a trial can run without it, but production cannot.
- Compliance risk, not "no ban". Aggressive or non-opted-in bulk marketing carries a real WABA ban risk. No provider can promise immunity — spend is wasted if your number is restricted. Send to opted-in contacts with approved templates.
Free trial: test before you spend
RichAutomate includes a 14-day free trial plus 100 free message credits, with no platform, setup, or monthly fee to cancel. That's enough to connect your WABA, approve a template, run a small broadcast, and see your true per-conversation cost on real traffic before committing a rupee. Because there's no monthly subscription, there's nothing to "downgrade" if a month is slow.

Bottom line
For most Indian businesses in 2026, the real WhatsApp API bill is Meta's ₹0.8631 marketing / ₹0.115 utility per conversation plus a BSP fee — and that BSP fee is exactly where you control cost. Paying ₹2,499–₹16,000+/month in fixed subscriptions (verify each vendor) buys convenience but bleeds in slow months; RichAutomate's ₹0-monthly, pay-per-use model means your platform cost tracks your actual usage, and Client Pay keeps you at Meta's raw rate with a ₹0.10 markup. Run the free trial, watch your category mix, and let the numbers pick the plan.
