Most blogs answering "is WATI or AiSensy cheaper for Indian SMBs" were written before the Meta India 1 January 2026 conversation-rate revision, before the November 2024 draft DPDP Rules, and before the INR drifted past 84 against the USD. The pricing math is stale and the compliance posture is incomplete. This piece is the corrective: WATI vs AiSensy modelled at three real SMB volume tiers (500, 2,000 and 5,000 marketing conversations per month) with Meta pass-through, 18% GST and FX exposure all included — plus a candid note on the one scenario where neither is the right answer.
The three numbers that decide this
Every honest answer to "which is cheaper" lives in three numbers, not one:
- Monthly platform fee. AiSensy Basic INR 999 versus WATI Growth USD 49 (about INR 4,116 at June 2026 reference rate of INR 84/USD).
- Per-conversation pass-through to Meta. Both BSPs pass through the Meta WhatsApp Business Platform conversation rate — approximately INR 0.78 per marketing conversation in India after the 1 January 2026 revision.
- GST at 18%. India-billed services attract straightforward GST input credit; USD-billed services trigger the reverse-charge mechanism, which is mechanically the same on paper but adds reconciliation friction every quarter.
The headline price is the smallest piece. The full bill is platform fee plus Meta pass-through plus GST — and for USD-billed platforms, plus FX risk.
WATI vs AiSensy TCO at 500, 2,000 and 5,000 conversations/month
500 marketing conversations per month
| Cost line | RichAutomate | AiSensy Basic | WATI Growth |
|---|---|---|---|
| Platform fee (INR) | 0 | 999 | 4,116 (USD 49) |
| Meta pass-through (500 x INR 0.78) | 390 | 390 | 390 |
| Platform markup per conv | 50 (INR 0.10 x 500) | 0 (bundled) | 0 (bundled) |
| Subtotal pre-GST | 440 | 1,389 | 4,506 |
| GST 18% | 79 | 250 | 811 |
| Total INR/month | 519 | 1,639 | 5,317 |
Verdict at 500 conv/mo: RichAutomate is roughly 68% cheaper than AiSensy Basic and 90% cheaper than WATI Growth. Among the two named in the search query, AiSensy is the clear winner over WATI.
2,000 marketing conversations per month
| Cost line | RichAutomate | AiSensy Basic | WATI Growth |
|---|---|---|---|
| Platform fee (INR) | 0 | 999 | 4,116 |
| Meta pass-through (2,000 x INR 0.78) | 1,560 | 1,560 | 1,560 |
| Platform markup per conv | 200 | 0 | 0 |
| Subtotal pre-GST | 1,760 | 2,559 | 5,676 |
| GST 18% | 317 | 460 | 1,022 |
| Total INR/month | 2,077 | 3,019 | 6,698 |
Verdict at 2,000 conv/mo: AiSensy is approximately 55% cheaper than WATI. RichAutomate is 31% cheaper than AiSensy. The gap between WATI and AiSensy widens as a percentage at higher utility/authentication mix because the platform fee is fixed but pass-through scales linearly.
5,000 marketing conversations per month + 1,000 utility
At this volume most SMBs migrate up tiers. AiSensy Basic users typically move to AiSensy Pro at INR 2,399/month; WATI users stay on Growth or move to Pro at USD 99/month.
| Cost line | RichAutomate | AiSensy Pro | WATI Pro |
|---|---|---|---|
| Platform fee (INR) | 0 | 2,399 | 8,316 (USD 99) |
| Marketing pass-through (5,000 x INR 0.78) | 3,900 | 3,900 | 3,900 |
| Utility pass-through (1,000 x INR 0.115) | 115 | 115 | 115 |
| Platform markup (6,000 x INR 0.10) | 600 | 0 | 0 |
| Subtotal pre-GST | 4,615 | 6,414 | 12,331 |
| GST 18% | 831 | 1,154 | 2,220 |
| Total INR/month | 5,446 | 7,568 | 14,551 |
Verdict at 5,000+1,000 conv/mo: AiSensy Pro is roughly 48% cheaper than WATI Pro. RichAutomate is 28% cheaper than AiSensy Pro. The WATI gap holds across tiers.
Why WATI looks competitive in their own marketing but isn't at SMB scale
WATI's marketing site emphasises feature depth (multi-agent inbox, no-code template marketplace, polished English UI) rather than price. Those features are real. The pricing reality for Indian SMBs is that USD billing introduces three structural disadvantages that no feature delta erases at 500 to 5,000 conversations per month:
- FX exposure. If the INR weakens from 84 to 88 against the USD over 12 months — well within the historical band — your WATI subscription silently re-prices upward by about 4.8%. AiSensy is INR-priced and INR-billed.
- Reverse-charge GST. India-billed AiSensy issues a regular GST invoice; your CA reconciles it on autopilot. USD-billed WATI triggers the reverse-charge mechanism — legally clean but every quarter your CA spends time on it, which is a small but real recurring tax.
- Hong Kong support latency. WATI is Hong Kong-headquartered (Clare.ai). The IST support coverage exists but is thinner than India-headquartered AiSensy. For SMBs running 9am-9pm India support shifts on WhatsApp, this matters.

Verdict by SMB persona
D2C brand (1 to 3 agents, 2k-5k campaigns/mo) AiSensy or RichAutomate
You need a predictable monthly bill, broadcast UI for festival campaigns, and clean GST input credit. WATI is hard to justify. AiSensy Basic-to-Pro is the cheapest fixed-tier path; RichAutomate is cheaper still if you are comfortable with usage-only billing. See the D2C use case.
Local retail (1 agent, under 1k conv/mo) RichAutomate
At under 1,000 conversations per month, paying INR 999 or USD 49 just for the platform is a tax on small volume. RichAutomate's INR 0 monthly fee with usage-only billing is the right answer — even AiSensy Basic looks expensive at this scale. WATI is not in contention. Restaurants and salons should also read the restaurants pillar.
Services business (3 to 5 agents, 2k-3k conv/mo) AiSensy
Mixed marketing + utility messages with light automation. AiSensy Basic-to-Pro is the sweet spot if you want a single recognised India brand for procurement. WATI's price premium does not buy materially more at this scale.
India SMB with overseas customers WATI
This is the one scenario where WATI is defensible over AiSensy. If 30%+ of your conversations are with overseas customers and you want a single vendor with strong English-first support and an international UI, the WATI premium can be worth it. Otherwise stay India-billed.
Compliance posture: WATI vs AiSensy under DPDP Act 2023
Cost is one axis. The other is your exposure under the Digital Personal Data Protection Act 2023 and the November 2024 draft DPDP Rules from the Ministry of Electronics and Information Technology. Both AiSensy and WATI handle DPDP largely at the contract layer through Data Processing Agreements. Neither ships a deep admin-facing in-app toolkit (consent flows, configurable retention, one-tap deletion, privacy policy generator) as of June 2026. Under the draft Rules, in-app tenant tooling materially reduces audit burden — making this a meaningful tie-breaker for regulated SMBs.

| Compliance axis | AiSensy | WATI | RichAutomate |
|---|---|---|---|
| DPDP Act 2023 DPA | Yes (signed) | Yes (signed) | Yes (signed) |
| In-app consent flows | Partial | Contract-layer | Full toolkit |
| Configurable retention (data minimisation) | No | No | Yes (default 90d) |
| One-tap data-subject delete | No | No | Yes |
| Privacy policy generator | No | No | Yes |
| Billing currency | INR | USD | INR |
| HQ | Gurugram | Hong Kong | India |
| WABA timeline (typical onboarding) | 24-48 hrs | 24-72 hrs | 24-48 hrs |
How to actually run this comparison on your own numbers
The tables above use modelled assumptions. The cleanest way to validate them against your real spend is a 5-step exercise:
- Pull the last 90 days of conversation volume from your current vendor or estimate from your CRM. Split into marketing, utility and authentication categories.
- Multiply each category by the Meta rate for India as of 1 January 2026 (marketing INR 0.78, utility INR 0.115, authentication INR 0.115 — verify against the latest Meta pricing page).
- Add the platform fee for each vendor at the tier matching your volume and agent count.
- Apply 18% GST on the platform-fee line and the markup line; pass-through GST treatment varies by vendor invoice structure.
- Compare three scenarios: base case, volume up 50%, volume down 30%. The right vendor is the one that does not punish you in any of the three.

Migration is not the risk you think it is
The single biggest blocker to switching from WATI to AiSensy — or from either to RichAutomate — is fear of losing the WhatsApp number, the blue tick, or the approved templates. None of those are at risk in a properly executed migration. Your WhatsApp Business Account (WABA) and phone number are owned by you on the Meta side, not by the BSP. A BSP-change request is a Meta-side operation that typically completes in 24 to 72 hours with zero downtime. Blue tick, approved templates, business profile and message-history references all carry over. See our migration runbook and the green-tick verification guide.
What to do next
If you are choosing between WATI and AiSensy for an Indian SMB workload, the answer is almost always AiSensy on cost grounds — unless you genuinely need a global vendor. The deeper question is whether a usage-only model like RichAutomate fits better than either fixed-tier option.
