If you've decided your business needs the WhatsApp Business API, your shortlist almost certainly reads Wati, Interakt, AiSensy — the three names every Indian founder hears first. They look similar on the surface: all three sit on the same official Meta API, all three send the same green-tick messages, all three run campaigns.
We're an automation company from Pune, not a BSP — we integrate with these tools rather than compete head-on with their inbox. That makes us usefully neutral: here's how the three actually differ, where each one wins, and the question almost nobody asks before paying — do you need a WhatsApp tool at all, or an automation platform?
First, what's identical in all three
- The pipe. Same official WhatsApp Business API underneath. Delivery, green tick eligibility, template approval rules — Meta's, not theirs.
- Meta's per-message fees. Utility, marketing and authentication conversation rates are set by Meta and billed per message on top of any subscription. No tool escapes them.
- Template discipline. Outside the 24-hour service window, everyone sends pre-approved templates. A tool can make submission easier; it cannot bend the rule.
So you are really choosing the software around the pipe: inbox, campaign manager, chatbot builder, integrations, and price.
Where each one genuinely wins
Wati — the mature team inbox
Wati's strength is the shared inbox experience at team scale: agent assignment, labels, canned replies, a polished no-code chatbot builder, and a big template/integration ecosystem. It's the most "finished" product of the three — and typically the most expensive, with per-agent pricing that adds up as the team grows. If you run a support/sales team living inside WhatsApp all day, Wati earns its price.
Interakt — the value pick with commerce leanings
Interakt (from Haptik/Jio family) undercuts on entry price and does commerce plumbing well — catalog messages, ads-that-click-to-WhatsApp flows, Shopify plugins. The inbox is functional rather than fancy. For a D2C brand that wants official API + campaigns without a heavy subscription, Interakt is usually the budget-sensible shortlist winner.
AiSensy — campaign-first and friendly to small budgets
AiSensy grew on broadcast/campaign use cases: bulk template sends to opted-in lists, click-to-WhatsApp ad journeys, and a pricing approach that historically let small businesses start very cheap. The campaign manager is the heart of the product; the inbox is serviceable. If your primary use is send approved campaigns to my list and track replies, AiSensy is hard to beat on value — and it's the account Yantra can plug into directly (more below).
The comparison table
| Wati | Interakt | AiSensy | Yantra (context) | |
|---|---|---|---|---|
| What it is | WhatsApp inbox + chatbot suite | WhatsApp API + commerce tools | WhatsApp campaign platform | Cross-app automation platform |
| Team inbox | Best of the three | Functional | Serviceable | Basic (2-way needs your Meta number) |
| Campaigns / broadcast | Yes | Yes | Core strength | Yes — as flow steps with quotas |
| Chatbot builder | Strong, no-code | Basic flows | Basic flows | Full flow builder (any app, not just chat) |
| Beyond WhatsApp | Limited (CRM-ish) | Commerce plugins | Ads + catalog | Razorpay, Tally, GST invoices, Sheets, Shopify, approvals… |
| Typical cost shape | Higher sub + per agent | Lower sub | Low entry, pay for scale | Free 1,000 runs, then plan — pricing |
| Best for | Support/sales teams in chat all day | D2C on a budget | List campaigns & small biz | Multi-app processes that include WhatsApp |
The question nobody asks: tool ya automation?
Here's the miss we see weekly. A distributor wants this: payment aaya Razorpay pe → Tally mein entry → customer ko WhatsApp receipt → 3 din baad pending balance reminder. He buys a WhatsApp tool… and discovers he bought a very good inbox. The WhatsApp message is step three of a four-step process, and steps one, two and four live in Razorpay, Tally and a calendar — places no BSP tool reaches.
That's the split:
- Buy a BSP tool (Wati/Interakt/AiSensy) when the conversation is the product — team inbox, campaigns, chat commerce.
- Buy an automation platform when WhatsApp is one step in a chain — payment reminders, Tally entries, GST invoices, approval flows.
- Often the answer is both, and they work together: keep AiSensy for campaigns and live chat, and let Yantra drive the process messages through your AiSensy account — our connector sends approved templates via the campaign API, no Meta setup needed on your side. One number, two jobs.
And to be honest the other way: if all you want is an inbox for five agents, don't buy an automation platform. You'd be paying for machinery you won't switch on. (The same honesty test we applied to Zapier and Pabbly applies to us.)
Decision shortcuts
- Support team of 3+ living in WhatsApp all day → Wati (budget tight? Interakt).
- D2C brand, campaigns + Shopify, watching every rupee → Interakt or AiSensy.
- Opted-in list + weekly offers, smallest possible start → AiSensy.
- "Jab payment aaye / order aaye / lead aaye to ye 4 kaam apne aap ho" → that's an automation platform; start with the WhatsApp automation playbook and keep whichever BSP you like for chat.
