AiSensy, Interakt, Wati, and RichAutomate are four WhatsApp Business Solution Providers serving Indian D2C brands, fintechs, EdTechs, and marketing agencies in 2026. They are all Meta-authorized BSPs. They all route through the same Meta Cloud API. The per-message Meta charge is identical on every platform — ₹0.8631 for marketing, ₹0.115 for utility, ₹0.115 for authentication under the January 2026 India rates. The real difference is everything wrapped around that: platform subscription fees, per-message markup, billing model flexibility, Flow builder depth, team inbox behavior, and whether you are forced to hold a Meta credit card on day one. This guide is the 2026 India comparison the ranking listicles do not give you — real unit economics at 100k and 1M message volumes, feature-by-feature matrix, and the buyer decision framework based on what your business actually does.
The One Number Everyone Misses: Platform Subscription Floor
Every Indian BSP published price sheet highlights per-message rates. Almost none lead with the monthly subscription floor, which is the line item that actually decides whether a BSP is cheap or expensive for your volume. AiSensy starts at ₹1,500/month, Wati at ₹1,999/month (with their cheapest plan lacking a chatbot builder), Interakt at ₹2,499/month. RichAutomate has no subscription floor — ₹0 per month on Client Pay, with platform fee applied only on messages actually sent. For a small D2C brand sending 10,000 marketing messages per month, the subscription floor is often 80% of the total BSP spend. For a high-volume fintech sending 1M+ messages, the subscription barely registers. Pick the billing model that matches your volume, not the one with the fanciest dashboard.
2026 Comparison Matrix: AiSensy vs Interakt vs Wati vs RichAutomate
| Attribute | AiSensy | Interakt | Wati | RichAutomate |
|---|---|---|---|---|
| Starting monthly fee | ₹1,500 | ₹2,499 | ₹1,999 | ₹0 (usage-only) |
| Pro / mid-tier monthly | ₹3,200 | ₹3,499+ | ₹4,499 | ₹0 (no tiers) |
| Per-message Meta pass-through | Yes | Yes | Yes | Yes (Client Pay) |
| Platform markup per message | Low–medium | Medium | Medium | ₹0.10 flat (Client Pay) or inclusive |
| Meta credit card required | Yes (for direct Meta) | Yes | Yes | Optional — not required on SaaS Pay |
| Dual billing (Client Pay + SaaS Pay) | No | No | No | Yes |
| Visual chatbot builder | Included | Included | Entry plan limited | Included |
| Meta Native Flows support | Yes | Yes | Yes | Yes |
| Shared team inbox | Yes | Yes | Yes | Yes |
| Shopify integration | Yes | Deep native | Yes | Webhook-based |
| Developer API / webhooks | Limited | Standard | Standard | Full REST API + webhooks |
| White-label / multi-tenant | Enterprise tier | Limited | Limited | Built-in multi-tenant |
| Click-to-WhatsApp ad integration | Native | Native | Available | Available |
| Typical support channel | Calls, chat, email | Email-led | Email-led | WhatsApp, email |
Feature parity is high at the core. Almost every BSP exposes the same Meta Cloud API primitives. Differences emerge in pricing model, multi-tenant handling, and whether you are locked into one billing path.
Real Unit Economics at 100k and 1M Messages
Meta per-message rate is identical everywhere. The variable is BSP platform fee plus markup. Below: actual monthly cost for an Indian D2C brand sending marketing templates at 2026 India rates.
Scenario A: 100,000 Marketing Messages Per Month
| BSP | Meta charge | Platform subscription | BSP markup | Monthly total |
|---|---|---|---|---|
| AiSensy (Pro plan) | ₹86,310 | ₹3,200 | ~₹0 | ₹89,510 |
| Interakt (Growth plan) | ₹86,310 | ₹3,499 | ~₹0–₹10,000 | ₹89,809–₹99,809 |
| Wati (Standard) | ₹86,310 | ₹1,999 | ~₹0–₹8,000 | ₹88,309–₹96,309 |
| RichAutomate (Client Pay) | ₹86,310 | ₹0 | ₹10,000 (₹0.10/msg) | ₹96,310 |
| RichAutomate (SaaS Pay inclusive) | — | ₹0 | — | ₹1,20,000 (₹1.20 × 100k) |
At 100k marketing volume, Wati and AiSensy win on total cost on paper — but the Wati Standard plan lacks the chatbot builder and pushes you to ₹4,499 Pro (which closes the gap). RichAutomate's Client Pay flat ₹0.10 platform fee is higher at 100k but wins at scale. SaaS Pay inclusive is the priciest option at this volume and is meant for brands without a Meta credit card.
Scenario B: 1,000,000 Marketing Messages Per Month
| BSP | Meta charge | Platform subscription | BSP markup | Monthly total |
|---|---|---|---|---|
| AiSensy (Enterprise) | ₹8,63,100 | Custom | Varies | ₹9,00,000+ typical |
| Interakt (Growth+) | ₹8,63,100 | ₹3,499+ | ₹50,000–₹1,00,000 | ₹9,16,599–₹9,66,599 |
| Wati (Business) | ₹8,63,100 | ₹13,499 | ₹50,000–₹80,000 | ₹9,26,599–₹9,56,599 |
| RichAutomate (Client Pay) | ₹8,63,100 | ₹0 | ₹1,00,000 (₹0.10/msg) | ₹9,63,100 |
At 1M volume the subscription floors are irrelevant and per-message markup dominates. RichAutomate's flat ₹0.10 becomes predictable compared to percent-based BSP markups that creep. Negotiate all BSPs hard at this volume — most have volume discounts not published on their pricing page.
Who Each BSP Is Actually Built For
AiSensy — Best for Small-to-Mid D2C Running Paid Meta Ads
AiSensy's native Click-to-WhatsApp ad integration, AI template generator, and AI ad creative tool are positioned for D2C brands acquiring customers through Meta ads. The lowest starting price (₹1,500) suits brands sending 10k–100k messages per month. Weak spots: developer API is limited compared to Interakt, and multi-tenant white-label is behind the enterprise gate.
Interakt — Best for Shopify and E-commerce D2C
Interakt's deep Shopify integration, abandoned cart recovery flows, and e-commerce-specific template library make it the default pick for Shopify-native brands. Support is email-led which slows down incident response. Starting price (₹2,499) is higher than AiSensy but the Shopify depth typically pays for itself at 30k+ messages per month.
Wati — Best for Support-Heavy SMBs Needing a Simple Team Inbox
Wati's no-code chatbot builder and shared inbox are popular with small support teams. The caveat: the cheapest ₹1,999 Standard plan lacks the chatbot builder, pushing serious users to the ₹4,499 Pro plan. Wati shines for SMBs that prioritize human-agent chat over automation-heavy workflows.
RichAutomate — Best for Agencies, Developers, and Teams Without a Meta Card
Zero subscription floor, flat ₹0.10/msg platform fee on Client Pay, and the only BSP offering dual billing (Client Pay OR SaaS Pay inclusive) without Meta credit card. Built-in multi-tenant architecture with tenant-scoped API keys makes it the natural pick for marketing agencies reselling to D2C clients. Full public REST API and webhook contract for engineering teams building custom integrations. The trade-off: newer entrant in the Indian BSP space, smaller community, no Shopify one-click install yet.
Decision Framework: Which BSP Matches Your Business
| Your situation | Recommended BSP |
|---|---|
| Early-stage D2C, <20k msgs/month, running Meta ads | AiSensy (lowest floor + ad tooling) |
| Shopify-native D2C, 30k–200k msgs/month | Interakt (Shopify depth) |
| Small support team, 5k–30k msgs/month | Wati Pro (team inbox focus) |
| High-volume fintech or EdTech, 500k+ msgs/month | RichAutomate Client Pay (zero floor, flat markup) |
| Marketing agency with 5+ D2C clients | RichAutomate (multi-tenant + white-label) |
| No Meta credit card, need fast launch | RichAutomate SaaS Pay (₹1.20 inclusive) |
| Engineering team building custom flows | RichAutomate or Interakt (best API surface) |
Switching Costs Between BSPs
Migrating a WABA from one BSP to another is a 15-minute Meta handshake plus 2–7 days of operational prep. Your phone number, display name, green tick, quality rating, messaging tier, and high-quality approved templates all travel with you. What does not: chatbot flows (rebuild required — each BSP uses a proprietary format), chat history, contact attributes, and custom segments. Budget 2 business days for the switch. The dedicated migration guide for Indian D2C teams covers the full pre-migration checklist, the four failure modes that block 40% of first-attempt migrations, and the GST invoice reconciliation.
Final Thoughts for 2026
The WhatsApp BSP market in India is crowded but differentiated. Every BSP runs the same Meta Cloud API. The real purchase decision is billing-model flexibility, platform markup at your specific volume, and what features you need beyond core messaging. Audit your actual monthly volume honestly, pick the BSP whose floor-plus-markup curve matches your growth arc, and confirm the migration exit is clean before signing any annual contract. You can always switch — but each switch costs real engineering time.
