Every week we get emails from customers who left WATI, AiSensy, or Interakt for us. Every one starts the same way: "The sticker price wasn't what I actually paid."
This post is the honest 4-way comparison I wish existed when I was picking a BSP three years ago. Sticker price, add-ons, hidden fees, and — the number that actually matters — total month-1 bill for a real team.
All four vendors — AiSensy, WATI, Interakt, and Go4whatsup — are Meta-authorized WhatsApp Business Solution Providers (BSPs). Your WhatsApp Business number runs on the same official API on any of them. The dashboard, AI features, per-message margin, and pricing structure are what differ.
The sticker price is not the actual price
Every BSP shows a starting price on their landing page. Under the hood, the actual monthly bill has 4-6 layers:
- Platform subscription — the sticker price
- Meta's per-message fee — charged per delivered template message, by country + category
- BSP's margin on Meta's rate — varies by provider
- Per-agent seat fees — kicks in above the base allowance
- AI or add-on modules — sold separately on lower tiers
- Setup / onboarding fees — one-time, sometimes waived
To make this comparable, I built the same scenario for all four: a 10-agent B2C team in India that wants AI on the plan.
Sticker price comparison
1 AiSensy — $45/month (Basic)
1 owner + 5 agents included, AI as an add-onWhat's in the box: 1 owner + 5 agents, unlimited contacts, basic analytics, template management. No AI reply without the add-on. No CRM sync beyond Zapier. AiSensy also has a Free Forever plan.
To add: agents 6-9 = $20/agent/month ($80 extra for 1 owner + 9 agents). AI Agent add-on = $50/month for 1,000 AI messages. Chatbot flow builder add-on = $80/month for 5 chatbots.
2 WATI — $59/month (Growth)
3 users included, AI credits on every planWhat's in the box: 3 users, keyword chatbot, template broadcast, HubSpot integration, basic analytics. Shopify integration is a $4.99/month add-on.
To add: Growth allows no extra users. For 10 agents you need Pro ($119/month, 5 users) plus 5 extra users at $39 each ($195 extra). Wati includes monthly AI credits on every plan (2,000 a month on Growth, 5,000 on Pro), with more credits available as a paid add-on.
3 Interakt — $55/month (Growth)
Agents not capped, AI as an add-onWhat's in the box: Agents not capped, Shopify + WooCommerce native, chatbot flow builder, campaigns, basic analytics.
To add: no extra agent fees. Advanced is $69/month. The WhatsApp AI Agents add-on is $74.99/month on Growth and Advanced.
4 Go4whatsup — $39/month (Standard)
Up to 5 users, AI chatbot add-onWhat's in the box: Up to 5 users, chatbot builder, auto-translate in 100+ languages, AI chatbot as an add-on (included in Pro and Enterprise), Zoho and Shopify native on Premium ($79), Odoo on PRO, campaigns, full analytics.
To add: 10 agents means the Premium plan ($79/month, 10 users included). The AI chatbot (auto-replies and AI-drafted replies for agents) is an add-on on Standard, priced by AI usage — ask sales for a quote. Enterprise tier only if you need a dedicated success manager.
Platform fee for a 10-agent team with AI (India)
Meta's per-message list rate is the same on all four. India rates from 1 October 2026: Marketing $0.0118, Utility and Authentication $0.0014; the first 1,000 Service replies per number each month are free. For scale, a mix of about 3,050 messages a month (800 Marketing, 1,500 Utility, 50 Authentication, 700 Service) costs about $12.27 at Meta's list rate in India, including the 7% surcharge on Marketing. Each BSP adds its own margin on top. What differs is that margin + agent seats + AI add-on, so the table below compares platform fees only.
| Line item | AiSensy | WATI | Interakt | Go4whatsup |
|---|---|---|---|---|
| Platform fee | $45 (Basic) | $119 (Pro) | $55 (Growth) | $79 (Premium) |
| Extra agents (to reach 10) | $80 (4 × $20) | $195 (5 × $39) | $0 (not capped) | $0 (in Premium) |
| AI add-on | $50 (AI Agent) | $0 (AI credits included) | $74.99 (AI Agents) | Add-on on Standard (priced by AI usage) · included in Pro & Enterprise |
| Setup fee (month 1 only) | Check with vendor (not in total) | $0 | $0 (none listed) | $0 |
| Meta's per-message fee | Same list rate + BSP margin | Same list rate + BSP margin | Same list rate + BSP margin | Same list rate + Go4whatsup margin |
| Month-1 platform total (before Meta fees) | $175 | $314 | $129.99 | $79* |
| Steady-state monthly platform fee (from M2) | $175 | $314 | $129.99 | $79* |
* Go4whatsup's AI chatbot add-on is priced by AI usage, so the Go4whatsup totals do not include an AI line. AI is included in Pro and Enterprise.
Steady-state gap: before Go4whatsup's AI chatbot add-on, Go4whatsup Premium's $79 platform fee is $96/month below AiSensy and $235/month below WATI for 10 agents ($1,152 and $2,820 a year). Interakt Growth costs less at $55/month if you skip its $74.99 AI add-on. Meta's per-message list rates are the same everywhere.
AiSensy vs Interakt
AiSensy vs Interakt comes down to how your team size grows. AiSensy has a free plan and a $45 Basic plan for 1 owner + 5 agents, with extra agents at $20 each. Interakt starts at $55 a month on Growth and does not cap agents on any plan.
| AiSensy | Interakt | |
|---|---|---|
| Price | Basic $45/month (₹1,500 in India) | Growth $55/month · Advanced $69/month |
| Agents | 1 owner + 5 agents on Basic; extra agents $20 each | Not capped on any plan |
| AI add-on | AI Agent $50/month for 1,000 AI messages | WhatsApp AI Agents $74.99/month on Growth and Advanced |
| Meta charges | Per delivered message on top of the plan; India rates published by AiSensy include its margin (Marketing ₹1.09, Utility/Authentication/Service ₹0.145) | Per delivered message on top of the plan; check Interakt's current rates |
| Free plan | Yes (Free Forever plan) | None listed (Growth, Advanced, Enterprise on request) |
Checked: November 2026, on aisensy.com/pricing and interakt.shop/pricing.
Verdict: AiSensy costs less to start (free plan, $45 Basic, $50 AI add-on), while Interakt costs less for bigger teams because its $55 Growth plan does not cap agents — 10 agents on AiSensy Basic come to $125 a month.
It's not just about price — 4 things beyond the sticker
1. AI packaging
AI pricing differs by provider — per plan, per AI credit or per AI conversation. WATI includes monthly AI credits on every plan (Growth 2,000, Pro 5,000, Business 20,000), with more credits available as a paid add-on. On Go4whatsup, the AI chatbot (auto-replies and AI-drafted replies for agents) is an add-on on Standard, priced by AI usage, and included in Pro and Enterprise. For teams where AI meaningfully changes conversion — cart recovery, appointment booking, lead qualification — ask each provider for the price at your monthly chat volume.
2. Integrations depth
All four connect to Zapier + Shopify + HubSpot. Deep native integrations vary:
- AiSensy: HubSpot is best-in-class. Zoho is competent. Odoo requires Zapier bridge.
- WATI: Shopify is best-in-class. HubSpot is solid. Zoho requires Zapier bridge.
- Interakt: Shopify + WooCommerce are best-in-class for e-commerce. Others via Zapier.
- Go4whatsup: Zoho + Odoo are best-in-class. Shopify is solid. HubSpot via native connector. Integrations start on Premium; Odoo is on PRO.
3. Regional pricing + support
WATI charges in USD globally. Interakt charges in USD globally. AiSensy prices in INR for India, USD elsewhere. Go4whatsup prices in local currency: ₹1,499/month in India, AED 149 in GCC, €39 in Europe, SAR 149 in Saudi. For non-US teams, this cuts FX conversion + card fees, and aligns invoicing with your local tax setup.
4. Onboarding time
Onboarding varies by provider: Interakt is self-serve on Growth and assisted on Advanced. Go4whatsup typically has customers live within about 24 hours once Meta verification is done (Meta Business Manager verification is the bottleneck, and it varies by business).
Who should pick which?
Pick AiSensy if
- You're HubSpot-native and want the deepest HubSpot integration
- You want a well-known brand name for internal procurement buy-in
- Budget is not a constraint and you specifically want their custom chatbot flows
Pick WATI if
- You're Shopify-native at scale and want the deepest Shopify integration
- You value the largest customer base + ecosystem for peer confidence
- You want a 5-user Pro plan with AI credits included
Pick Interakt if
- You run a Shopify + WooCommerce e-commerce operation and need deep native connectors
- You need agentless automation for high-volume order updates
- You have a large team: agents are not capped on any plan
Pick Go4whatsup if
- You want the same official-API access from $39/month for 5 users
- You use Zoho or Odoo as your primary business system
- You're a growing team and don't want per-agent price walls
- You're in GCC or Europe and want local-currency invoicing + local hours support
- You want auto-translate in 100+ languages, and AI included in Pro and Enterprise
How to switch BSPs (numbers are portable)
WhatsApp Business numbers are portable between BSPs — Meta handles the transfer. The process:
- Sign up with the new BSP. They apply for number transfer inside your Meta Business Manager.
- You approve the transfer request from within Meta Business Manager.
- Meta migrates the number (24-48 hours typical).
- Your templates re-sync. Chat history stays with the old BSP unless they export it for you.
- Cancel the old subscription only after the new one is fully live.
The two friction points are (a) making sure you keep template approvals and (b) exporting chat history from the old BSP before you leave. Most BSPs offer JSON or CSV export on request — ask before you sign the new contract.
The bottom line
For small B2C teams of up to 5 users, Go4whatsup Standard at $39 covers the core of what AiSensy Basic, WATI Growth, or Interakt Growth deliver — plus auto-translate in 100+ languages, plus billing in AED, SAR or INR (native Zoho is on Premium and Odoo is on PRO) — at a lower platform fee than their entry paid plans. At 10 agents, Interakt Growth ($55) costs less than Go4whatsup Premium ($79).
Pick the platform that matches your CRM stack + regional presence + AI needs. If those all point to Go4whatsup, great. If they point to a competitor because of a specific integration or brand comfort, that's a legitimate reason to pick differently. What isn't legitimate is picking on the sticker price alone and getting surprised by the month-1 bill.
