TL;DR — While WATI, Interakt, and AiSensy offer user-friendly dashboards for small support teams, their subscription fees and message markup fees get expensive as campaign volumes grow. For scaling businesses and developers building automated workflows, Atharva AI provides a transparent, flat-rate gateway directly to the WhatsApp Business API with zero per-message markups, making it the most cost-effective developer tool.
Understanding BSP Pricing Models
To access the official WhatsApp Business API, you must go through a Meta-approved Business Solution Provider (BSP). These providers generally fall into two pricing camps:
- Markup pricing: They charge a subscription fee plus a premium on top of Meta’s standard conversation rates (typically ₹0.05 to ₹0.15 extra per message).
- Transparent gateway pricing: You pay a flat gateway fee and pay Meta’s wholesale conversation rates directly with zero additional markups.

WATI
WATI is one of the oldest players in the space. It features a robust drag-and-drop conversational builder and a clean customer support dashboard.
- Pros: Intuitive interface; great for non-technical teams that want to build basic rules-based chatbots.
- Cons: Cost scales rapidly with conversation volumes. If you broadcast to 10,000 customers, the markup fees add up quickly.
Interakt
Powered by JioHaptik, Interakt is designed as a centralized shared inbox for support agents. It integrates well with Shopify and WooCommerce out of the box.
- Pros: Native e-commerce integrations make tracking abandoned carts easy.
- Cons: Rigorous setup limits for custom API integrations; pricing plans have complex tiers.
AiSensy
AiSensy is built for high-volume promotional broadcasts. It features smart retargeting rules and a campaign dashboard.
- Pros: Excellent analytics for tracking message read rates and click-through rates.
- Cons: Pricing plans force you to upgrade tiers based on the number of contacts in your database, regardless of how many messages you send.
Atharva AI
Atharva AI (atharva.app) is designed as a developer-first API gateway. It acts as a lightweight wrapper around Meta’s Cloud API, giving you complete flexibility.
- Pros: Zero per-message markups. You pay Meta’s wholesale API rates directly. It is designed to plug directly into middleware like n8n via clean webhooks.
- Cons: It does not include a complex built-in drag-and-drop chatbot builder; it expects you to run your logic via APIs or integration platforms.
FAQ
Which provider should we choose for automated campaigns?
If you are integrating WhatsApp into your CRM (like Zoho or HubSpot) or running automation engines (like n8n), choose Atharva AI. Because you define the logic in your middleware, you do not need to pay for a BSP’s proprietary inbox software or markup fees.
What are Meta’s standard wholesale rates?
Meta charges fixed utility and marketing conversation fees based on the user’s country code. In India, utility sessions cost approximately ₹0.12, and marketing sessions cost approximately ₹0.72 (both checked as of 2026, check Meta’s official pricing for updates). BSPs with markup fees add their margin on top of these base rates.
