Why This Comparison is Important in 2025
WhatsApp surpassed 3.1 billion monthly active users early in 2025, solidifying its place as the world’s de-facto business-to-consumer channel. Whether your business is a Shopify store in Karachi or a SaaS company in Singapore, your top-line growth frequently depends on how effectively you can collect leads, send broadcasts, and close tickets over WhatsApp.
Two players dominate Pakistani-Indian SMB talk currently:
- Interakt – a Meta-approved WhatsApp Business API BSP (Business Service Provider) for conversational commerce and support automation.
- LeadsFunda’s WhatsApp Sender Pro (WSP) – a stand-alone Windows/Linux/Mac application that combines bulk sender, scraper, number filter, and group-management scripts into one lifetime licence.
Both offer “24/7 engagement,” but the philosophies of the two couldn’t be more opposite. This report analyzes every feature, price level, and compliance subtlety so you can invest wisely.

Deep-Dive: Interakt
Business Model & Architecture
Interakt is a BSP under Meta’s partner programme. You sign a SaaS agreement, validate your Facebook Business Manager, and receive an WhatsApp Business API number hosted on Interakt servers. That means:
- 99.9% uptime on ISO-certified infra
- Automatic API version upgrades when Meta updates versions
- Conversation-based billing corresponding to Meta’s current four-bucket model (Service, Utility, Marketing, Authentication)
Key Feature Set
Internally tag, assign, and comment on tickets; ideal for support SLAs.
2. Official Catalog & Cart
Keep product feeds in sync so customers can shop & pay within chat.
3. Click-to-WhatsApp Ad Attribution
Auto-open chat from Meta ads.
4. Broadcast Engine
Upload CSV of opted-in contacts, send template messages, check delivery analytics.
5. GPT/Flow Chatbots
New 2025 beta has GPT-4o Llama-3 backend; however some docs continue to state “no chatbot,” which is confusing.
6. CRM & E-commerce Apps
One-click integrations with Shopify, Zoho CRM, Salesforce, Razorpay, etc.
7. Analytics & Revenue Attribution
Attribute revenue from catalog Carts; still does not have broadcast attribution.
Pros & Cons Round-up
Pros
- Cost-effective compared to other BSPs; quarterly billing mitigates churn
- Scalable – multiple numbers, arbitrary agents

Cons
- No broadcast retry – automatic re-send of failed sends due to template rejection is not done; manual fix required
- Dashboard learning curve – reviewers reference complexity
- Email-only support with 48-72 h SLA
- Additional Meta per-conversation fees are cumulative; budgeting is complicated
