Karix vs AiConva: a cheaper WhatsApp BSP for Indian enterprises

Karix, now part of Tanla, is an enterprise-grade messaging provider with deep roots in Indian CPaaS. They serve large banks, enterprises, and high-volume senders well. The gap appears for mid-market and growing businesses: Karix's contract-driven model, enterprise minimums, and slower onboarding can be friction. Here's how AiConva compares for the segment Karix doesn't optimise for.

Contract vs self-serve

Karix typically requires a sales conversation, a contract, and a minimum commit — appropriate for an enterprise procurement cycle, painful for a scaling SMB. AiConva is fully self-serve: sign up, connect a WABA, and send within an hour. No contract, no minimum, no sales gate. The transparent rate (Meta at cost + ₹0.10/msg + GST) is the same whether you send 1,000 or 1,000,000 messages.

Pricing transparency

Enterprise messaging pricing is notoriously opaque — bundled rates, volume tiers, negotiated discounts that vary customer to customer. AiConva publishes one rate and applies it to everyone. For a mid-market business that lacks the leverage to negotiate a deep enterprise discount, that transparency is often the cheaper outcome in practice.

Where Karix leads

For genuine high-volume enterprise use — millions of OTPs daily, dedicated shortcodes, regulatory compliance work, custom SLAs — Karix/Tanla's infrastructure and account management are hard to beat. If you're that customer, stay. If you're a growing business that wants WhatsApp without an enterprise contract, AiConva is built for you.
