Pricing Deep Dive
WATI
WATI uses a per-seat model. The Growth plan is $39/month for 5 agents — a 10-person team easily hits $80–$100+/month just in seat costs, before Meta fees. WATI also adds ~20% markup on Meta's per-message rates. Across G2 reviews, "expensive" appears 39 times and "pricing issues" 23 times.
AiSensy
One of the most affordable entry points in India at ₹999/month. Very strong on broadcasts — 210,000+ businesses use it. Less depth on shared inbox and CRM-style features.
Interakt
Strong Shopify and WooCommerce integration. Unlimited agents from the start. INR billing. The automation builder is solid for ecommerce flows. Less developer-friendly.
Tenreply
Unlimited agents on all plans, no per-seat fee. Built around the shared inbox for teams, with flow automation, broadcasts, contact CRM, catalog, and a REST API with webhooks. INR billing. Starter at ₹1,999/month covers unlimited agents and all core features.
