This resonates a lot — I've built WhatsApp automation systems for clients in India and the multi-channel chaos is real. The visual flow builder + AI chatbot combo is especially powerful because it lets non-technical business owners actually customize their responses without writing code. One thing I'd suggest looking into: automated invoice and payment follow-ups through the platform. For small businesses, the biggest ROI from messaging isn't just customer support — it's closing the payment loop. Built exactly this for a CA firm recently and it cut their collection time by 60%. The Redis-based rate limiting approach is smart. Keep building!
