Reviewers see WhatsApp Business as a practical way for small businesses to handle customer chats, especially one-to-one sales and support. The most praised features are Quick Replies, labels, and business-hours messaging, which help organize inquiries, reduce repetitive work, and keep personal numbers separate from customer conversations. The main complaint is setup and support: account verification can feel rigid, blocked numbers are frustrating, and help from support is often slow. Founder feedback is sparse but points to real use around the WhatsApp API for automated customer conversations.
