What's the best Android app for a small business to chat with customers and share a product catalog?

WhatsApp Business is a dedicated application designed for small business owners who need to communicate with customers using the familiar WhatsApp platform. It differentiates itself from the standard consumer app by adding several business-specific features. A key tool is the product catalog, which allows businesses to showcase their offerings with photos, descriptions, and prices directly within a chat. This is useful for a retailer who can quickly send a visual catalog link to a customer inquiring about items. To save time on frequent inquiries, the app includes automated greeting messages, quick replies for common questions, and away messages. A verified business profile adds a layer of trust for customers. However, some users report occasional technical hiccups, particularly with multi-device linking where calls might not sync properly across a primary and linked phone. Despite this, for businesses already operating in WhatsApp-centric markets, the app provides a straightforward, no-cost way to centralize customer communication and basic sales outreach without requiring a separate website or complex e-commerce setup.
