Facebook's WhatsUp introduces catalogs, a mobile storefront for businesses to showcase and share their products.

Available in the WhatsApp Business app, Catalogs allows businesses show their full product lineup right within the app.This makes business owners look more professional and keeps customers engaged in the chat without having to visit a website.

For each item in its catalog, a business can add information including price, description and product code. WhatsApp hosts these catalogs to save storage space on the phones of both businesses and customers.

The catalog feature is available today to businesses using the WhatsApp Business app on both Android and iPhone in Brazil, Germany, India, Indonesia, Mexico, the UK and the US. It will be rolling out around the world soon.

WhatsApp launched its Business app in early 2018, allowing businesses to display their official bio, email, address and contact number. It also gives them access to messaging metrics and other business-oriented tools.
