WhatsApp is free, but it has a special model of earning, which is mainly focused on business users. WhatsApp is free for individual users, but it earns money from business customers. Companies can communicate directly with customers using the WhatsApp Business app, such as order confirmation, shipment tracking, or customer support.

Big companies get some premium services and API facilities to communicate directly with customers, for which they pay WhatsApp. WhatsApp is now simplifying business conversations and transactions, allowing customers to make ticket booking, payments, and other services directly through chat. Companies pay for these features, which earns WhatsApp. Companies bring users directly to WhatsApp chat by advertising on Facebook or Instagram, for which Meta charges money.

Overall, WhatsApp generates revenue through business services and advertising even though it is free. WhatsApp also charges money for blue ticks from business accounts.
