WhatsApp will introduce local billing in India and Brazil by the second half of 2026, allowing businesses to pay in rupees and other local currencies, thereby reducing foreign exchange costs and complexities. This change, which includes an increase in marketing message rates from January 1, 2026, aims to simplify financial operations for Indian startups and enterprises. The move may also impact WhatsApp's existing business solution provider ecosystem as the platform expands direct access for larger customers.
