The most consequential change comes from the new pricing model: starting 1 October, Meta will begin charging businesses individually for each service message sent via WhatsApp Business, abandoning the previous model that billed per conversational window. This shift, announced in a meeting with Meta representatives, directly ties operational costs to conversational efficiency, punishing long-journey operations with inflated bills. A simulation by Hi Platform, which hosted the event, showed that an operation handling 10,000 attendances per month with an average of nine company-sent messages per conversation could see monthly costs rise by around R$7,200. Conversely, trimming just three messages per interaction could yield annual savings approaching R$30,000, making message reduction a financial imperative.

The pricing overhaul arrives alongside a global rollout of usernames, which began in Colombia on 20 July and now extends to the platform’s 3 billion-plus users. The feature allows individuals to be contacted via a unique @handle rather than a phone number, hiding the underlying number from those who have not saved it. To initiate a chat, one must know the exact username, adding a security barrier. The system also notifies users if a new contact’s account is registered in a different country, a guard against spam and fraud. Business accounts gain priority in claiming usernames matching their verified brands, and the integration with Meta’s Bsuid persistent customer identifier ensures uninterrupted messaging histories even when users hide their personal numbers.

WhatsApp is also extending real-time communication to its web client, eliminating the need for desktop app installations. Voice and video calls, protected by end-to-end encryption, can now be placed directly from a browser, with screen sharing, reactions, and call history integrated. A new call transfer feature lets users move an active group call between devices without disconnecting, while a waiting room option gives hosts approval control over joiners. Technical improvements include QuickHD for faster video resolution stabilization and a background noise suppression system.

Businesses are being nudged to rethink conversational design. Hi Platform’s head of customer experience stressed that efficiency now directly impacts costs, urging the use of interactive buttons, forms and AI-driven intent detection to shorten interactions. Concurrently, a beta test of a voice-note widget for Android hints at further streamlining of user-to-user messaging, though no public release date has been set. The web calling features, however, are being rolled out gradually and will soon be globally available, according to Meta.

For the millions of enterprises that rely on WhatsApp for sales and support, the 1 October deadline represents a hard pivot toward leaner conversational flows. The simultaneous arrival of usernames and web calling signals a platform-wide push to deepen its utility across both personal and commercial spheres, but the per-message pricing – and the cost pressure it introduces – will likely dominate the near-term strategic conversation.
