WhatsApp has been an integral part of the daily lives of millions of people in Spain for years, used for everything from chatting with family and friends to resolving issues with shops and service providers. Now, Meta is preparing an adjustment to how it charges businesses that use its professional platform, a move that isn't aimed at the average user.
The change pertains to WhatsApp Business Platform, the infrastructure that many companies connect to their customer service systems, CRM, or chatbots. Starting October 1, 2026 , organizations operating through the API will have to pay for certain messages, although personal accounts and the basic WhatsApp Business app will continue to send and receive messages free of charge.
What's changing in WhatsApp Business Platform
Until now, when a customer contacted a company, a 24-hour window opened during which the business could respond with service messages at no additional cost. With the new model, each response sent within that window is billed separately , regardless of whether it's written by a person or an automated system.
The time it takes the company to respond is no longer the main factor. What matters is the number of messages delivered , so a chatbot that divides a response into four fragments can generate four charges.
Utility templates also come into play; these are communications designed to confirm orders, notify payments, or update account information. These templates are charged from the first shipment and are not dependent on the customer service franchise.
Meta maintains a pool of 1.000 free service messages per month for each business number . Once that limit is exceeded, support responses begin to be counted.
This system comes after the company replaced the charge per complete conversation with billing linked to each message in 2025.
Who pays and who gets left out
The first point to clarify is that individual users do not pay anything to contact a company or to receive a response. The personal WhatsApp application is completely exempt from this policy.
It's also not aimed, in principle, at freelancers and small businesses that use the free WhatsApp Business app on their mobile phones. That standard version doesn't include extra charges per message.
Those affected are companies that work with WhatsApp Business Platform or its API, especially if they connect it to a CRM, an external provider, or automation tools. This is the typical environment for large support teams and high-volume conversations.
Therefore, we are not talking about the typical Business account that a business manages manually, but about infrastructures designed to handle thousands of interactions.
Prices, impact and the case of Spain
In Spain, there is still no official published rate for these messages. Meta has indicated that the cost will be aligned with the utility and authentication prices in the recipient's market , so the bill will depend on the customer's country.
This means there is no single price and each company will have to review its provider, the type of communication, and the destination of its messages.
As an international reference, in Brazil a figure of $0,0068 per service message has been used , although this is a local rate that cannot be directly transferred to the Spanish market.
Estimates are also circulating based on a cost of $2 per million tokens, with approximate figures of between 4 and 20 cents for transactions of 20.000 to 25.000 tokens. These calculations are pending official confirmation for Spain.
Another date to keep in mind is September 30, 2026 , the deadline Meta has set for suppliers to register a payment method before it comes into effect.
The impact will be greatest for banks, online stores, delivery companies, and large retailers that use WhatsApp as a customer service channel. In these cases, a small cost per message can become a significant expense when managing thousands of conversations per month.
A small business receiving around 800 responses per month on a single issue won't pay anything because it remains within the franchise. With 5.000 responses per month, however, 4.000 would be billed.
Chatbots that break down a response into several short messages increase costs, since each message is charged separately. Therefore, it's advisable to consolidate information into fewer messages and review automated workflows.
There are exceptions that remain free of charge: conversations initiated from a Click to WhatsApp ad or a Facebook button maintain a free 72-hour window.
External AI solutions connected to the API are considered service messages and pay the same; Meta's own AI, the Meta Business Agent, has its own token consumption model.
It's also important to dispel myths: chain messages claiming that WhatsApp will charge users €0,50 and that forwarding the message to ten contacts avoids payment are false. WhatsApp does not charge individuals for using the application.
The practical consequence is that the change doesn't mean a generalized charge for everyone who uses WhatsApp, but rather an adjustment for large-scale businesses. Personal accounts and the basic Business app remain exempt from charges, while companies connected to the API will have to manage their usage, take advantage of the monthly allowance, and redesign their automations. In Spain, the final pricing structure for each market remains unknown, so consulting Meta and the provider will be crucial before the new system is fully implemented.
