Replying on WhatsApp is no longer free

For two years a WhatsApp conversation had a flat price. You paid to open it and whatever came next was free: three messages or forty.

As of today you pay per message. That turns the length of your conversations into a budget line, and most of what can be done about it is configuration, not redesign.

What is charged now

The mechanics of when you can send did not move. The customer service window still lasts 24 hours and still resets every time the customer writes. Reactions — the emoji on a message — are still free and do not even draw from the allowance. Governments and non-profits Meta recognises as eligible keep service free through December 31, 2027.

There is a second window worth not confusing with the service one, and this change left it untouched. When a customer arrives through a Click-to-WhatsApp ad or a Facebook Page call-to-action button and the business replies within the first 24 hours, that reply is not charged and opens a 72-hour free entry point window: while it runs, no message to that customer is billed, including templates that normally are. It decides what is charged, not what can be sent: a service message still needs the 24-hour window open.

The four rules that set your invoice

Every lever below comes out of these four.

You are charged per delivered message, not per conversation. The unit of cost stopped being the case and became the bubble.

Service has no volume discount. Meta’s tiers lower the price of utility and authentication as monthly sending grows. Service is not in that table: the one category that grows with the length of your conversations is the one you cannot negotiate down by scale.

The 1,000 free are per number, not per account, and they are a single allowance shared between 1:1 and group sends. For an operation handling thousands of cases a month they are gone in a day: a cushion for someone starting out, not a lever for an institution.

With no payment method, delivery stops. Meta delivers what fits inside the allowance and stops delivering the rest. No invoice arrives later: support goes down at message 1,001.

What a reply costs

The range runs 1 to 37 between Colombia and Peru. A regional operation treating its WhatsApp cost as a single number is averaging markets that differ by an order of magnitude.

It is worth looking at the other column too. In Mexico a marketing message costs $0.0397 and a service message $0.0085: 4.7 times more. The category each message goes out under weighs more than any volume negotiation.

Seven adjustments so you do not overpay

None of them requires changing provider or rebuilding the operation. They run from most to least impact, and the first four are configured in the agent.

In the agent

1. One reply, one message. Bubbling is the most profitable adjustment and the easiest: a greeting, a clarification and the answer in three bubbles are three billed messages where one would do. If your agent is set to “reply naturally” by splitting text, that now triples the cost of every turn.

2. Ask for all the data at once. An agent that asks for the ID, then the account number, then the date spends three messages and three waits. A single message asking for all three resolves the same and costs a third. With buttons or a list where possible: every misunderstanding is two more turns.

3. Cut the messages that do nothing. “One moment please”, “thanks for writing”, “anything else I can help with?”. They do not resolve, do not inform and are now billed. In an agent this is an explicit rule in its policy, not a style preference.

4. Acknowledge with a reaction. It is the only service message type still free, and it does not draw from the allowance either. Where a “✔ received” goes out as a message today, a reaction does the same job for nothing.

In the templates

5. Review every template’s category. Meta states in writing that the assigned category is the business’s responsibility, and that using a template means accepting the charges of whatever category it carries at that moment. A template that should be utility but is classified as marketing costs almost five times more in Mexico. Worth one pass over the full list.

6. Do not push to a template what fits in the window. With the 24-hour window open, replying with a service message costs the utility rate. Replying with a marketing template costs the marketing rate. Same content, same conversation, four or five times the difference.

In the operation

7. Shift spend to Click-to-WhatsApp and load the payment method. Conversations that start from an ad, or from a Facebook Page call-to-action button, open a 72-hour free entry point window in which nothing is billed. It is the only large surface left unbilled. And the payment method is not administrative: it is the one item on this list that can leave an operation unable to reply.

The same case, two flows

That last figure is arithmetic, not a promise: four fewer messages per case, multiplied by your market’s rate and by your monthly cases. The WhatsApp calculator runs it with your own numbers, with the free allowance and the ads window already deducted.

The metric that just changed price

While the window was free, the question for an operation was how many conversations can I open. From today it is how many messages does it take me to close one.

Almost nobody has that second one on a dashboard, because until yesterday it cost nothing. It is the first thing worth instrumenting: without it, the seven adjustments above are applied blind and there is no way to tell which one worked. The walkthrough of a support operation shows where it gets measured, from the enquiry coming in to the case closed.

The underlying read

Meta spent two years giving away the expensive part of the conversation so that businesses would move to the channel. The move already happened, and today the subsidy ends.

For an institution running volume that is neither bad news nor good: it is a change of incentive. Until yesterday a long conversation and a short one cost the same, which is why nobody separated them. From today the short conversation — the one that resolves in two messages instead of six — went from being a courtesy to the customer to being a line in the budget.
