How to automate WhatsApp Business for your company: what is free, what needs a bot and what it costs

Any business can automate WhatsApp Business, and part of it can be done for free from the app itself. What the app cannot do (menus with options, replies at any hour, a link with your calendar) needs a bot on the WhatsApp platform, and that has a cost.

This guide explains, in plain words, what you can set up today, when it is worth moving to a bot and what you will pay. It is written for any business in Spain: we work remotely with clients across the country.

What you can automate for free with the WhatsApp Business app

The WhatsApp Business app includes several tools for businesses. According to the official app features page, these are the ones that save you time:

Greeting message

It is sent automatically when someone messages you for the first time. Use it so the client knows they are in the right place and what they can ask for. For example: "Hi, this is Laura from the clinic. Tell me what you need and I will reply as soon as I can. If you want an appointment, let us know the day and time that suits you".

Away message

It replies automatically outside your opening hours. The most common mistake is leaving it as "We are not available right now". Say when you will reply and what they can send in the meantime: "We will reply tomorrow from 9:00. Leave us your question and we will have the answer ready".

Quick replies (they are not automatic)

These are shortcuts for messages you repeat a lot: opening hours, address, prices, directions. They save a lot of time, but note: you send them yourself. They do not reply on their own.

Labels and catalog

Labels help you organise chats (new client, payment pending, appointment confirmed). The catalog shows your products or services inside WhatsApp, so you do not have to send photos and prices one by one.

What the app cannot do, such as automatic replies with options

One of the most common searches is how to set up "automatic replies with options" in WhatsApp Business: the classic "Press 1 to book, 2 for prices". The free app does not allow it. These are its main limits:

• There is only one greeting message and one away message. It does not reply differently depending on what the client asks.
• There are no menus with buttons or lists of options. Those are interactive messages, which run on the WhatsApp platform (API).
• It does not connect with your calendar, your online shop or your management software.
• It cannot hand a chat over to another team member depending on the topic.

For any of those you need a bot. It does not have to be complicated, but it does have to be well thought out.

When you need a WhatsApp bot

Not every business needs a bot. This table helps you see where you stand:

A good sign that you need one: you spend more than an hour a day answering the same things (hours, prices, availability, order status), or you lose clients because they write at night and you reply the next day.

Which automations save the most time in a business

What pays off most is rarely the most impressive. It is the small tasks repeated every day. Some examples by sector:

• Clinics and beauty centres: booking an appointment, confirming it and sending a reminder the day before to reduce no-shows.
• Academies and gyms: sharing timetables and prices, and booking a trial class.
• Online shops: answering where an order is and how returns work.
• Restaurants: booking a table and sharing the menu of the day.
• Home services: collecting job details (address, photos, urgency) before you call the client.

In every case the idea is the same: the bot handles the repetitive part and passes you a qualified client with the details you need to close the sale. That is how our business automation service works: first we see what repeats in your day-to-day, then we decide what to automate.

And if you have a website, add a clearly visible WhatsApp button: many of the chats the bot handles will start there.

How much it costs to automate WhatsApp Business in 2026

If you stick with the app, you pay nothing. If you move to a bot, the cost has two parts: what Meta charges for messages and what the tool or development costs.

What Meta charges per message and the October 1, 2026 change

According to Meta's official pricing documentation, since July 1, 2025 the platform charges per delivered message, and the price depends on the client's country and the message type. Spain has its own rate.

When a client messages you, a 24-hour window opens to serve them. Customer service messages inside that window used to be free, but since October 1, 2026 Meta charges for them beyond 1,000 free ones per number each month. Messages you start yourself (promotions, notices, verification codes) are sent with templates and are always paid.

For a small business, 1,000 service messages a month may be more than enough. If you have a lot of volume, run the numbers before building anything.

Ready-made tool, custom bot or AI

There are three routes, from simplest to most complete:

• Ready-made tool: you pay a monthly fee and set up flows with menus. It is quick to launch, but you adapt to the tool.
• Custom bot: designed for your business and connected to your calendar, shop or software. It has an upfront development cost and is usually cheaper to run when volume is high.
• AI bot: understands questions written in any way. Useful when enquiries vary a lot, but it must be well limited so it does not make up answers about prices or terms.

There is no single price. It depends on how many conversations you have, what the bot must do and what it connects to. Be wary of anyone who quotes a figure without asking you about any of that.

Mistakes that make clients leave

Bad automation is worse than none. These are the most common mistakes:

1. A bot with no way to reach a person. There must always be a clear "talk to someone" option.
2. Endless menus. If booking takes five screens, the client gives up. Three well-chosen options beat ten.
3. Sending promotions to people who did not ask for them. In Spain, the Information Society Services Act (article 21) bans commercial messages by electronic means without prior consent, except to existing clients about similar products. Unexpected messages can also get you blocked.
4. Automating before organising. If you do not know the ten questions you get most, the bot will not know how to answer them. Write them down for a week before building anything.
5. Replies that sound like a robot. Write the messages the way you talk in your business. Clients notice straight away when the tone is not yours.
