Website chat and WhatsApp for small businesses: turning visitors into enquiries

Why visitors leave without asking

A visitor who is close to buying usually has one specific question. Do you deliver to my town? Can you do it this week? Does the price include installation? If the answer is on the page, good. If it is not, the visitor has three options: fill in a form and wait, call during office hours, or go back to the search results, where a competitor is one tap away. On a phone, at nine in the evening, the third option wins most of the time.

Chat and WhatsApp work because they change the cost of asking. Typing a question into a box that is already open feels like no commitment at all, and for many people WhatsApp is where they already are. Neither is magic, and neither makes up for a page that does not say what you sell, where and for how much. But on a site that already answers the common questions, they catch the uncommon ones, which are often the ones from people ready to buy.

The common mistake is to treat chat as a feature to switch on. It is a promise. A chat box tells the visitor that someone, or something, will answer now. A chat that sits unanswered until the next morning does more harm than having no chat, because the visitor asked and was ignored. Before you add one, decide who answers, when, and what happens out of hours. The rest of this guide is mostly about making that promise one you can keep.

It also helps to be clear about the goal. The point is not the number of conversations. It is the number of enquiries that turn into a quote, a booking or a sale, and the number of customers who did not leave with their question unanswered. A small number of good conversations beats a busy inbox of people asking what your opening hours are because the page did not say.

Fix the page before you add a chat

The cheapest enquiry is the one your page answers on its own. Before you add any chat, read your three most visited pages as a stranger would and check that each one answers the questions people actually ask. Your own inbox is the best list: the questions you answer every week by email or phone should be on the page.

• What you sell, in one sentence, at the top, in the words a customer would use rather than the ones on your business card.
• Where you work and when. Area served, opening hours, how soon you can start.
• Prices, or how you price. A range or a "from" figure removes the question that most often stops a visitor from writing at all.
• One clear next step on every page, the same one, not five competing buttons.
• A short contact form. Name, a way to reply, and the question. Every extra field loses people.

A short form brings a problem of its own: spam. In October 2026 our contact form started receiving gibberish submissions that had passed Cloudflare's Turnstile check, which is meant to stop bots. A bot check at the door is not enough on its own, so we added checks on the content of each submission as well, and a submission that fails them sends no email at all. That last part matters more than it sounds: bots use contact forms to make your site send its confirmation email to strangers, which damages your email reputation. If your form sends an automatic reply, make sure spam cannot trigger it.

Keep chat widgets polite, too. Google's guidance on page experience asks sites not to cover the content with overlays that get in the reader's way. A small launcher in a corner is fine. A chat window that opens by itself over the text on a phone is the kind of thing that page describes, and it annoys the visitor before it has helped anyone.

Web chat, WhatsApp or a form: which one when

The three are not competitors. They suit different moments, and most small businesses end up with a form plus one of the other two. The table sets out the differences that matter when you choose.

Web chat is strongest at the moment of doubt: the visitor is on your page, and the answer keeps them there. Its weakness is that the conversation usually ends when the visitor closes the tab, unless they left an email or phone number. WhatsApp is the opposite. The conversation lives in the customer's phone and can continue for days, which makes it good for quotes, bookings and follow-ups, but it takes the visitor off your site and it comes with Meta's rules.

For WhatsApp there are two products, and the choice matters. The WhatsApp Business app is built for the small business owner: free, on one phone, answered by hand. The WhatsApp Business Platform is the version for messaging at scale through an API, which is what you need to connect an inbox shared by several people or an automated assistant. Start with the app if you answer every message yourself. Move to the Platform when you want more than one person, or an assistant, on the same number.

A single inbox for everything is worth more than it seems. Tools such as Chatwoot, which we use, bring live chat, email and WhatsApp into one account, so a customer who starts on the website and continues on WhatsApp is still one conversation for whoever answers.

WhatsApp's rules and fees, in plain terms

Most problems small businesses have with WhatsApp come from four rules. They are all in Meta's own documentation, and they apply whether a person or an assistant does the typing.

The 24-hour window. When a customer messages or calls you, a 24-hour customer service window opens, and every new message from them restarts it. Inside the window you can reply as you like. Outside it, you can only send pre-approved template messages. In practice: answer while the window is open, and do not plan follow-ups that depend on free-form messages a week later.

Permission first. Meta's Business Messaging Policy requires that you have received opt-in permission from the person before you send them messages. A customer who writes to you has started the conversation; a list of phone numbers you collected for something else is not permission.

A way to reach a person. The same policy requires businesses that automate conversations to offer prompt, clear and direct escalation paths, such as handing the chat to a human agent. An assistant that cannot pass a customer to a person breaks the rule, not just good manners.

Fees, on the Platform. Since 1 July 2025 Meta charges per message delivered, not per conversation. Each business number gets a free tier of 1,000 service messages, the replies you send in the customer service window, per month, and service messages beyond it are charged, except for eligible government and non-profit organisations. Messages from customers to you are not charged. For a small business answering a few dozen conversations a week, the free tier may cover all of it; for a busy shop it will not, and those fees are Meta's, paid on your own account. We wrote up what changed for support replies in October 2026 separately.

Putting AI on the chat without losing trust

An AI assistant fixes the hardest part of chat, answering at nine in the evening, and it creates a new risk: answering wrongly with total confidence. A customer who is quoted a price you do not charge, or promised a delivery date you cannot meet, is worse off than one who got no reply. The rules below are the ones that keep an assistant useful.

• It answers only from what you have published. Your pages, your catalogue with its prices, your FAQ. If something is not there, the assistant says so and passes the question on. Most of the damage done by chatbots comes from letting them fill gaps.
• It says it is an AI. In the EU this is the law: the AI Act's transparency article requires that people are informed they are interacting with an AI system unless it is obvious, and the regulation applies from 2 August 2026. Outside the EU it is still the honest default, and customers take it well when the assistant is quick and correct.
• It hands over early. Anyone who wants to buy, leaves their details, complains, or asks for a person goes to a human, with a summary, at once.
• The handoff has a clock. If nobody picks the conversation up, the customer must not be left in silence. Decide in advance how long the assistant waits before it takes the conversation back and tells the customer what happens next.
• Someone reads the transcripts. Once a week, read a handful of conversations end to end. It is the only way to find the questions your website does not answer, and they belong on the page, not just in the chat.

Conversations contain personal data, names, phone numbers and sometimes much more, so treat the transcripts like any other customer record: mention the chat in your privacy policy, keep only what you need, and check where your chat software stores the data. Spain's data protection authority reminds organisations using AI that people are entitled to clear, accessible information about how their data is processed; a line in your privacy policy and a short notice in the chat cover the basics.

How we run ours, and the mistake we made

On biglobster.top a visitor can reach us three ways, and all three land in one place. The chat launcher in the bottom-left corner of every page, our WhatsApp number in the footer, and the same number behind the QR code on the landing page we share with local customers all arrive in a single Chatwoot account. The same AI assistant answers on both channels, from the same information, and it introduces itself as an AI.

Three decisions came from getting it wrong first. Until 19 October 2026 we had two floating buttons, a chat bubble and a WhatsApp bubble. Since both reached the same inbox and the same assistant, the second one only competed with the first, so we removed the WhatsApp bubble and kept WhatsApp as a footer link. We also moved the chat to the left, because the cookie banner's buttons sit on the right on a phone, and the chat bubble now lifts above the banner while it is showing instead of covering it.

The bigger lesson was about what the assistant knows. It answers from a feed our website publishes for it: our products and prices from the same file that sets them on the pricing page, the text of our main pages, our FAQ and the summaries of recent articles. Before 13 October that feed had no products and no pages in it. When a visitor asked what we offer, the assistant had nothing to answer from but our tagline, and it answered with the tagline. Nothing was broken in the software. It simply could not say what we had not given it. If your assistant gives vague answers, look at what it is reading before you blame the model.

The handoff works the way the previous section describes. When someone wants to buy, leaves their details or asks for a person, the assistant sends a Telegram alert with who they are, what they need and a link to reply from a phone. If nobody answers within 15 minutes, it takes the conversation back so the customer is never left waiting in silence. This is the setup we now sell as the Chat Assistant; the Meta fees for WhatsApp messages stay on the customer's own account, as they do on ours.

Measuring whether it works

Chat produces a lot of activity, and most of it is easy to count and useless to know. Count the things that tell you whether a visitor became an enquiry, and whether the enquiry became business. You do not need special software for this: a privacy-friendly analytics tool that records clicks on your chat launcher and contact buttons, and a weekly look at the inbox, are enough.

Give it two months before you judge. The first weeks are noisy: friends testing it, bots, people asking about opening hours. What you are looking for is a steady trickle of handoffs from people who want to buy, and a shrinking list of questions the assistant could not answer, because each of those turned into a line on your website.

Watch one more thing: the questions themselves. They are the most direct research into what your customers want to know, and they feed the rest of your website. A question that comes up every week deserves a sentence on the relevant page, and a few of them together can deserve a page of their own.

When not to add a chat

Chat is not for every business. If you cannot answer within the same day, and you do not want an assistant answering for you, a clear contact form and a phone number set an honest expectation that a chat would break. The same goes for businesses where every enquiry needs a site visit or a long conversation: the chat only adds a step before the call.

Do not add an assistant if your website does not yet say what you sell, where and for how much. It can only repeat what it reads, so it will repeat the gaps, politely and at length. Fix the page first; the assistant is worth more on a site that already answers the common questions.

Be careful with WhatsApp if your customers did not ask to hear from you there. Messaging people who have not opted in breaks Meta's policy and can get your number restricted, and buying a list of numbers is the fastest way to lose the channel altogether.

And do not pick the tool before the process. Decide who answers, in what hours, how quickly, and what the assistant may and may not say. Write it on one page. Any decent chat software will then do the job; without that page, none of them will.

Frequently asked questions

Is WhatsApp free for a small business?

The WhatsApp Business app is free. On the WhatsApp Business Platform, Meta charges per message delivered; each business number gets 1,000 free service messages a month, and messages from customers to you are not charged.

Can I message customers on WhatsApp whenever I like?

Only within 24 hours of their last message, freely. Outside that customer service window you can send only pre-approved template messages, and only to people who have opted in to hear from you.

Do I have to tell customers they are talking to an AI?

In the EU, yes: the AI Act requires people to be informed that they are interacting with an AI system unless it is obvious, and it applies from 2 August 2026. Elsewhere it is still good practice.

Web chat or WhatsApp: which should I start with?

Start with whichever your customers already use and you can answer reliably. Web chat catches questions while visitors browse; WhatsApp keeps conversations going for days. Many small businesses end up with both in one inbox.

What should an AI chat assistant never do?

Invent prices, dates or promises that are not on your website, pretend to be a person, or keep a customer who wants a human from reaching one.
