AI chatbots for small business: website vs WhatsApp
By the Codeventures team · 3 min read
Short answer
Put an AI chatbot on your website if most enquiries start there and you want it to book calls or capture leads. Put one on WhatsApp if customers already message you there, which is common for cafés, restaurants, clinics and local services. The best chatbots answer from your own information, hand over to a person when needed, and never guess.
Website chatbot or WhatsApp chatbot?
| Website chatbot | WhatsApp chatbot | |
|---|---|---|
| Where customers find it | On your site, while researching | In the chat app they already use |
| Best for | Answering pre-sales questions, capturing leads, booking calls | Quick questions, orders and bookings from repeat customers |
| Conversation style | Visitors browse, then leave | Ongoing threads customers come back to |
| Setup notes | Add a widget to your site | Requires the WhatsApp Business Platform and message templates for outbound messages |
Many businesses end up with both, powered by the same brain: one set of business information and rules, two front doors.
What a good AI chatbot actually does
Answers from your own information. Opening hours, menu, services, pricing guidance and policies. Grounding the bot in your content is what stops it inventing answers.
Knows when to hand over. Complaints, complex requests and anything sensitive should go to a person, with the conversation attached so the customer doesn't repeat themselves.
Takes action, not just questions. The most valuable bots book meetings, take reservations or capture a lead's details and pass them to your team.
Keeps each customer separate. Every conversation needs its own memory, so details never mix between people.
Two examples we've built
The assistant on this website, Cody, is a website chatbot with meeting booking: it answers questions about our services, checks live calendar availability and books a meeting after a one-time email code, so nothing lands in the calendar without a verified email.
For a café, we built a WhatsApp AI chatbot that answers the questions staff hear all day, like opening hours and menu, and passes anything else to a team member, so customers get instant replies even during the rush.
What to prepare before launch
- Your top 20 questions and the right answers, in plain language
- What the bot must never do, like promise refunds or quote custom prices
- The hand-off: who gets the conversation, and in which channel
- One action to automate first, such as booking, reservations or lead capture
WhatsApp-specific rules
WhatsApp is strict about business messaging. Customers can message you freely, and you can reply within a 24-hour window. Messages you start outside that window need pre-approved templates, and customers must have opted in. A properly built WhatsApp bot works within these rules from day one.
