What to set up
- Use the free WhatsApp Business app with a full business profile.
- Add a fixed WhatsApp button and one next to every service.
- Use pre-filled messages so you know which page the client came from.
- Prepare quick replies and an away message.
- Keep a contact form for detailed enquiries.
Conclusion
WhatsApp doesn't replace your website — it completes it. The website convinces, WhatsApp closes.
