Orders, photos, voice notes, payment links — it works, and I wouldn't tell anyone to stop.
But think about what happens before the first message. Someone gets your number from a friend. Before they type anything, most people do one quiet thing: they search your business name.
What do they find? Nothing at all, or an old directory entry with a different address, or a page someone set up once and forgot. That's the moment a stranger decides whether you're real — and it happens before you even know they exist.
WhatsApp is where the conversation happens. It's not where the decision happens.
The fix doesn't have to be a big project. One clear page: your name, what you do, where you are, working contact details, the padlock in the browser bar, and a button that opens WhatsApp. A front door that matches the shop behind it.
If you already have a page like that, it's worth knowing what a first-time searcher actually sees. That's the check I do at https://TechBiz.ae.
