For many small businesses, especially where WhatsApp is everyone's default messaging app, it isn't one channel among several. It's the channel. People will message a business on WhatsApp who would never fill in a contact form or send an email.
The problem is the other side of that: the messages don't stop at closing time. Here's how to make WhatsApp work for the business without it running your life.
Should you use WhatsApp Business or your personal account?
The free WhatsApp Business app is a different app from the one you already have, and it's worth the twenty minutes to switch.
What you get that the normal app doesn't have:
- A business profile — address, hours, a short description, a link to your website. Customers can open it by tapping your business name at the top of the chat, before they've typed anything, which answers the basic questions — when you're open, where you are — before people have to ask.
- A greeting message that sends automatically to anyone messaging you for the first time.
- An away message for outside your working hours.
- Quick replies — saved answers you insert with a shortcut instead of retyping. If you've typed your price list more than five times, save it.
- Labels (WhatsApp is gradually renaming these "lists") — mark a chat "new enquiry", "quoted", "booked", so your chat list becomes something like a customer list.
You can run it on a second number, which is the cleanest way to keep work off your personal phone.
What should your away message say?
Most away messages say "We are currently unavailable. We will respond shortly." That tells the customer nothing and sets up a promise you might not keep.
A better one answers the question they were going to ask, and sets a real expectation:
Thanks for messaging [business]! We're closed right now — open [your hours]. Most enquiries are about [the two things people actually ask]: [short answer]. We'll reply when we open.
The point is that someone messaging at 10pm gets something useful at 10pm, instead of a reply that says you'll reply. (The away message is sent from your phone, so it only goes out while the phone is on and connected to the internet — silence it at night, don't switch it off.)
How do you put a WhatsApp link on your website?
Not a phone number people have to copy. A link that opens a chat with you, with the first message already typed.
The format is https://wa.me/XXXXXXXXXXXX — your number with the country code, no plus sign, no spaces. Add ?text= and a message to prefill one:
https://wa.me/XXXXXXXXXXXX?text=Hi,%20I%20saw%20your%20website
Our free WhatsApp link generator builds the link for you, with a QR code for your shop, menu or card.
The prefilled message matters more than it looks. A lot of people open the chat, see an empty box, don't know what to write, and leave. Giving them the first line removes that hesitation — and it tells you where the enquiry came from.
When should the phone be off?
This is the part that isn't about software.
Set your hours in WhatsApp Business, turn the away message on, and then actually don't answer outside them. If you reply at 11pm once, customers learn that 11pm works, and the away message stops meaning anything.
Answering fast during working hours matters enormously — a quick reply often decides who gets the job. Answering at midnight does not win you that job. It just moves the same job to a worse hour.
When is WhatsApp automation worth it?
Once you're answering the same five questions every day, quick replies stop being enough: they're saved answers you still have to send yourself.
That's the point where an AI assistant on your WhatsApp Business number earns its keep (ours runs on Meta's WhatsApp Cloud API rather than the free Business app, so your number has to be connected to the Cloud API first; we set it up with you on enquiry). It can answer from your actual details — your services, your hours, your policies — at 11pm, and if a reply would state a price, refund term or turnaround time that isn't in the facts you've entered, it leaves that out; when nothing useful is left, it tells the customer the team will get back to them. It doesn't notify you when that happens. Ours can also connect to your Google Calendar, check which slots are free within your working hours and book the appointment, so a straightforward booking can be completed in the chat instead of waiting for you. More on how it works in WhatsApp AI agents for small business.
But that's step three, not step one. Get the Business app, write a real away message, put a proper link on your site. Those three cost nothing and solve most of the problem.
If you're still drowning after that, automation is the answer — and you'll know exactly which questions to hand over, because you'll have answered them a hundred times.
