WhatsApp is the channel customers already use to talk to their family, their landlord and their plumber. That is the advantage and the risk. A message from a business arrives in the same place as a message from a friend, and it is judged by the same standard.
Used as a conversation, it works better than almost any other channel for local businesses. Used as a broadcast billboard, it gets blocked quickly and permanently.
Set up the business profile properly
Use the business app rather than your personal number. Fill in the name exactly as it appears on the shopfront, the category, the address, the opening hours and a website link. Add a logo that is recognisable at small size.
Load your catalogue if you sell products: photographs, names and prices, with a short description. A customer who asks what you have can then be sent one link instead of six photos taken under poor light.
Set an away message for closing time and a greeting for first contact. Both should say when someone will reply, not simply that nobody is available.
Collect permission, then keep it
Only message people who have agreed to hear from you, and record how they agreed. The simplest method is at the point of sale: would you like updates about deliveries on this number? A tick on a form, a reply to a confirmation message, a QR code that opens a chat with a prepared greeting.
Keep the record simple. A note in the customer record with the date and the words used is enough for a small business. If someone says stop, stop the same day and note it.
Permission is not a legal formality. It is the difference between a message someone reads and a number someone blocks.
Send the messages people want
Four kinds of message earn their place. Order and delivery updates. Appointment reminders with a way to reschedule. Availability of something a customer asked about. And answers to questions, in a thread, like a human.
Each should be short, specific and useful without a click. If a message exists mainly to remind someone you are still trading, it belongs on a channel people chose to browse, not in a private chat.
What to avoid
Do not add every customer to a broadcast list. Do not forward the same image to two hundred people. Do not send a daily offer because the tool makes it easy. And do not use a group chat as a mailing list; a group notifies everyone, including the people who never asked to be there.
Voice notes can be effective for an explanation and irritating at scale. If you use one, keep it under thirty seconds and only in a one-to-one conversation.
Know the difference between lists, groups and the API
A broadcast list sends to recipients individually and only reaches people who saved your number. A group is a shared chat with notifications for everyone. The business API is for larger operations and requires approved message templates for business-initiated contact, with rules about what can be sent outside a customer service window.
If you are sending order updates to hundreds of customers, the API is the right tool. If you are a two-person shop answering enquiries, the business app is enough and costs nothing to try.
Measure replies, not sends
The useful numbers are replies, questions answered, orders placed and blocks. A broadcast that reaches five hundred people and produces no replies is a failure even if the delivery report looks impressive.
Ask new customers where they found you, and note when the answer is WhatsApp. Add a line to your enquiry sheet. After a month you will know whether the channel is producing work or just activity.
Remove people who have not interacted in six months, and thank them for their time. A smaller list of people who read and reply is more valuable than a large one that generates silence, and it protects the number you send from.
The WhatsApp setup checklist
- Business app installed on a number the business controls.
- Name, category, address, hours and website completed.
- Catalogue loaded with clear photographs and prices.
- Greeting and away messages written with a reply time.
- Quick replies saved for the ten most common questions.
- A consent method in place at the counter and at checkout.
- Permission recorded with a date for every contact.
- A written rule about what will and will not be sent.
- A quarterly review of replies, blocks and inactive contacts.
The messages that work on WhatsApp are the ones you would say across the counter: your order is ready, we have the part, can you come in on Thursday. Keep that tone and the channel will keep working. Turn it into advertising and it will close.
