Why WhatsApp works for selling
If your buyers are on WhatsApp all day, a message there gets read. An email might sit until Friday, which is why so many small businesses now take most of their enquiries in the chat.
It also brings three problems email never had. Chats are mixed in with family and friends. Deals vanish up long threads. And a message someone didn't expect feels far more intrusive on their phone than in their inbox.
This guide covers the selling side: what to send, when, and how to keep track. For the difference between the free app and the paid platform in detail, What is WhatsApp Business? goes through both.
Pick the right version
There are three ways to sell on WhatsApp, and most sellers only need the first two.
| Version | Who it suits | What it costs |
|---|---|---|
| Your personal WhatsApp | Almost nobody, for selling | Nothing, but work and family share one list |
| WhatsApp Business app | One seller or a small team replying to enquiries and following up | Free to download |
| WhatsApp Business Platform (API) | Businesses sending at scale through software | Charged per message by Meta, plus the vendor's fee |
The Business app is the usual starting point, and WhatsApp's own guide says it's free to download. Its features page lists what it adds: a business profile with your hours and website, an automatic greeting for new chats, away messages outside your hours, quick replies and labels.
The platform is charged differently. WhatsApp's platform pricing page says businesses pay per message delivered, with rates set by the recipient's market and the message category. When someone messages you, a 24-hour window opens for your service replies, and each new message from them resets it. Since 1 October 2026, Meta's developer page says those replies are free for the first 1,000 a month per number and charged after that.
For most sellers, that means one thing: replying is cheap and easy, and starting conversations with strangers at scale is the part that costs money and carries rules.
Get people to message you first
The best WhatsApp sales chats start with the buyer. They tap a button, say hi, and you're talking to someone who asked.
Make that easy wherever buyers find you:
- A click-to-chat link on your website, email signature and social profiles. The WhatsApp link generator makes one with a QR code and a message already typed.
- The QR code on your business card, quote PDFs and shop counter.
- "Message us on WhatsApp" in your ads, instead of a form they have to fill in.
A pre-filled message helps you as much as them. "Hi, I saw the kitchen quote page and want to ask about timing" tells you where they came from before you've said a word.
Write the first reply
Your first reply should answer them, then ask one question that moves things forward. Don't send a brochure.
Hi [name], thanks for getting in touch. I'm [you] from [business].
[Answer their question in one or two lines.]
So I can give you something useful: [one question, e.g. "roughly when are you hoping to start?"]
Then set up the Business app's greeting and away messages, so nobody gets silence. The away message should say when a person will reply, and then someone should.
Speed matters more on WhatsApp than anywhere else, because buyers can see you've read the message. If enquiries come in at night or while you're in meetings, answering leads at night covers how to reply first from your own number.
Follow up without being a nuisance
Most WhatsApp deals die quietly. The buyer got busy, nobody wrote back, and a week later the chat has scrolled out of sight.
A few rules keep follow-ups welcome:
- End every chat with a next step and a date. "I'll send the two options by Thursday" gives you a reason to write on Thursday.
- Follow up with something new: the quote, an answer to their question, a photo of similar work. "Just checking in" gives them nothing to reply to.
- Two or three follow-ups over two weeks is plenty. After that, ask plainly whether to close the file.
- Use labels in the app for the stage each chat is at, like "new", "quote sent" and "follow up". Then filter by label each morning.
Hi [name], I haven't heard back about the [thing], so I'll assume the timing's not right. Shall I close this off for now, or check in again in a month?
You'll be surprised how often that one gets an answer, because it asks a question people can reply to in a word.
Broadcasts: only to people who said yes
Sending one message to many buyers is where WhatsApp selling goes wrong. On the phone, an unwanted promo feels like a stranger walking into your living room.
Meta is clear about permission for the platform. Its opt-in guide says businesses must get opt-in before messaging people, must say clearly that the person is opting in, and must name the business they'll hear from. The same page notes that people can block or report a business, and that businesses with low quality for a sustained period get rate-limited.
Treat those as good manners for the app too:
- Ask before you add someone to a list. "Can I send you our quarterly price updates here?" is enough.
- Send only what they asked for.
- Personalise it. A broadcast with their name and a line about their last purchase reads like it was written for them.
- Tell them how to stop, and honour it the same day.
ActivityTracker's broadcasts send from your own number with each client's name in, one message at a time in the hours you choose, and show who wrote back.
Keep every chat on the client's record
The Business app keeps chats tidy. It doesn't remember for you. In three months, what did that buyer say about their budget? It's up the thread somewhere.
Keep a record per buyer outside the chat: what they want, what you've sent, what's next and when. That can be a spreadsheet at first. Once you have more than 30 or 40 live conversations, it's CRM territory, and a CRM that pulls in the WhatsApp chat saves the copying.
Made-up example: a two-person kitchen renovation business gets about 20 WhatsApp enquiries a week from its ads and website.
Monday: 6 new chats came in over the weekend, and the greeting message told each of them someone would reply by 10am Monday. Dan answers all 6 by 9:40, each with one question about when they want to start.
Tuesday: 4 of the 6 write back. He books 2 site visits, sends rough prices to the other 2 and labels those chats "quote sent".
Wednesday: he filters by "follow up" and finds 5 chats from last week that went quiet. He sends each one something new, like a photo of a similar kitchen or an answer to a question they'd asked. 2 reply.
Thursday: his partner Mei takes the site visits, but the chats are on Dan's phone. She asks him for the notes on one buyer, and he scrolls for ten minutes to find what they'd said about the budget.
Friday: they count the week: 20 enquiries, 16 answered within two hours, 4 site visits, 1 signed. The count is fine. The Thursday scramble is the problem, so they decide the notes need to live somewhere both of them can see.
When a team shares the selling
One person, one number, one phone works. Two people sharing one phone doesn't, for long.
Here are the usual options, from simplest to most involved.
- Each seller keeps their own business number and their own chats, and the team agrees on who handles which buyer.
- A shared inbox where every number shows up in one place, and chats can be assigned to whoever's handling that buyer.
- The platform, through a vendor, when you need many people on one number or messages sent by software at scale.
Most small teams are best served by the second. Whichever you choose, write down who owns each buyer, so nobody gets two different answers from the same business.
When more than one person sells on WhatsApp, ActivityTracker's team inbox puts every number you use in one place, shows who's waiting, lets you assign a chat to a teammate, and lands every chat on the client's record.
What to do first
- Move selling chats to the Business app on a work number.
- Fill in the profile, and set a greeting, an away message and three quick replies.
- Add labels for "new", "quote sent" and "follow up", and filter by them every morning.
- Put a click-to-chat link everywhere a buyer might find you.
- Start a simple record per buyer with the next step and its date.
