WhatsApp Business Enquiries: Keep Them From Going Cold
WhatsApp business enquiries are the cheapest ones a shop collects, and the easiest to lose. The number is on the signboard, the pamphlet and the contact page, and customers tap it. Whether that tap becomes a sale depends on everything after it: who actually sees the chat, how fast someone answers, and what happens to a message that arrives at 9pm. HubSpot’s research on buyer response expectations, updated 24 March 2025, puts a number on the patience involved: 82% of consumers rate an immediate response as important or very important for marketing and sales questions, and nearly two-thirds expect one within ten minutes.
The setup below is the one we run on every enquiry path: a prefill that carries intent, an owner for the number, the 24-hour window treated as a workflow, and an after-hours answer that fires before a human reads the chat. From 1 October 2026 it also carries a price tag, and that date changes the routine for shops that never think about WhatsApp’s plumbing.
A prefill that carries intent
Both consumer sites we built lead with a WhatsApp button rather than a form alone, and the reason is the first message. On warasat.com.pk the button opens a chat with the first half-sentence already typed: “Hi Warasat, I would like to ask about”. The visitor finishes the thought, so the enquiry arrives carrying its own intent. The diagnostic centre at mtufaildiagnosticcenter.com puts a Book via WhatsApp button next to the form’s submit button, and its prefilled text already says what the patient wants: an appointment at the centre.
A click-to-chat link is a plain URL with the message encoded into it, using our own business number as the example:
https://wa.me/923704604266?text=Hi%2C%20I%20have%20a%20question%20about%20your%20servicesOne tap and the customer never faces an empty text box. WhatsApp documents the format on its click-to-chat help page. The empty box is worth engineering away: a bare “Hi” starts a conversation with no content, and whoever is behind the counter spends the next four messages working out what the customer wants.
Where WhatsApp business enquiries go cold
Enquiries are a queue, and queues need an owner. The free WhatsApp Business app covers most shops and clinics: it costs nothing to download, it gives you a business profile with opening hours, and it carries quick replies and labels for the questions you answer daily. What it does not give you is routing. Messages land in one chat list on the phone and the computers linked to that number, so whoever holds the phone owns the queue.
We hold our own number to a written standard because of this: an enquiry counts as handled once it has an owner and a drafted answer, not when it has been glanced at. A chat list rewards glancing. If several people need to work one number, the app runs out and the WhatsApp Business Platform becomes the conversation, which is now also a billing decision, not only a technical one.
The 24-hour window is the workflow
WhatsApp’s own rules draw the working day for you. When a customer messages, a 24-hour customer service window opens; inside it you reply free-form, and once it closes only approved template messages reach that customer. Meta’s pricing documentation, updated 10 September 2026, walks the exact sequence: a template sent at hour 30, six hours after the window closed at hour 26, is a charged message, and the customer’s reply to it reopens the window for normal conversation.
Read the window as an operations rule rather than a billing rule. A shop that answers inside the day lives on the free side of it. The failure mode is the follow-up: “is tomorrow still good for the appointment?” typed the next afternoon, after the window closed, needs a template instead of a chat message. Businesses that run on follow-ups end up on the platform for that reason alone.
From 1 October 2026, the replies cost money
The replies inside the window stop being free on 1 October 2026. Meta’s pricing update page, last updated 25 August 2026, sets out the change: service messages, the free-form replies you send inside the 24-hour window, become charged per message after a year and a half of being free, and utility templates sent in response to a customer, the confirmations and receipts, become charged from the same date. Rates vary by the recipient’s country and, for templates, by category.
Two deadlines sit around it. A business onboarded through a solution provider needs a payment method on file by 30 September 2026, or service message delivery stops. And an AI assistant bolted onto WhatsApp through a third-party tool now means two charges: the tool’s own AI cost and Meta’s delivery charge. None of this makes WhatsApp expensive at shop volumes. It makes it a line to budget, like the phone bill, and a reason to keep the conversation moving inside the window instead of letting it lapse into template territory.
The checklist we run on every enquiry number
The setup compresses into five rows, and the last one is the row everyone skips.
| Row | What we set | Why it exists |
|---|---|---|
| Owner | One named person who holds the number and answers for it | A chat list with no owner is where enquiries go cold |
| First reply | A saved quick reply that confirms arrival and names who answers next | Ten minutes is the reply window nearly two-thirds of buyers expect |
| Prefill | Every wa.me button opens with a question that carries intent | An empty “Hi” makes the shop play twenty questions |
| Record | The enquiry written into a log with a name against it | A chat scroll is not a record you can work from tomorrow |
| After hours | An away message with true opening hours and the emergency path | The 9pm message answered at 9pm, even by a bot, beats the same message answered at 10am |
The after-hours row is the cheapest to set: the away message field in the Business app takes ten minutes to fill, and it answers the 9pm message at 9pm. If the enquiry needs a structured record, the button sits next to a form rather than replacing it; we weighed that trade-off field by field in our piece on contact form fields.
When the free app stops being enough
Volume ends the free app before features do. Meta caps how many unique customer numbers a business can message in a rolling 24 hours outside the window, and a new portfolio starts at 250; the messaging limits documentation, updated 21 May 2026, shows the ladder to 2,000, then 10,000 and beyond, with automatic scaling that demands high message quality and real use of the current limit. 250 is generous for a clinic and tight for a recruitment agency.
Our advice to clients stays blunt: do not buy the platform for volume you do not have. It earns its cost when several people must work one number, when enquiries should land in other software automatically, or when an assistant should answer before a human reads the chat. Where the driver is a pile of repeated questions, the next rung is an agent, and we documented where an agent hands back to a human in our piece on AI agent phone answering.
Give every enquiry somewhere to land
Three checks, tonight: message your own number from a second phone and watch who sees it; fill the away message with hours that are true; prefill the button with a question that carries intent. The 9pm message is the test of the whole setup, because that is the one that either gets an answer or becomes another shop’s sale.
If the enquiry path on your site needs the same treatment, a prefill that carries intent, a window-aware reply routine and an after-hours answer, that is part of how we run web development projects. The contact page is the fastest way to start the conversation, and the prefilled message is optional.
FAQ
Is the WhatsApp Business app enough, or do I need the API?
For a shop or clinic answering a handful of enquiries a day from one phone, the free app is enough: business profile, quick replies, labels, away messages. The platform earns its cost when several people need to work the same number, when enquiries must land in other software, or when automation should answer before a human does. Volume matters too: business-initiated messaging starts at 250 unique customers per rolling 24 hours, which a busy agency can outgrow.
What is the WhatsApp 24-hour window?
When a customer messages you, a 24-hour customer service window opens. Inside it you reply free-form. Once it closes, only approved template messages can reach that customer, and templates are charged, though the customer’s reply to one reopens the window. Treat the window as the deadline for a conversation: the follow-up you want to send the next afternoon needs a template, not a typed message.
Does replying to customers on WhatsApp cost money?
From 1 October 2026, yes. Meta charges per message for service messages, the replies inside the window, and for utility templates sent in response to a customer; both were free until that date. Rates vary by the recipient’s country and, for templates, by category. A shop answering enquiries inside the window pays for replies that used to cost nothing, which is a reason to answer efficiently, not to leave the channel.
Should a WhatsApp button replace the contact form?
Rarely entirely. A prefilled chat link wins on speed for someone holding a phone with one thumb free, and both consumer sites we built keep one next to the form. The form still earns its place when you need a structured record, routing to different staff, or details collected before anyone replies. Run both: the button for intent, the form for the paper trail.
