Most Malaysian SMEs are already running their customer service on WhatsApp. Far fewer are running it on WhatsApp Business, and fewer still have filled in the parts that do the work for them. It is free, it takes an afternoon, and it is worth doing before you add any kind of automation on top — because automation amplifies whatever setup it inherits.
First: move off your personal number
If your business runs through your personal WhatsApp, you have a few problems stacked on top of each other. You cannot hand the account to staff without handing over your private messages. You cannot ever fully switch off. You cannot use business features. And when you eventually want to automate or add a second person, you have to migrate the number anyway — with all your customer history attached.
WhatsApp Business is a separate free app, and it can run on the same phone as your personal WhatsApp with a different number. Do this first. Everything else assumes it.
The profile fields people leave blank
Your business profile is the first thing a new customer sees, and it silently answers questions before they are asked. Fill in every field:
- Business hours — this is what drives the automatic “we’re away” behaviour later. Getting it right matters more than it looks.
- Address — with the map pin actually dropped, so customers can navigate rather than screenshot.
- Category and description — one clear line about what you sell, not a slogan.
- Website — even if it is a single page. It makes you findable and verifiable.
- Email — the channel corporate and bulk buyers will use when they need an invoice.
Every field you leave blank becomes a message somebody has to send you, and a reply somebody has to type.
The catalogue is doing more than you think
The catalogue is the single most under-used feature in WhatsApp Business, probably because building it feels like a chore. But it changes the shape of your conversations. Instead of typing prices repeatedly, you send an item. Instead of “do you have anything around RM100” turning into twenty messages, the customer browses.
A few things that make a catalogue actually work:
- Put the price in the price field, not just in the description. Customers filter on it.
- Use one clean photo per item on a plain background. Reused Instagram posts with text overlays look cluttered at catalogue size.
- Include the variants you actually stock — sizes, colours, pack quantities — as separate items if the price differs.
- Keep it small and current. Twenty accurate items beat eighty where half are out of stock.
Quick replies: your ten standard answers
Quick replies are saved messages you fire with a shortcut like /delivery. They are not automation — you still press the button — but they remove the retyping, and more importantly they force you to write your standard answers down properly, once.
Start with the questions you answer every single week: delivery rates and coverage, opening hours including public holidays, payment methods, location and parking, lead time, deposit and cancellation terms, return policy, bulk or corporate pricing.
Write each one as a complete answer, the way you would want a customer to receive it — specific numbers, no “it depends”. This list becomes the backbone of everything you automate later, so it is worth spending real time on.
The quality of your quick replies determines the quality of any assistant you layer on afterwards. Vague saved answers produce a vague assistant. Specific ones — “Klang Valley RM8, free above RM50, same-day dispatch before 3PM” — produce an assistant that answers the question so the customer can decide.
Labels, so nothing sits in limbo
Labels are how you stop treating your inbox as a to-do list you scroll. A workable set for most SMEs is small: New enquiry, Quoted, Awaiting payment, To deliver, Done. Five is enough. Twelve will not survive a busy week.
The value is not in the tidiness. It is that Quoted and Awaiting payment become a list you can work through on a slow afternoon — people who already told you they wanted to buy and then went quiet. That list is usually where the easiest money in the business is sitting.
Away and greeting messages, done properly
The default away message — “Thanks for your message, we will get back to you soon” — is worse than nothing. It tells the customer they have been received but not helped, which is precisely the moment they message your competitor.
Replace it with something that actually answers the question so the customer can decide: your hours, your delivery rates, your price range, and a link to your catalogue or website. Something like:
“Thanks for messaging! We’re closed now and reopen at 9AM. Quick answers while you wait — delivery: Klang Valley RM8, free above RM50. Payment: DuitNow, FPX, card. Catalogue below. Leave your question here and we’ll reply first thing.”
That message works overnight. The default one does not.
Then, and only then, automate
Once your profile is complete, your catalogue is accurate, and your ten standard answers are written down, automation becomes straightforward — because you have already done the thinking it depends on. An assistant is only as good as the business information behind it.
The gap an away message cannot close is that it is the same for everyone. It cannot answer “do you deliver to Seremban and how much”, tell one customer the price of the exact item they asked about, or pass a question it cannot answer to you with the conversation attached. That is the point where a real assistant earns its keep. But it earns it much faster on top of a WhatsApp Business account that has been set up properly.
What changes when you connect your existing WhatsApp Business app (Coexistence)
When you connect your existing number through Meta’s official Embedded Signup (Coexistence), you keep your number and keep using the WhatsApp Business app on your phone alongside your assistant. Before you connect, know the six things that change on the app:
- App version 2.24.17 or newer: Update the WhatsApp Business app on your primary phone before starting signup.
- Chat history sync (one-on-one chats only): Up to 6 months of existing 1-to-1 chats can sync during connection if you choose; group chats are not synced.
- Broadcast lists become read-only: Existing broadcast lists in the phone app can no longer send bulk blasts once connected.
- Linked companion devices log out once: Connecting logs out linked companion devices. You can re-link WhatsApp Web and WhatsApp for Mac afterwards, though WhatsApp for Windows cannot re-link on a coexistence number.
- Open the phone app at least once a week: Meta disconnects coexistence if the WhatsApp Business app on your primary phone is not opened for approximately 14 days.
- Replies you type in the app stay free: Messages you type yourself inside the WhatsApp Business app do not count towards Meta’s per-reply API charges.
- It answers on your own WhatsApp Business number, and you keep using the WhatsApp Business app on your phone.
- It answers only from facts you have approved: prices, hours, stock notes, delivery, and how to book or order.
- Anything else, such as a discount, a booking date, a complaint or a question it has no fact for, is handed to you with the conversation. It tells the customer so instead of guessing.
- You can start with a 14-day assisted pilot, no card needed.
