TL;DR — WhatsApp Business API pricing for Singapore, up front
- The free WhatsApp Business app and the paid WhatsApp Business API are different products. The app costs nothing and runs on one phone. The API has no licence fee from Meta but is billed per message delivered, by category and by the customer's country.
- Singapore rates on Meta's card effective Oct 1 2026: marketing USD 0.0732 (S$0.0937) per message; utility, authentication and service USD 0.0160 (S$0.0205) per message.
- Since Oct 1 2026 even replies are metered. Each business number gets 1,000 free service messages a month; the 1,001st is charged at the utility rate. Utility templates inside the 24-hour window are no longer free either.
- Providers add their own fee on top: from roughly USD 0.005 per message (Twilio) to roughly USD 50–350 a month in platform subscriptions (Wati, respond.io, SleekFlow), some with a markup on Meta's rates. Going direct to Meta's Cloud API has no platform fee but needs a developer.
- Worked totals below: at a typical SME mix, Meta's bill is roughly S$53 at 1,000 messages, S$551 at 10,000 and S$2,835 at 50,000 a month, before provider fees.
Every WhatsApp conversation we scope in Singapore starts with the same confusion. "WhatsApp Business is free, right?" Yes, if you mean the app on your phone. No, if you mean the API that lets a chatbot, CRM or broadcast tool send messages for you. WhatsApp Business API pricing is per message, varies by message type and the customer's country, and since Oct 1 2026 also covers the replies your team sends inside a live chat. This guide puts the Singapore numbers in one place, in SGD and USD, then stacks provider fees on top so you can budget a real monthly figure.
One disclosure before the numbers. Finyki builds AI chatbots and workflow automations on the WhatsApp Business API; we are not a solution provider, do not resell message credits and earn no margin on any platform below, so we can list Twilio, respond.io, Wati, SleekFlow and AiSensy side by side without a favourite. Our commercial interest is the build on top, covered honestly at the end.
WhatsApp Business app vs WhatsApp Business API: which one costs money
There are three ways to be on WhatsApp, and the WhatsApp Business price depends entirely on which one you mean.
- WhatsApp Business app. Free. One number, manual replies, basic catalogue, quick replies and labels. Often enough for a two-person shop.
- WhatsApp Business Platform (the API). WhatsApp Business Platform pricing has no account fee from Meta, but every delivered message is metered. This is what chatbots, broadcasts to thousands of opted-in contacts, shared inboxes and CRM integration need. The WhatsApp Business account price here is your monthly message bill plus whatever provider you use to reach the API.
- A WhatsApp Business Solution Provider (BSP) product. A SaaS inbox, broadcast or chatbot tool built on the API. You pay the provider's subscription or per-message fee, with Meta's fees passed through on top, sometimes marked up.
So "is WhatsApp Business free?" has a precise answer, and it is the whole of WhatsApp Business pricing in one line: the app is free, the API is pay-per-message with no base fee, and the tooling around the API is where the subscriptions live. The rest of this post is about the second and third.
How WhatsApp Business API pricing works since Oct 1 2026
Meta moved from conversation-based to per-message pricing on July 1 2025: you now pay for each template message delivered, with the rate set by message category and the country code of the customer's number. A +65 number pays Singapore's rate; a +60 number pays Malaysia's.
The four message categories
- Marketing. Promotions, offers, re-engagement. The most expensive category, and where broadcasts live.
- Utility. Order confirmations, delivery updates, appointment reminders, account alerts.
- Authentication. One-time passcodes. Same rate as utility in Singapore.
- Service. Free-form replies your team or bot sends inside the 24-hour window that opens when a customer messages you. The category that changed.
What changed on Oct 1 2026
Until Sept 30 2026, service messages were free and unlimited, as were utility templates inside an open 24-hour window. From Oct 1 2026, per Meta's published update:
- Every business phone number gets 1,000 free service messages per month. The allowance resets monthly and does not roll over.
- From the 1,001st service message, each one is charged at the same per-message rate as utility and authentication in that market. There are no volume tiers for service messages.
- Utility templates sent inside the 24-hour window are now charged at the utility rate, not free.
- Messages inside the free entry point window from Click-to-WhatsApp ads or a Facebook Page button stay free for delivery, and that window is now longer (see the table below).
- Accounts with no payment method on file by Sept 30 2026 had service delivery stopped. If your bot went quiet last week, check billing before the code.
Why this matters more for support bots than for marketing bots
A marketing broadcast was always metered, so Oct 1 changed little for it. A support chatbot is mostly service messages. For example, a number handling 3,000 inbound chats a month with three bot turns each sends roughly 9,000 service messages, 8,000 of them billable: about S$164 a month that did not exist in September. Not ruinous, but it scales with how chatty the bot is, which is why we design bots to answer in fewer, fuller turns.
WhatsApp Business API pricing in Singapore: the rate card in SGD and USD
This is the WhatsApp Business API pricing Singapore businesses pay Meta from Oct 1 2026, as published by Meta and mirrored on its solution providers' Singapore rate pages, which we read on Oct 8 2026. Singapore is listed as its own market, not under "Rest of Asia Pacific", and Meta adjusted rates during 2026, so treat this as a dated snapshot and confirm the current card before you budget. The SGD figures are what Meta bills accounts invoiced in Singapore dollars; a USD-billed account pays its bank's exchange rate instead. Add 9% GST: Meta's invoices to Singapore businesses exclude it, and a GST-registered company accounts for it under reverse charge; confirm with your accountant.
| Message category | USD per message | SGD per message | When it applies |
|---|---|---|---|
| Marketing | 0.0732 | S$0.0937 | Every delivered marketing template, no free allowance |
| Utility | 0.0160 | S$0.0205 | Every delivered utility template, including inside the 24-hour window since Oct 1 2026 |
| Authentication | 0.0160 | S$0.0205 | Every delivered OTP template |
| Service | 0.0160 | S$0.0205 | Replies inside the 24-hour window, after the first 1,000 per number per month |
| Free entry point | 0 | 0 | From Click-to-WhatsApp ads or a Page button; up to 7 days since late Sept 2026 (72 hours before), confirm on Meta's card |
Three things to read off that table. Marketing is about four and a half times the price of everything else, so your traffic mix matters more than raw volume. Each recipient is billed at their own country's rate, so Malaysian or Indonesian customers change the blended figure. And Meta's volume discounts for utility and authentication begin at monthly volumes from the hundreds of thousands to the tens of millions, depending on category; an SME sending 50,000 a month is on the base rate.
What a WhatsApp Business API provider adds on top, with worked monthly totals
You reach the API either directly through Meta's Cloud API, which has no platform fee, or through a WhatsApp Business API provider. The WhatsApp API cost you actually pay is Meta's per-message bill plus the provider's layer; that sum is the real WhatsApp Business API cost, and no pricing page shows both halves. Here is how the common options charged on their public pages at the time of writing; check the current page before you commit.
- Meta Cloud API direct. No platform fee. You pay Meta's rates and nothing else, but you need a developer to build and host the integration and inbox.
- Twilio. USD 0.005 per message, inbound or outbound, on top of Meta's fees. No subscription, no inbox; developer-oriented.
- respond.io. Starter USD 79, Growth USD 159, Advanced USD 279 a month on annual billing (about 25% more monthly), 5–10 users included, priced by monthly active contacts. States that Meta's fees pass through with no markup.
- Wati. Growth, Pro and Business tiers, 3–5 users included. Wati shows region-specific prices; the USD figures seen in Oct 2026 ran about USD 49–69, 99–149 and 249–349 a month by billing cycle and region, and the totals below use the annual-billing figures from October 2026 roundups (USD 59, 119 and 279). Third-party reads report a markup on Meta's rates on the lower tiers, so get Wati's Singapore card in writing.
- SleekFlow. Hong Kong-founded, with a Singapore HQ; entry paid tiers have sat around USD 119–149 a month depending on billing cycle, priced by contacts, and its published Singapore rates sit about 15% above Meta's. Check the current page, which changes often.
- AiSensy. Priced in Indian rupees, entry plans in the low tens of US dollars a month plus chatbot and AI-agent add-ons. Cheap on paper; check its Singapore rate card and support coverage first.
Now the totals. We assume a typical SME mix of 50% marketing, 30% utility and 20% service, all to Singapore numbers, with the 1,000 free service messages applied; a support-only bot comes in far lower, a broadcast-only account far higher. Provider fees are the annual-billing tier that fits the volume (for Wati, the roundup figures above), converted at roughly USD 1 = SGD 1.27 for illustration.
| Monthly volume (mix 50/30/20) | Meta fees | + Twilio (outbound only; inbound adds USD 0.005 each) | + respond.io | + Wati | + Cloud API direct |
|---|---|---|---|---|---|
| 1,000 messages 500 marketing, 300 utility, 200 service (all free) | USD 41 / about S$53 | + USD 5 → about S$59 | + USD 79 → about S$153 | + USD 59 → about S$127 (before any markup) | + USD 0 → about S$53 plus your own hosting and dev time |
| 10,000 messages 5,000 marketing, 3,000 utility, 2,000 service (1,000 free) | USD 430 / about S$551 | + USD 50 → about S$614 | + USD 159 → about S$753 | + USD 119 → about S$697 (before any markup) | + USD 0 → about S$551 plus hosting and dev time |
| 50,000 messages 25,000 marketing, 15,000 utility, 10,000 service (1,000 free) | USD 2,214 / about S$2,835 | + USD 250 → about S$3,152 | + USD 279 → about S$3,189 (priced by active contacts, so the real figure at this volume is likely above the Advanced tier) | + USD 279 → about S$3,166 (before any markup) | + USD 0 → about S$2,835 plus hosting and dev time |
The pattern is obvious. Below about 10,000 messages a month the provider subscription is a large share of the bill, so a cheap tier or a per-message provider like Twilio wins. Above 50,000, Meta's marketing fees dominate; what matters then is whether the provider adds a markup, charges for inbound, and bills contacts or users. At 50,000 messages a 20% markup on Meta's rates costs more than the subscription itself.
"At small volumes you are buying a provider. At large volumes you are buying Meta's rate card and the provider is a rounding error. Price the mix, not the message."
Can I use WhatsApp Business API for free?
Partly, and the free parts shape how you should design the channel.
- No licence or setup fee from Meta. Creating a WhatsApp Business Account, verifying it and connecting a number to the Cloud API costs nothing; some providers charge onboarding, Meta does not.
- 1,000 service messages per number per month are free. A low-volume support line that answers inbound questions in few turns can stay inside that allowance indefinitely.
- Conversations started from Click-to-WhatsApp ads or a Facebook Page button are free to message in for the entry point window, reported as up to 7 days since late Sept 2026. You paid for the ad instead.
- Inbound messages from customers are free from Meta. Only your outbound delivered messages are metered. Note that Twilio charges its USD 0.005 on inbound too.
Never free: any marketing, utility or authentication template, and any service message past the monthly thousand. If someone sells you "free WhatsApp API", they either fold Meta's fees into a subscription or mean the Cloud API has no platform fee. Know which.
How can I send 10,000 messages on WhatsApp?
The honest answer has three parts: the right product, the right permission, and the right sending limit.
The product is the API, not the app. The app's broadcast list caps out at a few hundred contacts who must have you saved, and bulk promotion from an app number gets it banned. Ten thousand messages means templates on the Business Platform, through a provider or direct.
The permission is opt-in. Meta requires it, and Singapore's PDPA requires consent for marketing messages too. Buying a list and blasting it gets templates rejected, your quality rating downgraded and, at worst, the number restricted. Collect opt-ins on your website, at checkout and in your ads, and keep the record.
The limit is Meta's messaging tier. Meta caps the unique customers you can message in 24 hours, per business portfolio and shared by all its numbers: 250 for a new portfolio, 2,000 once verified, then 10,000, 100,000 and unlimited through automatic scaling as you send consistently with a healthy quality rating. In our experience a verified portfolio warmed up over two to three weeks typically reaches the 10,000-a-day tier; one that tries it on day one gets throttled. And at Singapore's marketing rate, 10,000 marketing messages cost about S$937 from Meta before provider fees, so send to the 2,000 likely to buy, not the 10,000 you have.
Is WhatsApp API cheap?
Compared with what? Three honest comparisons of the WhatsApp Business API cost.
Against SMS, roughly a wash on marketing and cheaper on everything else. A Singapore utility message at S$0.0205 undercuts most A2P SMS rates to Singapore numbers; a marketing message at S$0.0937 sits in the same band as SMS or a little above, but carries images, buttons and a reply thread. We pick WhatsApp over SMS not on price but because Singaporean customers reply on it.
Against a human reply, absurdly cheap. A service message costs about two cents. If a support agent costs you S$25 an hour fully loaded and handles ten chats an hour, the human reply is a hundred times the message fee. Your support cost lives in the staffing behind the inbox, not in the WhatsApp bill.
Against a careless setup, expensive. The overspends are predictable: marketing content in a utility template until Meta recategorises it, unsegmented broadcasts, a bot sending three bubbles where one would do, and an unnoticed provider markup. Fix those and WhatsApp is one of the cheapest channels an SME can run.
How much do WhatsApp Business ads cost?
"WhatsApp Business ads" means Click-to-WhatsApp ads: Facebook or Instagram ads whose call to action opens a chat with your number. They are bought in Meta Ads Manager at auction, so there is no fixed rate; cost per conversation started depends on audience, creative and competition that week. In our experience Singapore SME campaigns land anywhere from a few dollars to well over ten per started conversation, and the only useful number is the one in your own Ads Manager after a week of spend.
The part people miss: the conversation the ad opens is free to message in for the entry point window, so the ad budget also buys free messages per lead. That suits a qualification bot that asks three questions and books a call, not collecting numbers to blast marketing templates later, which are metered at the marketing rate however the contact arrived.
How to choose a WhatsApp Business API provider in Singapore
No provider listicle here; our guide to the best AI chatbot companies in Singapore covers the platforms, including SleekFlow, in depth. On cost, provider choice comes down to one question: what is your volume, and who will operate it?
| Your situation | Reasonable route | Why on cost |
|---|---|---|
| Under 2,000 messages a month, a human team replies | Entry tier of an inbox tool (Wati Growth, respond.io Starter, SleekFlow entry) or the free app if one phone is enough | Subscription is the whole bill; buy the cheapest inbox your team will actually use |
| 2,000–20,000 messages a month, mix of broadcasts and support | Mid tier of an inbox tool with a no-markup pass-through of Meta fees | Meta fees now exceed the subscription; a markup starts to matter more than the tier price |
| Over 20,000 messages a month, or a chatbot doing most of the replying | Twilio or Cloud API direct, with a built inbox and bot on top | At this volume the platform fee is noise and the markup is the cost; owning the integration removes both |
| Mostly OTPs and transactional alerts from your own system | Twilio or Cloud API direct | Pure per-message, no inbox needed, utility rate is the cheapest line on the card |
| You want WhatsApp wired into your CRM, calendar and finance tools | Any of the above plus an automation layer | The orchestration matters more than the provider. See our n8n vs Zapier vs Make comparison and our workflow automation service |
Two checks before signing with any WhatsApp Business solution provider. Get their Singapore rate card in writing and compare it line by line with Meta's; several platforms, including Wati and SleekFlow, apply a markup, which is legitimate but should be visible. And ask who owns the number and the WhatsApp Business Account; some platforms register it under their own business manager, which turns leaving into a migration.
What it costs to put a chatbot on the API
This is our lane, so here is the straight version. Meta's and the provider's fees are the channel's running cost. The chatbot or automation that decides what gets sent is a separate one-off cost, usually the bigger number in year one: our published range for a single-channel chatbot build is SGD 8k–35k, higher for multi-channel systems; the breakdown is in our guide to what AI automation costs in Singapore and on our pricing page.
Whether that beats a self-serve platform's built-in bot depends on three things: whether the bot must read from your own systems (orders, bookings, policy documents), whether it must hand off to humans with context, and whether the message mix is heavy enough that fewer, better turns save real money under the Oct 1 rules. A ten-person clinic answering FAQs does not need us; the platform bot and the free 1,000 service messages will do. A distributor fielding 5,000 order-status chats a month that each take a human four minutes probably does, and the saving is in headcount. When leads arrive on WhatsApp and need qualifying, routing and follow-up, that is a sales automation problem that uses WhatsApp as the channel.
Whichever route you take, do the arithmetic first: fix your monthly volume and mix, price Meta's share from the rate card, add the provider's layer, and only then decide whether a build on top is justified. If the number is small, buy a platform. If it is large, owning the integration pays for itself.
