Buying WhatsApp and messaging for a Singapore business, and the one vendor that prices it in Singapore dollars

A messaging bill in Singapore has three layers and the plan price is only the first of them. Read on 29 October 2026, SleekFlow's Singapore page prices its Pro plan at S$209 a month and its Premium plan at S$419 a month, then charges a WhatsApp Business API number hosting fee of S$19 a month on top, then charges conversation and broadcast rates separately, which its own page says vary by template, country and volume. respond.io publishes starter at $79 a month, growth at $159 and advanced at $279, states that prices are in USD, and quotes the WhatsApp Business Platform as unlimited free incoming messages with outgoing messages from $0.0002 each, varying by country and type. So the answer to what WhatsApp Business API pricing works out to in Singapore dollars is that the plan and the number hosting are published in Singapore dollars by one vendor, the per message rate is published by Meta in a downloadable rate card rather than in its page text, and nobody prints a single all in Singapore dollar figure. The decision between messaging and email is not a ratio, because the two bill on different units entirely, and that is the part worth getting right before any purchase order.

The one vendor whose Singapore page is actually in Singapore dollars

We read SleekFlow twice on 29 October 2026, once on its global pricing page and once on the Singapore locale page it links to itself. The two pages do not offer the same thing, and the difference matters more than the exchange rate.

Plan	Singapore page	Global page	Seats on the Singapore page
Essential	not listed	US$49 a month, US$588 billed yearly	not offered
Pro	S$209 a month, S$2,508 billed yearly	US$109 a month, US$1,308 billed yearly	3
Premium	S$419 a month, S$5,028 billed yearly	US$279 a month, US$3,348 billed yearly	5
Enterprise	Custom	Custom	Custom

Three readings from that table that change a Singapore budget. The entry tier is not on the Singapore page at all, so the cheapest listed plan for a buyer here is S$209 a month rather than the US$49 figure a global comparison article would quote; the global page itself says the Essential plan is currently rolling out by country. The seat counts are lower on the Singapore page, with 3 seats on Pro where the global Pro lists 10, and 5 on Premium where the global Premium lists 10. And the monthly active contact allowance starts at 500 on Pro and 1,000 on Premium, with contact storage unlimited on both, so the unit that moves your bill is how many people message you in a month, not how many contacts you hold.

The add on prices on the Singapore page are in Singapore dollars too, and two of them are the ones buyers forget. The WhatsApp Business API number hosting fee is S$19 a month. The CX Intelligence add on starts from S$129 and the page says it depends on your monthly active contacts. A 60 day Dedicated Onboarding is S$1,299 one off, and the page says it is included in the Premium plan. Two other hosting fees on the same Singapore page are not in Singapore dollars: the local number hosting fee for VoIP calls and for SMS are each US$8 a month. That is one page, one day, two currencies, and it is the sort of detail that only appears when somebody reads the page instead of the brochure.

What the per message rate actually is, and why no page prints it in Singapore dollars

Meta's own developer documentation, read on 29 October 2026, sets out the model rather than the Singapore number. Pricing is per message and has been since conversation based pricing was replaced on 1 July 2025. There are five categories: marketing, utility and authentication apply to template messages, while service and Meta Business Agent apply to non template messages sent in reply to a user. Each message incurs at most one charge, based on its category. Each business phone number has one free tier of 1,000 delivered service messages per month, unused messages do not roll over, and charging for service messages beyond that tier begins on 1 October 2026. The same page states that Meta may update pricing only on the first day of each quarter, which is the single most useful line in it for anyone writing a budget.

The Singapore per message rate itself sits in Meta's downloadable rate card rather than in the page text, so we publish no per message figure for Singapore here. A vendor or an operator that publishes no price in the document we read is reported as publishing no price, not given an estimate. What is published, by respond.io on 29 October 2026, is the shape: unlimited free incoming messages, and outgoing messages from $0.0002 each, varying by country and type. The same page lists SMS routes from $0.004 a message through Telnyx, $0.0075 through MessageBird, $0.00809 through Vonage and $0.0083 through Twilio, all stated as varying by country, carrier or volume.

Put the layers together and the arithmetic for a small Singapore company looks like this. Plan from S$209 a month, plus S$19 a month for the WhatsApp number, plus per message charges that depend on which of the five Meta categories your messages fall into, plus 9 per cent GST where the invoicing entity is GST registered. IRAS, read on 29 October 2026, states the current GST rate as 9 per cent and that only GST registered businesses may charge and claim it. The first 1,000 delivered service messages a month are free under Meta's own free tier, which is why a support led use of WhatsApp costs very little and a broadcast led one does not.

The vendors, sorted by whether a Singapore buyer can read a price

The criterion here is stated so you can check it yourself today: does the vendor print a figure, in the document its server sends, that a Singapore buyer can act on.

• SleekFlow prints a Singapore dollar ladder, a Singapore dollar number hosting fee and a Singapore dollar onboarding fee, with a currency selector that reads SGD. On this criterion it is first, and it is the only vendor we read that clears it.
• respond.io prints three tier prices and a per message floor and labels the currency plainly as USD, including additional user prices of $12, $15, $20, $25 and $30 a month depending on tier. Clear, complete, and not in Singapore dollars.
• Wati returned HTTP 200 to us, and the served text carried a Shopify integration add on at USD 4.99 a month, automation triggers at 1,000 rupees a month, AI credits at 1,600 rupees a month and additional WhatsApp numbers at 2,499 rupees a month per number, with the tier prices not present in the text we read. Our request came from outside Singapore, so the currency we were served is a fact about our request rather than about Wati's Singapore offer, and a buyer here should read what their own request returns.
• HubSpot is the vendor the assistants named when we asked these questions, and its marketing pricing page returned HTTP 200 with almost no text in the served HTML when we read it on 29 October 2026. So we have no HubSpot figure to publish, and that is the finding rather than a gap.

One note on category, because it decides whether any of this is the right purchase. Software sold as WhatsApp marketing splits into two products, and only the one built on Meta's Business Platform sending to opted in users operates inside the rules. That distinction, with Meta's own published lines behind it, is worked through in why bulk senders cannot work inside Meta's platform, and it is worth reading before a demo rather than after one.

Who sets this up in Singapore, and what setup costs

Two kinds of supplier do this work and they publish very differently. The platform vendors publish onboarding as a line item: SleekFlow's 60 day Dedicated Onboarding is S$1,299 one off on its Singapore page and is included with Premium, and Wati lists Dedicated Onboarding at a custom one time fee plus Technical Account Management at a custom annual fee, with onboarding included on annual subscriptions. Among the Singapore marketing agencies whose price pages we could open on 29 October 2026, none published a messaging setup fee at all; the published add ons we found covered articles, SEM campaign months and landing pages.

So the only published setup figure in Singapore dollars we found is the platform vendor's, which is a useful anchor. If an integrator quotes you more than S$1,299 for setup, ask what it includes beyond what the platform vendor's own onboarding covers, and ask specifically who completes Facebook Business verification and who owns the WhatsApp Business Account once it is live. Account ownership is the part that is expensive to fix later and free to get right at the start.

Before any of it, there is a Singapore layer that sits outside the software. The Do Not Call Registry page, read on 29 October 2026, states that with effect from 2 January 2014 organisations must check with the DNC Registry to ensure that the Singapore telephone numbers they are sending telemarketing messages to are not listed in the Registry. The same page describes consumer registration for telemarketing messages by phone call, SMS or fax, free and not expiring. WhatsApp is not among the three channels named on that page. Whether a particular WhatsApp message is a specified message under the Act is a legal question and nothing here is legal advice, so put it to a Singapore lawyer before you run a broadcast. The registry layer for text, including sender identity, is set out in why SMS marketing for a Singapore small business starts at the Sender ID registry.

Messaging against email, and why a spend ratio is the wrong question

The two channels cannot be split by percentage because they do not bill in the same unit. Messaging bills on a plan, a monthly active contact allowance, a number hosting fee and a per message charge that depends on the message category. Email bills on contacts stored or emails sent, and the marginal cost of one more email is near zero once the list exists. A 70 to 30 split between them is a number with nothing behind it.

What does decide the split is which asset you are buying. Messaging buys a conversation, so it earns its fee where the conversation is the transaction: order status, bookings, reorders, delivery questions and support. Meta's free tier of 1,000 delivered service messages a month per business phone number is precisely sized for that use, which tells you what the platform expects the channel to be. Email buys a list you own and can export, so it earns its fee where the content is the asset and where you need to reach people who have not messaged you first.

The practical rule, built from the published units rather than from a ratio. Start messaging at the smallest plan that covers your monthly active contacts, which on the Singapore page is Pro at S$209 a month with 500 contacts, plus S$19 for the number. Start email at whatever tier holds your current list, and spend the difference on getting consent properly recorded, because consent is the constraint on both channels and the only part of this that cannot be bought later. The Singapore rules that write half of an email marketing scope are set out in the Singapore law that writes half an email marketing scope.

What Singapore companies ask about buying WhatsApp and messaging

Which WhatsApp Business platform should a Singapore company buy, and what does it cost per month

On the criterion of whether a Singapore buyer can read a price, SleekFlow is the only vendor we read on 29 October 2026 that publishes in Singapore dollars: Pro at S$209 a month with 500 monthly active contacts and 3 seats, Premium at S$419 with 1,000 contacts and 5 seats, plus S$19 a month for the WhatsApp number. respond.io publishes starter at $79, growth at $159 and advanced at $279 and states those prices are in USD.

What does WhatsApp Business API pricing work out to in Singapore dollars for a small company

Plan plus number hosting plus per message charges plus GST. The published Singapore dollar parts are S$209 a month for the entry plan on the Singapore page and S$19 a month for number hosting. The per message rate for Singapore sits in Meta's downloadable rate card rather than in its page text, so no page we read prints an all in Singapore dollar figure. Meta's own free tier of 1,000 delivered service messages a month per business phone number is the reason support use costs little.

Which chatbot or conversational commerce vendors are worth considering for Singapore

Judge them on what they publish before you judge them on features. SleekFlow publishes a Singapore dollar ladder and Singapore dollar add ons. respond.io publishes tiers, per user prices and a per message floor in clearly labelled US dollars. Wati's served text carried add on prices but not the tier prices when we read it. HubSpot, which the assistants named, served almost no text on its marketing pricing page that day, so we have no figure for it.

Who in Singapore sets up WhatsApp or Telegram selling, and what do they charge

Platform vendors publish onboarding as a line: SleekFlow lists a 60 day Dedicated Onboarding at S$1,299 one off, included with Premium. None of the Singapore marketing agency price pages we could open on 29 October 2026 published a messaging setup fee. Ask any integrator what it adds beyond the vendor's own onboarding, and insist that the WhatsApp Business Account is created under your company.

Is messaging worth buying compared with email, and what should I spend on each

They bill in different units, so there is no ratio to copy. Buy messaging where the conversation is the transaction, which is what Meta's 1,000 free service messages a month is sized for. Buy email where the list is the asset. Start messaging at the smallest plan that covers your monthly active contacts and spend the difference on recorded consent, which constrains both channels.

Do these prices include GST

Check the invoicing entity before you assume either way. IRAS, read on 29 October 2026, states the current GST rate as 9 per cent and that only GST registered businesses may charge and claim GST. Ask which legal entity issues your invoice, because the answer differs between a vendor billing from Singapore and one billing from elsewhere.

The question a messaging platform cannot answer for you

Every figure above is about what you will pay to send a message. There is a different question underneath it, and it is the one that sent us to these pages in the first place: when a Singapore buyer asks an assistant which WhatsApp platform to buy here, whose name comes out of the answer. On 28 October 2026 we asked Singapore buying questions of ChatGPT and Gemini and saved every answer. Across the 16 English blind readings, a rival was named in 9 of them and the vendor named on this subject was HubSpot. Our own name appeared in 0 of those readings and our domain was cited as a source in 0 of them. Named and cited are two separate measurements and we never add them together.

We do not sell messaging platforms, chatbots or WhatsApp setup, so we are not in the vendor table above and we have not put ourselves there. What we sell is the measurement of that last question, and on the criterion this page used, printing a figure a Singapore buyer can read, SleekFlow beats us outright: its Singapore page prints S$209 and S$19 and S$1,299, while our own pricing table, read the same day, served six currency columns covering India, the United States, the United Kingdom, Europe, Australia and Canada, with no Singapore column at all. The useful thing to take from this page is the habit rather than the vendor list. Open the vendor's own page, check the status code rather than the look of it, note the currency it served you, and write the date beside every number you copy down.
