SleekFlow costs a Singapore business S$209 a month for Pro or S$419 a month for Premium when billed yearly (S$2,508 and S$5,028 paid up front), or S$259 and S$519 on monthly billing, with Enterprise quoted on request. On top of the plan you pay S$19 a month to host each WhatsApp API number, plus WhatsApp message charges from a prepaid US dollar wallet at SleekFlow's rate card.
These are the prices as listed on SleekFlow's pricing page in November 2026, check their site for changes. Below we break down each plan, list the costs that sit outside the headline price, run a worked monthly bill for a three-agent Singapore team, and set it against RichAutomate's monthly plans.
SleekFlow plans in Singapore, plan by plan
SleekFlow's Singapore page shows prices in SGD and offers a yearly toggle ("save up to 20%") and a monthly toggle. It lists three tiers: Pro, Premium and Enterprise. The Essential plan that appears on the global SleekFlow pricing page (US$49 a month billed yearly, US$69 billed monthly, 3 seats) is not shown on the Singapore page, so ask SleekFlow whether it is sold to Singapore accounts.
Pro: S$209 a month yearly, S$259 monthly
Pro includes 3 user seats, 500 monthly active contacts and 3 channels. You get AI agents, broadcast campaigns, the Flow Builder automation tool, integrations with Shopify, Google Sheets, Zapier, Make and Facebook Lead Ads, basic analytics, API access, 3,000 AI credits a month and group onboarding sessions. Billed yearly, that is S$2,508 paid once.
Premium: S$419 a month yearly, S$519 monthly
Premium raises the limits to 5 user seats, 1,000 monthly active contacts and 10 channels, and adds AI agents that call your own APIs, role-based access control, HTTP request and webhook automations, HubSpot and Zoho integrations, Meta Conversions API, advanced analytics, multiple workspaces and 15,000 AI credits a month. A 60-day dedicated onboarding programme is included. Billed yearly, that is S$5,028.
Enterprise: custom
Seats, contacts and channels are set by contract, with a dedicated customer success manager. No price is listed publicly.
The costs outside the plan price
The plan fee is only part of a SleekFlow bill. These items come from SleekFlow's own pricing page and help centre:
- WhatsApp number hosting: S$19 a month per WhatsApp Business API number.
- WhatsApp message charges: billed "per SleekFlow rate card". The help centre lists Singapore per-message rates in US dollars, effective 1 October 2026: marketing US$0.08418, utility US$0.01840, authentication US$0.01840 and service US$0.0160. The article says WhatsApp fees are charged by Meta. Whether the card includes any SleekFlow margin is not listed publicly.
- Top-ups: message credit is prepaid in US dollars through Stripe. SleekFlow's docs set a minimum top-up of US$20 and a maximum of US$2,000 per transaction, and auto top-up is available.
- Extra seats: the Singapore page says a seat add-on is available but does not list an SGD price. The global page lists US$25 per extra seat on Pro and Premium.
- Extra contacts: also "available" on the Singapore page with no SGD price; the global page lists US$20 per 100 monthly active contacts. Helpfully, SleekFlow's help centre says a broadcast recipient who never replies does not count as an active contact.
- AI credits: US$20 per 5,000 extra credits.
- Optional add-ons: CX Intelligence analytics from S$129, and 60-day dedicated onboarding at S$1,299 one-off on plans where it is not included.
One point in SleekFlow's favour: its Singapore page describes a pre-approved package under Enterprise Singapore's EDGE Grant, which it says can cover up to 50% of the qualifying package cost for SMEs. WhatsApp messaging fees are excluded. If you qualify, that changes the subscription maths, so check eligibility before comparing.
SleekFlow vs RichAutomate: plans side by side
RichAutomate bills in US dollars; the SGD figures below use about S$1.28 per US dollar as of 29 October 2026, the same basis as our WhatsApp API pricing in Singapore page. Every RichAutomate plan fee is credited in full to your wallet, so it is spent on your usage rather than added on top. Our own fees are S$0.0026 per message plus S$0.0051 per 24-hour conversation window opened.
| Plan | Monthly price | Seats / users | Meta message charges | Markup on Meta rates | Setup fee |
|---|---|---|---|---|---|
| SleekFlow Pro | S$209 billed yearly, S$259 billed monthly | 3 included; add-on price not listed in SGD | Prepaid USD wallet at SleekFlow rate card (SG marketing US$0.08418) | Not listed publicly | None listed; dedicated onboarding S$1,299 optional |
| SleekFlow Premium | S$419 billed yearly, S$519 billed monthly | 5 included | Prepaid USD wallet at SleekFlow rate card | Not listed publicly | None listed; 60-day onboarding included |
| SleekFlow Enterprise | Custom | Custom | SleekFlow rate card | Not listed publicly | Custom |
| RichAutomate Starter | S$12 (US$9), credited to wallet | 2 team members | Meta bills your own card directly, at Meta's rate | None | None |
| RichAutomate Pro | S$19 (US$15), credited to wallet | Up to 5 team members | Meta bills your own card directly, at Meta's rate | None | None |
| RichAutomate White-label | S$24 (US$19), credited to wallet | As Pro, plus up to 10 client accounts | Meta bills your own card directly, at Meta's rate | None | None |
Outside India, RichAutomate offers only Client Pay. Meta invoices your business at its own rate on the card in your Meta Business Manager, and we never touch that charge. For Singapore recipients in October 2026, Meta's rates are about S$0.0937 for marketing, S$0.0205 for utility and S$0.0205 for authentication. Service replies are free for the first 1,000 per number per month inside the 24-hour customer service window, then about S$0.0205. All rates exclude GST.

Worked example: 3 agents and 2,000 marketing messages a month
Take a typical Singapore SMB: three people sharing one inbox, one WhatsApp number, and 2,000 marketing template messages a month to Singapore customers. Assume customer replies are handled inside the 24-hour window and stay within the free service allowance, US dollars convert at S$1.28, and GST is left out on both sides.
| Cost line | SleekFlow Pro, monthly billing | SleekFlow Pro, yearly billing | RichAutomate Pro |
|---|---|---|---|
| Plan fee | S$259.00 | S$209.00 | S$19.00, credited to wallet |
| WhatsApp number | S$19.00 | S$19.00 | Included |
| 2,000 marketing messages | S$215.50 (US$168.36 at US$0.08418) | S$215.50 | S$187.40 to Meta, on your card |
| Platform usage fees | Not listed separately | Not listed separately | S$15.40 at most, paid from the S$19 credit |
| Monthly total | S$493.50 | S$443.50 (S$2,508 plan paid up front) | S$206.40 |
The RichAutomate usage line works like this: 2,000 messages at S$0.0026 is S$5.20, and if every message opened a fresh window, 2,000 windows at S$0.0051 adds S$10.20. That S$15.40 is drawn from the S$19 plan credit, so the RichAutomate side of the bill stays at S$19 and the remaining S$3.60 carries forward in your wallet.
Two things drive the gap. The plan fee is the big one: S$259 against S$19. The second is the message rate itself: SleekFlow's card lists US$0.08418 per Singapore marketing message, about S$0.1078, against roughly S$0.0937 billed by Meta directly. That difference may come from currency conversion, timing of rate updates or a margin; SleekFlow does not say, so ask them which Meta rate their card is based on. Contact limits do not bite here: if fewer than 500 people reply to the campaign, Pro's 500 active contacts cover it.

Where SleekFlow earns its price
The cheaper bill is not the right answer for every team. SleekFlow is the stronger pick if:
- You sell across many channels. SleekFlow brings WhatsApp, Instagram, Facebook Messenger, WeChat, LINE, SMS, email and calls into one inbox. RichAutomate is WhatsApp-first and does not cover Instagram, Messenger, LINE or WeChat.
- You want AI agents wired into your CRM. Premium's API-connected AI agents and HubSpot and Zoho integrations are mature features.
- You want local, hands-on help. SleekFlow has a team on the ground in Singapore, group onboarding on Pro and a dedicated 60-day programme on Premium.
- You qualify for the EDGE Grant. A subsidised yearly package can narrow the gap considerably.
If most of your customer conversations happen on WhatsApp, the omnichannel premium buys features you will not use. We set out the switch in more detail on our SleekFlow alternative for Singapore page, and if you are also weighing respond.io, read SleekFlow vs respond.io in Singapore.
Compliance costs the same on either platform
Whichever tool you pick, Singapore's rules travel with your marketing messages. Under the PDPA Do Not Call provisions you need clear consent, or a check against the DNC Registry, before sending marketing to a Singapore number, and a DNC check is valid for 21 days. The Spam Control Act requires you to honour unsubscribe requests within 10 business days. Build an opt-out button into every marketing template and both platforms will handle the rest.
Which should a Singapore SMB pick?
If you need one inbox across Instagram, Messenger, WeChat and WhatsApp, or you want a subsidised yearly package with local onboarding, SleekFlow Pro or Premium is a fair buy, and the prices above are what you should budget. If WhatsApp carries most of your sales and support, RichAutomate Pro at S$19 a month, credited to your wallet, with Meta billing your own card at its own rate, is the leaner way to run the same campaigns.
