Predictable billing, however many chats your team sends
All three tools connect your number through Meta's WhatsApp Business API, which is why each pricing page lists message charges on top of the plan:
- Wati: marketing, utility and authentication messages are charged per message on its rate card.
- SleekFlow: S$19 a month to host the number, plus per-message fees on its own rate card.
- respond.io: incoming messages are free, and outgoing ones start at US$0.0002 each and vary by country and type.
We connect your number for you instead, with no Meta fee per message. Automated messages are paced within daily limits and sending hours, to keep your number in good standing. What you pay each month is the plan price, plus S$15 for each extra person or S$29 for each extra number.
Simple set up: we connect your number for you
On the tools, the setup is your job. Wati's dedicated onboarding is free on annual plans and a one-time fee on monthly ones. SleekFlow Pro gives you group sessions, and its 60-day onboarding costs S$1,299. respond.io's 28-day onboarding program is an add-on.
You keep replying to customers while our team connects the number and sets up your job board, with no setup fee. The WhatsApp Business app keeps working on your phone.
On Wati, the CRM is an integration. On ours, it's in the price.
Wati Growth connects to two CRMs by integration. SleekFlow and respond.io track each contact through lifecycle stages, and SleekFlow also gives you a kanban board on every plan, which is close to what we do.
Our WhatsApp Inbox comes with the CRM for all three of you. Because every chat is filed against the lead, whoever picks it up reads the whole thread before they reply. Jobs move along a board from Enquiry to Quote sent, Job booked, Job done and Paid. Put a reminder on a quote and it comes back to you on the day, and for quotes that need a nudge, an email sequence sends the follow-ups for you.
AI replies: included, an add-on, or the plan above
- SleekFlow Pro includes AI agents.
- Wati lists its Astra AI agents as an add-on from Pro, which is S$329 a month billed annually, and Astra Pro is $99 a month on Wati's Astra pricing page.
- respond.io Starter has no AI agents; they start on Growth, at US$159 a month billed yearly (about S$203).
- Ours is the Inbox + AI Agent plan at S$239 a month on an annual plan, for up to 500 AI conversations a month. You train the agent on your own answers, and when a customer needs a person, it hands the chat to your team with the full thread.
Pick a tool instead if one of these sounds like you
- You send broadcast campaigns to your whole list. All three tools do that, while our inbox sends normal chats, one conversation at a time.
- Your customers also message you on Instagram, Messenger or TikTok, and you'd like those chats in the same inbox. Ours is for WhatsApp.
- Someone on your team likes building chat flows and has time to keep them current.
- You want every conversation exported when you leave: respond.io exports contacts, conversations and message history on every plan, where ours exports your customer list as a CSV.
- Only one person answers your WhatsApp, in which case the free WhatsApp Business app is enough for now.
How to leave each one, and what you take with you
- Ours: monthly plans have a one-month minimum, then 30 days' notice. Annual plans are paid up front, with no refund after 14 days. You can export your customer list as a CSV any time.
- Wati: cancel any time. Wati doesn't refund payments already made.
- SleekFlow: its pricing page states no minimum term. It lists chat export on Enterprise only.
- respond.io: cancel any time and your plan runs to the end of the billing cycle, with export on every plan.
