AI Operator + human team

Interactive demo โ€” try it here, not through a scheduled meeting. The last question is deliberately outside the bot's knowledge: it writes an internal note and a human replies โ€” the customer simply experiences the business answering.

How it works

Switch WACO on in 3 steps.

Skip the weeks of onboarding. All you need is ten minutes and your business WhatsApp number.

๐Ÿ”—

Connect the number

One click, Meta's official popup, an OTP. A number already used in the WhatsApp Business app comes along without losing old chats.

ยฑ 3 MINUTES
๐Ÿ‘ฅ

Invite the team, reply together

Everyone answers from one inbox โ€” labels, private notes, automatic assignment. No per-seat fee.

DAY ONE
โš™๏ธ

Automate your messages

Form filling, reminders, broadcasts, payment confirmation, even an AI Operator if you need one. Every option lives in the same dashboard.

WHENEVER YOU ARE READY
Why WACO

We have already done the hard part of the WhatsApp API.

Registering for the WhatsApp Business API and pushing the paperwork through normally takes weeks. We have already shortened it โ€” and you never open a Meta dashboard at all.

โšก

Live in minutes

Click one button, follow Meta's popup, enter the OTP โ€” done. Business verification runs in the background without getting in your way.

๐Ÿ‘ฅ

Unlimited seats

Add your whole team with no per-person fee. Rationing staff access to save money only creates more work โ€” so we do not charge for it.

๐Ÿงพ

No markup on message fees

Message fees go straight to Meta at their official rates. We do not add a cent โ€” because we are genuinely not permitted to.

๐Ÿ“ฑ

Your existing number keeps working

Your existing WhatsApp Business number can be connected without losing its message history. Your phone keeps working alongside it.

๐Ÿฉบ

When something fails, you know why

WhatsApp sometimes refuses messages silently. The WACO dashboard translates the reason for you โ€” with a button that leads straight to the fix.

More than replying

A mini CRM in one dashboard.

WACO gives you richer message automation without another app. Scheduling reservations and sending reminders simply gets easier.

๐Ÿ“

Forms inside WhatsApp

Customers fill in their name, date, and branch right inside WhatsApp. Their answers become scheduled reservations on your team's calendar automatically.

โฐ

Automated reminders

Day-before confirmations, same-day reminders, even birthday greetings โ€” all sent automatically. You set them up once.

๐Ÿ’ณ

Manual-transfer payment confirmation

Customers send proof of transfer in the chat. The details are recorded neatly in the conversation and can feed straight into your billing system.

๐Ÿ›’

Catalog & orders in the chat

Customers pick products and quantities from a catalog in the chat, then receive the order details and how to pay. All recorded automatically.

๐ŸŽฏ

Ad targeting from customer data

Customer addresses become location data for Meta & Google Ads targeting. You can also look for new prospects who resemble the customers you already have.

๐Ÿ“

Many branches, one agenda

Every branch keeps its own schedule and calendar. Each chat is tagged with its branch automatically, so nothing gets mixed up. More on multi-branch โ†“

๐Ÿ“ฃ

Broadcasts with a detailed report

Message many contacts at once, greeting each person by name automatically. The report is plain: who read it, who replied, and what failed to send.

๐Ÿ”’

Your own chat workspace

Your data is stored separately, never mixed in with other customers'. Ready to use in minutes.

Running several branches?

Manage every branch's admin number from one WACO dashboard.

Different branch, different admin number? Not a problem โ€” every admin number you have can be run from the same dashboard.

๐Ÿค’

The admin is on leave and nobody replies

Branch chats pile up on one phone. The moment that person is away, customers of that branch are left waiting.

๐Ÿ™ˆ

Owners cannot tell which admin is active

There is no way to see who replied, how quickly, or what was promised to the customer.

๐Ÿšช

Staff resign and the contact list leaves too

If the number is in a staff member's own name, they walk away with it โ€” and with the entire customer history.

How does it work?

All three problems share one root: branch chats are scattered across personal phones. Connect each branch number to your WACO dashboard โ€” the chat history stays, every branch stays visible, and the numbers stay with your business.

Each branch = one inbox

Every admin number you register gets its own inbox, kept neatly apart from the other branches.

Managers see every message

Owners and managers run all of the branch inboxes from the same dashboard. Nothing slips past.

Reminders from one place

Send reservation reminders to each branch's contacts from a single dashboard, without risking a block from Meta.

You pay per number, not per person. US$20/month already includes one number and unlimited seats. Each additional branch number is +US$10/month.

Team inbox

More than WhatsApp โ€” a complete CRM for your team.

One workspace for the whole team: share the inbox, split the work, leave notes for each other. All of it included, with no extra fee and no extra app.

๐Ÿ’ฌ

Shared inbox

Everyone replies from one place. Chats stop piling up, and every conversation is stored in full.

๐Ÿท๏ธ

Labels & contact attributes

Tag your contacts โ€” "returning customer", "overdue", "priority" โ€” then message them by the categories you created.

๐Ÿ“

Internal notes

Leave a message for a colleague inside the conversation, say "already promised a 10% discount", invisible to the customer. Coordinating across the team gets easier.

๐Ÿ‘ฅ

Teams & auto-assignment

Incoming messages are spread across whoever is available, or routed to a specific team. Nothing is missed and nothing piles up on one person.

โฐ

New-customer notifications

If a first message from someone new goes unanswered for 10 minutes, the owner or manager is notified that a message is still waiting โ€” before that prospect walks next door.

๐Ÿ“ฌ

Weekly report

A summary lands in your email every Monday: how many chats, how many new customers, how many came from ads โ€” without opening the dashboard at all.

Plus: quick replies & macros, customer satisfaction ratings (CSAT), business hours, greetings & out-of-hours auto-replies (you choose which channels use them), stored conversation history, and a live chat widget for your website โ€” on as many sites as you own, all at no extra cost.

More than WhatsApp

Messages from every channel in one inbox.

Run more than one website or channel? Connect them to WACO, and every message that arrives โ€” from any channel โ€” can be handled in one dashboard by your whole team.

Instagram DM is one click, website live chat and Telegram are a switch away, and all of it lands in the same inbox. Install the live chat widget on as many sites as you own, at no extra cost.

๐Ÿ”Œ

๐Ÿงพ

Send reply-button or list messages from your system; the choice comes back through your webhook. A ready recipe: offer packages, send a payment QR, confirm payment โ€” exactly how WACO bills its own subscriptions over WhatsApp.

๐Ÿ”

WhatsApp OTP

Send verification codes over WhatsApp for logins and transactions in your app. Ready to use, with no template plumbing to build.

๐ŸŽฏ

Ad conversions tracked

Chats from Meta & Google ads are tracked automatically, and buyers are reported back to the ad platform. Can be triggered from your POS or order system the moment a payment lands.

๐Ÿ”—

n8n, Make & Zapier

Your favourite automation flow connects to WACO as an ordinary webhook, no custom node needed. A ready-made n8n workflow ships with signature verification built in.

๐Ÿ“Š

Airtable โ†’ Reservations

Schedules your team keeps in Airtable are pulled into WACO as reservations automatically. Safe to run again and again, with no duplicate records.

๐Ÿข

Scale & enterprise needs

Need more than the standard? A dedicated workspace per customer, a warm standby in Singapore, and ISO 27001 & 9001 certification through IDCloudHost. Written SLAs and annual contracts are available.

Cost

Work it out yourself. Nothing is hidden.

Only two things are ever billed, and you can see both: your WACO subscription, and the message fees paid directly to Meta โ€” not through us.

Meta charges per message and prices it by the country your recipients are in. The Singapore figures below are Meta's own, taken from Meta's rate card โ†— with USD selected (effective 1 July 2026). Sending elsewhere? Pick your market there โ€” it displays in US dollars too โ€” and type the rates in.

Utility / notifications (US$) Marketing (US$)

Everything in US dollars, the same currency as your US$20 subscription โ€” no conversion to work out. Authentication messages are priced the same as utility.

Conversations started by your customer need no template.* The template rates above only apply to messages you send first โ€” appointment reminders, invoice notifications, order updates.

WACO subscriptionUS$20.00
Incoming conversations (no template fee)US$0.00*
Outgoing notifications โ†’ paid to MetaUS$0.00
Promotional broadcasts โ†’ paid to MetaUS$0.00
Estimated total per monthUS$0.00

*The US$20 subscription is ours and fixed. Message fees are Meta's, billed by Meta directly to you, and priced per message by the country your recipients are in โ€” so the figures above are only as accurate as the rates you enter. Utility templates delivered inside an open customer service window are free, and chats started from a Click-to-WhatsApp ad are free for 72 hours. Current rates and volume tiers, effective 1 July 2026: Meta's official rate card โ†— ยท developer pricing documentation โ†—. We take no margin on any of it โ€” that is why we send you to Meta's own page rather than quoting a number we cannot keep accurate.

Who uses it

Built for teams whose customers live on WhatsApp.

"Patients ask about schedules over WhatsApp, but one person holds the phone. When they are off, nobody can answer."

Clinics & practices โ€” schedules, appointment confirmations, day-before reminders, and patient history that does not vanish when staff change.

"We want to tell parents when their child is absent โ€” without copying numbers one by one every morning."

Schools โ€” attendance notifications and announcements over the API, straight from the system you already run. Parents' replies land in the team inbox.

"The questions are always the same: internet is down, when is the due date. But every customer still has to be answered individually."

ISPs & subscription services โ€” auto-replies for repeated questions, invoice reminders over the API, and a support team looking at one queue.

FAQ

The questions we hear most.

Fuller answers โ€” including how to fix a rejected template and prepare for business verification โ€” are in the WACO guides.

Can I use WACO from outside Indonesia?

Yes. WACO is operated from Indonesia by PT Cloud Hosting Indonesia, but the WhatsApp Business API itself is global and nothing stops a business abroad from using the platform. Support is available in English and Indonesian, 24 hours a day, through the chat bubble on this page.

I have a website โ€” can I add live chat?

Yes, and it is included in the subscription โ€” on as many websites as you have: your main site, campaign landing pages, other brands, all free and each with its own snippet. Enable the website channel in the dashboard, paste one snippet, done โ€” visitor chats land in the same inbox as WhatsApp, answered by the same team, with no separate app. The chat bubble in the corner of this page is the example: it is WACO's own website channel.

My business is small โ€” is the free WhatsApp Business app not enough?

It may well be enough, and if so do not pay us yet. One person answering, fewer than about 30 chats a day, one location โ€” Meta's free app is still the right tool. The moment to move is usually when two or three of these appear: several people answering in turns (messages start getting missed or answered twice), broadcasts hitting the 256-contact limit, staff leaving and taking the chat history with them, or opening a second branch. We wrote this out honestly in "when you actually need WACO" โ€” and moving later costs you nothing: your old chats and contacts come along.

My number is already used in the WhatsApp Business app. Will I lose my chats?

No. A number already active in the WhatsApp Business app can be connected without losing chats or contacts, and the phone keeps working alongside the team inbox. This is an official Meta feature, not a workaround.

Who bills the message fees?

Meta, directly to you, at their published rates. WACO only bills the US$20 subscription. We add no markup on message fees โ€” and as an official Tech Provider we are not permitted to. Your estimated Meta bill is always visible in your dashboard. You add a payment method once on Meta's billing page โ€” our getting-started guide walks you through it, and answering customer chats keeps working while you sort it out.

Is this the official WhatsApp API?

Yes. WACO connects through Meta Cloud API as a verified Tech Provider. No WhatsApp is connected through a jailbroken phone or a hidden browser session โ€” those methods can get your number permanently banned, and we do not touch them.

Do you help me get connected? How far does that go?

Yes โ€” we walk you through the whole setup remotely (at no extra charge), as long as two things are in place: your business WhatsApp number and a Meta business portfolio that has passed verification. From there โ€” connecting the number, preparing your team inbox, your first template โ€” we work on it with you until it runs.

The honest limit: if the Meta portfolio itself has problems โ€” verification rejected, account restricted, business documents not accepted โ€” that sits between you and Meta; no provider can bypass it. We will point you in the right direction (see the verification guide), but the final call is Meta's.

What happens if I stop subscribing?

Your WhatsApp number, your Meta account and all conversation data remain yours. Access to the team inbox stops, but we delete nothing as a collection tactic, and there is no annual contract binding you.

Why do I need a template to message someone first?

It is a WhatsApp rule: free-form messages are only allowed within 24 hours of the customer's last message to you. Outside that window, messages must use a Meta-approved template โ€” an appointment reminder, for example. You can create and submit templates straight from the WACO dashboard without opening Meta Business Manager.

How long until we can use it?

Connecting a number takes about three minutes. Meta's business verification (to pass the initial 250-contact daily limit) runs separately and usually takes a few days โ€” and you can use the system while you wait.

Is my conversation data mixed with other customers?

No โ€” and this is genuine infrastructure-level isolation, not merely a logical separation: every paying customer gets their own inbox instance, with its own application and its own database, provisioned automatically once payment is received (usually 10โ€“15 minutes). Your patient or customer data never shares a database with another business, and that is written down in our privacy policy. The operator, PT Cloud Hosting Indonesia (IDCloudHost), is certified to ISO/IEC 27001:2022 (information security management, certificate IS 792648) and ISO 9001:2015 (FS 773988) by BSI โ€” verify it directly in the BSI directory โ†—.

Can I use it to send OTP codes for my application?

Yes, and the flow is ready-made: enable it once in the dashboard, then your application calls two endpoints โ€” send a code and verify a code. Code generation, expiry, attempt limits and storage are handled by us. You pay the normal WhatsApp message fee, directly to Meta with no markup.
