WhatsApp AI agents that reply, qualify and take orders for you

We build WhatsApp AI agents for businesses that get more messages than their team can answer. The agent replies the moment a customer writes or fills in a form, qualifies leads, answers from your real menu or catalog, takes orders and bookings, sends reminders, and hands the chat to a person when it should. Full automation starts from $1,499.

Full WhatsApp automation from $1,499. Final price depends on scope.

Who this is for

  • Businesses whose customers already message them on WhatsApp
  • Teams that lose leads because nobody replies quickly after a form is filled in
  • Restaurants, cafés, shops and service businesses answering the same menu, catalog and FAQ questions all day
  • Clinics, salons and other booking businesses that want reminders and follow-ups to go out on their own

What the agent handles

Reach and qualify new leads instantly

When someone fills in a form on your site or an ad, the agent messages them on WhatsApp straight away, asks your qualifying questions and sends qualified leads to your team or CRM with the answers attached.

Answer menu, catalog and FAQ questions

The agent answers from your real menu, catalog, price list and FAQs, and can send menu or product images. It checks prices against your data before quoting them, and says so when it does not know.

Take orders and bookings

It collects items, quantities, address and payment method, or finds a free slot, then shows the customer a summary to confirm. After the customer confirms, it records the order or booking and notifies your team.

Send reminders and follow-ups

Booking reminders, follow-ups on unanswered quotes and post-visit messages go out on schedule, using approved WhatsApp templates where the rules require them.

Hand off to a human

When a customer asks for a person, complains, or needs something outside the agent's scope, the chat moves to your team. Staff get an alert on WhatsApp with the customer's message, and the agent stays quiet until it is asked back.

Why reply speed matters

A lead who waits goes cold. In a Harvard Business Review study of 1.25 million online leads, firms that tried to contact a lead within an hour were "nearly seven times as likely to qualify the lead" as firms that waited even an hour longer (HBR, March 2011). A WhatsApp agent answers straight away, at 2 a.m. and on public holidays.

How we connect to WhatsApp

We build on both Meta's official WhatsApp Cloud API and unofficial gateways such as Evolution API, and recommend one per project after explaining the trade-offs. The official API is the right choice when the agent messages people first, like lead reach-back and reminders, or when volume will grow. A gateway such as Evolution API can suit reply-only agents on an existing number where staff keep using the phone app, with account risk you should understand first.

What changes for your business

Replies at any hour

The agent answers menu, catalog and FAQ questions the moment they arrive, at night and on public holidays, in the customer's language and by voice note when they speak.

Your team handles only what needs a person

Routine questions, order taking and booking back and forth go through the agent. Staff get a WhatsApp alert when a chat needs them, with the customer's message attached.

No extra hire just to answer messages

The agent absorbs the volume, so growing enquiries do not mean adding staff to reply on WhatsApp.

What you get

  • A WhatsApp AI agent on your business number, on Meta's official WhatsApp Cloud API or an unofficial gateway such as Evolution API, whichever we recommend for your project
  • Conversation flows for the use cases you pick: lead qualification, questions, orders or bookings, reminders and handoff
  • A knowledge base the agent answers from, which your team can update
  • Connections to your forms, CRM, Google Sheets, calendar or order system
  • Human handoff with staff alerts and an automatic return to the agent
  • Voice note support where your customers use it
  • Monitoring during launch, a handover session and documentation

How we work

  1. Scoping: we go through the chats you get today and what a good answer looks like, and you get a quote
  2. Flow design: we agree the flows, the handoff rules, the connection and the systems to connect
  3. Build and test: we build in n8n and test on a separate number with real questions from your chats
  4. Go live: we switch on your number and watch the first conversations closely
  5. Tune and hand over: we adjust answers from real chats, then hand over the documentation

Frequently asked questions

How much does a WhatsApp AI agent cost?

Full WhatsApp automation starts from $1,499. The final price depends on how many conversation flows you need, which systems the agent connects to, whether it handles voice notes, and how much it needs to know about your business. We quote after a short scoping conversation.

Do you use the official WhatsApp API?

Yes. We build on Meta's official WhatsApp Cloud API and on unofficial gateways such as Evolution API, and recommend one for each project. The official API suits agents that message customers first and numbers with growing volume. A gateway can suit a reply-only agent on an existing number, and we explain its account risk before you decide.

What happens when the agent cannot answer?

It hands the chat to a person on your team, alerts them on WhatsApp with the customer's message, and stays quiet until the customer asks for the assistant again. You set the rules: complaints, refunds, wrong orders, or anything the customer asks a human for.

Can the agent take orders and bookings?

Yes. It collects the details, shows the customer a summary to confirm, then records the order or booking and notifies your team. Our restaurant agents take delivery orders this way, including the address, phone number and payment method.

Can it follow up with leads from my website forms?

Yes. When someone fills in your form, the agent messages them on WhatsApp straight away, asks your qualifying questions and passes qualified leads to your team or CRM. On the official API this first message uses an approved template, which we set up with you.

Does it understand voice notes and other languages?

Yes. Our agents transcribe voice notes, answer in the customer's language and can reply with a voice note. Our live builds handle English, Roman Urdu and Urdu voice notes.

Who owns the agent once it is built?

You do. The workflows run in n8n on infrastructure you control or that we run for you, with documentation and a handover session. Your data stays in your own database.
