Stop making the calls by hand

Picture the scheduling calls your team dreads, gone by tomorrow.

An AI voice agent phones your customers, offers real times from your calendar, books or moves the appointment on the call, and writes it straight into your systems.

Today, arranging appointments by phone burns hours of your team's day. They call customers to book technician visits, confirm deliveries and chase reschedules, and the calls that don't connect pile up as voicemail and callbacks. Empty slots from no-shows quietly cost money, and customers sit in a queue waiting for someone to ring back. It is high-volume, pattern-based calling โ€” the kind that buries a healthcare front desk in recall and reminder calls โ€” that ties up good people without needing their judgement on a single call.

Avaib takes a different approach. We are a software company first, so we treat an outbound scheduling agent as the hard real-time engineering problem it really is: the split-second timing that keeps a call natural, the connection to your calendar and CRM so every booking is real, and a clean escalation to a person. It builds on the same foundations as our AI voice agents for inbound calls. One accountable team, code you own, at a cost-effective rate.

How it works

What happens on a single scheduling call.

From the moment the agent dials to a booked appointment logged in your system, here is the sequence it runs on every call.

01

The agent places the call

Working from your list, the agent dials each customer at a sensible time, introduces itself as an AI assistant for your business, and explains why it is calling, whether that is to book, confirm or reschedule.

02

It has a natural conversation

It listens, answers the caller's questions in plain speech, and offers real available slots from your live calendar, adjusting to a "not that day" or "only mornings work" the way a person would.

03

It books or reschedules on the call

Once the caller picks a time, the agent locks it in, moves an existing appointment if needed, and confirms the details back to them out loud so everyone is clear before it hangs up.

04

It updates your systems

The booking is written straight into your calendar, CRM or scheduling tool through their APIs, so your diary and records are correct the moment the call ends, with nothing to retype.

05

It escalates the exceptions

When a call needs a human, an unusual request, a complaint, a caller who asks for a person, it captures what it has and hands it to your staff with the context, instead of guessing.

Want to see this run on your kind of call? We'll map it to how you actually book.

Use cases

The calling that's costing your team hours.

Wherever a business regularly rings customers to arrange a time, an AI voice agent can take the calls. These are the ones we're asked for most.

A business professional making an outbound scheduling call at a desk โ€” Avaib

Field-service technician visits

Instead of staff manually calling hundreds of customers to book technician visits, the agent calls each one, offers the next available windows, books the slot and writes it into your scheduling system, all without tying up the office.

A staff member confirming a booking in a scheduling system โ€” Avaib

Appointment reminders & confirmations

Every appointment gets a confirmation and reminder call ahead of time, so the customers who need to move or cancel do it early. Picture a calendar that stays full instead of leaking empty slots, and a team that never works through another call list.

A logistics dispatcher coordinating delivery schedules โ€” Avaib

Delivery & installation scheduling

The agent rings customers to agree a delivery or installation window, offers the slots your routes allow, and updates the job the moment it is set, keeping drivers and fitters on a schedule that actually holds.

A clinic staff member booking a patient appointment โ€” Avaib

Healthcare bookings & recalls

Recall and follow-up calls, check-up reminders and reschedules handled automatically, booked straight into the practice calendar, so front-desk staff are freed from the phone and patients are not left on voicemail.

A service marketplace coordinating jobs between customers and providers โ€” Avaib

Service marketplace matching

When a job comes in, the agent calls both sides to lock in a time that suits, confirms it, and updates the platform, turning the slow back-and-forth of matching a customer to a provider into a single automated call.

A consultant scheduling a client meeting โ€” Avaib

Consultation & renewal scheduling

For consultants and professional-services firms, the agent books consultations, review meetings and renewal calls into the right person's calendar, so opportunities are scheduled promptly instead of waiting for someone to pick up the phone.

Got a call type that isn't here? If your team makes it often and it follows a pattern, an agent can probably take it.

What makes it work on a real call

An agent your customers won't mind picking up for.

An outbound scheduling call goes wrong in a few predictable ways. Here's exactly what we engineer to avoid each of them.

It offers real slots, not guesses

The agent reads your live calendar, so every time it offers is genuinely free and every booking it makes is real. No double-bookings, no "we'll call you back", no diary that drifts out of sync with what was agreed on the call.

It sounds like a person, not a recording

Natural, human-sounding speech and a real back-and-forth. It handles being interrupted, copes with accents and background noise, and adjusts to "only afternoons" the way a person would, instead of ploughing through a script.

It hands exceptions to your staff

The agent knows its limits. A complaint, an unusual request, or a caller who wants a human triggers a clean hand-off with everything it has already gathered, so the tricky calls still get a person and nobody is stuck with a bot.

It calls compliantly and honestly

It discloses that it is an AI assistant, respects call timing, consent and recording rules, and is built with the privacy and data handling your sector expects, which matters everywhere and is essential in health and finance.

Want an agent that books cleanly and hands the tricky calls to your team? That's the whole point of how we build them.

Integrations

It works inside the calendar and CRM you already run.

The agent isn't a separate diary to keep in sync. It reads and writes your real systems through their APIs, so bookings are correct the moment a call ends. We stay tool-agnostic and connect to what you use.

Business benefits

What automated scheduling actually gives you.

Less manual calling, lower cost, fewer no-shows and no scheduling delays, delivered by a team that also owns the engineering and hands you the code.

No more manual call lists

Hand off the repetitive outbound calling that eats hours every day: booking, confirming and chasing all run on their own, so your people give their attention to the customers in front of them instead of the phone.

Lower operational cost

One agent makes hundreds of calls in parallel for a fraction of the staff time it replaces, and absorbs a busy week without a single hire, temp or overtime shift.

Fewer no-shows, fuller days

Consistent confirmation and reminder calls prompt customers to move an appointment early instead of missing it, so empty slots get refilled and your schedule earns its keep.

No scheduling delays

Customers are called and booked while the intent is still fresh, not left in a callback queue, so appointments lock in sooner and jobs start sooner.

Every call, done the same way

The agent follows your process on every single call, capturing the same details and updating the same systems, so nothing slips through and your records stay clean and complete.

Fits the systems you already run

It works inside your calendar, CRM and scheduling tools through their APIs, so there is no new place for staff to check and no double entry, just your existing diary kept correct.

Enterprise quality, without the price tag

Senior voice-AI engineering from around USD 25 per hour. One Canadian client cut their build investment by roughly 75% against local quotes and still received a solution backed by a 30-day warranty.

You own it, no per-minute lock-in

You own the code and the design, and we keep the voice, speech and phone providers swappable, so you are never trapped in one platform's rising per-minute pricing.

How we work

A clear path from a manual call list to a working agent.

From mapping how you book today to a tuned, supported agent live on real calls, proven before it phones a real customer.

01

Map the calls

We look at how your scheduling calls really go: who you call, what you ask, where slots come from, and which calls a human must take. Then we pick the ones the agent can genuinely handle.

02

Design the conversation

We script the flows, the questions it asks, how it offers slots from your calendar, and exactly when and how it escalates to a person, grounded in your real availability and rules.

03

Build & connect

We build the agent, wire it into your phone system, calendar, CRM and scheduling tools, and engineer the timing, interruption handling and hand-off so it holds up on a live call.

04

Tune on real calls

We test against real-world audio and awkward requests, tune the understanding and slot logic, and add monitoring, so it is dependable before it calls a real customer.

05

Go live & improve

We roll it out on a supervised campaign, watch the early calls closely, and keep refining from real conversations. We stay on to support and improve it, never vanishing after launch.

Who we build for

Built for the businesses that live on the phone to book work.

If arranging appointments by phone is costing you hours, here's the kind of organisation Avaib fits, and the problem we usually solve for each.

Service marketplacesMatching a customer to a provider means calls to both sides. The agent handles that outreach, agrees a time that suits everyone and updates the platform, so bookings happen without your team on the phone.

Common questions

AI appointment scheduling, answered.

What is AI outbound calling and appointment scheduling?

AI outbound calling and appointment scheduling is software that automatically phones your customers to book, confirm or reschedule appointments. An AI voice agent places the call, holds a natural spoken conversation, offers real available times from your live calendar, makes or moves the booking, and updates your systems, all without a staff member on the phone. When a call needs a human, it hands it over cleanly.

It replaces the repetitive manual calling a team does to arrange visits, deliveries and appointments. Done well it is less about the AI and more about the engineering around it: the split-second timing that keeps a call natural, the connection to your calendar and CRM so bookings are real, and a clean escalation to a person. That discipline is exactly what Avaib brings, drawing on more than 600 projects delivered since 2004.

How is this different from an automated text or robocall reminder?

A text or robocall pushes a one-way message: it can remind, but it cannot have a conversation, answer a question or actually change a booking. An AI voice agent talks with the customer, understands "can we make it Thursday instead", offers real slots and completes the reschedule on the call.

Because it connects to your calendar and CRM, the change is real and logged the moment the call ends, rather than leaving the customer to call back and your team to sort it out later.

Will customers know they are talking to an AI, and is that a problem?

The agent is upfront that it is an AI assistant for your business, which is both honest and, for automated outbound calls, a legal requirement in many places. In practice customers care far more about getting their appointment sorted quickly than about who sorts it.

And the moment a customer wants a person, or the call needs one, the agent hands over cleanly with the context already gathered. Nobody is trapped with a bot.

Can it book straight into our calendar and update our CRM?

Yes, and that is the whole point. We connect the agent to your calendar, CRM and scheduling tools through their APIs, so on the call it checks real availability, makes or moves the booking, and writes it straight back into the systems you already run.

Your diary and records stay correct in real time, with no double entry and nothing for staff to retype after the call.

What happens when a call is complicated or the customer is unhappy?

It escalates to a person. We design the hand-off rules with you: which situations always go to a human, and the moments, a complaint, an unusual request, an explicit ask for a person, that trigger a transfer with everything the agent has gathered.

The goal is never to trap someone with a bot. The agent handles the routine scheduling it does well and gets out of the way for anything that needs a human touch.

How many calls can it make, and can it handle a busy week?

A voice agent makes many calls at once, so it scales with your list without hiring or overtime. A campaign of hundreds of confirmation or booking calls that would take a team all day is handled in a fraction of the time.

You keep control of when it calls and how it behaves, and it follows the same process on every call, so quality stays consistent whether it is making ten calls or a thousand.

How much does an AI scheduling agent cost?

It depends on scope. A single, well-defined campaign like appointment reminders is a small, fixed engagement, while an agent that handles several call types and connects to multiple systems is larger. Avaib's model is senior engineering at a cost-effective rate, typically around USD 25 per hour, which is why businesses in Australia, the US, Canada and the Middle East work with us instead of paying big-firm prices. One Canadian client cut their build investment by roughly 75% against local quotes and still received the same high-quality solution, backed by a 30-day warranty.

There is usually a small ongoing running cost for the phone, speech and AI services the calls use, which we keep transparent and swappable. Tell us which calls are eating your team's time and we'll propose a right-sized engagement with a clear scope and a ballpark price, plus a free, no-obligation written estimate.

Do you support the agent after it goes live?

Yes. A scheduling agent improves with real calls, because you learn what customers actually ask and where it stumbles, so we stay on to monitor, tune and adapt it rather than vanishing after launch.

You get one accountable team for the whole journey, from mapping the first calls through to ongoing support, with a 30-day post-launch warranty on the work we deliver.
