The Cost of a Missed Call

Every Missed Call Is a Job Your Competitor Gets

On the first 95-degree day your phone rings more in one afternoon than in the previous month. Every ring that goes unanswered goes to whoever picks up first.

Answered Mid-Install

Most calls come while you’re on a job. That’s exactly when CallSide answers.

Lower Cost Than Hiring

24/7 call coverage without the overhead of staffing a receptionist around the clock.

Lead Details Captured

Caller details, service need, and appointment request are organized and sent to your team.

Work out what missed calls cost your business Takes about 30 seconds. Your numbers, not ours.
How it works

How It Works

Start with your calls. Add website chat when you need it.

Fully managed, done for you. You stay on the tools, we handle the phones.
1We learn your business

Your services, pricing, service area, hours, and exactly what counts as an emergency. We build it around how you actually run jobs.

2We build and launch your agent

We craft, test and tune an agent that knows your jobs and sounds like your best dispatcher — you pick the name and the voice, and approve every answer. You don’t lift a finger.

3It answers around the clock

Day, night and weekends. Every call becomes an organized lead in your inbox — and a booked job on your calendar when your calendar is connected.

Choose how calls reach the AI
Keep your numberEasiest Missed, busy and after-hours calls forward to the AI.

Your existing number forwards to the AI only when you don’t pick up — after hours, when you’re on a job, or when the line is busy. Customers keep calling the number they already know, and you still answer whenever you can.

Add a separate number A dedicated number for your website, ads or truck.

You get a second number that only the AI answers — put it on your website, your ads or your truck. Every call it takes comes back to you as a lead, and your own phone stays exactly as it is.

Not sure? We set it up either way, and you can change it later.

$39,252
Estimated saving in year one

Receptionist cost is an estimate, not a quote: the US median wage for receptionists is $37,230 a year (BLS, Occupational Outlook Handbook, May 2024 data), and base salary is typically 55–80% of the true cost of employing someone once payroll taxes, benefits, equipment and cover are counted. The two columns are not like-for-like — a full-time hire covers business hours, while the AI plan shown covers nights, weekends and holidays within its included minutes. Your own cost will differ.

FAQ

Common Questions

What exactly does CallSide AI do?

CallSide AI is a 24/7 AI receptionist for your business phone. It answers your calls day and night, asks the caller what they need, captures their name, number and appointment request, and sends the lead straight to you. AI website chat is available as an optional add-on for visitors who would rather type than call.

Is this an AI phone receptionist?

Yes — that is the main product. The AI receptionist answers your business phone line 24/7, speaks with the caller, and captures their details and appointment request. Website chat is a separate optional add-on that works on your website only; it does not take phone calls.

Does it replace my office staff or dispatcher?

It can replace much of the repetitive call-handling work for many businesses, or work alongside your existing team for after-hours, overflow, weekends and busy periods.

Can it quote pricing?

Yes, at a general level, using only pricing rules and information approved by your business.

Can it book confirmed appointments?

It always captures the appointment request — the service needed, the address and when the customer is available. Whether it writes a confirmed slot into your calendar depends on your setup: if you use Google Calendar, Outlook or a CRM we can connect to, we set that up and it books directly. If you don't, the request comes to you by email and your team confirms it. We tell you which of the two you're getting before you sign up.

Can it connect to my scheduling or dispatch software?

Every lead is delivered by email the moment the call ends — that works no matter what you run. Beyond that we connect to Google Calendar, Outlook, and to systems that accept an incoming webhook or have a Zapier or Make connector, which covers Jobber, Housecall Pro, Workiz and ServiceTitan among others. Tell us what you use on the demo call and we'll confirm exactly what's one-way and what's two-way before you commit.

What happens when it can't answer a question?

It lets the caller know their question will be passed along, and captures the inquiry for your team to follow up.

Can we approve and change its answers?

Yes — all answers are built from information your business reviews and approves.

How is it set up?

You keep your number: it stays with your carrier, in your name, and you set call forwarding so calls reach the AI receptionist when you can't pick up. Nothing is ported and you can switch the forwarding off yourself in about thirty seconds. If you add website chat, it is a short snippet of code on your existing site — no rebuild required.

What customer information does it collect?

Typically name, contact details, service needed, and preferred timing — only what's needed to follow up.

Will it sound robotic?

Callers are told at the start that they are speaking to an AI assistant, because pretending otherwise damages trust and in some states it isn’t permitted. You choose the name and voice and approve the script before it goes live, and if you don’t like how it sounds we change it.

What happens if it fails or goes down?

Calls reach the AI through forwarding rules that you control, so if anything goes wrong the fallback is the behaviour you already have today — the call follows the forwarding rules you already have, to your mobile or voicemail. We monitor the service and aim to respond to issues within one business day, and you can disable forwarding yourself at any time without waiting for us.

Am I locked into a contract?

No. Monthly plans are month to month and you can cancel any time. Your first month's subscription is covered by the 30-day money-back guarantee.

Who is behind CallSide AI?

CallSide AI is an independent company focused on one thing: AI reception for home-service businesses. We are not a reseller and we are not a large call centre — when you contact us you reach the people who actually build and run your setup. Read more about us.

How quickly can it be launched?

Most businesses are live within a few days of providing their business details.

Can it handle sudden call spikes?

Yes. AI receptionists can handle multiple calls at the same time, which helps reduce missed calls during busy periods.

Does it know the difference between a tune-up and a no-cool call?

It asks and then labels the lead accordingly, so your urgent no-heat and no-cool calls are not buried under maintenance requests.

Can it collect equipment details before the truck rolls?

It asks for system type, approximate age and the symptom, and puts them in the summary so your tech arrives informed.
