    Thank you - the stopcock is under the sink.

What she does

One missed call is one missed job

Six moments every service business knows. Here is what she actually says in each one.

The calls you cannot get to

Both hands busy, phone in your pocket. She picks up on the second ring.

Is that Hendry Plumbing?

It is. Dave's on a job - I can help. What's happened?

After you have shut

Half your enquiries land after six. She works the hours you do not.

Sorry, I know it's late - are you open tomorrow?

We open at eight. I can book you in for the morning now if you like.

Booking, not message-taking

She reads your real diary and writes the appointment in.

Have you got anything Thursday?

Thursday at 9, or half past 2. Which suits you better?

Changes and cancellations

The admin that eats your evening, handled on the call.

Something's come up, can we move Friday?

No trouble. Same time Monday, or Tuesday at 4?

The one that cannot wait

A leak is not a message. She puts them through and texts you.

There's water coming through the ceiling.

I'm putting you through to Dave now, and texting him the address.

The right person, not just a time

Five diaries on Team. She knows who does what, and on which days.

Can I get my brows done with Kayleigh?

Kayleigh does brows Tuesdays and Thursdays. Tuesday at 11?

The difference

Everyone else takes a message. Brenda books the job.

She reads your diary, your working hours and your calendar, finds a slot that genuinely exists, and writes the booking in - before the caller hangs up.

Incoming call

Kirkstall Tyre & MOT, Thursday 9:04am

  1. Caller

    Morning. I need an MOT before the end of the month.

  2. Brenda

    No problem. Can I take the registration?

  3. Caller

    Yeah, it's LV19 KHZ.

  4. Brenda

    Got it. MOT is £54.85 and takes about an hour. I've got Thursday at 9, or Friday at 2 - which suits?

  5. Caller

    Thursday at 9 is grand.

  6. Brenda

    So that's an MOT, Thursday the 23rd at 9am, for the LV19 KHZ. Is that right?

  7. Caller

    That's it, yeah.

  8. Brenda

    Booked. You'll get a text confirming in a moment.

Written to the diary and to Google Calendar. Confirmation text to the caller, summary text to the owner.

She read the booking back and waited for a yes before writing anything. That check is not optional and cannot be turned off - it is how you get zero wrong bookings.

Who it is for

Built for businesses that live by the diary

If a missed call means a missed appointment, this is for you.

Home services and trades

You are under a sink with both hands wet. The phone rings out and the caller tries the next plumber on the list. Brenda answers, prices the job from your own website, and books it while you carry on.

Salons and beauty

Mid-colour, gloves on, and the desk phone is going. A missed call is a missed chair and an empty hour you cannot sell twice. Brenda picks up, finds the gap between clients, and pencils them in.

Auto service

You are under a car with the radio on and the office is empty. The MOT booking goes to the garage down the road instead. Brenda takes the reg, quotes the MOT, and puts it in the bay diary.

Clinics

You are with a patient and cannot break to answer. New patients rarely leave voicemail, they simply ring another clinic. Brenda books the assessment and leaves the notes on your desk.

Consulting and professional

A prospect calls during your one deep-work block of the day. Miss it and the enquiry cools before you ring back. Brenda screens it, takes the detail, and offers a slot from your real calendar.

Law firms

New client intake happens on the phone, and it happens once. Callers with a deadline do not wait for a call back. Brenda captures the matter, checks for conflicts of interest by name, and books the first appointment.

Real estate and lettings

Viewing requests arrive in bursts, mostly while you are already at a viewing. Every unanswered one is a buyer looking at somebody else's listing. Brenda books the viewing against the right negotiator's diary.

Any small business

If a missed call means a missed appointment, Callso fits. You tell Brenda what you sell, how long it takes and when you work. She does the rest, in your own words.

Yours not listed? Have a look at a trade page - the engine is the same for all of them.

Setting up

Live before your next brew goes cold.

  1. 12 minutes

    Give her your website

    She reads it and comes back with your services, your prices, your areas and your hours - written out, for you to correct. No website? She asks you ten multiple-choice questions instead.

  2. 22 minutes

    Divert your phone to her

    You keep your own number. Dial one short code on your phone and calls come to her - all of them, or only the ones you miss, or only after hours. We show you the exact code for EE, O2, Vodafone and Three.

  3. 31 minute

    Connect your diary

    Google Calendar or Outlook, one tap. Now she can see your real gaps, and book into them. On Answer she just takes the details and texts them to you instead.

If Callso ever goes down, your calls forward to your mobile and ring exactly as they did before. The fallback sits at the phone network, not in our software.

The maths

What are missed calls actually costing you?

What do you do?

Picking a trade fills in typical numbers. They are our starting guesses, not a study - drag them to yours.

£4,680

a month, to a ringing phone.

Brenda answers every one of those calls and takes the details, from £39 a month. To book them straight into your diary it is £79.

Start with Answer, £39

12 missed calls a week, 50% of them ringing the next business, at £180 a job. That is the whole sum - no fine print.

Pricing

Start with Team

Every new account starts with Brenda asking your permission before she does anything - bookings, emails, quotes. You loosen that yourself, when she has earned it. Go past your calls for the month and we tell you before anything is charged - it is 25p a minute after that, and we will point you at the plan that costs you less.

Questions

The things people ask before they sign up.

Will my customers know it is not a person?

She says she is an assistant if she is asked, and she never pretends otherwise. Every call opens by telling the caller it is recorded - that line is part of the greeting and cannot be removed. Most callers just want their MOT booking and a straight answer.

How does she know anything about my business?

You give her your website address. She reads it - your services, your prices, your areas, your hours - and shows you a draft of what she learned. You correct anything that is wrong and approve it. If you have no website, she asks you about ten multiple-choice questions instead.

What if she does not know the answer?

She says so. 'I'll get Dave to confirm that for you' - then she takes the caller's details and drafts you an email reply to approve. She does not guess at a price, ever. Inventing a number is the one thing we treat as a failure.

What happens if your system goes down?

Your calls forward to your mobile, exactly as they did before Callso, and you get the missed-call text as normal. The number is yours and the fallback lives at the phone network, not in our software - so if we break, the phone still rings. Nobody ever gets dead air.

Do I have to change my phone number?

No. You keep your number and divert calls to the one we give you - all calls, or only when you are busy or closed, whichever you pick. It is a short code you dial once on your own phone, and we show you the exact one for EE, O2, Vodafone or Three.

Can she book into my actual calendar?

Yes, on Book and Team. She connects to Google Calendar or Outlook, reads your real availability - your hours, your holidays, your existing appointments, the buffer you want between jobs - and writes the booking to both your diary and your calendar.

What if she books something wrong?

She reads the date, time and job back to the caller and waits for a yes before she writes anything. On top of that, every booking lands in your approvals inbox for a tap, until you tell her she can go ahead without asking.

How long does setting up take?

About twenty minutes, most of it you reading what she has learned about your business and correcting the bits she got wrong. The number, the diversion and the calendar are a few minutes each.
