A customer rings

Half past three on a Tuesday. Both hands are full. You hear it and you cannot get to it.

Where the money goes

Three leaks.None of them are about the work.

You are good at the job. That was never the problem. The problem is what happens in the twelve hours a day you are not sat at a desk.

The call you never heard

You are up a ladder with a drill going. Three rings and they have moved on to the next name on Google. You never even knew they existed.

What Slate does

Slate texts them back before they finish dialling the next number, and keeps the thread so you can pick it up at five.

The quote that went cold

Two hours pricing it up. Sent on the Tuesday. By Friday you are on another job and you never chased it. It is still sitting in your sent items.

What Slate does

Slate follows it up by text and email on its own, then nudges again for the deposit. You do not have to remember anything.

The nine o'clock shift

Tools down at five, laptop open at seven. Invoices, quotes, chasing money — done tired, done badly, done instead of having a life.

What Slate does

Raise the invoice in the driveway and text a card link before you pull off. Most of it is paid before you are home.

See it work

Stop guessing which postcodesare worth the diesel.

Most firms advertise across the whole city and quietly lose money in half of it. Slate colours in every job you have ever done, so you can see it.

Slate just shows you the answer.

There are no dashboards to configure, no fields to map, no consultant to hire. You do your jobs the way you already do them and the picture builds itself.

Why we built it

Two of us. No call centre.

Slate wasn't built by a software company that ran a survey on the trades. It was built by two people who got tired of watching good firms lose work to voicemail while paying a fortune for a system with four hundred features they never touch.

There is no ticket queue. When you message us, you get one of the two people who wrote the software. If you ask for something sensible, it tends to exist within a fortnight — in the app, not on a roadmap.

We aren't trying to build Salesforce for builders. We're trying to build the one thing you actually open every morning, and nothing else.

Straight answers

The things everyone asks.

If your question is not here, put your number in below and we will answer it properly rather than sell at you.

I am not good with computers. Will I manage this?

If you can send a text message, you can use Slate. There are no settings to configure and nothing to install — it opens in the browser on your phone. We do the entire setup for you on a call, and you carry on exactly as you were, except the phone now gets answered when you can't.

What actually happens when I miss a call?

Am I tied into a contract?

What does the messaging cost on top?

What is the heat map for?

Will it work with no signal in a basement?

Two minutes, no call

Watch it answer a callbefore you speak to anyone.
