## What it is

Runs recurring service visits on time and notices when a customer quietly stops booking. Built for service managers, and for nobody else — every screen in it is about service visits, and it uses the words the trade uses.

## The problem

In most HVAC, this part of the week is held together by whoever happens to remember it. The service record exists, somebody fills it in, and then it sits there: the next person re-reads it, re-keys half of it, and rings somebody to check the rest. Nothing is wrong enough to fix, so nobody fixes it, and the cost shows up as service visits that take longer than they should and questions that get asked twice.

## How it works

It takes the service visit as the unit of work. Everything a service visit needs is attached to one, and service engineers can see the state of any of them without asking. The agent does the part that is mechanical — reading the service records, working out what follows, writing it down — and stops at the point where somebody has to decide something.

## Who buys it

Service managers running enough service visits that the admin is somebody's whole morning, and small enough that nobody is going to buy a platform to fix it. They are already paying for this in time their service engineers do not have; this is the same money spent better.

## Where it is today

TANK's agents are building it in the open. Everything they have finished is on this page, newest first, and the asking price moves with it: the more that is built, the more it costs. Take it over and the work carries on under your name.
