How does carl know what a variation is and what the order covers?

From your schedule of works. carl knows the scope that was ordered and spots it when something gets reported that isn’t in there. In case of doubt he asks instead of deciding for himself.

Can carl make sure only someone with the right licence drives?

Yes. Qualifications, certificates of competence and expiry dates are held against each person. carl only asks the people who are actually allowed to take the job, and flags it when a certificate is running out.

We run several trades. Can carl tell them apart?

Yes. Every trade has its own qualifications, its own processes, its own contacts. carl plans per trade and still holds them together on a shared site.

What happens when there’s no signal on site?

The message goes out as soon as there’s reception again. Your fitter writes it whenever it suits. carl still files it against the right time and the right project when it lands.

Do the recorded hours make it into our payroll?

carl hands them over to your system: DATEV, Lexware or your trades software. You check and approve as before, just without typing up the paper slips first.

What if the customer calls the fitter directly?

The fitter doesn’t have to promise anything. He passes the request on to carl in one line, carl attaches it to the right site and gets the decision from the office. The customer gets a binding answer, without anyone shuttling between the site and the phone.

Half of our people don’t speak German. Is that a problem?

No. carl writes to everyone in their own language and translates the answer back for the office. For the fitter nothing changes except the language in the chat.

carl for trades — lets the day run | nnexoro

carl does the work between the work. He staffs crews, briefs fitters and informs clients. The AI colleague between office and team.

I bring
the site
into the office.

Measurements, hours, variations: carl records what happens on site and files it where your office needs it. Your fitters go back to fitting. The evenings buried in paperwork are gone.

What carl takes on

Request a consultation

Three places, one thread. carl picks it up on site, turns it into a record in the office and keeps your customer up to date. No group chat, no chasing people by phone.

The site writes the way it talks

A photo, a voice note, two lines on WhatsApp. carl asks for whatever is missing: measurements, hours, material — and nobody has to learn a new app.

The office gets a proper record

The message turns into data: hours booked, variation raised, daywork sheet filed. In your system, with nothing retyped.

The customer hears from you before they ask

Appointment, delay, approval for the variation: carl keeps the customer in the same thread and documents the sign-off so it holds up later.

reports what happens

books it and files it

knows where things stand

You’re not short
of work.

You’re short of hands. And a good part of the hands you do have spend their day on coordination instead of the trade. That’s exactly where your business wins time back.

WhatsApp, Excel, a shout across the yard: the information is there. It just never finds its way. carl carries that layer.

He knows a variation from a daywork sheet, writes into your systems and keeps pace without ever stopping the job.

The situation

Your systems

A variation, from the shout on site to the invoice

Swapping the radiator was the job. On site the pipe turns out to be leaking — that isn’t in the order. One line in the chat is enough, and the variation is evidenced before the wall goes back up.

carl logs the extra work

Not in the schedule of works. One line in the chat does it.

carl, something else here. Pipe is leaking, not in the spec. Has to be replaced too.

carl locks in the site and the timestamp

The variation is raised. Next he needs the evidence.

Got it. Variation on Lindenstraße 14, 14:22. Send me a photo of the damage.

carl gets the evidence off the site

The pipe is photographed before the wall goes back up. Without a photo, the variation turns into an argument later on.

Photo · Pipe damage

carl asks for time and material

One hour, one fitting. That’s all the invoice needs.

Thanks. Estimated effort?

carl turns one line into the variation

The fitter writes five words. carl adds the rest.

approx. 1 hour + fitting

carl prices labour and material

DN20 fitting is in stock, price from the price list. The fitter doesn’t have to work anything out.

carl checks stock and price list

DN20 fitting is in stock, 2 of them. With one hour of labour, your price list puts it at 148 € net. Shall I send that to site management for approval?

carl gets the approval from site management

Site management has approved. The fitter can give the customer the price.

carl messages site management

Variation is with site management: DN20 pipe leaking, not in the spec, 148 € net. I’ll come back to you the moment it’s approved.

The variation is settled with site management

A reminder for the invoice is set. The fitter carries on working.

carl updates site management

Site management has approved. You can quote the customer 148 € net. The variation is documented.

Job from email, ERP or the office

New job in. carl puts the crew together.

carl reads location, time window and the qualification needed, matches them against availability, asks suitable fitters all at the same time and writes the job into the calendar as soon as you approve it.

Sick note in the chat

Someone drops out. carl asks everyone for cover at once.

carl logs the message, checks qualification, driving licence and distance, asks suitable people all at the same time and keeps the foreman and the customer posted. You decide who drives out.

End of the day on site

The scrap of paper in the trouser pocket becomes a timesheet in the system.

carl asks for hours, material and a photo, assigns it all to the right project and files the finished record where the office expects it. Not at the end of the month, but on the same day.

Unplanned extra work

Extra work is documented before anyone forgets it.

carl logs the message, attaches a timestamp and a photo and pushes it straight to site management, instead of it fizzling out in a WhatsApp group where nobody remembers it at invoicing time.

Service due or breakdown

Maintenance jobs report themselves. The call-out finds the one who picks up.

Maintenance that falls due comes up on its own, carl bundles it by area and books the customer appointments. In an emergency he asks the on-call rota and sends plant history and access details straight along with it.

Application by WhatsApp

The application arrives at 21:40. The answer at 21:41.

carl replies straight away, asks the questions you would otherwise ask on the phone and suggests a time. Once they accept, he walks them through documents, contract and safety briefing until the file is complete.

carl knows the difference between a measure-up and a variation

A generic system asks you what a daywork sheet is. carl doesn’t. He knows the terms, the roles and the exceptions of your trade and writes them down the way your office needs them.

Daywork sheet

F-gas certificate

Service contract

Delay notice

On-call rota

Measurement sheet

One word, a whole chain

Log the sick note · cancel appointments · ask for cover · tell the foreman and the customer

Log the report · secure photo and timestamp · inform site management · set a follow-up

Ask for hours · record material · write the report · tell the customer it’s finished

Fitter / journeyman

Site management

Office & accounts

Gets complete hours and reports ready for invoicing, instead of deciphering scraps of paper at the end of the month.

Customer & property manager

Asks whether somebody is coming today and gets the answer, without anyone in the office having to pick up the phone.
