What is a digital job sheet and how does it work with AI?

What is a digital job sheet?

A digital job sheet is a job sheet you fill in on your phone or tablet, instead of on paper. Your fitter or tradesperson records on site what he has done: the hours, the materials, photos and any extra work. That data then goes straight to the project, without anyone in the office having to retype it.

With a paper job sheet, it goes differently. The sheet travels in the van, arrives at the office at the end of the week and is then retyped into the administration. Sometimes it is illegible, sometimes a signature is missing, and sometimes it is still lying under the seat. Does that sound familiar? Then also read you retype the same data.

What goes on a job sheet?

A job sheet states what was done on a job, by whom and for how long. The exact fields differ per company, but they usually include:

• Project or customer. Name, address and the project number.
• Date and hours. Who worked, and for how many hours.
• Work carried out. A short description of what was done.
• Materials. What was used from the van or the warehouse.
• Extra work. Work that was not in the assignment and is invoiced separately.
• Photos. Of the situation before and after, or of a problem.
• Customer approval. A signature or an approval on the screen.

Extra work in particular often gets lost on a paper sheet. On a digital job sheet you can tick it separately, so it is not forgotten on the invoice.

Why are companies switching from paper?

Companies switch because the data then ends up in one place, at the moment the work is done. That has a few consequences:

• The office no longer has to retype the sheet. That saves work and typing errors.
• Hours and materials are in the administration sooner, so you can invoice sooner.
• Photos belong to the project, not in a chat group or on someone's phone.
• You can see per project how many hours and how much material went into it, also for the post-calculation.

There is also a downside. Your people have to learn a new habit, and an app that does not work well on the building site is quickly put aside again. That is why it is important that filling it in takes as little time as possible.

How does a digital job sheet work with AI?

With AI, a fitter can dictate his job sheet instead of typing it. After the job, he says in a few sentences what he has done. AI turns that into a job sheet, with the fields in the right place. The office then checks it.

AI is good at this because it can convert spoken language into fixed fields. It can also read a photo of a paper job sheet, with a technique called OCR. Handwriting remains more difficult, so doubtful cases go to an employee.

AI can make mistakes. It can mishear a number or add something that was not said. This is called a hallucination. That is why AI makes a draft, and a person approves the job sheet before the hours are in the administration.

Want to see what that looks like? On AI op de bouw (in Dutch) there is a video of a job sheet being dictated and approved at the office.

Off-the-shelf job sheet app or custom?

For many companies, an off-the-shelf job sheet app is a good start. There are various apps for sale, often as a subscription per user. Such an app is called SaaS: software you rent and use over the internet.

A custom job sheet makes sense if an off-the-shelf app does not fit well. For example:

• You work with your own project numbers, hour types or rates that the app does not recognise.
• The job sheet has to go to a system the app does not support.
• You want your people to be able to dictate it, with AI.
• You already have a system for scheduling or projects, and the job sheet has to fit into it.

Software made to measure is also called custom software. It costs more to make than a subscription, but you do not pay an amount per user and it fits exactly with how you work. Which route suits you depends on your systems and your people.

How do you connect the job sheet to your administration?

A digital job sheet helps most when the data flows through automatically. That works with an integration: software that brings data from one system to another. Many accounting and project packages have an API for this, a fixed entry point for other software.

A good chain looks like this:

1. The fitter fills in the job sheet or dictates it.
2. The job sheet goes to the right project.
3. The office approves it.
4. Hours and materials go to the administration, extra work to the invoice.

Every step that happens automatically is a step in which nobody has to retype anything. You can read more about automating such steps in workflow automation.

What should you look out for with a digital job sheet?

Look mainly at ease of use on the building site, and at agreements about data. Specifically:

• Quick to fill in. Ask only for what you need. The fewer fields, the more often the job sheet gets filled in.
• Working without signal. In a basement or on a new-build site, the signal is sometimes poor. Ask whether the job sheet still works then and sends later.
• Customer approval. Decide whether you want a signature on the screen, or an approval by email.
• Personal data. A job sheet contains names and addresses. Agreements apply to that, such as a data processing agreement with the supplier or developer.
• Who owns the data? Make sure you can take your job sheets with you if you ever switch.

What does a digital job sheet cost?

That depends on the route. An off-the-shelf app is usually paid per user per month. A custom job sheet, connected to your own systems, is a one-off payment for the build, followed by a fixed monthly amount for hosting and maintenance.

What a custom job sheet costs depends mainly on the number of systems it talks to, such as your scheduling and your accounting, and on how many types of work need to go into it. With me, it starts with a business analysis. In it, I look at how you work now, in the office and out on site. Then you get a proposal with a fixed price, so you know in advance where you stand. Also read how your price is determined.
