Job sheet App: create, schedule and invoice digital job sheets

Digitale werkbon app op desktop, tablet en smartphone — Simple-Simon werkbonnen software

The smartest way to go paperless, both in the office and on the road.

Lost paper job sheets, re-entering hours from your phone at the end of the day, and calling customers back for a signature. For many field service businesses, that’s part of everyday work, adding an average of 3 to 6 minutes to every job sheet.

Simple-Simon’s job sheet app replaces this process with digital job sheets that your field engineers complete directly on their smartphone or tablet. Your office team sees every update in real time, and as soon as the job is finished, the invoice is ready. No duplicate data entry, no missed hours, and no delayed invoices. Thanks to direct integrations with accounting software such as Exact, and WeFact, all data is synchronised automatically.

Perfect for field service businesses with mobile teams. Also the ideal job sheet app for freelancers.

What is a digital job sheet?

A job sheet is the document used to record what was completed during a job: which tasks were carried out, which materials were used, and how much time was spent. A digital job sheet is the electronic replacement for traditional paper job sheets. It contains everything needed for a job, including customer details, the job address, the work to be completed, the required materials, and the scheduled time.

With Simple-Simon, digital job sheets are accessible from smartphones, tablets, and desktops, giving both office staff and field engineers access to the same up-to-date information.

No more lost job sheets, unreadable handwriting, or delays between the field and the office. Everything is stored in one central system and updated in real time.

What are the benefits of the job sheet app?

No more paper job sheets

Your field engineers complete digital job sheets on their smartphone or tablet while they’re still on-site. No more unreadable handwriting, lost paperwork, or piles of job sheets waiting at the office. Customers sign directly on the screen, and the completed job sheet is instantly available in the system.

Real-time visibility of your field operations

See the status of every job sheet at any time. Track hours worked, materials used, and whether a job has been completed. With the digital planning board, you always have a live overview of your field team without having to make a single phone call.

Faster invoicing through your accounting software

As soon as a job sheet is completed, you can generate a draft invoice immediately. Simple-Simon integrates with Business Central, Exact Online, WeFact, Moneybird, and more than 70 other accounting systems. Customer data, products, and hourly rates are synchronised automatically, so there’s no need for duplicate data entry.

Keep everyone informed without making phone calls

Every planning change shouldn’t have to end with a phone call or WhatsApp message. Your field engineer calls the office, the office calls the customer, and valuable time disappears without ever being billed.

With Simple-Simon, your field engineers see planning updates instantly in the app. Customers automatically receive a confirmation, and every engineer has access to customer details, job history, and previous work before arriving on-site. Meanwhile, your office team can see in real time whether a job is in progress or completed—without picking up the phone.

Work more sustainably

Stop printing, storing, and archiving paper job sheets. By going digital, you reduce paper usage, cut down on administration, and create a more sustainable workflow without increasing costs or spending extra time.

How the job sheet app works in 4 simple steps

 

Step 1: Create and schedule a job sheet

Create a new job sheet in the office module and schedule it on the digital planning board. Creating a digital job sheet in Simple-Simon takes less than a minute. Enter the customer details (or select an existing customer), describe the work, and add materials, checklists, or forms if needed. Link the job to a customer, asset, or project, assign it to a field engineer, and the job sheet instantly appears in their app.

 

Step 2: Complete the job in the app

Your field engineer opens the job sheet app on their smartphone or tablet. They can see all customer information, the job description, and any required checklists or safety forms. During the job, they record hours, materials used, and photos. Once the work is finished, the customer signs directly on the screen.

 

Step 3: Stay in control from the office

Track the status of every job sheet in real time. See which jobs are in progress, which have been completed, and whether any issues need attention. Time tracking and material tracking are updated automatically, so your administration is always up to date.

 

Step 4: Invoice immediately

Once the job is completed, generate an invoice directly from the completed job sheet. Thanks to the integration with your accounting software, everything is transferred automatically—no manual data entry, no missing information, and no duplicate administration.

What is the difference between a job sheet app and job sheet software?

A job sheet app is the mobile component—the app that field engineers use on their phone or tablet while working on-site. Job sheet software is the complete solution, combining the mobile app with the office module used for planning, managing jobs, and invoicing.

Simple-Simon provides both: the job sheet app for field engineers and the office module for planners and office staff. Together, they form a complete digital job sheet solution for field service businesses.

What is the difference between a job sheet app and digital job sheet?

The job sheet app is the software you use, while a digital job sheet is the end result – the completed job sheet created through the app. You use the job sheet app to create, schedule, complete, and share digital job sheets.

Does the job sheet app work without an internet connection?
Absolutely. Field engineers don’t always have a stable internet connection while working on-site. That’s why the Simple-Simon app also works offline. As soon as an internet connection is available again, the app automatically synchronises all data.
