−6 h paperwork per technician per week
Industry: construction & installation
Construction: from paper job sheets to invoiced hours.
Every minute worked belongs on an invoice, not on a slip of paper in the van. We build websites that bring in quote requests, job sheet apps technicians use offline and scheduling software connected to Exact, AFAS or Bouw7. Tangible time savings, no digital transformation.
Platform
— Construction & installation
Website, field service app and software development for construction and installation
A quote request through the website that gets an answer after 4 days goes to the competitor who sends a price indication within the hour. Paper job sheets, photos in WhatsApp and hours filled in from memory on Friday mean invoices that go out late and change orders that never get billed. Only 40% of the Dutch installation trade has digitized planning and work preparation, while profits fell 11% on average in 2025.
RABZI builds what a construction or installation company actually uses. A website with pages per service and per town and a quote configurator for solar panels, heat pumps or dormers that returns an instant price indication and a PDF quote. A job sheet app that works offline, with photos, signature, hours and materials, connected to Exact, AFAS or Bouw7. A client portal with progress, compliance file and change order approval.
No 12-month ERP project: we build around your existing software and go live in weeks. Fixed price, fixed date, and you talk to the maker, on site if that is what it takes.

— Sound familiar?
Construction & installation: what we see.
Quotes take days and leads from Werkspot keep waiting
We build a quote configurator and AI lead qualification that answer requests within minutes with a price indication, so you respond first and your estimator only calculates serious jobs.
Paper job sheets, photos in WhatsApp, hours logged afterwards
We build a job sheet app for technicians that works offline, with photos, signature, hours and materials, connected directly to Exact, AFAS or Bouw7, so a finished job becomes an invoice the same day.
Scheduling technicians and materials in Excel
We build a planning board with real-time progress, hours versus budget and material orders at Technische Unie via 2BA/ETIM, so work preparation steers on margin instead of gut feeling.
Compliance files and snag lists scattered across email and folders
We build a client and project portal that holds the Wkb file, inspection reports, snag lists and change order approvals per project, so at handover nothing has to be pieced together and no repair round is needed.
A website that does not pull its weight
We build a site with local pages per service and town, a project portfolio and a quote flow that fits your work, so “heat pump installer + town” lands on you instead of the national lead reseller.
No view of margin per project
We build a dashboard with margin per project, hours versus budget and outstanding invoices, fed from your job sheets and accounting, so on Friday you know which job makes money.

— Our approach
How we approach it.
-
01
We walk the job with you
Before we draw anything, we follow how a job sheet travels from the technician to the invoice today. That is where the hours go missing, and that is where the design starts.
-
02
Around your existing software
Exact, AFAS, Bouw7 or Syntess stay in place. We build the app, the portal or the configurator that connects to them, instead of forcing you onto a new package.
-
03
Built for gloves and bad coverage
Big buttons, offline storage, photos that sync later. A technician has to be able to use the app in a crawl space, or the paper comes back.
-
04
Live in weeks, no ERP project
A website takes 3 to 6 weeks, a job sheet app or configurator 8 to 16. We start with the 20% of features that remove 80% of the paperwork and build on from there.

— Frequently asked questions
Questions about construction & installation.
01How much does a website cost for a contractor or installation company?
A website with pages per service and town, a project portfolio and a quote form starts from €4,950 excl. VAT and goes live in 3 to 6 weeks. A quote configurator or client portal starts from €12,500, a job sheet app for technicians from €15,000, custom scheduling software from €12,500. You get a fixed price and a fixed date up front; anything you want added later is billed at €115 per hour.
02How long does it take to build a field service app?
A job sheet app with offline sheets, photos, signature, hours and materials, connected to your accounting, is in the hands of the first technicians in 8 to 12 weeks. With scheduling, stock and a client portal, count on 12 to 16 weeks. We start with 2 or 3 technicians who test the app on real jobs for a week, process their feedback and then roll out to the whole team.
03Can you integrate with Exact, AFAS, Bouw7 or Syntess Atrium?
Yes. We connect job sheet apps, configurators and portals to Exact Online, AFAS, Bouw7, Syntess Atrium, Outsmart, 12Build, Simplicate and Moneybird, and to 2BA/ETIM product data and the Technische Unie online store for materials. We also pull Kadaster and BAG property data automatically from an address. If you work with a package not on this list, we check up front whether an API or export is available.
04What is a quote configurator for solar panels or heat pumps?
An online tool on your website where a customer enters their address, roof area or energy use and immediately gets a price indication, including a subsidy estimate and a PDF quote in your brand. Roof and address data come from BAG and Kadaster, prices from your own calculation sheet. You get a qualified lead with everything the estimator needs; the customer gets an answer within a minute instead of after 4 days.
05Does your software help with the Dutch Quality Assurance Act (Wkb)?
Yes. In the project portal we build up the Wkb file per project: photos per construction phase from the job sheet app, inspection reports, material certificates, snag lists and the customer’s sign-off, all with date and time. At handover you export the consumer file and the file for the authorities with one click, instead of piecing everything together from email, WhatsApp and folders.
