Sources and methodology

Figures without the sales fog.

Here are the figures we use in our installer emails and on /en/installers, with source, date and assumptions. We work from industry research and never present an average as a promise for a single company. Some numbers are directional, others are worked examples; that is noted per row in the methodology column. No sales fog, no polished percentages without context. Objections from email 4 are worked out separately on /en/installers/faq.

manual quote building is still common at installation companies.
Uw Duurzame Installateur, offertes sneller maken Accessed May 2026 Used as qualitative support for process pain; not as a market-wide percentage.

Industry vs. company

Industry averages are context. We use them to create recognition, not to suggest that every installation company has exactly the same loss or the same gain.

Worked examples

When we convert time savings, we show the underlying assumption. For example: 10 technicians, 4 jobs a day and 10 minutes less admin per job.

No guaranteed results

The figures show where the pressure sits and where automation can help. Results depend on process, data, discipline and implementation.
