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.

Claim	Figure	Source	Date	Methodology note
The technician shortage remains the biggest operational pressure for technical companies.	68% report a technician shortage; 27% cannot fill vacancies within six months.	Installatie.nl / TechBarometer 2025	17-09-2025	The source covers technical companies broadly. We use this as a scarcity indicator, not as an exact segment figure for every installation specialism.
Installers want to hire more technicians in Q2 2026, even as the shortage persists.	77% of installers expect to hire more technicians in Q2 2026.	Techniek Nederland Conjunctuuronderzoek Q2 2026	12-05-2026	Used as industry context for capacity pressure; not a claim that every individual company is growing.
Fast quote follow-up has a direct impact on sales opportunities and customer satisfaction.	83% of clients followed up within 24 hours are open to additional sales, versus 15% after more than a week; waiting a week or longer to respond earns poor marks in customer satisfaction.	Winning Proposal, Snel reageren loont	approx. 10-2024	General quote follow-up data. We use this as directional evidence for speed, not as a guarantee of FlowBaas results.
Quote conversion in the installation sector is under pressure.	-5% quote conversion in Q2 2026 compared with the previous quarter.	Techniek Nederland Conjunctuuronderzoek Q2 2026	12-05-2026	A quarterly snapshot. We link this to process pressure, not to a structural forecast for every company.
Disconnected processes and unclear handovers squeeze margins in the installation sector.	~6% average failure costs as a share of revenue in the installation sector.	Claassen, Moolenbeek & Partners, AI in de installatiebranche	Accessed May 2026	An industry average. Well-organised companies may sit lower; chaotic processes may run higher.
Digital work orders save admin time on every job.	~10 min saved per job (our own assumption; the source only describes the time savings qualitatively); with 10 technicians and 4 jobs a day, that is well over 30 hours per week.	Installatie.nl, digitaliseren van werkbonnen	29-07-2020, accessed May 2026	Both the 10 minutes per job and the 30 hours per week are our own assumptions (worked example: 10 technicians x 4 jobs/day x 10 minutes); the source, an article from July 2020, does not quantify the time savings.
A large share of SME installers still build quotes manually, with information scattered across Outlook, Excel and their ERP.	Outlook + Excel 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. The source is a promotional article by a tool vendor.

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.
