How window installers save 4 hours per quote

"Building the quote is the easy part. It's the chasing, the corrections, the re-sending that kills my evenings." That's a direct quote from a window installer we talked to last month. Below: where the time actually goes, and three changes you can make this week to cut 4+ hours per quote.

Where the 4 hours hide

We logged time across 30 sample quotes from 6 different installation businesses (2-15 employees). Average time from first customer contact to signed approval: 7.2 hours. Industry benchmark for streamlined operations: under 3 hours.

The gap breaks down like this:

• 45 min — building the initial quote in Excel (looking up prices, applying VAT, formatting)
• 20 min — converting to PDF and emailing
• 30 min — chasing the customer for confirmation (3-4 follow-ups average)
• 40 min — handling the revision request ("can you make the entrance door wider?")
• 15 min — re-creating the corrected quote
• 25 min — sorting out down-payment via separate bank-transfer request
• 1.5 hours — administrative pickup later (filing, invoicing, accounting export)

Three changes that recover 4 hours

1. Replace Excel with a configurator

Building a quote from scratch every time is the biggest time-thief. A configurator (whether it's Kozynofferte or a competitor) with your product catalog pre-loaded turns 45 minutes into 5. Total monthly saving for 3 quotes/week: ~9 hours.

2. Use a customer portal with e-signature

Chasing customers via email loses both time and conversion. Studies show that quotes sent with a single-click "approve and pay" link convert ~30% better than email-only quotes. Plus you save 30+ min per quote on follow-ups.

3. Built-in down-payment via online payment

Sending separate bank-transfer requests for the deposit costs ~25 min per quote and adds 2-5 days to your cash-flow cycle. With iDEAL or SEPA at the moment of approval, you have the deposit before the customer logs off their device.

What this changes for a 4-person window business

Take a small business: 3 quotes/week, €60/hr loaded sales rep cost. The 4 hours/quote saving = €720/month in pure labour cost. That's before counting improved conversion or faster cash-flow.

For an 8-person business with 8 quotes/week: ~€2,000/month in recoverable labour. That funds an entire SaaS stack and a part-time apprentice.

What you can do this week

1. Time-log your next 3 quotes — note actual minutes, not estimates
2. Identify the biggest sink (usually chasing or re-creating)
3. Pick ONE change to address it (configurator, portal, or online payment)
4. Measure again after 4 weeks. Compare hours, conversion and customer satisfaction
