ConceptA tool I would build. Not client work.
Quote builder for trades
Quotes get written at night from a price list in a spreadsheet. Sometimes one goes out under cost, and you find out when the job is done.
Concept
Not client work- What this is
- A tool I would build, drawn to show the idea. Nobody has bought it, and every name and number on these screens is invented.
- For
- An installer or contractor who quotes from a price list in a spreadsheet.
- The money
- No figure I can stand behind. The money is in two places you can count yourself: the evenings spent writing quotes, and the ones that went out under cost.
- Belongs to
- Internal tools
- Drawn

What it would be worth
Quotes written in the day, at a margin you meant.
A quote that takes twenty minutes instead of an evening, built from one price list, with the margin in front of you while you write it.
Time your next three quotes from the measuring to the send. Then look at the margin on your last twenty.
What you can buy today
- PandaDoc (opens in a new tab)$19 to $49 per seat a month
- Qwilr (opens in a new tab)$35 to $75 per user a month
List prices as each vendor’s own page showed them on 11 Nov 2026. Both make good-looking quotes. A custom builder is the better buy when the hard part is your measurements and your price list, not the layout, and you want the margin checked before anything leaves.
Time spent writing quotes, in euros
Type your numbers and the sum appears here.
This is the time, not the margin. For the margin, look at your last twenty quotes and count the ones that went out under the floor you meant to keep. Your numbers stay in this tab.
Where the line is
It does the sums. You set the price.
What it does
- Builds every line from your own price list and the measurements you type.
- Shows the cost and the margin while you write, and never puts either on the customer’s PDF.
- Turns the margin amber under the floor you set, before the quote can leave.
- Sends the quote to sign, and tells you when it is opened and signed.
What it never does
- Change a price, add a line or give a discount on its own.
- Send a quote without a person pressing Send.
- Guess a measurement. If one is missing, the quote waits for it.
The price list stays yours: import it from your supplier’s file or keep it by hand. VAT and the rules around it are your accountant’s call, not the tool’s.
Want this for real?
I would start with a week on your real price list and your last twenty quotes: which lines repeat, which measurements drive them, and where the margin slips. Then a fixed price.
I would scope it as an internal tool: from €18k, usually 3–5 weeks, at a fixed price.
