AI on site, when a missing document costs you the job
Write quotes, change orders and reminders faster, yes, but never by letting an AI invent a price or a deadline under your signature.
Carpenter, electrician, plasterer-painter, plumber, tiler: the day is spent on site, and the paperwork waits for the evening. The quote goes out late, the agreed extra stays a handshake, the unpaid invoice waits for its reminder; and the day a client disputes, the written record decides, not the work done.
The point is not to learn one more trade. A framed prompt stands in for the office you do not have: it drafts quotes, change orders and reminders, and the price, the commitment and the signature remain yours.
- Evenings and weekends taken by quotes, invoices and reminders, after full days on site
- Extra work carried out without a written change order, then contested at payment time
- Unpaid invoices chased too late, a claim weakened for lack of a formal demand in due form
- Client names and addresses pasted into consumer AI, beyond your control
See for yourself
A prompt structured in 5 blocks: Instruction · Role and audience · Data · Constraints · Format. An unframed AI invents; the frame stops it.
In a workshop, these prompts adapt to your business, your services and your quote templates, each with its safeguards: no client name ever enters a public AI, and the figure remains your own.
Devis pour client particulier (clair et sobre)
A clean quote, sent the day of the visit, that the client understands without calling back.
See it in Chaptal →Travaux supplémentaires · l’avenant écrit avant l’exécution
The extra agreed on site becomes an accepted document before the first tool comes out.
See it in Chaptal →Facture impayée · mise en demeure et protection de la créance
A formal payment demand in due form, protecting your claim without wrecking the relationship.

« Le Collaborateur, augmenté »
You and your team learn to frame AI on your real documents, quotes, change orders, reminders, without exposing a client.

Your clients compare online before they call; a sober site shows your work and takes in requests on your behalf.

Can AI price my quotes for me?
No. It structures the description, the line items and the conditions; the figure comes from your own cost calculation, and a dedicated catalog card lists what must enter the hourly rate.
Is a formal payment demand written with AI worth anything?
What counts is the content and the form of service: amount, deadline, proof of delivery. The framed prompt imposes these elements; the review and the signature remain yours, and once a dispute hardens, advice from a legal professional remains the rule.
Do I need to be comfortable with computers?
No. The catalog prompts work from a phone, as they are, with no setup. A reply to a WhatsApp request or an incident note can be dictated between two tasks; the AI puts it into shape.
What happens to my clients’ names in a public AI?
Without a data processing agreement, whatever you paste leaves your control. The rule: write “the client”, “the villa”, never the name or the address. Every card in the catalog repeats this safeguard.
Do the documents follow Swiss practice?
The catalog cards are written for Swiss practice: acceptance, defect lists, change orders and reminders follow the trade’s practice, and whatever must be checked with a specialist is marked as such.
