Tested for real
Every prompt ran through ChatGPT and Claude several times before it went live.
Real output included
You can see what the prompt actually produces before you buy.
Pitfalls documented
Where a prompt can go wrong, it is documented in the test report.
Model + date visible
Every prompt shows which model we tested it with and when.
You know these evenings. The job is finished, but the office is not.
01
The proposal has been waiting for three days
The customer wants a number and you want the job. But between measurements and a finished email sits an hour of desk work that never appears during the day.
02
The complaint is sitting in your inbox
One wrong sentence can turn a complaint into a warranty problem or a one-star review. So the reply keeps getting pushed back.
03
Marketing after ten hours on site?
You know project photos can bring in work. Still, they stay on your phone because no one wants to write posts in the evening.
Our approach: We turned the writing work of a trade business into tested prompts. You copy, add your details, and review the result. AI drafts the text; you decide what goes out.

01 · The prompt (full text, free)
Tested ✓Take the role of an experienced estimator in a trade business with 20 years of experience. Create a complete, customer-ready proposal from my bullet points. Context: I own a trade business and have little time for office work. The proposal should sound professional but not stiff, like a reliable local contractor. Work step by step: first structure the line items, then calculate the totals, then write the cover note and terms. If quantities or prices are missing or unclear, ask targeted follow-up questions instead of inventing values. # MY DETAILS: Trade and service: [TRADE AND SHORT DESCRIPTION OF THE SERVICE] Materials with quantities: [MATERIAL LIST WITH QUANTITIES] Working time and hourly rate: [ESTIMATED HOURS AND HOURLY RATE] Special notes: [SPECIAL NOTES, E.G. TRAVEL, DISPOSAL] IMPORTANT: Return the proposal with: cover note (max. 4 sentences), line-item table (item, description, quantity, unit price, total price), net total, VAT, gross total, payment terms, and validity period.

Proposal no. 2026-0142 Dear Ms. Example, thank you for your inquiry. We are happy to offer the bathroom renovation as discussed: Item 1: Removal of existing fixtures (8 hrs at $65) ... $520.00 Item 2: Floor/wall tiling, 24 m2 ... $2,880.00 [shortened]
03 · From our test
Reliably produces a clean line-item structure. The model calculates prices correctly as long as quantities are clear. For approximate inputs, the prompt asks targeted follow-up questions instead of guessing.
04 · Pitfalls no one tells you
- Without your hourly rate in the input, the model invents plausible market rates. Always provide your own.
- Have legal clauses such as warranty and payment terms checked before sending.

Who is behind it
“I test every prompt myself before it is sold.”
Prompthafen is not an anonymous prompt shop. I am Lukas, a software developer, and I have bought too many prompt collections that were obviously never run by anyone. That is why the rule here is simple: no prompt goes live before I have tested it for real, checked the output, and documented the pitfalls. What you buy is something I have used.
