The problem
A damage charge letter that's vague or sharp-toned gets disputed, and disputes take hours of calls and emails. A hire firm sending 8 damage, fuel or late-return letters a month, spending 45 minutes on each, spends 6 hours a month writing them, and still loses some charges because the letter didn't explain the basis.
What the AI does
Write the facts for each case: the clause in your agreement, the photos from pickup and return, the repair quote and what you're charging. Paste them into ChatGPT, Claude or Gemini without the hirer's name, address or license details, and ask for a short, polite letter that sets out the damage, the evidence, the cost and how to pay or dispute it. Check every figure and clause against your agreement and the quote, then send it from your own email with the photos attached.
A worked example
A van hire firm in Bradford sends about 8 damage, fuel and late-return letters a month. The owner drafts each from anonymised notes with an assistant, checks it against the agreement and attaches the photos.
Before
About 45 minutes per letter, 8 a month: 6 hours, and frequent disputes about the basis of the charge
After
About 15 minutes per letter including checking: 2 hours
What it's worth
About $80£60€71A$115C$113 a month in time: 4 hours saved at an assumed $20£15€18A$29C$28 an hour, against free to about $27£20€24A$38C$38 a month for the assistant. Charges recovered because the letter is clearer aren't counted.
How to set it up
- Gather the agreement clause, the pickup and return photos, the repair quote and the charge.
- Remove the hirer's name, address and license details before pasting anything into the assistant.
- Ask for a short, polite letter that states the damage, the evidence, the cost and how to pay or dispute it.
- Check every figure and clause against your agreement and the quote, and correct anything the assistant invented.
- Send it with the photos attached and keep a copy with the hire record.
What goes wrong
- An assistant may quote terms your agreement doesn't contain. Use your actual wording.
- Charges must reflect the real cost of the repair and be fair to consumers. An inflated charge is hard to defend.
- Free assistant plans may use what you paste to improve their models unless you turn that off. Keep personal details out.
