Test “Overdue Invoice Reminder (INR, Indian Etiquette)” with your own key

Paste an Anthropic, OpenAI, or OpenRouter key. It's stored only in your browser's localStorage and sent directly from your browser to the provider — never to KLI Prompts. We have no backend that can see it.

How this works (honestly)

Your key lives in localStorage on this device only.
The HTTP request to the LLM goes from your browser straight to api.anthropic.com / api.openai.com / openrouter.ai.
KLI Prompts has no server endpoint that receives, logs, or proxies your key.
Clear it any time — there's a button below.

Final prompt (sent to anthropic)

You are writing a payment-reminder email to an Indian client whose invoice is overdue. Tone: warm, firm, never aggressive. The goal is payment, not a fight.

## Inputs
- Client / company being billed: {{client_name}}
- Recipient name (AP / finance contact): {{recipient_name}}
- Invoice number: {{invoice_number}}
- Invoice date: {{invoice_date}}
- Due date: {{due_date}}
- Days overdue: {{days_overdue}}
- Amount due (INR): ₹{{amount_inr}}
- Late fee / interest clause per agreement (e.g. 1.5% per month, or "none"): {{late_fee_clause}}
- Payment methods accepted (NEFT/UPI/cheque etc.): {{payment_methods}}
- Sender name + company: {{sender_name}}, {{sender_company}}

## Output (email format)
- Subject line: include invoice number and "gentle reminder" or "reminder" — never "URGENT" or all caps.
- Greeting: "Dear {{recipient_name}}," (or "Hi {{recipient_name}}," if days_overdue < 15).
- Body in 3 short paragraphs:
  1. Reference the invoice (number, date, amount in ₹). State it's overdue by {{days_overdue}} days. No accusation — assume good faith.
  2. Restate payment methods. If late_fee_clause is not "none", mention the clause exactly as agreed — once, neutrally — and that it will start applying from a specific date.
  3. Offer to resolve any blockers (missing PO, GST detail, duplicate). Give a contact (email/phone placeholder).
- Sign-off: "Warm regards, {{sender_name}} — {{sender_company}}".

Do NOT include emojis. Do NOT threaten legal action. Do NOT use the phrase "as per our records". Keep total length under 180 words.
