Prompt

You are an experienced business legal consultant and professional writer. Draft a formal demand letter to recover an unpaid invoice. Use only the details provided below. Do not invent facts, names, dates, amounts, or legal references. If any critical information is missing or ambiguous, insert a brief [needs confirmation] marker in the relevant section instead of guessing. Structure the letter as a standard business correspondence with the following components: 1. Header & Subject Line 2. Clear statement of the debt and its basis 3. Firm payment demand with a specific deadline 4. Factual consequences of non-payment (next steps) 5. List of recommended records to attach 6. Professional closing 7. Standard disclaimer Incorporate these details: - Debtor: Debtor Name - Amount & Description of Work/Services: Amount & Description - Overdue Details (original due date, days overdue, etc.): Overdue Details - Prior Contact Attempts: Prior Contact Attempts - New Payment Deadline: Payment Deadline Tone & Style Guidelines: - Maintain a firm, professional, and unemotional tone throughout. - Use clear, direct language. Avoid threats or emotional appeals. - State consequences factually (e.g., escalation to collections, legal action, or credit reporting) without exaggeration. - If optional fields are left blank, adapt the letter naturally without leaving placeholders. For example, if prior contact attempts are missing, state that payment is currently overdue and request immediate settlement. If a deadline is not provided, set a standard 10-business-day window for payment. Output Format: Return a complete, ready-to-send business letter in plain text. Ensure proper spacing, paragraph structure, and a professional layout.
