# Demand Letter — Unpaid SaaS Subscription Invoices (SG-SG, Business to Business) > **Sample document — not legal advice.** This document was drafted by the LawCrew AI agent team and is published at `lawcrew.ai/samples` as a showcase of how our pipeline approaches a common Singapore Demand Letter scenario. This run completed automated drafting, self-critique, adversarial review and deterministic gates, then routed to lawyer review (Auto-revision exhausted after 5 attempts. Remaining: 3. Summary of Claim: Stating that the services were 'accepted without complaint' is an overstatement that characterizes the Respondent's silence or actions as a formal legal acceptance, which may be contested.; 3. Summary of Claim: Asserting a due date without referencing the underlying factual basis (e.g., the specific contractual payment terms) constitutes an unsupported legal conclusion.; 8. Payment Instructions: The draft currently relies on bracketed placeholders, meaning actionable payment instructions are missing. These must be populated with actual banking details (and ideally a SWIFT/BIC code for completeness) before sending.; Section 5: Amount Demanded: The demand claims 'interest as may be agreed under the contract', yet the factual chronology completely omits any mention of an interest clause, rate, or late payment terms within the 3 January 2026 order form. As the respondent's counsel, we note this claim for contractual interest is a fishing expedition that lacks a supporting factual basis in the letter.). **It is not legal advice and is not tailored to any specific transaction.** > > LawCrew is a legal-technology service, not a law firm.
