Direct answer
A commercial demand letter should identify the correct parties, transaction, principal amount, currency, due date, performance, prior contact, known dispute, requested response, deadline and contact route. It should not invent statutes, lawyer signatures, authority, threats or facts, and it is not a substitute for jurisdiction-specific advice.
Preparation sequence
- Set the immediate objective: payment, acknowledgement, evidence, a plan or a response to a dispute.
- Verify every party, amount, date, performance statement and supporting document.
- Address known disputes accurately and separate uncertain amounts or charges.
- Check the contract's notice terms and the current pre-action expectations for the relevant forum.
- Choose a realistic response date and pre-authorize who can negotiate, settle or escalate.
Decisions to record
What is the letter asking the recipient to do?
State the exact payment, supporting information or substantive response requested, the currency, a real date and a monitored contact route.
Can every factual statement be proved?
Link the parties, transaction, performance, invoice, due date, balance and prior contact to the evidence pack; remove unsupported adjectives and accusations.
Has the known dispute been addressed?
Describe it accurately, identify what remains unresolved and invite the specific evidence or response needed rather than pretending the issue does not exist.
What happens after the deadline?
Record who can accept payment, negotiate a plan, approve a settlement, seek qualified advice or stop uneconomic work; do not threaten a step that has not been assessed.
Evidence to organize
- Contract, order and notice terms
- Invoice-level account statement
- Performance and acceptance evidence
- Reminder, dispute and payment chronology
- Sending method, delivery record and internal authority
Example decision record
Objective: obtain USD 37,000 or a documented delivery dispute response. The draft identifies the contract and two invoices, credits the USD 5,000 already issued, describes the disputed milestone neutrally, requests payment or supporting records by a stated date, and gives one monitored contact. It does not claim to be a lawyer's letter or promise proceedings.
