Unpaid Invoice Demand Letter
Draft unpaid Invoice Demand Letter with an escalation ladder and an evidence checklist.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Write a demand for payment of an overdue invoice from a customer. Facts I will give: customer [CUSTOMER_NAME], invoices [INVOICE_LIST], amounts [AMOUNTS], due dates [DUE_DATES], work delivered [WORK_DELIVERED], payment terms [PAYMENT_TERMS], previous reminders [PREVIOUS_REMINDERS]. Please have the letter list the invoices in a short table, restate the agreed terms, mention earlier reminders with dates, state the total, and give the pay-by date and method. Interest or fees should be added only if my contract provides and I enter the figures. What to collect first: the contract or quote, each invoice with date and amount, proof of delivery or acceptance, payment terms, and a list of reminders sent with dates. What I can realistically request: payment in full by a stated date by a named method, interest or fees only where the contract provides for them, and written acknowledgement. Expect a response like: "We never received the invoice." Answer by attaching copies and the sent records, and restate the due date. Give me three versions of the letter for the unpaid invoice demand letter, one firm, one neutral, and one final notice, each between 180 and 280 words with the same facts throughout. Deliver the letter itself together with a cover note of roughly 60 words, plus an if-ignored ladder (payment chase call, then final notice by tracked mail, then small-claims or debt-recovery information for my area), then the documents to collect (contract, invoices, proof of delivery, reminders), plus one records tip. Send the letter by a tracked route with a return receipt, and store the tracking page once it shows delivered. Draft the letter as me, a private individual, not as any legal professional, and use no made-up titles or licence numbers. Pause for any blank fact before you write and list the claims that rest on memory alone. Leave all legal citations and cut-off dates to me; rely on [JURISDICTION] and [RELEVANT_LAW_OR_POLICY_IF_KNOWN], and remind me to check the exact law with a qualified professional or a local consumer agency. I need wording to review, not a legal opinion, so avoid telling me what would win. Stay calm, plain and courteous, with nothing hostile or exaggerated, and put the date from [DEADLINE] on any request.
