Demand Letter
A demand letter is a formal written request from a supplier to a buyer to pay a stated overdue amount by a clear deadline.
Also called: payment demand letter, letter of demand, final reminder letter
What it means
A demand letter is the step between friendly reminders and lawyers. It is written by the supplier itself, on letterhead, and sent by email, WhatsApp, courier or registered post. A good demand letter lists:
- The invoices, dates and amounts unpaid.
- Any payments already received.
- The total now due, and interest if you are claiming it.
- A clear deadline to pay.
- How to pay, for example a UPI ID or bank details.
- What you may do next if the amount is not paid.
Between businesses, a demand letter is good practice, not a legal requirement before filing a claim.
Why it matters for getting paid
A written demand shows you are serious while keeping the tone respectful. It often prompts payment from buyers who ignored WhatsApp messages, and it creates a dated record that is useful if you later send a legal notice, file a civil suit, or, as a Udyam-registered micro or small manufacturer or service provider, file under the MSMED Act on the MSME ODR portal. If the buyer replies admitting the debt in writing, keep that reply: a written acknowledgment before the 3-year limit expires starts a fresh limitation period.
Use it when an invoice moves into the older buckets of your overdue ageing, or after a buyer has broken a promise to pay more than once.
Keep it factual. Avoid threats you do not intend to carry out, and never contact the buyer's family or customers. Threatening injury to a person, reputation or property to force payment can amount to criminal intimidation under Section 351 of the Bharatiya Nyaya Sanhita, 2023.
Example: "Invoices totalling ₹3,45,000 are overdue. Please pay by 30 November."
