A payment demand letter (or demand for payment) is a formal written request for money owed — an unpaid invoice, personal loan, security deposit refund, or damages. It states the amount owed, the basis, a deadline, and consequences if not paid (collections, small claims or lawsuit).
A well-drafted demand letter is often the first thing a small-claims judge asks for. Send it via certified mail with return receipt (and email) so you have proof the other side received it. Keep a copy.
What to include#
- Your details and theirs. Your name/company, address and contact; recipient name/company and address; date of letter.
- Amount owed. Total amount due, including any interest, late fees or costs, with a breakdown.
- Basis of the debt. What the money is for (unpaid invoice #X dated Y, personal loan on date Z, damages from incident on date) with attached copies of invoices/contracts.
- Deadline and payment method. Deadline for payment (typically 14-30 days) and how/where to pay.
- Consequences. Statement of next steps if not paid by the deadline (small claims court, collections attorney, eviction) — without threatening criminal action.
How to fill it in#
Step 1: Gather documentation
Pull the invoice, contract, emails and any proof of delivery/payment attempts to attach.
Step 2: State the facts calmly
Do not editorialise or threaten — state amount owed, what it is for, and deadline plainly.
Step 3: Calculate the total correctly
Include interest/late fees only if allowed by contract or law; show a breakdown.
Step 4: Set a clear deadline
Give enough time for response (14-30 days is typical) and specify the payment method/address.
Step 5: Deliver with proof
Send by certified mail (return receipt) and email; keep a signed copy and tracking receipt.

Questions
Is a demand letter required before suing?
Often not legally required, but small claims courts and attorneys strongly recommend (and in some jurisdictions expect) a written demand before filing.
Should I send by email or mail?
Both — email for speed, certified mail for proof of receipt. Certified mail return receipt is the strongest evidence.
Can I add interest?
Only if the contract or a state statute allows it; in many states you can add post-judgment interest, but pre-judgment interest must be contractual.
What if they ignore it?
You can proceed to small claims court, collections, or hire an attorney based on the amount and merits.
Do I need a lawyer?
You can write one yourself; a lawyer adds weight for larger amounts or if you expect litigation.
