Payment Demand Letter for Transport and Charter Operators

You should send a formal demand letter when an invoice is 30 to 45 days past due and your standard email reminders have been ignored. Sending it too early can strain client relationships, while waiting past 60 days significantly reduces your chances of recovery. This timeline establishes a clear boundary while giving your client a final opportunity to settle amicably.

You can only charge interest or late fees if they were explicitly detailed in your original charter contract or terms of service signed by the client. If your contract did not include a late payment clause, you are limited to demanding the original invoice amount. Always check local state laws, as there are statutory limits on the maximum interest rates you can charge on overdue commercial accounts.

You should send the demand letter through both physical certified mail with a return receipt requested and digital email with read-tracking enabled. Certified mail provides legal proof of delivery, which is essential if you need to escalate the dispute to small claims court. The email copy ensures the client receives the notice instantly and cannot claim they missed it in the mail.

If the deadline passes without payment or a realistic payment plan, you must follow through with the consequences outlined in your letter. You can submit the outstanding account to a commercial debt collection agency or file a claim in small claims court if the balance falls within your local jurisdiction's limits. Promptly taking these next steps shows the client that your terms are non-negotiable.
