Late Payment Demand Letter
A firm, professional letter for an invoice that has gone unpaid: what is owed, when it was due, a new deadline, and what happens next — plus a record of the reminders you already sent, which is exactly what you will need if this ends up in front of anyone.

Frequently asked
Is this a legal notice?
No. It is a business letter and not a statutory or pre-action notice. Debt-collection rules vary by state and some require specific wording before you escalate — check what applies to you.
Should I keep working while an invoice is overdue?
Your call, but record the decision. The letter includes a 'work paused' line because doing it silently causes disputes.
