Unpaid invoices are a business problem, not a personal one. A structured escalation — friendly reminder, firm reminder, formal demand — usually resolves it without collections agencies or court.
The escalation ladder
- Day 1 after due date: friendly reminder email.
- Day 15: firm follow-up email referencing the contract.
- Day 30: formal demand letter, delivered with tracking.
Why the formal letter matters
Emails are easy to ignore. A tracked, signed-for letter is not. It also creates the record most courts want to see before a claim proceeds.
What to include
- The invoice number, date, and amount
- A brief description of the services rendered
- The specific payment deadline (10–14 days)
- Notice that interest and reasonable collection costs may be added
- Your contact information for prompt resolution
Most clients pay after the third step. Those who don't have effectively selected themselves for small-claims court — and now you have the paper trail.
