Free Templates Where Every Format Actually Computes
Past-due letter templates
Chasing money is a sequence, not an outburst. This pack is the four-step ladder used by professional collections: friendly reminder, second notice, firm notice, final demand - each one calibrated so the next rung stays credible.
Why a ladder beats ad-hoc chasing
Senders who escalate on a fixed schedule collect more and burn fewer relationships than ad-hoc chasers, because the tone escalates instead of the emotion. The client always knows where they are in the sequence and what happens next - which is precisely what makes paying now the easy choice.
What each rung does
Letter 1 (3-7 days late) assumes good faith and removes friction. Letter 2 (30 days) introduces the late fee and offers a payment plan. Letter 3 (60 days) pauses work and names the escalation path with a deadline. Letter 4 (90+) is the final demand: pay by the date or the account goes to collections or small claims. Never skip rungs; the sequence is the credibility.
Legal care in the final letters
The firm letters state consequences you are actually prepared to take, give a specific deadline, invite written dispute, and reserve your rights. Do not threaten actions you will not take and do not add charges your invoice terms never established - both weaken any later proceeding.
The 4-step ladder
| Letter | When to send | The move |
|---|---|---|
| 1. Friendly reminder | 3-7 days past due | Assume oversight, remove friction |
| 2. Second notice | ~30 days | Late fee starts, payment plan offered |
| 3. Firm notice | ~60 days | Work paused, escalation named, deadline set |
| 4. Final demand | 90+ days | Pay by date or collections / small claims |

Past-due letter FAQ
Email or physical letter?+
Email for letters 1 and 2. For letters 3 and 4, send both email and tracked physical mail - the envelope itself signals seriousness, and delivery proof matters if you end up in small claims.
Can I charge late fees?+
Only if your invoice or contract established them before the work, and within your state’s limits. A late fee that first appears in a dunning letter will not survive a dispute.
When do I actually go to collections?+
When the final-demand deadline passes. Follow through matters: a final demand you do not act on teaches the client that none of your letters mean anything.
