It is 9pm. You have an invoice that is 38 days late, a client who answers texts about new work but not about old bills, and a folder of emails that go in circles. You need a plan with dates on it, not another vague "follow up soon." A collections escalation timeline is that plan: a written sequence that tells you exactly what to send, when to send it, and when to stop chasing.
Why a Timeline Beats Instinct
Without a written timeline, you wait too long, then escalate too hard, then go quiet again. Clients read that pattern as "this person will eventually give up." A fixed schedule does the opposite: every step happens on a date you set in advance, regardless of how you feel that week.
A good timeline also protects you in court. Judges in small claims cases want to see a clear paper trail of escalating contact. Random follow-ups over six months look like confusion. Five dated steps over 60 days look like a contractor who knew what they were doing.
The Standard 60-Day Collections Timeline
This is the sequence most independent contractors should run by default. Adjust the day counts if your contract specifies different payment terms, but keep the structure.
- Day 0 (due date): Send the invoice as a PDF with a clear due date and payment instructions.
- Day 3 past due: Short, friendly email reminder. Re-attach the invoice. Assume oversight.
- Day 10 past due: Second email plus a text. Mention the late fee that kicks in at day 30 if your contract allows one.
- Day 15 past due: Phone call from a number they recognize. Follow up the call with a written summary by email the same day.
- Day 30 past due: Polite written demand letter (Option 1). Sent by email and certified mail. 10-day deadline.
- Day 45 past due: Firm demand letter (Option 2). Certified mail. 7-day deadline. Reference the unpaid late fees.
- Day 55 past due: Final demand letter (Option 3). Certified mail. References small claims court in your state with the filing limit.
- Day 65 past due: File in small claims court or write the debt off. Do not send a fourth letter.
For larger invoices or commercial clients with longer net-60 terms, shift each step out proportionally. The structure stays the same.
What Each Step Actually Says
The early steps are short. Two sentences and the invoice attached. Friction kills early payment, so make it stupid-easy to pay.
The three letters at the end are where most contractors lose the case before they file. They write one angry message and call it done. Three escalating versions work better because each one gives the client a clean off-ramp before the next level of consequence. Our guide on writing a dispute letter that gets you paid walks through the language for each version.
Keep every message in writing. If you take a phone call, send a summary email within an hour: "Following up on our call at 2:15pm today: you said you would pay invoice INV-118 by Friday, June 12. Confirming that here for both our records."
Documentation You Build Along the Way
Every step in the timeline doubles as evidence. By day 65 you should have a folder with:
- The signed contract or accepted estimate
- The original invoice and any change orders
- Timestamped photos of the completed work
- Every email, text, and call log with dates
- Copies of all three demand letters and the certified mail green cards
If the client is the type to go silent after an invoice, this folder is what forces them back to the table once they are actually served. Without it, a judge has your word against theirs.
When to Compress or Skip Steps
The 60-day timeline assumes a client who is slow or avoiding you. Compress it in two situations.
The client has already disputed the invoice. Skip the friendly reminders. Jump to a written response to the dispute, then go straight to Option 2 within 14 days. Dragging out reminders signals weakness when the client has already drawn a line.
The client is going out of business or selling assets. Compress the entire sequence to 21 days. File in small claims as soon as the final letter deadline passes. Waiting another month often means waiting for an empty bank account.
When to Stop Chasing and File
The hardest part of any collections timeline is the end. After three certified letters and no payment, sending a fourth letter does nothing. The client has read your escalation pattern and decided to call your bluff.
At day 65, you have two honest options: file in small claims court, or write the debt off and move on. Both are legitimate. The wrong choice is to keep sending letters into the void for another six months.
Writing three escalating letters from scratch (calibrated to your state's small claims limit, with the right tone at each stage) is what most contractors put off until the debt is too old to collect. PaperHammer drafts all three letters in about five minutes from the details of your job and your client, so the timeline above actually gets executed instead of sitting in your head.
