An unpaid invoice doesn’t expire the moment it goes overdue — but your practical window to collect narrows fast. Understanding the legal deadlines for pursuing unpaid invoices and knowing when to escalate your response are two of the most important things a freelancer or small business can learn. Here’s the full picture.
Most freelancers and contractors don’t think about the legal side of invoicing until they’re staring at an invoice that’s 60 days past due and wondering what to do. The good news: you have more options than you think. The bad news: the longer you wait, the fewer of them work.
The statute of limitations on unpaid invoices
The statute of limitations (SOL) sets a deadline for how long you can legally sue to collect a debt. After that deadline, courts will typically dismiss your case even if the debt is valid.
For invoices and service contracts, the relevant statute is usually one of these:
- Written contracts: Most states allow 4–6 years. Some allow up to 10 years.
- Oral agreements: Shorter — typically 2–4 years.
- Open accounts (ongoing business relationships without a single contract): Varies, usually 3–6 years.
Statute of limitations by state (selected):
| State | Written Contract SOL |
|---|---|
| California | 4 years |
| Texas | 4 years |
| New York | 6 years |
| Florida | 5 years |
| Illinois | 5 years |
| Ohio | 6 years |
| Pennsylvania | 4 years |
| Washington | 6 years |
| Georgia | 6 years |
| Massachusetts | 6 years |
The clock typically starts on the invoice due date. If your invoice was due January 1, 2026, and your state has a 4-year SOL, you have until approximately January 1, 2030 to file a lawsuit.
Important exception: If the client acknowledges the debt in writing (even an email saying “I know I owe you, I’ll pay next month”), in many states this resets the clock to the date of that acknowledgment.
The statute of limitations is a last-resort consideration. In practice, an invoice that goes unpaid for 3+ years is almost never collected at full value. Knowing the legal deadline is useful, but your real goal is to resolve the invoice within 90 days — before it becomes a legal problem.
The practical overdue timeline: what to do at each stage
Legal options aside, the practical window for collecting most unpaid invoices is much shorter than the statute of limitations. Here’s how recovery rates shift over time and what to do at each stage.
Day 1 overdue: first reminder
Send a brief, friendly reminder the same day payment becomes due. Many late payments are simply forgotten, not intentional. A quick email with the invoice attached recovers a significant number of these immediately.
Expected recovery rate: Very high (70–80% of late payments are resolved at this stage).
What to do: Email reminder, attach invoice, confirm their payment method is correct.
Day 7 overdue: second notice
If no response or payment after a week, send a second notice. Slightly firmer in tone, but still professional. Ask directly: “Is there an issue with this invoice I should know about?”
Expected recovery rate: Good (another 15–20% resolved here).
What to do: Second email, call if you have the client’s phone number, confirm they received the invoice.
Day 14–30 overdue: formal notice
Now you’re moving from friendly follow-up to formal communication. Your email should:
- Reference all previous contact attempts
- State the original due date clearly
- Include accumulated late fees if your contract allows them
- Set a specific deadline for payment (e.g., “Payment is required by [date]”)
Expected recovery rate: Another 10–15% resolved here. By day 30, you’ve recovered most of what you’re going to recover through email alone.
What to do: Formal email, consider a phone call or video call, send a physical letter if the amount is significant.
Day 60 overdue: escalation decision
At 60 days, you need to decide: escalate legally or write it off. The options:
- Small claims court: For amounts under your state’s limit ($5,000–$25,000 depending on state). Filing is inexpensive ($30–$100) and you don’t need a lawyer.
- Collections agency: They pursue the debt for a percentage of recovery (25–50%). No upfront cost to you.
- Demand letter from attorney: A formal letter from a lawyer gets results in some situations without going to court. Many attorneys offer this for a flat fee of $100–$300.
- Write it off and learn: For small invoices where the cost of pursuit exceeds potential recovery.
Expected recovery rate at 60 days: Significantly reduced — perhaps 40–50% of remaining unpaid invoices.
Day 90–120 overdue: final options
At this point, you’ve exhausted routine follow-up. Your options are legal action or collections referral.
Small claims court process:
- File your claim at the local courthouse (or online in many states)
- Pay the filing fee ($30–$100)
- Serve the defendant (often done by the court or a process server)
- Attend the hearing — bring your contract, invoices, and any communication history
- If you win, you receive a judgment — the court doesn’t collect for you, but you can garnish wages or bank accounts in many states
Collections agency:
- Agencies typically take 25–40% of collected amounts
- Debt buyers (who purchase the debt outright) may pay 10–20 cents on the dollar
- Use only if you’ve given up on the relationship — collections permanently damages the client relationship
Expected recovery rate at 90+ days: 20–30% of invoices unpaid at this stage are ever fully recovered.
State-by-state small claims court limits
| State | Small Claims Limit |
|---|---|
| California | $12,500 (individuals) |
| Texas | $20,000 |
| New York | $10,000 |
| Florida | $8,000 |
| Illinois | $10,000 |
| Ohio | $6,000 |
| Pennsylvania | $12,000 |
| Georgia | $15,000 |
Check your state’s current limit before filing — these change periodically.
How to prevent overdue invoices
The best strategy is avoiding the 60-day problem entirely.
Require a deposit: A 25–50% upfront deposit is standard in most freelance fields. It eliminates clients who weren’t serious and dramatically reduces non-payment risk on the back end.
Short payment terms: Net 15 instead of Net 30 gets you paid twice as fast. Many clients will pay within net-30 regardless of what you specify — but the shorter the stated terms, the faster they act.
Make payment easy: Invoices with a one-click payment link get paid 2–3x faster than invoices that require the client to initiate a bank transfer or write a check. Friction is your enemy.
Follow up early: Don’t wait until day 14 to notice an invoice is overdue. Use invoicing software that shows you invoice status and reminds you (or the client automatically) on day 1.
Get it in writing: Every project should have a written contract or at minimum a written scope-and-rate agreement before work begins. Without this, legal escalation is significantly harder.
Include late fees: A 1.5% monthly late fee, stated in your contract and on the invoice, creates a financial incentive to pay on time. You may never enforce it — the threat alone helps.
When to write off an invoice
Sometimes the cost of pursuing an overdue invoice exceeds the value of recovering it. Write-off factors:
- The invoice amount is small relative to your time investment
- The client has clearly no ability to pay (business closed, personal hardship)
- You’ve already spent 3+ hours on follow-up
- The relationship was already over and you won’t seek future work from them
Tax note: In the US, unpaid invoices can sometimes be deducted as bad debt. Consult an accountant — the rules differ for cash-basis vs. accrual-basis taxpayers.

Don’t wait until an invoice is 90 days overdue to act. Build a consistent follow-up schedule, require deposits on new projects, and make payment as frictionless as possible. The legal options exist — but you’ll almost never need them if you address late payments in the first two weeks.
