Client Won't Pay Invoice: What to Do (Step-by-Step)
You sent the invoice. You did the work. And now your client has gone silent. This guide walks you through every step — from a polite nudge to a formal demand — with exact email scripts you can send today.
⚡ Quick diagnosis: how overdue is your invoice?
- 1–7 days late: Probably not ignoring you — scroll down to Step 1.
- 8–21 days late: Time to get firm — jump to Step 2.
- 22–45 days late: Formal escalation — Step 3.
- 45+ days late: Nuclear options — Step 4.
Step 1: The polite reminder (1–7 days late)
Before assuming the worst, send one friendly reminder. Invoices genuinely get lost in inboxes, marked as read and forgotten, or buried under accounts payable queues. Keep this email short and assume good faith.
Email Script — Day 7 Gentle Reminder
Subject: Invoice #[XXX] — Quick Check-in
Hi [Name],
Hope you're doing well! I wanted to drop a quick note about Invoice #[XXX] for [project/amount], which was due on [date].
Could you let me know if everything looks good on your end, or if there's anything I can help clarify?
Thanks so much,
[Your name]
What to expect:Most clients pay after this email. You'll hear something like "Oh sorry, I totally missed it!" and get paid within 48 hours.
Step 2: The firm follow-up (8–21 days late)
Still nothing? Time to be direct. The tone shifts from "just checking" to "this needs to be resolved." You're not being rude — you're being professional about your right to be paid.
Email Script — Day 14 Firm Reminder
Subject: Invoice #[XXX] — 2 Weeks Overdue
Hi [Name],
I'm following up on Invoice #[XXX] for [amount], which is now 2 weeks past the due date of [date].
I'd really appreciate payment by [specific date, e.g., this Friday]. If there's a problem with the invoice or the work, please let me know so we can resolve it.
If payment has already been sent, please disregard this message and send me the reference number.
Thank you,
[Your name]
Email Script — Day 21 Escalation Warning
Subject: Invoice #[XXX] — Payment Required by [Specific Date]
Hi [Name],
Invoice #[XXX] for [amount] is now 3 weeks overdue. I've sent two previous reminders without response.
I need payment by [date — give 5 business days]. If I don't receive payment or hear from you by then, I'll need to escalate this matter.
I'd much prefer to resolve this directly with you — please reach out if there are any issues.
Regards,
[Your name]
Step 3: Formal demand + late fees (22–45 days late)
If you included late fees in your contract or invoice terms, now is when you invoke them. Add the accrued late fee to the invoice total. This does two things: it compensates you for the delay AND it creates urgency ("it's getting more expensive every day").
Email Script — Formal Demand with Late Fee
Subject: Formal Payment Demand — Invoice #[XXX] + Late Fee
Hi [Name],
This is a formal demand for payment of Invoice #[XXX], originally for [original amount], now totalling [amount + late fee] including the late payment fee specified in our contract/invoice terms ([X]% per month).
This invoice is [N] days overdue. I require full payment within 7 calendar days of this email.
If payment is not received by [specific date], I will have no choice but to pursue this through [small claims court / debt collection / legal action] and report this to credit reference agencies where applicable.
Please treat this as urgent.
[Your full name]
[Your business name + registration number if applicable]
Important: CC this email to another address (like a second inbox you own) to create a timestamped paper trail. This matters if you end up in small claims court.
Step 4: Nuclear options (45+ days, still no payment)
At this point you need to decide: is the amount worth pursuing? Here are your options, roughly in order of effort vs. recovery chance:
🏛️ Small Claims Court
In most countries this costs $30–$150 to file and requires minimal legal knowledge. In the US, limits are $5K–$25K depending on state. In the UK it's called "Money Claim Online" (MCOL). Win rate for clear-cut unpaid invoices is high — most defendants settle before the hearing.
📋 Debt Collection Agency
They typically take 25–40% as a fee, but collect on your behalf. Best for invoices over $1,000 where you don't want the hassle of court. The mere letter from a collections agency causes many clients to pay immediately.
📣 Public reviews
Leave an honest review on Google, Trustpilot, or Clutch.co. Describe the situation factually without emotional language. Many businesses respond quickly to protect their reputation. Do this only after you've exhausted direct contact.
⚖️ Solicitor / Attorney letter
A letter from a lawyer often costs £50–$200 and causes immediate payment. Many legal firms offer fixed-fee debt recovery services for small amounts.
How to prevent this from happening again
The best payment chase is the one you don't have to send. Here's what separates freelancers who rarely have payment issues from those who constantly deal with this:
- ✓50% upfront deposit.Non-negotiable for new clients. Eliminates most payment risk because you've already been partially paid.
- ✓Net 14 instead of Net 30. The longer the payment window, the more likely it gets deprioritised. Two weeks is still professional and reasonable.
- ✓Automatic reminders. Manual follow-up is awkward and inconsistent. Set up a system that sends reminders automatically at day 3, 7, 14, and 30 — before you feel the emotional pressure of having to chase manually.
- ✓Late fee clause in your contract.Even if you never enforce it, it signals you're serious about getting paid on time.
- ✓Stop work clause. State in your contract that work pauses on invoices 30+ days overdue. This creates real business pressure.

Frequently asked questions
Can I charge interest on a late invoice?
Yes, in most countries you can charge statutory interest on late commercial payments. In the UK it's 8% + Bank of England base rate under the Late Payment of Commercial Debts Act. In the US it varies by state but you can specify a rate in your contract. Include it in your terms upfront so clients are aware before they sign.
What if my client disputes the invoice?
First, take the dispute seriously even if you think it's bad faith. Ask them to put the specific objection in writing. Legitimate disputes should reference specific deliverables or project scope. If the dispute is vague ("I'm not happy with the work"), ask for concrete details. A paper trail of you engaging in good faith protects you if this goes to court.
How many reminders is too many?
Three to five reminders over 30–45 days is standard before escalating to legal options. After that, more emails just waste your time and may actually reduce pressure by normalising the non-payment. Escalate or move on.
Should I stop working for this client while chasing payment?
Yes — once an invoice is 30+ days overdue, pause any ongoing work until payment is received. Continuing to deliver while a client hasn't paid tells them the relationship will continue regardless of payment behaviour. Most contracts allow you to suspend services for non-payment. Check yours.
