How to Politely Chase a Late Invoice (With Email Templates)

The invoice was due last week. The client hasn't paid. They're probably not ignoring you on purpose, but you also have bills to pay. How do you chase them without sounding desperate, rude, or unprofessional?

This guide walks through exactly how to chase a late invoice at every stage, with email templates you can copy and paste.

The golden rules of chasing payment

Before we get to the templates, three principles to remember:

1. Assume good intent first. Most late payments are oversights, not malice.
2. Stay professional, always. Even if you're frustrated, never let it show in writing.
3. Be persistent. Polite, repeated reminders work. Disappearing for 3 months and then demanding payment doesn't.

Now let's get into it.

Stage 1: Day after due date — friendly reminder

Send this the day after the invoice was due. It's gentle, assumes good intent, and gives them an easy out.

Subject: Friendly reminder: Invoice INV-0042

Hi [Client Name],

Just a quick note that invoice INV-0042 (for $1,250) was due yesterday and I haven't seen the payment come through yet.

It's likely just slipped through the cracks. Could you let me know when it'll be processed? Bank details are on the original invoice but I'm happy to resend if helpful.

Thanks, [Your Name]

This usually works. Most clients will apologise, pay within a day or two, and the relationship stays intact.

Stage 2: 7 days overdue — firmer follow-up

If you haven't heard back after a week, send this. It's still polite but more direct.

Subject: Invoice INV-0042 — now 7 days overdue

Hi [Client Name],

Following up on invoice INV-0042 which is now 7 days overdue.

Could you confirm when payment will be made? If there's an issue with the invoice or you need any additional information, please let me know so we can resolve it quickly.

Looking forward to your reply.

Best, [Your Name]

Notice the question at the end. Asking "when will it be made?" forces a response. Vague phrases like "please let me know" are easier to ignore.

Stage 3: 14 days overdue — escalation

If you've sent two reminders and still no response, it's time to escalate. Pick up the phone if you have their number. Email is too easy to ignore. If you can't call, send this.

Subject: Action required: Invoice INV-0042 (14 days overdue)

Hi [Client Name],

I've followed up twice on invoice INV-0042 ($1,250), which is now 14 days overdue, and haven't received a response.

Please reply by [date 3 days from now] with either:

1. Confirmation of when payment will be made, or
2. Details of any issue preventing payment

I'd really like to resolve this quickly without further action being necessary.

Thanks, [Your Name]

The deadline and numbered list make this feel official without being aggressive. The phrase "further action" hints at consequences without spelling them out yet.

Stage 4: 30+ days overdue — final demand

If you're a month past due with no communication, you need to be clear that this is serious.

Subject: Final notice: Invoice INV-0042 (30 days overdue)

Hi [Client Name],

Invoice INV-0042 for $1,250 is now 30 days overdue. Despite multiple reminders, I haven't received payment or a response.

This is my final reminder before I:

• Add a late payment fee of [X%] as per our agreement
• Pause any further work on your account
• Refer the matter to a debt collection agency

Please make payment in full by [date 7 days from now] to avoid this.

If there is a genuine reason you can't pay right now, please contact me so we can discuss a payment plan. I'd much rather work this out directly.

Regards, [Your Name]

This is firm but still leaves a door open for resolution. Most clients will respond to this. The ones who don't, you probably need to consider legal action.

Late payment fees: should you charge them?

If your original quote or invoice stated a late fee policy, yes, apply it. Common terms are:

• A flat fee (e.g. $25) per reminder
• An interest rate (e.g. 2% per month) on the overdue amount

Even if you don't actually collect the fee, having it in your terms gives you leverage. Most clients will rush to pay just to avoid the fee.

Important: You can only charge late fees if they were agreed upfront. If your original quote or invoice didn't mention them, you can't add them now.

Tips for getting paid faster

The best way to chase invoices is to not have to chase them in the first place. A few things that help:

• Send the invoice immediately after the work is done. Delays on your side give the client an excuse to delay on theirs.
• Make payment instructions crystal clear. Bank details, reference number, due date, all in one place.
• Use software that timestamps when the invoice was viewed. This kills the "I never got it" excuse.
• Take a deposit upfront. For larger jobs, 30-50% before work starts is reasonable.
• Set clear payment terms in your quote. "Payment due within 14 days of invoice date" should appear on every quote you send.

If you're consistently chasing the same clients, it might be time to part ways. Read 5 small business mistakes when sending quotes for more on this.

What if they still don't pay?

After your final demand, your options are:

1. Debt collection agency. They typically take 20-30% of the recovered amount but handle everything for you.
2. Small claims court. Cheap and you don't need a lawyer for amounts under most jurisdictions' thresholds.
3. Write it off. If the amount is small or the client is bankrupt, sometimes it's not worth the time.

For amounts under a few hundred dollars, the cost of pursuing payment often exceeds the debt. Cut your losses, learn the lesson, and don't work with that client again.
