Chasing an overdue invoice does not have to mean an awkward phone call or a threatening email. These copy-paste invoice chasing email templates give you the right words for every stage, from a friendly reminder before the due date to a firm final notice, so you get paid without damaging the client relationship. Alongside the reminders, a statement of account template summarising every outstanding invoice in one document often moves payment faster.
Your job as the searcher is simple: find wording you can copy, send at the right time, and trust to work. This guide answers that job in the first section, then gives you the full sequence, a send schedule, a reply guide for whatever the client says back, and the UK late-payment rules that back up your final notice.
Every template below starts with a subject line and uses square brackets for the details you fill in. Replace them, check the invoice number and amount twice, and send. One email should ask for one thing only: payment by a named date, or a confirmed payment date.
What is an invoice chasing email?
An invoice chasing email is a message that reminds a client an invoice is due or overdue. It states the invoice number, amount and due date, and asks for one clear action, such as paying by a named date. It is not a complaint or a threat. Sent in sequence, these emails turn a silent delay into a clear record.
That record matters. If a client later claims they never saw the invoice, or a dispute reaches a formal stage, your sent emails show exactly when you reminded them and what you asked for. Keep every chase in the same email thread as the original invoice, so the whole history sits in one place.
A chasing email is different from the email that sends the invoice in the first place. The first email delivers the work and the bill. A chase assumes the client already has it and asks what is happening with payment. If you are still at the sending stage, start with our guide on how to send an invoice by email, then return here for the follow-ups.
When should you send each chasing email?
Send a friendly reminder three days before the due date, a short note on the due date, a firmer check-in three days after it, and a final notice at fourteen days overdue. That rhythm gives the client four chances to pay or reply before you escalate, and it creates a paper trail that shows you acted reasonably at every stage.
| When to send | Tone | What it must do |
|---|---|---|
| 3 days before the due date | Friendly | Put the invoice back on the client’s radar and catch errors early |
| On the due date | Neutral | Confirm the payment is due today and give the payment link again |
| 3 days overdue | Firm but polite | Ask for a payment date and invite the client to raise any query |
| 14 days overdue | Formal | Set a final deadline and state the next step if payment does not arrive |
Do not send a chase every day. Daily emails annoy the one person whose help you need, and they train the client to ignore you. Space your messages as the table shows, and between messages, do nothing. If a client replies with a payment date, stop chasing and diary that date instead.
Tip: Send chases in the morning, on a working day, to the person who approves payments, not just your day-to-day contact. If you only have a general inbox, ask in your first chase who handles supplier payments, and use that name next time.
Before the due date: the friendly heads-up
Most late payments start as simple forgetfulness, a missing purchase order number, or an invoice sitting in the wrong inbox. A pre-due payment reminder catches all three while the tone is still easy, and it often gets you paid before the due date passes at all.
Subject: Quick reminder: invoice [INV-1001] is due on [date]
Hi [Client name],
Just a quick reminder that invoice [INV-1001] for [amount] is due on [date]. I have attached a copy in case it helps.
If payment is already on its way, please ignore this message. If anything on the invoice needs correcting, just reply here and I will sort it straight away.
Thanks,
[Your name]
On the due date and just after it
The due-date email is the shortest in the sequence. Its only job is to mark the day and make paying effortless. Attach the invoice again, include the payment link or payment details, and keep the whole message under five lines where you can.
Subject: Invoice [INV-1001] is due today
Hi [Client name],
Just a reminder that invoice [INV-1001] for [amount] is due today. You can pay here: [payment link].
If you have already sent payment, thank you, and please ignore this note.
Thanks,
[Your name]
Three days later, if nothing has arrived, the tone firms up slightly. You are no longer reminding. You are asking a direct question: when will this be paid? That question is the most useful sentence in any chasing email, because a date is something you can diary, follow up on, and hold the client to.
Subject: Invoice [INV-1001]: 3 days overdue, payment date please
Hi [Client name],
Invoice [INV-1001] for [amount] was due on [date] and I have not received payment yet. Could you confirm when I can expect it?
If there is a query on the invoice, or you need a purchase order number added, tell me here and I will fix it today.
Thanks,
[Your name]
Tip: If the client answers with a date, reply with one line confirming it, then stop chasing until that date passes. Chasing a client who has already given you a date is the fastest way to turn a cooperative payer into an annoyed one.
When the invoice is seriously overdue: the final notice
Fourteen days overdue is the point where politeness alone has done its job. The final notice is still professional, but it is formal, dated, and specific about what happens next. It gives one final deadline, usually seven days, and names the next step plainly. Never bluff about a step you will not take.
Subject: Final notice: invoice [INV-1001], [amount] overdue
Hi [Client name],
Invoice [INV-1001] for [amount] is now 14 days overdue, despite my reminders on [dates]. Please pay in full by [final deadline date], or contact me before that date to agree a payment plan.
If I do not hear from you by that date, I will pass the debt to a debt collection agency or start a court claim, and I will add any interest and recovery costs I am entitled to claim.

In the UK, business-to-business invoices carry statutory rights that strengthen this notice. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can claim late payment interest at 8 percent above the Bank of England base rate, plus fixed compensation of 40 pounds for debts under 1,000 pounds, 70 pounds for debts from 1,000 to 9,999 pounds, and 100 pounds for debts of 10,000 pounds or more. These rights apply automatically to business clients, not to private consumers, and they do not apply if your contract already gives you a substantial remedy of its own. GOV.UK sets out the debt recovery costs rules.
Here is a worked example, so your final notice can state a real figure rather than a vague warning. Take an invoice for 1,850 pounds, paid 30 days late, with the statutory rate for the second half of 2026 at 11.75 percent a year (the 3.75 percent Bank of England base rate on 30 June 2026 plus 8 percent). Interest is 1,850 x 0.1175 x 30 divided by 365, which is 17.87 pounds. Add the 70 pound fixed compensation for a debt in the 1,000 to 9,999 pound band, and the total claim on top of the invoice is 87.87 pounds. If the numbers in your case differ, LancerBill’s late payment fee calculator works them out for you, and our UK late payment fees guide explains the rules in full.
Rates last reviewed: October 2026. The statutory rate changes with the Bank of England base rate, so check the rate in force when the debt fell due before you quote a figure to a client.
Watch out: Do not add interest or compensation to an invoice unless you are entitled to it and can show the arithmetic. A wrong figure in a final notice weakens your position and hands the client a genuine reason to dispute the whole claim.
How do you reply when the client answers?
Match your reply to what the client actually said. A client who says payment is in process needs a confirmation date, not another chase. A client who raises a query needs the corrected invoice or missing detail, not pressure. A client who cannot pay needs a written payment plan with dates. Silence is the only reply that calls for escalation.
| What the client says | What it usually means | Your next move |
|---|---|---|
| “It is in process” or “with finance” | Approved, waiting in a payment run | Ask for the payment run date and the name of the finance contact, then wait until that date |
| “We never received it” | Wrong inbox, spam filter, or a leaver’s address | Resend the invoice in the same thread and ask the client to confirm receipt |
| “The amount is wrong” or “where is the PO?” | A genuine invoice query blocking payment | Fix the invoice or add the reference the same day, then restart the clock from the corrected invoice |
| “We cannot pay in full right now” | Cash flow problem, not necessarily a refusal | Agree a short written plan: dated instalments, the first payment within days, and what happens if a date is missed |
| No reply at all | Ignored, disputed silently, or the contact has moved on | Move to the next stage in the sequence, then to a phone call, then to the final notice |
This reply decoder is the part most template lists skip, and it is where most chasing fails. Templates get you the first email. Knowing what to do with the answer gets you the money. A payment plan deserves a special note: put it in writing, name every instalment date, and state that the full balance becomes due at once if a date is missed. A verbal plan that nobody wrote down is barely a plan at all.
Mistakes that make chasing backfire
Five mistakes undo otherwise good chasing. First, copying in senior managers or threatening legal action in your first email. Escalation is a ladder, and skipping rungs makes you look unreasonable. Second, chasing the wrong person. Your project contact may have no power over payments, so find the finance contact early.
Third, burying the ask. If the client has to read four paragraphs to learn what you want, they will close the email and deal with something simpler. Invoice number, amount, due date, one action. Fourth, apologising for chasing. You delivered work and agreed a price. Asking for it is normal business, and an apologetic tone teaches clients that your invoices are optional.
Fifth, sending a new invoice for every reminder. Reissuing the invoice with a new number creates duplicate records, confuses the client’s accounts payable team, and can double-count the debt. Send the same invoice number every time, and say so. When you need a fresh document, use LancerBill’s invoice generator to create a clean, correctly numbered original, then chase that one number consistently.
Key takeaways
- Chase on a schedule: 3 days before the due date, on the due date, 3 days overdue, and a final notice at 14 days overdue.
- Every chasing email states the invoice number, the amount, the due date, and one clear action.
- Ask for a payment date, not just payment. A date is something you can diary and follow up on.
- Match your reply to the client’s answer: a payment run date, a corrected invoice, or a written payment plan.
- UK business invoices carry statutory interest at 8 percent above base rate plus fixed compensation of 40, 70 or 100 pounds.
- Never bluff about a next step you will not take, and never reissue an invoice under a new number to chase it.
Frequently asked questions
How many chasing emails should I send before taking further action?
Four is the standard sequence: a pre-due reminder, a due-date note, a check-in at 3 days overdue, and a final notice at 14 days overdue. After the final deadline passes with no reply, move to a phone call, a letter before action, or a small claims court claim, rather than sending a fifth email.
Should I charge interest on a late invoice?
For UK business-to-business invoices, you can claim statutory interest at 8 percent above the Bank of England base rate plus fixed compensation, under the Late Payment of Commercial Debts (Interest) Act 1998. For private consumers, interest depends on your contract terms. Check your entitlement and show the arithmetic before adding any figure to a final notice.
What if the client says they never received my invoice?
Resend the invoice in the same email thread, ask for proof of delivery in reply, and check you have the right finance contact. If the original went to a leaver’s inbox or a spam folder, a confirmed resend restarts the conversation cleanly, and you should diary a new follow-up date from the confirmed receipt.
Is it rude to chase an invoice before the due date?
No. A pre-due reminder framed as a helpful heads-up is standard business practice, and most finance teams welcome it because it catches missing references or wrong addresses before the invoice becomes overdue. Keep it short, friendly, and free of any threat, and it will not damage the relationship.
What should I do if a client offers part payment?
Accept it in writing, but agree the rest at the same time: dated instalments for the balance, the first instalment within days, and a term that the full balance becomes due at once if a date is missed. A part payment without a written plan for the balance often becomes the only payment you ever receive.
Can I stop work for a client who has not paid?
Only if your contract or agreed terms allow it, and only after warning the client in writing. Pausing work without a contractual right can itself become a dispute, so check your terms first, give a dated warning, and keep the pause proportionate to the unpaid amount.
For the wider picture, read our guides on invoice payment terms and what to do when clients do not pay, and use LancerBill’s quote generator to agree clear payment terms before the next project starts.
