How to chase an unpaid invoice politely
Most unpaid invoices sit behind busyness, not refusal. What to send, when to phone, and how to chase without costing yourself the customer.
The work is done, the invoice went out, and now it is quiet. Chasing it feels rude, so it sits there, and the money sits with it. Most people running a small service business have at least one invoice in exactly that state right now.
The awkwardness rests on a guess: that they have seen it, decided not to pay, and a reminder will start an argument. That guess is nearly always wrong, and once you drop it, chasing gets much easier to do and much harder to get wrong.
Silence is rarely a refusal
Somebody who was happy with the work on Friday does not usually become somebody refusing to pay for it by the end of the month. Far more often the invoice is sitting unread under everything else, or it was opened, mentally filed for payday, and forgotten. Busyness, not bad faith.
An invoice sent as an attachment tells you nothing after it leaves, so every chase is a guess, and guessing is what makes it feel like pestering. An invoice sent as a link can tell you whether it has been opened, and that one fact tells you which message to write.
- Not opened. It has not reached them yet in any real sense. A short nudge is you doing them a favour, and it should read like one.
- Opened, and not paid. They know. Something is in the way, and it is more likely to be payday, a holiday or plain forgetting than it is to be your bill. The reminder is about timing, not persuasion.
One reminder, in words you would actually say
The way out of chasing feeling rude is not to steel yourself and send a sequence. You have been on the receiving end of a five-email chase and you know what it did to your opinion of the sender. Send one, shortly after the due date passes, and make it sound like you.
Something like this does the whole job, and you are welcome to it:
“Hi Sam, hope the bathroom is behaving itself. Just a nudge on the invoice, which was due last Friday. If it has already gone, ignore me. If anything on it needs sorting, give me a ring and I will put it right. Thanks.”
It works because it names the job rather than the debt, assumes good faith, gives them an easy out if payment is already moving, and opens a door for a query instead of a standoff. If a week goes by and nothing happens, ring them. A call is harder to overlook than an email, and it is much easier to stay friendly in.
If it goes properly quiet
Most invoices never get here. When one does, put it in writing, plainly: the amount, the date it was due, and a specific date you are asking for payment by. Keep the tone level. You are not accusing anybody of anything, you are doing the paperwork.
If your customer is another business, the law is on your side: you are entitled to statutory interest and compensation on late commercial payments, and the government's guidance sets out how it works and how to calculate it. Naming that entitlement in a letter is often enough on its own. It belongs in the genuinely stuck cases, not in week two.
Stop it depending on you remembering
The real cost of an unpaid invoice is not just the money. It is knowing what is outstanding without adding it up, remembering who has been nudged and who has not, and carrying all of it around in your head after the day's work is done.
That routine is the part software can honestly take over. Invoices sends the invoice as a link, so you can see whether it is sent, opened, overdue or paid, and if it goes overdue it sends one polite reminder, in words you set, then stops the moment it is paid. Not a sequence, for the same reason you would not send one yourself.
The short version
- Assume busyness before bad faith. It is nearly always the truth, and it makes the chase easier to write.
- Send one reminder shortly after the due date, in your own words, with an easy out.
- If a week passes, phone. Friendlier than a second email, and harder to overlook.
- Escalate in writing only when it is genuinely stuck, and if the customer is a business, statutory interest is there if you need it.
- Take the remembering off yourself, so the chase happens whether or not you are busy.
