How to Chase an Unpaid Invoice Without Sounding Pushy
Chasing an unpaid invoice feels awkward for most tradespeople, so the reminder either doesn't get sent at all or comes out too sharp when it finally does. Neither helps. The fix is to decide the tone in advance, in three fixed stages, so you're never composing an angry email in the moment. Each stage below has a short example you can adapt, getting a little firmer each time without ever tipping into something you'd regret sending.
Why the tone matters
Most late payers are disorganised, not dishonest, and treating the first reminder as an accusation usually backfires. A calm, assume-good-faith message gets paid faster than an aggressive one, because it gives the customer an easy way to put it right without losing face. Save the firmness for later stages, once a pattern is clear rather than assumed.
The three stages
Stage one is a friendly nudge sent a few days after the due date. Stage two is a firmer written reminder, sent one to two weeks later, that references the original invoice number and terms directly. Stage three is a final notice with a clear deadline, sent if stage two goes unanswered, that states plainly what happens next if payment still doesn't arrive. Space the three out sensibly. Sending all three inside a week reads as pressure; spreading them over too long reads as indifference.
Stage 1: the friendly nudge
Subject: Invoice #1042, just a quick check
Hi [Name], hope all's well since we finished the job. Just flagging that invoice #1042 for £[amount], due on [date], doesn't seem to have come through yet, might have slipped through. Let me know if you need anything from me to get it sorted. Thanks, [Your name]
Stage 2: the firmer reminder
Subject: Invoice #1042 is now overdue
Hi [Name], following up on invoice #1042 for £[amount], which was due on [date] and is now [X] days overdue. I've attached the original invoice again for reference. Could you confirm when I can expect payment? Happy to talk if there's a query with the work itself. Thanks, [Your name]
Stage 3: the final notice
Subject: Final notice: invoice #1042
Hi [Name], invoice #1042 for £[amount] is now [X] days overdue and I haven't had a response to my last two reminders. If payment isn't received by [date], I'll need to look at the next steps to recover the debt, which I'd rather not do. Please get in touch before then if there's a reason for the delay. Regards, [Your name]
If stage three passes without payment or a satisfactory reply, that's the point to move on to the escalation steps, including the small claims route for smaller sums, covered in our guide on what to do when a client won't pay an invoice.

How soon should I send the first payment reminder?
A few days after the due date is usually right. It is early enough to catch a genuine oversight and late enough that it doesn't feel premature. Waiting weeks just gives the impression the deadline wasn't real.
Should invoice reminders be by email or phone?
Email first, because it creates a written record you may need later and lets the customer act without an awkward call. A phone call can work well as a follow-up if email goes quiet, but confirm anything agreed on the call back in writing.
How many reminders should I send before escalating?
Two is typical: a friendly nudge, then a firmer written reminder if that doesn't work. A third, final notice sets a clear deadline before you consider the formal steps covered in our guide on what to do when a client won't pay.
Will chasing an invoice damage the relationship with a good client?
A polite, professional reminder rarely does. Most reasonable clients expect to be asked for money that's overdue and would rather have a quiet nudge than an awkward silence. It's the tone, not the act of chasing, that makes the difference.
