What if the customer says they will pay but does not?

Confirm the promise in writing, then follow up the day after the promised date. After two missed promises, treat the account as a collection risk.

Late payment email templates

Most overdue invoices are paid after the second or third reminder. Tone matters more than wording. The four emails below escalate calmly without burning the relationship until the final stage.

When to use

Day 0 (due date) — friendly reminder, automated.
Day +3 — short personal note from a real person.
Day +10 — firm but professional, references late-fee policy.
Day +21 — final notice before further action.

Examples

Day 0 — friendly reminder

Subject: Reminder — invoice {invoice_number} due today

Hi {first_name},

Just a quick note that invoice {invoice_number} for {amount} is due today. If it is already on its way, please ignore this — bank timings vary.

Payment link: {payment_link}
Bank details and PDF: attached.

Thanks,
{your_name}

Calm, specific, gives them an out. Most invoices clear after this email.

Day +3 — personal nudge

Subject: Quick check on invoice {invoice_number}

Hi {first_name},

I haven't seen invoice {invoice_number} ({amount}) clear yet — anything I can help with on your side? Sometimes these get stuck in approvals or the PDF doesn't make it through to the right person.

Happy to resend or split it differently if it helps.

Thanks,
{your_name}

Assumes good faith. Asks if there is something to fix. Buyers respond well because it is not accusatory.

Day +10 — firm but professional

Subject: Overdue — invoice {invoice_number} ({days_overdue} days)

Hi {first_name},

Invoice {invoice_number} for {amount}, originally due {original_due_date}, is now {days_overdue} days overdue. Could you confirm a payment date this week?

For reference, our standard terms include statutory interest on overdue balances after 30 days.

Payment link: {payment_link}
PDF re-attached.

Thanks,
{your_name}

Restates facts, asks for a confirmed date, mentions interest without threatening.

Day +21 — final notice

Subject: Final notice — invoice {invoice_number}

Hi {first_name},

Invoice {invoice_number} for {amount} is now {days_overdue} days past the original due date of {original_due_date}, despite previous reminders on {reminder_dates}.

Unless we receive payment or a written payment plan by {final_deadline}, we will pause new work and proceed with formal recovery options, including statutory interest and any costs incurred.

If there is a genuine issue, please reply today and we will work it out.

Regards,
{your_name}

Specific deadline, references prior reminders, gives them one last chance to resolve before escalation.

Tips

Send each reminder from a real person, not a no-reply address. Replies should reach you immediately.
Always re-attach the PDF or include the share link. Do not assume the buyer still has it.
Document each reminder — date, content, response. This is your evidence trail if escalation is needed.
Pause new work after the third reminder. Continuing to deliver is how SMBs end up with five-figure write-offs.
