When to Start Chasing

Most late payments aren't malicious — they're typically caused by oversight, administrative backlogs, or cash flow issues on the client's side. Your approach should reflect this reality while still protecting your interests.

Before the due date: Send a friendly reminder 2-3 days before payment is due. This isn't chasing — it's good client service. Many payments happen because of this gentle nudge.

Day 1 overdue: Send your first payment reminder. Keep it light and assume good faith. The invoice may simply have been overlooked.

Day 7 overdue: Follow up more firmly. Request a specific response or payment date.

Day 14 overdue: Escalate to a final notice. Mention late payment interest and potential consequences.

Day 21+ overdue: Pick up the phone. Email clearly isn't working.

Throughout this process, keep records of every communication. If you eventually need to pursue legal action, a clear paper trail strengthens your case significantly.

First Reminder (Gentle)

Your first reminder should be helpful rather than demanding. Assume the invoice was simply overlooked or lost in a busy inbox.

📧 Email Template: First Reminder (Day 1-3 Overdue)

Subject: Friendly reminder: Invoice #[NUMBER] now due

Hi [Name],

I hope you're well! Just a quick note to let you know that invoice #[NUMBER] for £[AMOUNT] was due on [DATE].

I've attached another copy in case the original went astray. If you've already processed the payment, please ignore this message — bank transfers can take a day or two to appear.

If you have any questions about the invoice, just let me know.

Best regards,
[Your name]

Key elements of the first reminder:

  • Friendly, non-accusatory tone
  • Assumes good faith and offers an excuse (invoice may have been missed)
  • Attaches the invoice again for convenience
  • Opens the door for questions or issues
  • No mention of late fees or consequences

This gentle approach works in the majority of cases. Most clients will respond with an apology and immediate payment, or an explanation of when payment will be made.

Second Reminder (Firmer)

If your first reminder goes unanswered, your second message should be more direct. It's clear now that this isn't a simple oversight.

📧 Email Template: Second Reminder (Day 7-10 Overdue)

Subject: Payment overdue: Invoice #[NUMBER] — action required

Hi [Name],

I'm following up on my previous message regarding invoice #[NUMBER] for £[AMOUNT], which was due on [DATE] and is now [X] days overdue.

I haven't received payment or any response to my earlier reminder, so I wanted to check if there's an issue I should know about.

Could you please let me know:

  • When I can expect payment, or
  • If there's any problem with the invoice that's preventing payment

I'd appreciate a response by [DATE — give 2-3 days] so we can resolve this promptly.

Kind regards,
[Your name]

Key elements of the second reminder:

  • More direct subject line indicating action is required
  • References the previous unanswered message
  • Asks for specific information (payment date or explanation)
  • Sets a deadline for response
  • Still professional but clearly expects action

At this stage, you may also want to consider whether to pause any ongoing work for this client. Continuing to deliver while they ignore payment requests sends the wrong message.

Final Notice

The final notice is your last step before escalating to formal debt recovery. It should be firm, factual, and clearly outline consequences.

📧 Email Template: Final Notice (Day 14+ Overdue)

Subject: FINAL NOTICE: Invoice #[NUMBER] — £[AMOUNT] overdue

Dear [Name],

This is my final notice regarding invoice #[NUMBER] for £[AMOUNT], which was due on [DATE] and is now [X] days overdue.

Despite previous reminders on [DATE 1] and [DATE 2], I have received neither payment nor any communication explaining the delay.

If I do not receive payment or a substantive response by [DATE — 7 days from now], I will:

  • Add statutory interest at 8% above the Bank of England base rate, as permitted under the Late Payment of Commercial Debts legislation
  • Apply debt recovery compensation of £[40/70/100, based on invoice size]
  • Consider formal debt recovery proceedings

I would prefer to resolve this directly and maintain our professional relationship. Please contact me immediately to arrange payment.

Regards,
[Your name]
[Phone number]

Key elements of the final notice:

  • Clear "FINAL NOTICE" label
  • Factual summary of the situation and previous attempts
  • Specific consequences with legal references
  • Final deadline for response
  • Door left open for resolution
  • Phone number included (making contact easy)

Send this email at the start of the working week when it's likely to be read promptly. Consider also sending by recorded delivery letter — this demonstrates seriousness and provides legal proof of delivery.

Phone Call Scripts

If emails aren't working, a phone call often cuts through. Many people avoid emails but will engage when called directly. Be prepared, stay calm, and focus on resolution.

Before calling, prepare:

  • Have the invoice details in front of you
  • Note your previous communication attempts and dates
  • Decide what outcome you want from the call
  • Be ready to take notes

📞 Phone Script: Professional but Firm

"Hi [Name], this is [Your name] from [Your business]. I'm calling about invoice #[NUMBER] for £[AMOUNT], which is now [X] days overdue.

I've sent a few emails about this but haven't heard back, so I wanted to check in directly. Is there an issue with the invoice I should know about?"

[Listen to their response]

"I understand. When can I expect payment to be processed?"

[Get a specific date]

"Great, I'll note that down. I'll send a quick email confirming what we've discussed. If there are any problems hitting that date, please let me know in advance."

If they avoid commitment:
"I really need a specific date. If there's a cash flow issue, perhaps we can discuss a payment plan. But I do need to know when the payment will be made."

If they become defensive or hostile:
"I'm not trying to cause difficulty — I just need to be paid for work I've delivered. Can we focus on finding a solution that works for both of us?"

Always follow up a phone call with an email summarising what was agreed. This creates a written record of any commitments made.

Maintaining Relationships

Chasing payment doesn't have to damage client relationships. In fact, handling it professionally can strengthen mutual respect. Here's how to balance firmness with relationship preservation:

Assume good faith first:
Most late payments aren't deliberate. Start gentle and escalate gradually. Jumping straight to threatening language damages relationships unnecessarily.

Separate the payment issue from the work:
You can be firm about payment while still being warm about the project. "The work we did together was great, and I'd love to work with you again — but I do need this invoice sorted."

Give them an out:
Sometimes clients are embarrassed about cash flow problems. Offering payment plans shows understanding while still getting you paid.

Be consistent, not emotional:
Follow your process systematically. Don't send angry emails at midnight. Professional, consistent communication is more effective than emotional outbursts.

Know when to walk away:
Some clients will never pay on time. If late payment becomes a pattern, consider whether the relationship is worth maintaining. Your time has value — spending it chasing invoices has a cost.

Document everything:
Keep records of all communication. If the relationship does sour, you'll have evidence of your professional conduct.

💡 Red Flags to Watch For

These behaviours may indicate a client who will be consistently problematic:

  • Repeatedly promising payment that doesn't arrive
  • Avoiding all communication
  • Suddenly finding problems with completed work when payment is due
  • Blaming internal processes repeatedly
  • Asking for significant additional work before settling existing invoices

Remember: requesting payment for work you've delivered isn't rude, unprofessional, or pushy. It's a normal part of running a business. Clients who respect you will understand this.
