What do you say when chasing an overdue invoice?

  • Posted by: Friso van de Beeten

When chasing an overdue invoice, start with a polite but direct approach that includes all payment details and a clear deadline. Your message should maintain professionalism while acknowledging the overdue status. As payments become increasingly late, gradually escalate your tone from friendly reminders to formal demand letters. Each communication should build urgency while preserving the business relationship where possible.

What should you include in your first payment reminder?

Your first payment reminder should include the original invoice number, amount due, original payment terms, and number of days overdue. Always maintain a professional but friendly tone that assumes the delay might be an oversight. Include a specific new deadline for payment, typically 7–10 days from the reminder date.

Start with a polite opening that acknowledges your ongoing business relationship. Reference the specific invoice details clearly so there’s no confusion about which payment you’re requesting. Include the original invoice as an attachment to make it easy for them to process the payment immediately.

Keep your language professional but not aggressive at this stage. Phrases like “We notice that payment for invoice #12345 appears to have been overlooked” work better than accusatory language. Always end with a clear call to action, such as “Please arrange payment by [specific date] or contact us if there are any issues with this invoice.”

Make sure you include your preferred payment methods and any relevant payment details. This removes barriers and makes it as easy as possible for the customer to settle their account promptly.

How do you escalate your language when payments are really late?

When payments are significantly overdue, shift from assuming oversight to expressing concern about the delay. Use more direct language such as “This payment is now 30 days overdue” rather than gentle suggestions. Introduce consequences such as late fees or credit holds while maintaining professional courtesy.

Your second reminder should acknowledge that this isn’t the first communication and express disappointment that the matter remains unresolved. Use phrases like “Despite our previous reminder” to show you’ve been patient but are now taking the matter more seriously.

Include specific consequences that will apply if payment isn’t received by your deadline. This might include late payment charges, suspension of credit terms, or a requirement for payment before future deliveries. Be clear about these consequences but avoid threatening language.

Consider requiring a response even if they cannot pay immediately. Ask them to contact you to discuss payment arrangements if they’re experiencing difficulties. This shows you’re willing to work with them while maintaining pressure for resolution.

What’s the difference between friendly reminders and formal demand letters?

Friendly reminders assume good faith and treat the overdue payment as a possible oversight, using conversational language and maintaining warmth. Formal demand letters acknowledge deliberate non-payment, use legal terminology, and clearly state consequences including potential legal action if payment isn’t received.

Friendly reminders typically go out 7–14 days after the due date and focus on making payment easy. They include helpful information such as payment methods and assume the customer wants to pay but may have forgotten or encountered an administrative delay.

Formal demand letters usually follow 30–60 days of non-payment and failed friendly approaches. They include legal language such as “formal notice” and “demand for payment.” These letters often mention potential legal action, debt collection procedures, or credit reporting consequences.

The formatting also differs significantly. Friendly reminders can be emails or informal letters, while formal demands should be printed on letterhead, sent by recorded delivery, and kept for legal records. Formal demands often include specific legal timeframes, such as “Payment must be received within 14 days of this notice.”

How do you handle difficult conversations about overdue payments?

Stay calm and professional regardless of the customer’s response, focusing on facts rather than emotions. Listen to their explanation without interrupting, then work together to find a realistic payment solution that protects your cash flow. Document everything discussed and follow up with written confirmation of any agreements.

Prepare for the conversation by having all relevant information ready, including payment history, original terms, and your bottom line for acceptable payment arrangements. This preparation helps you respond confidently to questions or objections.

When customers offer excuses, acknowledge their situation without accepting responsibility for their problems. Phrases like “I understand this is difficult, but we also have commitments to meet” show empathy while maintaining your position.

Focus on solutions rather than blame. If they can’t pay the full amount immediately, discuss partial payments or extended terms that work for both parties. Always set specific dates and amounts, and explain what happens if they don’t meet the agreed schedule.

End every conversation with a clear summary of what was agreed and when you expect the next payment or contact. Send a written confirmation within 24 hours to avoid misunderstandings later.

What automation tools can help you chase payments more effectively?

Automated payment reminder systems send consistent, professional messages at predetermined intervals without manual effort. These tools integrate with your accounting software to track due dates and automatically escalate communications as payments become increasingly overdue. They ensure no invoices slip through the cracks while maintaining professional relationships.

Modern automation platforms can personalise messages based on customer history, payment patterns, and relationship status. They’ll send different message sequences to long-term reliable customers versus new or problematic accounts, ensuring appropriate tone and timing for each situation.

The best systems include multiple communication channels such as email, SMS, and even WhatsApp, increasing the likelihood that customers see and respond to payment reminders. They also provide dashboards showing which customers are overdue, what stage of the collection process they’re at, and which communication methods are most effective.

Automation saves significant time by handling routine follow-ups, allowing your team to focus on complex cases that need personal attention. Most businesses find that consistent, timely automated reminders actually improve customer relationships by providing clear expectations and reducing the need for awkward phone calls.

Look for systems that integrate with your existing accounting software and offer customisable message templates that match your brand voice. The investment in proper automation typically pays for itself through faster payments and reduced administrative costs. We have seen businesses reduce their average payment time significantly while maintaining positive customer relationships through well-implemented automation systems.

Frequently Asked Questions

How long should I wait before sending the first payment reminder?

Send your first reminder 7-10 days after the payment due date. This gives customers time to process payments while showing you're actively managing your accounts receivable. Waiting too long can signal that late payments are acceptable and may encourage further delays.

What if a customer claims they never received the original invoice?

Always resend the invoice immediately and confirm their correct contact details. Use this as an opportunity to establish a reliable communication process for future invoices. Consider implementing delivery confirmation for important invoices and maintain records of when and how invoices were sent.

Should I charge late payment fees, and how much is reasonable?

Yes, late payment fees encourage prompt payment and compensate for your additional collection efforts. Typical fees range from 1-3% per month or a flat fee of €25-50, depending on your industry and invoice amounts. Ensure your payment terms clearly state these fees upfront to make them legally enforceable.

When should I involve a debt collection agency or solicitor?

Consider professional collection services when payments are 60-90 days overdue and your internal efforts have failed. For larger amounts (typically over €1,000), legal action may be worthwhile, but factor in costs and the likelihood of recovery. Maintain detailed records of all communication attempts to support any legal proceedings.

How do I handle customers who repeatedly pay late but eventually settle their accounts?

Implement stricter payment terms for chronic late payers, such as requiring payment upfront or reducing credit limits. Consider offering early payment discounts to incentivise prompt payment. Document their payment pattern and consider whether the ongoing administrative costs outweigh the business value.

What should I do if a customer disputes the invoice amount or quality of work?

Address disputes immediately and separately from payment collection. Acknowledge their concerns, investigate thoroughly, and work toward a fair resolution. Consider accepting partial payment for undisputed portions while resolving the disputed amount. Clear project documentation and terms of service help prevent and resolve disputes more effectively.

How can I prevent payment delays from happening in the first place?

Implement clear payment terms, send invoices immediately upon completion, and require upfront payments or deposits for new customers. Use automated invoicing systems, offer multiple convenient payment methods, and conduct credit checks on larger accounts. Regular communication throughout projects also helps identify potential payment issues early.
