When payments are overdue, it can strain the client relationship and impact your company’s finances.

In this article, we’ll teach you how to craft courteous emails to remind customers of these past due invoices. Also, we will be offering steps and templates to help you manage this situation professionally and maintain good client relationships.

What Is a Past Due Invoice?

A past due invoice is an unpaid bill for goods or services that remains outstanding beyond its due date. It represents an unfulfilled financial obligation between a business and its customer. When an invoice becomes past due, it means the payment timeframe has expired, and the sum remains unpaid.

It’s important to remain positive when dealing with past-due payments, even if it takes some extra effort.

  1. Assess the situation: Start by reviewing the overdue invoice and any associated agreements. Verify the payment due date, terms, and any late fees that may apply.
  2. Send gentle reminders: Initiate contact with the customer through a polite reminder. A friendly email or a courteous phone call can often resolve the issue without escalation.
  3. Offer flexible payment plans: Consider offering payment plans or extended deadlines if the customer is experiencing financial difficulties. This demonstrates your willingness to work with them.
  4. Escalate communication: If reminders don’t yield results, escalate the communication to a more formal collection notice, clearly stating the consequences of continued non-payment.
  5. Leverage late fees: Enforce late fees as specified in your terms and conditions. Clearly communicate these fees to the customer to motivate timely payment.
  6. Maintain accurate records: Keep detailed records of all communication, including emails, letters, and phone call logs, as well as payment receipts and agreements.
  7. Review and improve processes: Regularly evaluate your invoicing and payment collection processes. Identify weaknesses and make improvements to prevent future past-due invoices.
  8. Seek legal recourse (if necessary): As a last resort, consider taking legal action to recover the debt. Consult with legal experts to understand the steps involved.

Now that you’re equipped with strategies to handle past-due invoices effectively, it’s time to explore another critical aspect—how to craft compelling past-due invoice emails.

How to Write a Past-Due Invoice Email?

It can be a very frustrating process when customers don’t settle their accounts despite reminders and notices. As a collections analyst or a business owner, you understand that the key to success in these situations lies not only in persistence but also in effective communication. This is where crafting compelling past-due invoice emails comes into play. 

These emails serve as vital communication tools, capable of significantly impacting your ability to recover overdue payments while simultaneously preserving positive client relationships. 

To effectively compose a past-due invoice email and decrease bad debts, consider the following steps:

1. Include the invoice number in the subject line

Grab your client’s attention right from the start by making the subject line of your email directly reference the invoice. Incorporate your company name along with the invoice number, which not only provides context but also reminds the client of the pending payment. 

A well-crafted subject line can significantly increase the chances of your email being opened and acted upon.

Some effective subject line examples include:

[Company name – Invoice Number] Regarding an overdue payment

[Company name – Invoice Number] Is a month overdue

[Company name – Invoice Number] Payment required

2. Specify the due date and the amount

Transparency is key when communicating about overdue invoices. Clearly state the invoice due date and the precise amount owed in your email. Use formatting techniques like bolding and spacing to make these details stand out. 

Ensure that the information matches the client’s records and previous communications. This clarity helps eliminate any ambiguity and sets clear expectations.

3. Explain payment options

Make it easy for your client to take action by providing clear instructions on how to make the payment. Include a prominent call to action and, if possible, an online payment link that allows them to enter their banking or card details swiftly. 

Alternatively, provide the address where they can send a check or money order if that’s their preferred method of payment. The objective is to offer a hassle-free way for clients to settle their dues promptly, reducing the need for further reminders.

4. Specify next steps

In cases where clients keep ignoring your communications, it’s essential to outline the next steps clearly. 

Explain your late fee policy, if applicable, and detail the consequences of continued non-payment. This information may serve as a motivation for clients to prioritize clearing their outstanding balances.

Some examples of consequences for non-payment include:

  • Placing the account in bad status
  • Applying additional fees
  • Taking legal action in extreme circumstances
  • While maintaining professionalism, make it evident that non-payment has implications, and prompt action is in their best interest.

By following these steps, you can craft an effective past-due invoice email that not only reminds clients of their financial obligations but also provides them with a straightforward path to resolution. 

Now, let’s take this a step further and explore pre-designed past due invoice email templates that can simplify the process and save you time in your collections efforts.

Past Due Invoice Email Templates

The below templates are designed to help you communicate effectively while maintaining the integrity of your client relationships.

1. Past Due Invoice Email Template (Day 15): Two Weeks Late

If payment hasn’t been received by the due date, it’s a good practice to reach out and confirm whether the invoice has been received on their end. In cases where invoices are only a few days overdue, consider sending a friendly and gentle reminder. Often, this simple nudge is all it takes to prompt payment.

Sample Email

Subject line: [Your Company Name]: Invoice #XXXXX for [Product/Service] is 15 days past due

Dear [Customer’s Name],

I trust this message finds you in good health.

I am writing to bring to your attention the status of Invoice #XXXXX, dated [sent date], with a total amount due of [invoice amount], which is now 15 days past due.

For your convenience, I have attached the invoice [reference number] to this email. To facilitate a smooth payment process, please consider submitting your payment using the [explanation of payment method].

2. Past Due Invoice Email Template (Day 30): One Month Late

When a payment is one month overdue, it’s prudent to follow up, especially if your initial reminder hasn’t yielded a response. Politely calling the customer to confirm receipt of the invoice and addressing any potential questions can be a proactive step.

In many cases, it’s possible that the invoice was overlooked or misplaced. Don’t hesitate to inquire about its status.

If you’ve already engaged with the client and the payment remains outstanding, consider reissuing the invoice, incorporating any additional charges if applicable. However, exercise caution with late payment fees; apply them only if both parties have previously agreed to such terms. Unexpected late fees can potentially create friction with customers.

Sample Email

Subject line: [Your Company Name]: Invoice #XXXXX for [Product/Service] is 30 days past due – Payment is required

Dear [Customer Name],

I have contacted you before requesting a past-due invoice payment for Invoice #XXXXX, but I haven’t heard anything from you.

We are genuinely concerned and want to ensure there are no issues on your end that may be hindering the payment process. If there are any challenges you’re facing or if you require additional information to facilitate the payment, please don’t hesitate to reach out. We are here to assist you.

As of today, Invoice #XXXXX is now 30 days overdue, and, in accordance with our terms, a late fee of [amount] has been applied to your account. To bring your account up to date, we kindly request that you submit your payment at your earliest convenience. You can conveniently make a payment by following this [payment options] link.

This email should be:

– Assertive (Conveying the urgency of the issue)

– Urgent (Emphasizing the need for immediate action)

– Flexible (Open to discussing payment plans if necessary)

Sample Email

Subject line: [Your Company Name]: Invoice #XXXXX for [Product/Service] is 60 days past-due: Need Urgent Payment!!

Hi [Customer’s Name],

This email serves as an urgent reminder that your invoice, #XXXXX, is now 60 days past due, and I need your prompt attention.

– A formal tone that underscores the seriousness of the issue.

– Clarity in articulating the next steps, including the possibility of involving a collection agency or taking legal action.

– Conciseness, with a focus on brevity and clarity to convey the message succinctly.

Sample Email

Hi [Customer’s Name],

Please pay close attention to this important message. There have been several occasions when I have contacted you regarding a payment that has been overdue for 90 days.

Under my payment terms, you may be subject to additional [late fees or interest] if your payment is received more than [number of days] after the due date.

The final deadline for your payment is approaching. If we do not receive your payment by [final date], we will have no choice but to escalate this matter to a collection agency. We genuinely hope to avoid such a course of action and believe that a timely resolution is in the best interest of all parties involved.

Again, if you have any questions or concerns about this payment, please contact me at [contact number]. I hope we can settle this matter as soon as possible.

Best Practices to Keep In Mind While Writing a Past Due Invoice Email

Late payments can indeed be frustrating and detrimental to the growth of your business. However, it’s important to recognize that people are often preoccupied, and financial matters can sometimes slip their minds. When composing a past-due email, it’s crucial to adhere to best practices that ensure clear communication and encourage prompt resolution.

  1. Start early: Initiate contact with your client as soon as the invoice becomes even slightly overdue. Proactivity helps ensure that payments are not forgotten and encourages timely settlement.

  2. Be transparent and clear:When drafting a late payment email, make sure to clearly communicate the originally agreed-upon payment deadlines. Establishing clear expectations from the outset can help prevent misunderstandings down the road.

    Verify contact details: Prior to sharing any financial information, double-check that you have accurate client information, including their email address. Ensuring you’re reaching the correct recipient is vital for effective communication.

  3. Include key information: In your email, include all key details related to the past-due invoice. This should encompass invoice date, invoice number, past due amount, payment terms and any applicable late fees, and contact information.

  4. Attach a copy of the invoice: A best practice is to attach a copy of the original invoice with each overdue payment reminder email. This simplifies the process for the client to review details and verify the information in your message.

  5. Be consistent: Sending a single email reminder sporadically is unlikely to yield results. Create an email flow with multiple contact points and follow-ups. Weekly reminders can be a helpful starting point.

  6. Try other contacts: In some instances, the person you are initially in contact with may not be responsive or available. Don’t hesitate to explore other contacts within the client’s organization to ensure your messages are received and acknowledged.

  7. Mention legal action when necessary: While not ideal, mentioning the possibility of legal action can sometimes expedite resolution. Consult with legal counsel or consider sending a formal warning letter, especially in cases that warrant escalation.

How Automation Can Revolutionize Past Due Invoice Management

Effective management of past due invoices presents a significant challenge for businesses in various industries. Even with dedicated collections teams, the intricacies of handling overdue payments can be daunting. Late payments can disrupt cash flow, hinder growth prospects, and strain client relationships. Moreover, amidst their own busy schedules, clients may unintentionally let invoices slip through the cracks. 

So, how can businesses deal with these challenges and improve their management of overdue payments? The answer is automation. Automation is a solution that can make things easier by streamlining processes, making your business more efficient, and helping you collect payments more consistently and successfully.

Here are several ways in which automation can revolutionize past due invoice management, making it more efficient and less labor-intensive. 

1. AI-based worklist prioritization

Automation leverages cutting-edge AI algorithms to efficiently prioritize customers based on a multitude of factors. These include invoice amounts, aging, credit risk, and historical payment behavior. 

This intelligent system assigns recommended actions to each customer, streamlining the decision-making process for collections teams. By freeing up collectors’ bandwidth automation helps them focus on reaching the right customers at the right time.

2. Automated email correspondence

One of the primary advantages of automation is its ability to eliminate manual tasks. It automatically sends past-due notices by analyzing customer responses and generates follow-up tasks.

Automation empowers collections teams to utilize pre-designed templates for past-due notices and proactive reminders. Additionally, it automatically tracks the status of correspondence, offering valuable insights into customer interactions.

3. In-app dialer

Automation significantly enhances the efficiency of collections teams through streamlined calling processes. It assists with both pre and post-call activities by analyzing past due invoices and summarizing the purpose of the call. 

One-touch calls can be initiated directly from the collections tool, saving valuable time that would otherwise be spent navigating multiple applications. Automation also simplifies call logging, capturing important details from conversations.

4. Web portal collections

Robotic process automation (RPA) plays a pivotal role in the automation of web portal collections. It automatically logs in to A/P portals using customer credentials, allowing organizations to track invoice statuses and record follow-up actions efficiently. 

Additionally, automation identifies and flags missing open invoices, proactively addressing discrepancies. It also automates the handling of promise-to-pay arrangements and disputed invoices, maintaining comprehensive records of disputes.

5. In-app payments

Automation seamlessly integrates digital payment options into correspondence, enabling customers to initiate payments with ease. By incorporating payment links within the communication process, it simplifies and accelerates the payment collection process.

3. How long can an invoice be overdue?

The duration for which an invoice can be overdue depends on the terms and agreements between the parties involved.
