Have you ever faced the frustration of unpaid invoices disrupting your cash flow? Managing these delicate situations requires tact and strategy to preserve both your cash flow and business relationships. In this article, we will explore effective strategies for chasing unpaid invoices, adapted to all phases of the process, from friendly reminders to legal action. Discover how to transform these moments of tension into opportunities to strengthen trust with your clients.

Why is it crucial to follow up on an unpaid invoice?

Following up on an unpaid invoice is not simply a matter of recovering funds; it’s a necessity to ensure the financial health of your business. Proactive management of unpaid invoices helps you:

  • Maintaining a stable cash flow: every unpaid invoice is a loss of income that affects your ability to meet current expenses.
  • Preserve the client relationship: a well-conducted follow-up demonstrates your professionalism and commitment to sound business practices.
  • Anticipate financial risks: quickly identifying payment issues allows you to take measures before the situation worsens.

What are the impacts of an unpaid invoice on a company's cash flow?

The repercussions of an unpaid invoice on a company’s cash flow can be considerable and diverse:

  • Slowing of cash flows: capital intended for other expenses or investments remains blocked.
  • Increase in financial costs: the need to resort to external financing to fill the gap can lead to additional costs.
  • Impact on working capital: a longer cash conversion cycle reduces your company’s operational efficiency.


By becoming aware of these impacts, you understand the importance of implementing an effective and respectful follow-up strategy.

First steps towards effective follow-up

Initiating a follow-up procedure may seem delicate, especially if you want to maintain good relationships with your clients. However, identifying the ideal moment and preparing your approach are key steps to ensure the effectiveness of your actions.

How to identify the ideal moment to start chasing an unpaid invoice?

The timing of the follow-up is crucial to maximize your chances of recovering funds while maintaining a positive relationship with the client. Here’s how to determine the ideal moment:

  • Monitor the due date: start by noting the agreed payment date and be vigilant as it approaches.
  • Evaluate the client’s payment habits: if a client historically has delays, anticipate an earlier follow-up.
  • Intervene quickly: a follow-up made shortly after the due date shows your seriousness in payment management.

What are the preliminary steps to take before chasing an unpaid invoice?

Carefully preparing your follow-up will increase your chances of success without compromising the client relationship. Here are the essential preliminary steps:

  • Verify the invoice details: ensure that all information is correct and that nothing justifies the payment delay.
  • Document all communications: keep a history of previous exchanges with the client regarding the invoice
  • Prepare your argument: be ready to explain clearly and firmly, but politely, why the follow-up is necessary and urgent.


By following these steps, you ensure that the follow-up is justified and that you are ready to handle the situation professionally and effectively.

Friendly follow-up techniques

Chasing an unpaid invoice while preserving a good relationship with your clients requires finesse and a keen sense of communication. Here’s how to approach the situation with tact and professionalism.

How to follow up on an unpaid invoice while preserving the client relationship?

The key to maintaining a good client relationship while following up on an unpaid invoice is diplomacy. Follow these tips for an effective approach:

  • Be courteous and professional: Always start your communications with a polite greeting and an expression of gratitude for the business relationship.
  • Clearly explain the situation: Specify the details of the unpaid invoice, including the past due date, and politely request an update on the payment status.
  • Offer solutions: Propose payment arrangements or ask if the client needs assistance to resolve the issue.

Escalating to stricter measures

When friendly reminders are not enough, it may be necessary to take stricter measures to ensure payment of unpaid invoices. Here’s how to proceed with this escalation effectively and professionally.

When and how to move to a registered letter reminder?

If your initial email reminders have not been successful, moving to a registered letter is a logical step to formalize your request:

  • After several unanswered reminders: Generally, if two reminder emails have been ignored, it’s time to move to a registered letter.
  • Use a formal tone: Write a letter that clearly expresses the need for payment while remaining professional and respectful.
  • Send it by registered mail with acknowledgment of receipt: This will ensure you have proof of sending and receipt of your letter.

What actions to take for a third reminder and beyond?

When the first approaches have not been fruitful, you can intensify your efforts while staying within the legal framework:

  • Third reminder by phone: A direct call can help clarify the situation and push the client to settle their debt.

  • Formal notice: If payment is still not made, send a formal notice by registered mail, marking the beginning of potential legal measures.

  • Prepare for legal action: As a last resort, consult a lawyer to discuss legal options, such as a payment order or summons to court.

Moving to legal action

When friendly reminders and strict measures have not led to the settlement of unpaid invoices, it may be necessary to move to legal action. This represents an important step that requires thorough consideration and, often, the intervention of legal experts.

At what point should you consider a formal notice or legal action?

The decision to move to legal measures should be taken after several unsuccessful attempts at amicable recovery:

  • After several unsuccessful reminders: If your registered letters and calls remain unanswered, it’s time to consider more serious actions.
  • Evaluation of the client’s financial situation: Ensure that the client is solvent. Legal action against an insolvent company could be futile.
  • Consultation with a lawyer: Before sending a formal notice, it is wise to consult a lawyer specializing in debt collection to assess your options and associated risks.

What are the legal procedures available for unpaid debts?

Several legal options are at your disposal to recover unpaid debts, each adapted to different scenarios and debt amounts:

  • Payment order: Simplified and quick procedure to obtain an enforceable title without going through a trial, suitable for uncontested debts.
  • Interim payment order: Allows you to ask the court for an advance on the amounts due, ideal when the debt is not seriously contestable.
  • Dation in payment: Initiates a formal lawsuit, suitable for complex disputes or high amounts, where both parties are called to present their case before a judge.

Each option requires rigorous preparation of documents and a clear understanding of legal procedures. Guidance from a legal professional is strongly recommended to navigate this process and ensure compliance with all legal requirements while maximizing your chances of recovery.

Invoice reminder tools and automation

Automating unpaid invoice reminders can greatly improve the efficiency of your financial processes, while reducing the time spent on repetitive administrative tasks. By using invoice automation software, you can not only save time but also ensure constant and personalized follow-up for each client, without additional effort. Let’s explore together the tools that can help you in this approach and how to choose them wisely.

Which tools can automate and simplify the invoice reminder process?

To automate reminders, several software solutions are available on the market:

  • Accounting and billing software: Tools like QuickBooks, FreshBooks, and Xero integrate payment tracking and automatic payment reminder sending features.

  • ERP systems: Enterprise Resource Planning systems such as SAP and Oracle offer advanced modules for credit and collections management.

  • Specialized reminder management platforms: Solutions like Sellsy or Acomba are specially designed to simplify the management of unpaid invoices, allowing personalized reminders based on customer payment behavior.

How to choose the right tools to set up your reminder plan?

Choosing the appropriate tool for managing reminders requires careful evaluation of your specific needs:

  • Assess your needs: Determine the frequency of your invoicing, the volume of your transactions, and the specifics of your reminder process.

  • Compare features: Ensure that the tool offers key features such as customization of reminder messages, integration with your accounting system, and the ability to generate detailed reports.

  • Consider user experience: The tool should be easy to use for your teams to optimize adoption and efficiency.
