If the invoice remains unpaid on the <a href=\"https:\/\/www.cashontime.com\/en\/articles\/payment-due-dates\/\"><strong>due date<\/strong><\/a>, it becomes a customer receivable due and payable. An overdue invoice that is unpaid has a direct <strong>impact on a company\u2019s cash flow<\/strong>. Indeed, the expected cash inflow did not occur on the scheduled date, which could create timing mismatches and cash flow pressure.<\/p>\n<p>At the same time, managing overdue unpaid invoices requires a tactful approach to <strong>maintain customer relations<\/strong>. To combine effective <a href=\"https:\/\/www.cashontime.com\/en\/articles\/debt-collection\/\"><strong>collection<\/strong><\/a> of overdue invoices with maintaining strong customer relationships, it is essential not only to understand the key levers of effective customer dunnings, but also to master best practices and tools for payment tracking.<\/p>\n<h2>What is an overdue invoice?<\/h2>\n<p>An overdue invoice is an invoice for which the<strong> payment due date has passed<\/strong>, and for which payment has not been received.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignright wp-image-83115 size-medium\" src=\"https:\/\/www.cashontime.com\/wp-content\/uploads\/facture-echue-360x240.jpg\" alt=\"facture echue\" width=\"360\" height=\"240\">In practice, companies can issue invoices for cash payment or negotiate <strong>payment terms<\/strong> with their customers, ranging from 15 to 60 days maximum. Until that period has expired, the customer owes the amount of the invoice, but payment is not yet due. Only when the due date has passed can the company <strong>demand payment<\/strong> from the customer. This is when the invoice becomes <strong>unpaid<\/strong>.<\/p>\n<p>In fact, a distinction is generally made between an <strong>overdue invoice <\/strong>and a <strong>late invoice<\/strong>. In the case of overdue invoices, the payment date has passed, but a grace period applies. This is a to-hold period of a few days to avoid reminding the customer too soon when payment may still be in progress. On the other hand, a late invoice is one that is sufficiently past its due date to <strong>warrant a <a href=\"https:\/\/www.cashontime.com\/en\/articles\/customer-reminder\/\">reminder<\/a><\/strong>.<\/p>\n<p>In light of these definitions, it is easy to see the <strong>financial consequences<\/strong> of an increase in the number of outstanding invoices or poor management of <a href=\"https:\/\/www.cashontime.com\/en\/articles\/trade-receivables\/\"><strong>customer receivables<\/strong><\/a>.<\/p>\n<h2>Why is it important to manage overdue invoices?<\/h2>\n<p><img decoding=\"async\" class=\"alignright wp-image-83121 size-medium\" src=\"https:\/\/www.cashontime.com\/wp-content\/uploads\/retards-paiement-1-360x202.jpg\" alt=\"retards paiement\" width=\"360\" height=\"202\">As part of its financial management, and more specifically its cash flow, the company forecasts cash inflows based on the amounts and payment dates of issued invoices. However, if invoices are paid late, this can lead to <strong>cash flow gaps<\/strong>, which in turn can cause significant pressure. The company may then find it difficult to pay its own invoices, due to a <strong>lack of liquidity in its accounts<\/strong>. If this situation is repeated on a large scale, it can even lead to the company\u2019s <strong>insolvency<\/strong>.<\/p>\n<p>As a result, it is vital for the company to <strong>manage overdue invoices properly<\/strong>, to have the most accurate financial visibility possible, and to ensure its financial stability.<\/p>\n<p>On the other hand, properly managing overdue invoices helps <strong>maintain healthy customer relationships<\/strong>. By establishing a clear, mutually accepted framework and having a <strong>well-managed dunning process<\/strong>, you can ensure that the commercial relationship is maintained under good conditions, while still securing payment.<\/p>\n<p>What is more, it saves finance and sales teams a great deal of time and efficiency.<\/p>\n<h2>How to collect an overdue invoice?<\/h2>\n<p>When you detect an overdue invoice, it is important to <strong>react quickly<\/strong>. The sooner you start tracking invoices and initiating dunning, if applicable, the higher your chances of collecting payment. This is also an excellent way of <strong>reducing DSO<\/strong> (Days Sales Outstanding). However, it is important not to follow up with the customer too early, as it is possible that the transfer is already in progress, for example, and the customer could be offended by being reminded \u201cwithout reason\u201d. Consequently, it is important to adopt the right timing, but also the right tone, for effective reminders from both a financial and commercial point of view. That is why we strongly recommend setting up a <strong>structured and prioritized dunning plan<\/strong> based on the customer\u2019s profile, the amount at stake, and the number of days overdue. To maximize your chances of success in the customer dunning phase, you can also <strong>vary your communication channels<\/strong>. For example, a telephone or email reminder may be enough in the first place. A mail reminder may be useful if the customer fails to react.<\/p>\n<p><img decoding=\"async\" class=\"alignright wp-image-83119 size-medium\" src=\"https:\/\/www.cashontime.com\/wp-content\/uploads\/facture-impayee-360x218.jpg\" alt=\"facture impayee\" width=\"360\" height=\"218\"><\/p>\n<p>It is important to note that customer reminders are not required by law as part of an amicable collection procedure. However, in practice, this step is virtually unavoidable. On the one hand, it helps <strong>maintain contact with the customer<\/strong>, and on the other hand, it avoids incurring unnecessary costs if the customer has simply forgotten to pay, or sent the check awaiting receipt, for example.<\/p>\n<p>If <strong>dunning attempts fail<\/strong> and you are considering initiating legal collections proceedings, you will need to <strong>send a formal demand letter<\/strong>. This is a registered letter with acknowledgement of receipt, reminding your customer of his payment obligations. It refers to the unpaid invoice, mentioning its number, amount, initial payment date, etc. The demand letter serves to initiate the <strong>calculation of interest and penalties for late payment<\/strong>. The customer must be given a reasonable period of time to rectify the situation. Generally speaking, this period is 15 days.<br>If the situation is not rectified within the allotted time, the case can be brought before the court by means of various legal procedures, ranging from an <strong>injunction to pay<\/strong> to a<strong> summons to pay<\/strong>.<\/p>\n<p>In addition, the success of the collection process for overdue invoices depends on the cooperation of the accounting and sales departments.<\/p>\n<h2>Best practices for efficiently managing overdue invoices<\/h2>\n<p>The first thing to do to manage overdue invoices effectively is to refer to your company\u2019s <strong>collections policy<\/strong>. This should include a clear internal process outlining follow-up actions, required deadlines, prioritization rules, and the different types of follow-ups to be carried out.<\/p>\n<p>Next, it is important to train <strong>both accounting and sales teams<\/strong> in customer dunning and collections procedures. This plays an important part in maintaining communication with the customer, and preserving the relationship, while obtaining payment as quickly as possible.<\/p>\n<p>Another best practice for efficiently managing overdue invoices is to <strong>adopt collections software<\/strong> that will allow you to:<\/p>\n<ul>\n<li><strong>centralize information<\/strong> and track invoices and overdue payments,<\/li>\n<li><strong>receive automatic alerts<\/strong> to react at the right time and avoid oversights,<\/li>\n<li><strong>automate dunning <\/strong>to save time and make the process more reliable,<\/li>\n<li><strong>access comprehensive dashboards<\/strong> updated in real time for precise management,<\/li>\n<li><strong>analyze reports<\/strong> to monitor results and adjust financial strategy accordingly.<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><a data-obflink-url=\"aHR0cHM6Ly93d3cuY2FzaG9udGltZS5jb20vZW4vZHVubmluZy1yZWNvdmVyeS1yZWNlaXZhYmxlcy8=\" class=\"bouton vert\" tabindex=\"0\">DISCOVER CASHONTIME SOFTWARE<\/a><\/p>\n<h2>Conclusion<\/h2>\n<p>Managing overdue invoices plays a central role in a company\u2019s financial management.
