How can you improve your DSO? Optimize debt collection, but that’s not all!

Why improve your DSO?

Working capital requirement (WCR) is a company’s capital requirement corresponding to the time lag between cash outflows (payment of purchases) and inflows (payment of sales). It therefore represents the capital required to finance a company’s operating cycle. WCR can be expressed as an amount or as a number of days.

If calculated in days (DWC: Days Working Capital), WCR is the result of three indicators:
DSO (Days Sales Outstanding): number of days before receiving payment from the customer
– DIO (Days Inventories Outstanding): number of days an item remains in stock
– DPO (Days Payable Outstanding): number of days before paying suppliers

In this article we will look specifically at DSO[vc_empty_space height=”30″][vc_column_text el_class=”orange”]

Role and calculation of DSO

[/vc_column_text][vc_empty_space height=”20″][vc_column_text]

DSO definition

DSO is a measure of customer risk, providing an indication of the efficiency of a company’s collection process and its ability to analyze and anticipate customer risk.

The difference between the theoretical DSO or BPDSO (Best Possible DSO) – which measures the DSO assuming that all customers pay their invoices on time – is used to measure the potential for improvement.

DSO calul

How is DSO calculated? There are 2 main ways of calculating DSO: the accounting method and the “count back” (or “roll back”) method.

Improving DSO is essential, as trade receivables have a direct impact on WCR. Over 25% of SMEs go bankrupt due to a lack of cash, while many others survive but are hampered in their ability to innovate and grow due to a lack of adequate cash. This lack of innovation has a direct impact on their ability to differentiate themselves from the competition, and therefore to grow.

Improving DSO – the Credit Manager’s preventive role

[/vc_column_text][vc_empty_space height=”10″][vc_column_text]To improve DSO, the Credit Manager has 2 critical preventive missions: analyzing performance and anticipating customer risk. All in collaboration with the company’s various departments, including sales management.

Performance analysis:

The Credit Manager must be able to analyze the company’s performance finely and, above all, quickly. He or she must have the resources to monitor outstanding receivables, sales, DSO trends, the aged trial balance and the impact of disputes on cash flow in real time.

The objective for the credit manager is to be able to use his dashboards to identify areas of performance, but also and above all areas of underperformance. The credit manager will only be able to define the right action plan for improvement if he can identify the reasons for the gap with the BPDSO (Best Possible DSO or theoretical DSO). Is the improvement area a specific customer segment? a subsidiary? a geographical area? a branch? Is it related to late payment or non-payment?

This analysis and these pragmatic dashboards will then enable him to better spread the cash culture within the company and to better collaborate with sales management, for example in defining commercial policy on payment terms or credit limits.

This analysis will also enable the company to better anticipate its customer risk and better define its risk hedging strategy.

Customer risk analysis:

To improve their DSO, credit managers need the tools they need to understand their customer risk. To achieve this, he needs to be able to easily find all customer information in a single place, in a single credit management software package, in a simple and ergonomic way.

It must also be able to accurately analyze the evolution of each customer’s payment behavior through a scoring system.

Today, many companies offer scorings linked mainly to the company’s financial health. These scorings are essential, but companies increasingly share the view that a company in good health can be a bad payer, and a company in poor health a very good payer. Moreover, a company can be a very good payer for one supplier and a very bad one for another. It is also important to note the impact of confidential balance sheets on the ability of these companies to assess a company’s financial health.

That’s why you need to know in real time the evolution of your customer’s payment behavior in relation to their history with your company. Depending on the evolution of a customer’s payment behavior, you can automatically define the best dunning and debt collection scenario.

Improving DSO – Credit managers’ risk hedging choices

[/vc_column_text][vc_empty_space height=”10″][vc_column_text]The credit manager can choose between 2 main risk hedging methods:

Credit insurance

With credit insurance, the credit manager can transfer the risk of non-payment to a third party such as Atradius, Euler Hermes, Coface or others. This solution is extremely effective, provided it is managed precisely and efficiently, with monitoring of guarantee limits, contractual notice periods, etc. Tools exist to simplify this management. These tools act as digital personal assistants, simplifying credit insurance management and notifying the credit manager of essential tasks (for example, whether the actual outstanding amount of one of my customers exceeds the guarantee limit).

Factoring

With factoring, a company can be paid immediately for an invoice, instead of having to wait for the due date. There are many different types of factoring, including traditional full factoring, delegated factoring, factoring of the entire accounts receivable, factoring of part of the accounts receivable on an invoice basis, and different assignment methods, such as line-by-line factoring. It’s essential to take the time to analyze the type of factoring contract best suited to your business. From a technical point of view, factoring will require regular, recurring transfers of financing, which may or may not be automated, just like the technical link to the factor.[/vc_column_text][vc_empty_space height=”30″][vc_column_text el_class=”orange”]

Improving your DSO – The Credit Manager and optimizing debt collection

[/vc_column_text][vc_empty_space height=”10″][vc_column_text]After analyzing DSO performance and customer risk, and whether or not the risk is covered by credit insurance or factoring, the credit manager can concentrate on a major source of cash: invoices awaiting payment.

The customer workstation

In most companies, accounts receivable account for almost 40% of company assets. Unfortunately, in many companies, the debt collection process is still largely manual, especially in SMEs. The tasks involved are repetitive, time-consuming and resource-intensive. These tasks are perfectly eligible for automation by means of processing algorithms.

Task automation

Automatic dunning software then automates around 80% of actions, focusing employees on higher value-added tasks such as analyzing performance and customer risk, and on the really essential, high-priority collection tasks. A collection manager will always have much more impact on improving DSO by calling the 5 critical files to bring in cash than by sending 150 more or less standard emails.

These tasks must be automated in an intelligent and personalized way to protect customer relationships. The reminder for a major account must be different from the reminder for a small customer, a very large invoice from a small one, a good payer from a bad payer, and so on… This differentiation is a key factor for success, as is the ability to easily and autonomously adapt letters, emails or reminder scenarios.

This automation must also enable simple, effective collaboration between company departments (sales, advising, credit management, litigation, etc.), to increase the efficiency of late payment processing. This is known as collaborative workflow.

On average, companies that have implemented this type of approach see their cash collection increase by over 25% and their administrative tasks fall by over 50%. Late payments are very often divided by 2. The result is better cash flow, faster and with constant resources. [/vc_column_text][vc_empty_space height=”25″][vc_single_image image=”555113″ img_size=”large” alignment=”center” qode_css_animation=”element_from_fade”][vc_empty_space height=”25″][vc_column_text el_class=”orange”]

Improve your DSO – The Credit Manager and dispute management

[/vc_column_text][vc_empty_space height=”10″][vc_column_text]Around 35% of invoices over 30 days overdue are linked to a dispute. Yet many companies are still penalized by the lack of traceability of disputes, or by the lack of tools enabling them to collaborate effectively on a dispute. Here again, solutions exist, and it is essential for a company to be able to ensure proper traceability and collaboration around these disputes.

3 major benefits: faster processing of claims and therefore faster cash flow, improved customer satisfaction and better internal collaboration.[/vc_column_text][vc_empty_space height=”50″][vc_single_image image=”6704″ img_size=”full” alignment=”center” qode_css_animation=”element_from_fade”][vc_separator type=”normal” color=”#e3e3e3″ thickness=”1″ up=”35″ down=”25″][vc_column_text]
