Customer dunning and collection: best practices for improving collection and reducing payment times

Customer follow-up and collection
Contents

In short: Effective customer collection begins before the due date, follows a defined process, and is tailored to each customer. When automated, it saves time and reduces payment delays. The 5 best practices:

  • follow up before the due date;
  • Follow a follow-up procedure (email, phone call, or letter if necessary);
  • automate follow-ups;
  • adjust your tone to the situation;
  • track payment commitments.
What is a customer reminder?

Customer collection refers to all actions taken to obtain payment of an invoice that is past due or overdue.
As such, it is a cornerstone of credit management and a key tool for reducing DSO and improve cash flow.

It’s not just for use when there’s a delay—it also allows you to politely notify the customer of an upcoming due date. It can be sent via email, text message, phone call, letter, or certified mail, depending on the importance of the follow-up and your relationship with the customer. The standard practice is to start with an email and follow up, if necessary, with a registered letter. In the event of a delay, the reminder also opens a dialogue to understand the reason for the delay.

Why customer reminders are strategic

An effective customer reminder has a number of benefits. It allows :

  • speed up collections
  • reduce overdue payments
  • secure cash
  • improve customer relations

On the other hand, a poorly structured customer reminder has a number of consequences. These include:

Common mistakes in customer reminders

1. Relaunch too late

Waiting several weeks after the due date greatly reduces the chances of payment. In fact, the longer the delay, the greater the risk of non-payment.

2. Irregular relaunching

What’s more, an unstructured customer reminder is ineffective.

3. Lack of traceability

Without a history, it’s difficult to keep track of what’s been done. As a result, management becomes less effective.

4. Lack of customization

On the other hand, a generic customer reminder is less effective.

5. Use of unsuitable tools

Finally, Excel and conventional tools limit the performance of customer collection. As a result, teams lose efficiency.

Best practices for customer reminders

1. Relaunch before the deadline

In this way, pre-delivery anticipates delays and improves collections.

2. Structuring a recovery scenario

An effective customer relaunch is based on a defined plan. For example, it may include :

  • email reminder
  • phone call
  • mail if necessary
3. Automate customer reminders

Collection software offers a number of advantages. It enables you to:

  • automatically trigger reminders
  • standardize messages
  • save time

What’s more, it improves stock consistency.

4. Adapt tone and message

The tone must evolve according to the situation. It can be:

  • preventive
  • farm
  • more direct in the event of long delays
5. Track payment promises

Lastly, a promise to pay must be strictly adhered to. Otherwise, the risk of delay persists.
