1. Introduction

Late payments are a frequent challenge for businesses of all sizes. They disrupt cash flow, increase administrative overhead, and may even strain client relationships. One effective way to reduce late payments is by introducing late fees. Dolibarr ERP & CRM includes options for managing and applying penalties for overdue invoices. This guide provides a comprehensive look at how to configure, implement, and manage late payment fees in Dolibarr effectively.

2. Understanding the Concept of Late Fees

Late fees are additional charges applied to an invoice when a client fails to pay by the due date. They are typically calculated based on a fixed amount, a percentage of the overdue amount, or a combination of both.

3. Business Benefits of Charging Late Payment Penalties

  • Encourages timely payments

  • Compensates for the cost of capital delay

  • Establishes financial discipline

  • Reduces the need for repeated follow-ups

4. Legal Considerations Before Applying Late Fees

Before activating late fees:

  • Verify your country or regional laws regarding late payment interest

  • Include terms in contracts and general terms of sale

  • Inform clients explicitly through invoice notes

Dolibarr allows custom fields and notes to communicate these terms.

5. How Dolibarr Handles Late Payment Management

While Dolibarr does not enable automatic late fees by default, it offers:

  • Manual calculation and entry of late charges

  • Custom extrafields on invoices

  • Integration with the Dunning/Reminders module

  • Customization via modules or scripts

6. Preparing Your Dolibarr Setup for Late Fees

Modules to activate:

  • Invoices

  • Bank/Cash

  • Dunning Reminders (optional but recommended)

  • Custom Fields (if needed for automated logic)

Admin access is typically required to make these configuration changes.

7. Enabling Late Fee Features in Dolibarr

There is no dedicated checkbox for "late fees" in the core settings, but the process involves:

  • Creating an invoice line for penalty charges

  • Automating detection of overdue invoices

  • Optionally creating a service product called "Late Fee"

8. Setting Default Late Fee Rules

Define a policy such as:

  • A flat fee (e.g., 25 EUR per overdue invoice)

  • A percentage (e.g., 2% of overdue balance per month)

  • A grace period (e.g., 7 days after the due date)

Store this in a template note field for transparency.

9. Customizing Late Fees Per Invoice

Use invoice extrafields or manual additions to add:

  • Late fee type

  • Percentage

  • Applicable date

This flexibility allows case-by-case penalties.

10. Automating the Application of Late Charges

Automation options include:

  • Manual review scripts to scan overdue invoices

  • Using cron jobs with custom PHP scripts

  • Third-party modules (some Dolistore plugins offer this feature)

Administrators can develop or install a module to auto-generate penalty lines.

11. Integrating Late Fees with Payment Reminders

Use the Reminders module to:

  • Send emails on due date and X days later

  • Include wording about late fees applied after X days

  • Add links to updated invoices with penalties

Templates can dynamically include amounts using placeholder tags.

12. Displaying Penalties Clearly on Invoice Documents

Modify the PDF template:

  • Add a separate line for late fees

  • Include explanation in the notes section

  • If using extrafields, pull those into the PDF via template override

This ensures legal compliance and transparency.

13. Managing Exemptions and Special Cases

Dolibarr allows manual control over:

  • Whether to apply penalties on specific invoices

  • Adjusting the fee amount to accommodate loyal customers

  • Removing fees if a delay is justified

Use internal comments or tags to log reasoning.

14. Tracking and Reporting Late Fee Revenue

Use the Reporting module to:

  • Track invoices with added late fees

  • Create reports filtered by service/product = "Late Fee"

  • Export penalty earnings for accounting

This helps quantify the impact of your policy.

15. Integrating with Accounting and Reconciliation Modules

Once a penalty is paid:

  • The line item reflects in your income reports

  • Reconciliation is performed via the Bank module

  • Accounting modules log the late fee in the appropriate revenue account

Ensure chart of accounts supports a "Penalty Income" account.

16. Dealing with Disputes and Adjustments

To resolve disputes:

  • Keep documentation of the due date and reminder timeline

  • Show invoice PDF with penalty clause

  • Offer partial waivers if necessary

Record all changes via the "Change Log" or manual comment history.

17. Best Practices for Transparent Client Communication

  • Mention late fee policy in every invoice footer

  • Communicate verbally and in writing at the contract stage

  • Be consistent but flexible in exceptional situations

Consistency builds trust and sets expectations.

18. Case Study: Applying Late Fees in a Subscription Business

A web hosting company using Dolibarr:

  • Created a recurring invoice template

  • Added a "Late Fee" product with 5% surcharge

  • Used cron job + notification email after 10 days overdue

  • Collected 92% of payments on time within three months

Their combination of automation and communication reduced late payments dramatically.

19. Common Mistakes and How to Avoid Them

  • Applying penalties without prior notice

  • Not validating invoices before due dates

  • Charging fees incorrectly (wrong calculation base)

  • Forgetting to remove penalties if payment is settled

Review each penalty application for accuracy.

20. Conclusion and Strategic Recommendations

Dolibarr supports late fee management through a flexible, modular system. Although not fully automated out of the box, it provides all the tools necessary for a robust late fee strategy. Businesses that clearly define, communicate, and enforce a consistent late payment policy will see improved cash flow and reduced receivable turnover time.

Combining invoice management, reminder automation, and transparent penalty application turns Dolibarr into a powerful tool for financial discipline. For full automation, consider module development or third-party extensions tailored to your policy structure.
