Interest on Overdue Invoices

seprator

Interest on Overdue Invoices Odoo app helps businesses calculate and apply interest charges on overdue customer invoices directly within Odoo. This module allows companies to manage late payment interest in a controlled and transparent way while keeping accounting records accurate.

The app supports configurable interest rules, allowing interest to be calculated as a percentage or flat amount. Businesses can define grace periods to allow delayed payments without penalties and apply penalty charges as one-time fees when required. All interest calculations are recorded with a complete calculation history for audit and reference.

With per-customer interest configuration, multi-company support, and full integration with Odoo Accounting, this module gives users full control over late payment policies. It ensures interest entries are posted safely, avoids duplicate charges, and maintains proper financial tracking.

This Overdue Invoice Interest Management Odoo app is ideal for companies that want to reduce late payments, enforce payment discipline, and manage overdue invoices efficiently without affecting customer relationships.

General Settings

Start by configuring the global settings for your company. Here you can enable the 'Interest on Overdue' feature, define the default interest rule that applies to all customers unless overridden, and map the specific Income Account and Accounting Journals where these interest charges will be posted. This ensures a seamless integration with your chart of accounts.

Company Settings

Customer Configuration

Tailor the interest policy for specific clients. On the Customer Contact form, you can override the global defaults. Use this to explicitly disable interest for VIP clients, assign a specific stricter or more lenient interest rule, or provide additional grace period days to specific customers to maintain good relationships.


Customer Settings Override

Customer Form

Interest Rules

Define how interest is calculated. You can manage all your rules from a central list and simple forms. The system supports both Flat Fee and Percentage-based calculations to match your business needs.


Rule Overview

Get a clear overview of all your interest policies in one place. The Interest Rules menu lists all defined rules—whether flat fee or percentage-based—allowing you to manage and update your penalty structures easily.

Rules List

Flat Fee Rule

Configure a Flat Fee rule to charge a fixed penalty amount regardless of the invoice value. This is ideal for administrative late fees. In this example, a fixed amount of 100 is configured to be charged per period.

Flat Fee Rule

Percentage Rule

Set up a Percentage-based rule to charge interest proportional to the overdue amount. For instance, you can define a 1.5% monthly interest rate. The system will automatically calculate the exact interest based on the open balance and the number of days the invoice is overdue.

Percentage Rule

Full Process Flow

The module provides a comprehensive workflow from detecting overdue invoices to generating the final interest debit note. Below are the workflows for both Flat Fee and Percentage scenarios.


SCENARIO 1: FLAT FEE APPLICATION

1. Overdue Detection

The system automatically identifies overdue invoices. Here, an invoice is shown that is 1 day overdue, triggering the eligibility for interest application.

Overdue Invoice

2. Trigger Calculation

A dedicated 'Preview Interest' button appears on overdue invoices. Clicking this gives you a real-time preview of the potential charges without immediately posting them.

Preview Button

3. Calculation Preview

Review the calculation logic in detail. The wizard shows exactly how the interest was computed—displaying the overdue days and the resulting penalty amount—ensuring transparency before you proceed.

4. Apply Interest

Once verified, use the 'Apply Interest' action link to confirm the charge. This action initiates the creation of the accounting entry.

5. Generated Invoice (Draft)

A new customer invoice (Debit Note) is generated for the interest amount. This document is linked to the original overdue invoice and awaits your final confirmation to be posted.

6. Smart Button Access

Navigate easily between documents. A smart button is added to the original invoice, providing a direct link to all related interest charges, keeping your records organized.

7. Final Interest Record

View the specific interest record generated. This document validates the calculation and serves as the official record of the penalty applied.

SCENARIO 2: PERCENTAGE BASED CALCULATION

1. Percentage Rule Setup

Here is a Percentage Rule configuration, typically used for compounding interest or standard late payment fees based on the outstanding balance.

2. Invoice Analysis

An invoice subject to the percentage rule. The system monitors the due date and the outstanding amount to prepare for calculation.

3. Calculation Details

4. Resulting Interest Invoice
