Overview

The POS Discount Reason module is a comprehensive solution for tracking and managing discounts in Odoo's Point of Sale system. It ensures that every discount applied requires a reason, providing better accountability and audit trails for restaurant and retail operations.

This module is specifically designed for Dar Al Mahashi Restaurant to maintain detailed records of all discount transactions, helping with financial reporting and compliance.

Key Features

Mandatory Discount Reasons: Requires cashiers to provide a reason when applying discounts or negative prices
Product-Level Control: Mark products as discountable or non-discountable
Real-time Validation: Prompts appear automatically when discounts are applied during checkout
Comprehensive Reporting: View discount reasons in sales detail reports
Total Discountable Calculation: Automatically computes total discountable amounts per order
Negative Price Handling: Special handling for negative price adjustments with reason tracking

How It Works

Product Configuration: Products can be marked as "Discountable" in the product form

Applying Discounts: When a cashier applies a discount to an order line in the POS interface

Reason Prompt: A popup automatically appears asking for the discount reason

Validation: The discount is only applied if a reason is provided; otherwise, the discount is removed

Checkout Check: Before payment, the system verifies all discounted items have reasons

Reporting: Discount reasons are visible in daily sales reports and order details

Screenshots & Features

Discount Reason in Order Line

When applying a discount to an order line in the POS interface, a popup appears requiring the cashier to enter a reason for the discount. This ensures all discounts are properly documented and tracked.

POS Discount Application

The discount reason feature is seamlessly integrated into the Point of Sale interface. Cashiers can apply discounts with mandatory reason tracking directly from the POS screen.

Sales Details Wizard

The sales details wizard includes an option to show discount details in reports. Administrators can enable "Show Discount Details" to include discount reason information in sales reports.

Generate Discount Report

Generate comprehensive sales reports with discount details. Select the date range, POS configuration, and enable the discount details option to view all discount reasons in the report.

Discount Sales Report

The sales detail report displays all discount reasons for each transaction, including order reference, date, employee, customer, and the reason for each discount applied. This provides complete audit trails for financial compliance.
