Production/Stable dhongu/deltatech

Sale Add Extra Line - Point of Sale Extension

The deltatech_sale_add_extra_line_pos module is an Odoo addon that extends the Point of Sale (POS) functionality to automatically add extra product lines to POS orders based on configured products. This module is a specialized extension of the deltatech_sale_add_extra_line module, specifically designed for the Point of Sale system.

Features

  • Real-time POS Integration: Seamlessly integrates automatic extra line addition directly into the Point of Sale interface
  • Client-side Processing: Handles extra product addition on the client side for immediate visual feedback
  • Dynamic Quantity Calculation: Automatically calculates and updates extra product quantities based on the main product quantities in the POS cart
  • Product Configuration: Allows configuration of extra products and quantity multipliers directly in the product template
  • Automatic Line Consolidation: Intelligently consolidates multiple extra product lines into a single line with the correct total quantity
  • Real-time Updates: Updates extra product quantities instantly when main product quantities are modified in the POS cart

How It Works

Product Configuration

In the product template, you can configure:

  • Extra Product: The product that should be automatically added when the main product is sold
  • Extra Quantity Multiplier: A multiplier to calculate how much of the extra product should be added (e.g., 0.1 means 10% of the main product quantity)

POS Workflow

  1. Adding Products: When a cashier adds a product with extra product configuration to the POS cart, the system automatically adds the configured extra product as a separate line
  2. Quantity Adjustment: When the quantity of the main product is modified, the extra product quantity is automatically recalculated based on:
    • All instances of products that reference the same extra product
    • The quantity multiplier configured for each product
    • The formula: Extra Qty = Σ(Main Product Qty × Extra Qty Multiplier)
  3. Line Consolidation: If an extra product is referenced by multiple products in the cart, the module consolidates them into a single line with the aggregated quantity
  4. Session Processing: When the POS session is closed, the extra product information is properly transferred to the backend for order processing

Use Cases

This module is particularly useful for retail and hospitality businesses that need to:

  • Environmental Fees: Automatically add environmental or recycling fees based on product types
  • Bag Charges: Add shopping bag charges based on the number or volume of products purchased
  • Service Charges: Include service or handling fees for certain product categories
  • Packaging Materials: Automatically account for packaging materials used per product
  • Deposit Fees: Add deposit charges for returnable containers or bottles
  • Transaction Fees: Include payment processing or transaction fees

Technical Implementation

The module extends the Point of Sale system through:

  • JavaScript Patches: Extends POS order and order line models using Odoo’s patch mechanism
  • Client-side Logic: Implements automatic extra line addition and quantity calculation in the POS interface
  • Backend Integration: Ensures proper synchronization of extra product information between frontend and backend
  • Product Template Extension: Adds extra product fields to the product template model
  • Session Handling: Properly loads extra product configuration data when POS sessions are opened

Benefits

  • Improved Accuracy: Eliminates manual errors in adding fees or related products
  • Faster Checkout: Reduces time spent manually adding extra items
  • Consistency: Ensures uniform application of fees and charges across all transactions
  • Transparency: Customers can clearly see extra charges itemized on their receipt
  • Compliance: Helps meet regulatory requirements for separate fee disclosure
  • Efficiency: Cashiers can focus on customer service rather than remembering to add extra items

Dependencies

This module depends on:

  • deltatech_sale_add_extra_line - The base module for extra line functionality
  • point_of_sale - Odoo’s Point of Sale module

Integration

The module works seamlessly with Odoo’s standard POS features and can be combined with other POS extensions for enhanced functionality.
