by

Summary

The problem at hand is to implement a discount system that offers an extra 5% discount for orders paid via online payment (prepayment) compared to COD (Cash on Delivery) payment. This requires integrating a conditional discount feature into an existing e-commerce platform, such as Shopify.

Root Cause

The root cause of the issue is the lack of a built-in feature in Shopify to differentiate between online payment and COD payment methods for discount applications. Key causes include:

  • Limited native functionality for conditional discounts based on payment methods
  • Insufficient customization options in standard Shopify plans
  • Need for third-party apps or custom coding to achieve the desired functionality

Why This Happens in Real Systems

This issue occurs in real systems due to:

  • E-commerce platform limitations: Many platforms, including Shopify, have limited built-in features for conditional discounts based on payment methods.
  • Customization requirements: Businesses often require unique discount structures that are not supported by standard platform features.
  • Integration complexities: Third-party apps or custom coding may be necessary to bridge the functionality gap, which can be challenging to implement and maintain.

Real-World Impact

The real-world impact of not having this feature includes:

  • Lost sales: Customers may be deterred by higher prices for online payment methods.
  • Reduced revenue: Businesses may miss out on potential sales and revenue due to the lack of a competitive pricing strategy.
  • Customer dissatisfaction: Customers may feel that the pricing is unfair or not transparent, leading to negative reviews and word-of-mouth.

Example or Code (if necessary and relevant)

# Example of a conditional discount function in Python
def apply_discount(order_total, payment_method):
    if payment_method == "online":
        discount_percentage = 0.05
        discount_amount = order_total * discount_percentage
        return order_total - discount_amount
    else:
        return order_total

How Senior Engineers Fix It

Senior engineers fix this issue by:

  • Evaluating third-party apps: Researching and testing apps like Releasit COD Form & Upsells to determine their suitability.
  • Custom coding: Developing custom solutions using Shopify’s API or other programming languages to integrate the desired functionality.
  • Platform customization: Utilizing Shopify’s theme settings and liquid templating to create a tailored solution.

Why Juniors Miss It

Junior engineers may miss this issue due to:

  • Lack of experience: Limited familiarity with e-commerce platforms and their limitations.
  • Insufficient knowledge: Not understanding the conditional discount requirements and how to implement them.
  • Overreliance on built-in features: Failing to consider custom coding or third-party apps as potential solutions.
