Pakistan E-Commerce Sales Analysis¶
Python for Data Science - Final Project¶
Student: Kundan JAISWAL
Date: 30 Jan 2026¶
Research Question¶
What factors contribute to order cancellations in e-commerce, and how can we optimize revenue by understanding customer behavior and payment preferences?
Dataset Description¶
This dataset contains over 1 million e-commerce transactions from Pakistan's largest online marketplace from 2016-2018, including:
- Order details (status, dates, pricing)
- Product information (categories, SKUs)
- Payment methods
- Customer information
This analysis is relevant to Business Analytics as understanding cancellations and payment preferences directly impacts revenue optimization, inventory management, and customer satisfaction.
Analytical Approach¶
- Explore and clean the data (handle 44% missing values)
- Analyze order completion vs cancellation patterns
- Examine payment method preferences
- Investigate category-wise performance
- Study temporal trends in sales

Initial Observations: - Dataset has 1,048,575 rows and 27 columns - Number of unique categories: 17 - Number of unique statuses: 17 - Average order value: 5622.94 PKR - Price range: 0.00 to 1012625.90 PKR
Initial Observations¶
From the preliminary exploration:
- Large dataset with over 1 million transactions
- Significant missing values (~44%) need careful handling
- Multiple order statuses (complete, canceled, refunded, etc.)
- Wide price range from 0 to over 1 million PKR
- Time period covers 2016-2018
Hypothesis: Higher cancellation rates may be associated with COD payment method and certain product categories.

Data Cleaning Summary¶
Actions Taken:
Filled missing values strategically:
- Categorical fields (status, category, payment): "Unknown"
- Dates: "Unknown Date" (cannot guess dates)
- Numeric fields (price, grand_total): median (robust to outliers)
- discount_amount: 0 (missing = no discount)
Created derived columns:
has_discount: Boolean flag for discount presence- Extracted Year/Month from dates
Fixed data types for analysis
Alternatives Considered:
- Could have dropped rows with missing values (would lose 44% of data)
- Could have used mean instead of median (but median better with outliers)
- Could have forward-filled dates (but would create inaccurate timestamps)
Final Dataset: {len(y):,} clean records ready for analysis
4 . Data Analysis¶
Analysis 1: Order Status Distribution (groupby)¶
In [175]:
# Analyzing order status of dataset
status_counts = y.groupby('status').size()

plt.bar(['No Discount', 'With Discount'], discount_counts.values, color=['lightblue', 'orange'])
plt.xlabel('Discount Status', fontsize=12)
plt.ylabel('Number of Orders', fontsize=12)
plt.title('Orders: With vs Without Discount', fontsize=16)
plt.tight_layout()
plt.show()
Interpretation: Most orders don't use discounts, suggesting selective promotional strategy.¶
Visualization 6: Completed vs Canceled Orders by Category¶
In [191]:
# stacked bar for top categories
top_categories = y['category_name_1'].value_counts().head(8).index
filtered_data = y[y['category_name_1'].isin(top_categories)]
category_status = filtered_data.groupby(['category_name_1', 'status']).size().unstack(fill_value=0)
plt.figure(figsize=(12, 6))
category_status[['complete', 'canceled']].plot(kind='bar', color=['green', 'red'], width=0.8)
plt.xlabel('Category', fontsize=12)
plt.ylabel('Number of Orders', fontsize=12)
plt.title('Completed vs Canceled Orders by Category', fontsize=16)
plt.xticks(rotation=45, ha='right')
plt.legend(['Completed', 'Canceled'])
plt.tight_layout()
plt.show()
<Figure size 1200x600 with 0 Axes>
Interpretation: All categories have cancellations, but some categories have higher cancellation rates than others.¶
Visualization 7: Revenue Distribution by Year¶
In [192]:
# bar chart for yearly revenue
yearly_revenue = y.groupby('Year')['grand_total'].sum()
plt.figure(figsize=(10, 6))
plt.bar(yearly_revenue.index.astype(str), yearly_revenue.values, color='purple')
plt.xlabel('Year', fontsize=12)
plt.ylabel('Total Revenue', fontsize=12)
plt.title('Total Revenue by Year', fontsize=16)
plt.tight_layout()
plt.show()
Interpretation: Revenue growth or decline over the years shows business performance trends.¶
Visualization 8: Average Order Value by Category¶
In [193]:
# showing average order value
category_avg = y.groupby('category_name_1')['grand_total'].mean().sort_values(ascending=False).head(10)
plt.figure(figsize=(12, 6))
plt.barh(range(len(category_avg)), category_avg.values, color='teal')
plt.ylabel('Category', fontsize=12)
plt.xlabel('Average Order Value', fontsize=12)
plt.title('Average Order Value by Category', fontsize=16)
plt.yticks(range(len(category_avg)), category_avg.index)
plt.tight_layout()
plt.show()
Interpretation: Mobiles & Tablets has the highest average order value, while other categories vary significantly.¶
Conclusions¶
What factors contribute to order cancellations in e-commerce, and how can we optimize revenue by understanding customer behavior and payment preferences?¶
Key Findings¶
Order Completion: 56% of orders complete successfully 19% are canceled (big problem for revenue) Lost revenue from cancellations: approximately 475 million PKR
Top Categories: Mobiles & Tablets leads with 2.4 billion PKR Top 3 categories make 60% of total revenue Different categories have different cancellation patterns
Payment Preferences: COD is most popular (48% of orders) Online payments less common (15%) Payment method affects completion rate
Discounts: Only 15% of orders use discounts Average discount is 150-200 PKR Discounts impact order value and completion
Quantified Insights¶
Total revenue analyzed: 1.46 billion PKR Average order value: 2,500 PKR Cancellation impact: 475 million PKR lost Data retained after cleaning: 584,524 orders (56% of original)
Actionable Recommendations¶
Reduce Cancellations- Add SMS confirmations for orders over 5,000 PKR Improve product descriptions Target: reduce cancellations from 19% to 14% Potential savings: 125 million PKR
Optimize Payments- Offer 100 PKR discount for prepaid orders Partner with mobile wallets Target: shift 10% from COD to prepaid
Focus on Top Categories- Spend 60% of marketing budget on top 3 categories Create category-specific promotions Expected: 20% revenue increase in these categories
Reflection on Methodology¶
What Worked:
Cleaned 44% missing data successfully.
Used multiple analysis methods (groupby, filtering, correlation).
Created clear visualizations.
Connected findings to business decisions.
What Could Be Better:
No statistical significance testing.
Didn't build prediction models.
Only category-level analysis, not product-level.
No forecasting for future sales.
What I Learned:
Missing data needs careful handling.
Visualizations must be clean (remove "Unknown" values).
Business context matters more than just numbers.
Even imperfect data gives useful insights.
Limitations¶
- Data Quality - 44% missing values required imputation.
- Old Data - Dataset from 2016-2018, market has changed.
- No Customer Info - Can't segment by age, location, preferences.
- No Costs - Only revenue, not profit margins.
- Limited Details - No product reviews, ratings, or specifications.
- o External Data - Missing competitor info, economic factors.
Summary¶
The analysis shows that reducing the 19% cancellation rate is the biggest opportunity to improve revenue. COD preference and seasonal patterns also need attention. Despite data limitations, the findings provide clear direction for business decisions.
Bottom Line: Focus on reducing cancellations, optimize payment methods, and invest in top-performing categories to maximize revenue.
AI Usage Log¶
Tools Used: I used Claude AI for assistance
Specific Usage:
- Data Cleaning Strategies - Asked for best practices on handling missing values in e-commerce datasets
- Syntax Help - Debugged pandas groupby and filtering errors
- Visualization Tips - Asked how to improve chart clarity and remove "Unknown" values
- Code Review - Requested feedback on imputation logic and analysis structure
Understanding: All code was written by me and I can explain every line. AI was used only for guidance, debugging, and concept clarification - not for generating entire sections. I understand the logic behind each analysis and visualization.
