# 👥 Customer Analytics - Data Logic Documentation
|
||||
|
||||
**Last Updated:** Nov 4, 2025 12:48 AM (GMT+7)
|
||||
|
||||

|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
This document defines the business logic for Customer Analytics metrics, clarifying which data is **period-based** vs **store-level**.
|
||||
|
||||
---
|
||||
|
||||
## 📊 Stat Cards Layout
|
||||
|
||||
### Row 1: Period-Based Metrics (with comparisons)
|
||||
```
|
||||
[New Customers] [Retention Rate] [Avg Orders/Customer] [Avg Lifetime Value]
|
||||
```
|
||||
|
||||
### Row 2: Store-Level + Segment Data
|
||||
```
|
||||
[Total Customers] [Returning] [VIP Customers] [At Risk]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📈 Metric Definitions
|
||||
|
||||
### 1. **New Customers** ✅ Period-Based
|
||||
- **Definition:** Number of customers who made their first purchase in the selected period
|
||||
- **Affected by Period:** YES
|
||||
- **Has Comparison:** YES (vs previous period)
|
||||
- **Logic:**
|
||||
```typescript
|
||||
new_customers = sum(acquisition_chart[period].new_customers)
|
||||
change = ((current - previous) / previous) × 100
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. **Retention Rate** ✅ Period-Based
|
||||
- **Definition:** Percentage of customers who returned in the selected period
|
||||
- **Affected by Period:** YES
|
||||
- **Has Comparison:** YES (vs previous period)
|
||||
- **Logic:**
|
||||
```typescript
|
||||
retention_rate = (returning_customers / total_in_period) × 100
|
||||
total_in_period = new_customers + returning_customers
|
||||
```
|
||||
- **Previous Implementation:** ❌ Was store-level (global retention)
|
||||
- **Fixed:** ✅ Now calculates from period data
|
||||
|
||||
---
|
||||
|
||||
### 3. **Avg Orders/Customer** ❌ Store-Level
|
||||
- **Definition:** Average number of orders per customer (all-time)
|
||||
- **Affected by Period:** NO
|
||||
- **Has Comparison:** NO
|
||||
- **Logic:**
|
||||
```typescript
|
||||
avg_orders_per_customer = total_orders / total_customers
|
||||
```
|
||||
- **Rationale:** This is a ratio metric representing customer behavior patterns, not a time-based sum
|
||||
|
||||
---
|
||||
|
||||
### 4. **Avg Lifetime Value** ❌ Store-Level
|
||||
- **Definition:** Average total revenue generated by a customer over their entire lifetime
|
||||
- **Affected by Period:** NO
|
||||
- **Has Comparison:** NO
|
||||
- **Logic:**
|
||||
```typescript
|
||||
avg_ltv = total_revenue_all_time / total_customers
|
||||
```
|
||||
- **Previous Implementation:** ❌ Was scaled by period factor
|
||||
- **Fixed:** ✅ Now always shows store-level LTV
|
||||
- **Rationale:** LTV is cumulative by definition - scaling it by period makes no business sense
|
||||
|
||||
---
|
||||
|
||||
### 5. **Total Customers** ❌ Store-Level
|
||||
- **Definition:** Total number of customers who have ever placed an order
|
||||
- **Affected by Period:** NO
|
||||
- **Has Comparison:** NO
|
||||
- **Display:** Shows "All-time total" subtitle
|
||||
- **Logic:**
|
||||
```typescript
|
||||
total_customers = data.overview.total_customers
|
||||
```
|
||||
- **Previous Implementation:** ❌ Was calculated from period data
|
||||
- **Fixed:** ✅ Now shows all-time total
|
||||
- **Rationale:** Represents store's total customer base, not acquisitions in period
|
||||
|
||||
---
|
||||
|
||||
### 6. **Returning Customers** ✅ Period-Based
|
||||
- **Definition:** Number of existing customers who made repeat purchases in the selected period
|
||||
- **Affected by Period:** YES
|
||||
- **Has Comparison:** NO (shown as segment card)
|
||||
- **Display:** Shows "In selected period" subtitle
|
||||
- **Logic:**
|
||||
```typescript
|
||||
returning_customers = sum(acquisition_chart[period].returning_customers)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 7. **VIP Customers** ❌ Store-Level
|
||||
- **Definition:** Customers who qualify as VIP based on lifetime criteria
|
||||
- **Qualification:** 10+ orders OR lifetime value > Rp5,000,000
|
||||
- **Affected by Period:** NO
|
||||
- **Has Comparison:** NO
|
||||
- **Logic:**
|
||||
```typescript
|
||||
vip_customers = data.segments.vip
|
||||
```
|
||||
- **Rationale:** VIP status is based on cumulative lifetime behavior, not period activity
|
||||
|
||||
---
|
||||
|
||||
### 8. **At Risk Customers** ❌ Store-Level
|
||||
- **Definition:** Customers with no orders in the last 90 days
|
||||
- **Affected by Period:** NO
|
||||
- **Has Comparison:** NO
|
||||
- **Logic:**
|
||||
```typescript
|
||||
at_risk = data.segments.at_risk
|
||||
```
|
||||
- **Rationale:** At-risk status is a current state classification, not a time-based metric
|
||||
|
||||
---
|
||||
|
||||
## 📊 Charts & Tables
|
||||
|
||||
### Customer Acquisition Chart ✅ Period-Based
|
||||
- **Data:** New vs Returning customers over time
|
||||
- **Filtered by Period:** YES
|
||||
- **Logic:**
|
||||
```typescript
|
||||
chartData = period === 'all'
|
||||
? data.acquisition_chart
|
||||
: data.acquisition_chart.slice(-parseInt(period))
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Lifetime Value Distribution ❌ Store-Level
|
||||
- **Data:** Distribution of customers across LTV ranges
|
||||
- **Filtered by Period:** NO
|
||||
- **Logic:**
|
||||
```typescript
|
||||
ltv_distribution = data.ltv_distribution // Always all-time
|
||||
```
|
||||
- **Rationale:** LTV is cumulative, distribution shows overall customer value spread
|
||||
|
||||
---
|
||||
|
||||
### Top Customers Table ✅ Period-Based
|
||||
- **Data:** Customers with highest spending in selected period
|
||||
- **Filtered by Period:** YES
|
||||
- **Logic:**
|
||||
```typescript
|
||||
filteredTopCustomers = period === 'all'
|
||||
? data.top_customers
|
||||
: data.top_customers.map(c => ({
|
||||
...c,
|
||||
total_spent: c.total_spent * (period / 30),
|
||||
orders: c.orders * (period / 30)
|
||||
}))
|
||||
```
|
||||
- **Previous Implementation:** ❌ Was always all-time
|
||||
- **Fixed:** ✅ Now respects period selection
|
||||
- **Note:** Uses global period selector (no individual toggle needed)
|
||||
|
||||
---
|
||||
|
||||
## 🔄 Comparison Logic
|
||||
|
||||
### When Comparisons Are Shown:
|
||||
- Period is **7, 14, or 30 days**
|
||||
- Metric is **period-based**
|
||||
- Compares current period vs previous period of same length
|
||||
|
||||
### When Comparisons Are Hidden:
|
||||
- Period is **"All Time"** (no previous period to compare)
|
||||
- Metric is **store-level** (not time-based)
|
||||

|
||||
|
||||
## ✅ Changes Made
|
||||
|
||||
### 1. **Total Customers**
|
||||
- **Before:** Calculated from period data (new + returning)
|
||||
- **After:** Shows all-time total from `data.overview.total_customers`
|
||||
- **Reason:** Represents store's customer base, not period acquisitions
|
||||
|
||||
### 2. **Avg Lifetime Value**
|
||||
- **Before:** Scaled by period factor `avg_ltv * (period / 30)`
|
||||
- **After:** Always shows store-level `data.overview.avg_ltv`
|
||||
- **Reason:** LTV is cumulative by definition, cannot be period-based
|
||||
|
||||
### 3. **Retention Rate**
|
||||
- **Before:** Store-level `data.overview.retention_rate`
|
||||
- **After:** Calculated from period data `(returning / total_in_period) × 100`
|
||||
- **Reason:** More useful to see retention in specific periods
|
||||
|
||||
### 4. **Top Customers Table**
|
||||
- **Before:** Always showed all-time data
|
||||
- **After:** Filtered by selected period
|
||||
- **Reason:** Useful to see top spenders in specific timeframes
|
||||
|
||||
### 5. **Card Layout Reordered**
|
||||
- **Row 1:** Period-based metrics with comparisons
|
||||
- **Row 2:** Store-level + segment data
|
||||
- **Reason:** Better visual grouping and user understanding
|
||||

## 🎯 Business Value
|
||||
|
||||
### Period-Based Metrics Answer:
|
||||
- "How many new customers did we acquire this week?"
|
||||
- "What's our retention rate for the last 30 days?"
|
||||
- "Who are our top spenders this month?"
|
||||
|
||||
### Store-Level Metrics Answer:
|
||||
- "How many total customers do we have?"
|
||||
- "What's the average lifetime value of our customers?"
|
||||
- "How many VIP customers do we have?"
|
||||
- "How many customers are at risk of churning?"
|
||||
|

|
||||
|
||||
## 🔮 Future Enhancements
|
||||
|
||||
### Custom Date Range (Planned)
|
||||
When custom date range is implemented:
|
||||
- Period-based metrics will calculate from custom range
|
||||
- Store-level metrics remain unchanged
|
||||
- Comparisons will be hidden (no "previous custom range")
|
||||
|
||||
### Real API Integration
|
||||
Current implementation uses dummy data with period scaling. Real API will:
|
||||
- Fetch period-specific data from backend
|
||||
- Calculate metrics server-side
|
||||
- Return proper comparison data
|
||||
|
