# Cost Tracking System Gameplan - Issue #88
**Date**: 2025-10-04
**Status**: DESIGN PHASE
**Priority**: MEDIUM
**Estimated Effort**: 3-4 weeks development
## 🎯 Executive Summary
Implement a comprehensive cost tracking and allocation system that:
- **Tracks operational costs** (monthly subscriptions, one-time expenses)
- **Allocates costs to active issues** in each calculation period
- **Maintains financial audit trail** with transaction history
- **Calculates issue valuations** based on cost allocation
- **Handles historical costs** through Loss Carried Forward mechanism
## 📋 Requirements Analysis
### **Business Model**
```yaml
Cost Sources:
- Monthly Recurring: Server instances, SaaS subscriptions, domains
- One-Time Costs: Setup fees, equipment, licenses
Cost Allocation:
- Target: Active issues (new + modified) in calculation period
- Method: Equal distribution across active issues
- Historical: Unallocated costs carry forward to next period
Financial Tracking:
- Ledger-based accounting with double-entry principles
- Transaction audit trail for all cost movements
- Period-based calculations and reporting
```
### **Example Cost Items (from issue description)**
- **Hosteurope server**: €10/month
- **Bubble.io plan**: €32/month
- **Coulomb.social domain**: €5/month
- **Claude Code plan**: €20/month
- **Gemini plan**: €20/month
- **Total monthly**: €87/month
## 🏗️ Technical Architecture
### **Database Schema**
```sql

## 💰 **Cost Allocation Algorithm**
### **Monthly Calculation Process**
```python
def calculate_monthly_allocation(period_start, period_end):
"""
1. Identify all costs for the period
2. Calculate total cost burden
3. Identify active issues
4. Distribute costs equally
5. Handle loss carried forward
6. Create audit transactions
"""
# Step 1: Gather costs
monthly_costs = get_monthly_costs_for_period(period_start, period_end)
one_time_costs = get_one_time_costs_for_period(period_start, period_end)
carried_forward = get_loss_carried_forward(previous_period)
total_costs = monthly_costs + one_time_costs + carried_forward
# Step 2: Identify active issues
active_issues = get_active_issues(period_start, period_end)
if len(active_issues) == 0:
# No active issues - carry forward all costs
carry_forward_loss(total_costs, next_period)
return
# Step 3: Calculate allocation
cost_per_issue = total_costs / len(active_issues)
# Step 4: Allocate to issues
for issue in active_issues:
allocate_cost_to_issue(issue.id, cost_per_issue, period_id)
create_allocation_transaction(issue.id, cost_per_issue, period_id)
update_issue_valuation(issue.id, cost_per_issue)
```
### **Active Issue Definition**
```sql
-- Issues are considered "active" if they have any of these activities:
-- 1. Created during the period
-- 2. Modified/updated during the period
-- 3. Had comments added during the period
-- 4. Changed status during the period
SELECT DISTINCT issue_id
FROM issue_activity_log
WHERE activity_date BETWEEN period_start AND period_end
AND activity_type IN ('created', 'modified', 'commented', 'status_changed')
```
## 📊 **Example CLI Commands**
### **Cost Management**
```bash
# Register recurring costs
markitect cost add "Hosteurope Server" --type=monthly --amount=10.00 --start-date=2025-01-01
# Register one-time costs
markitect cost add "SSL Certificate" --type=one_time --amount=50.00 --date=2025-03-15
# List all costs
markitect cost list --active
markitect cost list --period=2025-03
# Update cost
markitect cost update 1 --amount=12.00 --end-date=2025-12-31
```
### **Period Management**
```bash
# Create new period
markitect period create --start=2025-03-01 --end=2025-03-31
# Calculate period costs
markitect period calculate 2025-03
# Close period
markitect period close 2025-03
# List periods
markitect period list --status=open
```
### **Reports and Analysis**
```bash
# Cost summary
markitect reports cost-summary --period=2025-03
# Issue cost analysis
markitect reports issue-costs --issue=123
# Cost trends
markitect reports cost-trends --start=2025-01 --end=2025-03
# Export for accounting
markitect reports export --format=csv --output=costs_2025_q1.csv
```
