+# 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

+```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**
