🏗️ Types of Inventory Control Systems

4 best Types of Inventory Control Systems

1. Periodic Inventory System

Definition: Physical counts conducted at scheduled intervals (monthly, quarterly) to track stock levels.

Pros: Simple, low-cost, suitable for small inventories Cons: No real-time data, risk of stockouts between counts, labor-intensive

Best For: Small businesses with limited SKUs, low-value items

2. Perpetual Inventory System

Definition: Continuous real-time tracking where inventory updates instantly with each transaction.

Pros: Real-time visibility, accurate stock levels, automatic reordering Cons: Requires technology investment, complex setup

Best For: Medium to large businesses, high-value items, omnichannel retailers

3. Just-in-Time (JIT) System

Definition: Inventory arrives exactly when needed for production/sales, minimizing holding costs.

Formula: Reorder Point = Lead Time Demand + Safety Stock

Pros: Reduces carrying costs, frees up warehouse space, improves cash flow Cons: Vulnerable to supply chain disruptions, requires reliable suppliers

Example: Toyota produces cars only after receiving customer orders, with parts arriving hours before assembly

4. ABC Analysis System

Definition: Categorizes inventory into three classes based on value and importance.

Formula:

• A Items: Top 10-20% of SKUs (70-80% of value) – Tight control, monthly counts
• B Items: Next 20-30% of SKUs (15-25% of value) – Moderate control, quarterly counts
• C Items: Bottom 50-60% of SKUs (5-10% of value) – Simple control, annual counts

Example: Electronics retailer categorizes:

• A: iPhones (10% of SKUs, 75% of revenue) – Daily tracking
• B: Headphones (25% of SKUs, 20% of revenue) – Weekly tracking
• C: Phone cases (65% of SKUs, 5% of revenue) – Monthly tracking

📋 2025 Best Practices: In-Depth Guide

How Do Inventory Control Systems Improve Efficiency?

1. ABC Analysis (Pareto Principle)

Implementation Steps:

1. Calculate Annual Consumption Value: Unit Cost × Annual Demand
2. Rank Items: Sort by consumption value (highest to lowest)
3. Classify:
   • A: Top 10-20% (70-80% value)
   • B: Next 20-30% (15-25% value)
   • C: Bottom 50-60% (5-10% value)
4. Apply Controls:
   • A Items: Weekly cycle counts, tight security, frequent forecasting
   • B Items: Monthly counts, standard controls
   • C Items: Quarterly/annual counts, simple reorder rules

Benefits: Focuses 80% of management effort on 20% of items that generate most value

2. FIFO (First-In, First-Out)

Implementation:

• Label everything: Clear date marking on all receipts
• Physical arrangement: Place older stock at front, newer at back
• Team training: Ensure all staff understand rotation procedures
• Regular audits: Verify FIFO compliance during cycle counts

Best For: Perishable goods (food, pharmaceuticals), items with expiration dates, electronics (obsolescence risk)

3. Economic Order Quantity (EOQ)

Formula:EOQ = √[(2 × D × S) ÷ H]

Where:

• D = Annual demand (units)
• S = Ordering cost per order ($)
• H = Holding cost per unit per year ($)

Example: Retailer sells 1,000 units/year of a product. Ordering cost is $50/order, holding cost is $2/unit/year.EOQ = √[(2 × 1,000 × 50) ÷ 2] = √[100,000] = 316 units

Interpretation: Order 316 units per order to minimize total inventory costs

Adjustments: Recalculate EOQ quarterly for seasonality, demand changes, supplier cost changes

4. Real-Time Inventory Tracking

Technology Stack:

• Barcode scanners: $50-$200 per device
• RFID tags: $0.10-$0.50 per tag (passive), $20-$50 (active)
• IoT sensors: Monitor temperature, humidity for perishables
• Cloud WMS: Real-time sync across all channels

Implementation:

1. Start with critical SKUs: Don’t track everything at once
2. Integrate systems: Connect POS, e-commerce, warehouse management
3. Set up alerts: Automatic notifications at reorder points
4. Train staff: Ensure scanning protocols are followed

ROI: Companies using real-time tracking reduce stockouts by 40% and carrying costs by 25%

5. Safety Stock Management

Formula:Safety Stock = (Maximum Daily Sales × Maximum Lead Time) - (Average Daily Sales × Average Lead Time)

Example: Product sells 10 units/day average, but up to 15 units/day during peak. Supplier delivers in 5 days average, but up to 8 days during disruptions.Safety Stock = (15 × 8) - (10 × 5) = 120 - 50 = 70 units

Service Level Approach: For 95% service level, use z-score (1.65)Safety Stock = Z-score × Standard Deviation of Demand × √Lead Time

Best For: Critical items, variable demand/supply, high stockout costs

---

6. Cycle Counting & Physical Audits

Implementation:

1. ABC-based frequency:
   • A items: Count monthly (12×/year)
   • B items: Count quarterly (4×/year)
   • C items: Count annually (1×/year)
2. Schedule during low activity: Minimize operational disruption
3. Train counters: Ensure consistency in counting methods
4. Investigate discrepancies: Root cause analysis for variances >2%

Best For: High-value items, regulated industries (pharma, aerospace), large warehouses

7. Inventory Forecasting & Demand Planning

Methods:

• Moving Average: Average of last 3-6 months (simple, stable demand)
• Weighted Moving Average: Recent months weighted higher (trending demand)
• Exponential Smoothing: Adjusts for trends and seasonality
• Machine Learning: AI analyzes multiple variables (promotions, weather, economic indicators)

Best For: Seasonal products, promotional items, new product launches

8. Supplier Relationship Management & Diversification

Strategies:

1. Maintain 2-3 suppliers for critical SKUs → reduces single-source risk
2. Use SLAs and scorecards: Track delivery performance, quality, lead times
3. Negotiate volume discounts: Leverage purchase history for better terms
4. Collaborative planning: Share forecasts to secure priority during shortages

Best For: Global sourcing, manufacturing, just-in-time operations

9. Warehouse Organization & Layout Optimization

Principles:

• Fast movers near packing: Place high-velocity items closest to shipping area
• ABC zone layout: A items in most accessible zones, C items in harder-to-reach areas
• Clear labeling: Barcodes, RFID tags, visual cues for pickers
• Regular layout reviews: Analyze pick paths quarterly to identify inefficiencies

Best For: Fulfillment centers, e-commerce warehouses, distribution centers
