*How POS of Gomsu Supports Inventory Management*

Effective inventory management is the lifeblood of any small retail business. With the right strategies, you can eliminate waste, reduce costs, increase profits, and improve the customer experience. In this comprehensive guide, we explore 8 inventory management methods that every small business owner should adopt in 2025. By integrating these proven strategies, you can ensure that your stock aligns with your sales, demand, and budget. From FIFO to perpetual inventory system, each method has its own benefits, and we’ll highlight how each can transform your store operations.

1. FIFO (First In, First Out)

FIFO, or First In, First Out, is an inventory management technique that prioritizes selling the oldest stock first. This approach is especially beneficial for businesses that handle perishable items or products with an expiration date.

Using FIFO helps reduce spoilage, ensures product freshness, and maintains customer trust. If you're managing a store with dairy products, snacks, or over-the-counter medicine, adopting FIFO can lead to smoother operations and fewer losses. Convenience stores often use FIFO by rotating stock—placing new items behind the old ones.

By integrating FIFO into your inventory system, you can maintain quality control, reduce expired product waste, and enhance your overall inventory management.

2. LIFO (Last In, First Out)

LIFO, or Last In, First Out, is another common inventory accounting strategy. It assumes that the latest items added to inventory are sold first. While not suitable for all industries, LIFO is frequently used for financial purposes because it reflects current costs more accurately in times of inflation.

Hardware stores, for example, use LIFO to align their sales prices with the most recent supplier costs. Though LIFO might not always be the best fit for perishables, it works well for items with stable shelf lives. In rising markets, LIFO can reduce taxable income by assigning higher cost values to sold inventory.

A solid LIFO system can be instrumental in improving your financial forecasting and aligning your inventory management with market trends.

3. Just In Time (JIT)

Just In Time, or JIT, is an inventory method that reduces overhead by purchasing stock only when needed. JIT allows small businesses to minimize storage costs and avoid the burden of overstock.

With JIT, you rely on accurate sales forecasts and dependable suppliers. Vape shops and specialty retailers often use JIT by analyzing weekly trends and ordering only what is necessary.

However, JIT is not without risk—if a supplier fails to deliver on time, you may face stockouts. But when managed well, JIT is a lean, efficient model that supports modern inventory management.

4. Economic Order Quantity (EOQ)

EOQ, or Economic Order Quantity, is a formula-driven method that determines the ideal order size to minimize holding and ordering costs. By using EOQ, businesses can reduce excess inventory while ensuring sufficient stock levels.

Liquor stores preparing for the holiday season often apply EOQ to balance demand and storage capacity. EOQ supports smarter purchasing decisions by taking into account order frequency, demand rate, and storage cost.

Implementing EOQ allows you to allocate capital efficiently, avoiding bulk purchases that tie up resources or frequent reorders that inflate costs.

5. Average Costing

Average costing is a simplified inventory valuation method where the cost of goods sold and remaining inventory is based on the average price of all purchased items. Rather than tracking price changes for each product batch, average costing ensures consistency.

This method is widely used in hardware stores, where items like fasteners may be bought at varying prices. With average costing, pricing remains stable, and reporting is simplified.

Average costing helps in maintaining margin integrity, especially for businesses with frequent restocking. It also reduces accounting complexity and improves pricing transparency.

6. Cycle Counting

Cycle counting is a continuous inventory auditing method where small subsets of inventory are checked regularly. Instead of pausing business operations for a full inventory count, cycle counting divides the process into manageable parts.

Tobacco shops often use cycle counting to monitor high-volume items weekly and rotate other checks monthly. This method improves accuracy without disrupting daily operations.

By adopting cycle counting, businesses gain real-time insight into inventory health, identify shrinkage early, and maintain accountability across store sections.

7. ABC Analysis

ABC analysis is a categorization method that helps prioritize inventory based on its impact on overall sales. Items are grouped into:

A: High-value, high-margin items requiring frequent monitoring
B: Moderate-value items needing regular reviews
C: Low-value items needing minimal oversight

Liquor stores might check expensive bourbons (A) more often than vodka (B) or mixers (C). ABC analysis ensures that resources are focused on the products that contribute the most to your revenue.

With ABC analysis, inventory management becomes targeted and efficient, enhancing the value of each employee's time and effort.

8. Perpetual Inventory System

A perpetual inventory system uses real-time updates to track inventory changes as they happen. Every sale, return, or restock is recorded instantly, eliminating the need for end-of-day reconciliation or manual spreadsheets.

Convenience stores using a perpetual inventory system can monitor stock with pinpoint accuracy. When a soda is sold, it’s deducted immediately from the system.

The perpetual inventory system offers enhanced data visibility, better forecasting, and less risk of stock errors, making it ideal for dynamic, fast-paced retail environments.

Why Inventory Management Matters in 2025

Effective inventory control is about more than counting stock—it’s about making informed decisions. Every small business faces unique challenges, and choosing the right inventory management method can be the difference between chaos and profitability.

Whether you choose FIFO, LIFO, JIT, EOQ, average costing, cycle counting, ABC analysis, or a perpetual inventory system, the key is to find a model that aligns with your operational style and customer expectations.
