Any business that deals with physical goods relies heavily on inventory management. It enables you to make the right products in the right quantities, to balance customer demand against production efficiency. A good inventory management system can revolutionize your business, allowing you to improve on matters such as inventory control, order management – and even lean inventory management.
In this comprehensive guide, we’ll discuss the different types of inventory management systems along with the pros and cons, as well as take a look at the possible use cases and available solutions to help you make the right decision
What Is an Inventory Management System?
An inventory management system is a tool or process that helps organizations and companies manage stock levels, avoid stock outs, and maintain proper balance between demand and supply. They come from simple, manual solutions such as spreadsheets through to more advanced facilities management software incorporating barcodes, RFID, or cloud technology. Intelligent systems enable inventory control with accurate stock information, simplify order management by managing reordering, and helps audit inventory to ensure accuracy.
Why Inventory Management Matters
Bad inventory management causes stock outs, lost sales and stock holding that ties up capital. In fact, according to a 2019 study conducted by Asset Panda, brands like Target lose vast sums of money because of inefficient inventory control — with inventory mismanagement costing even shorter small fortune. Benefits of using inventory management system delivers:
- Cost Savings:
Reduce holding costs by up to 20% through optimized stock levels.
- Customer Satisfaction:
Maintain delivery dates to increase retention by 15% (Inventory Management Case Studies).
- Productivity:
Automatically complete workflows and save up to 10h/week on routine tasks.
- Lean Operation:
Reducing waste, consistent with lean inventory management.
As Warren Buffett noted, “Good inventory management is good business management.” The right inventory management system ensures inventory control, boosts order management, and saves up to 20% in costs, transforming your operations
12 Types of Inventory Management Systems
Here, we explore the 12 most common types of inventory management systems, detailing their mechanics, advantages, challenges, and ideal applications. Each section includes real-world examples, industry insights, and practical tips to help you implement or optimize these systems effectively.
1. Periodic Inventory System
In the periodic inventory system, stock is physically counted at fixed intervals (e.g. monthly, quarterly) so that records can be updated. The usual calculation businesses make is their cost of goods sold (COGS), which is starting inventory plus purchases minus ending inventory. It’s a manual task frequently combined with basic tools such as spreadsheets.
How It Works:
- Stock is counted during a scheduled audit.
- Records are updated post-count, adjusting for sales and purchases.
- COGS is calculated periodically, typically for financial reporting.
Advantages:
- Requires low technology, thus cost-effective usually around $100 per year for basic tools).
- Easy to implement, great for small businesses with a small staff or tech capabilities.
- Applicable to low turnover stocks with stable demand.
Disadvantages:
- No real time visibility, 30% of stock outs or overstock problems
- Labor-intensive, with counts taking 4–8 hours for small inventories.
- Regular inventory checks are necessary due to the susceptibility to human errors.
Best For:
Small businesses with a limited number of SKUs, such as local bookstores, cafés or craft stores.
Real-Life Example: A hardware store owned by a family does inventory four times in a given year to log all its nails, screws, and tools on a spreadsheet. This method is less expensive, but requires the store to shut down for a day to complete counts.
Industry Application:
- Retail:
Seasonal stores, such as small boutiques, employ periodic systems to control seasonal stock. - Hospitality:
Ingredients like coffee beans are monthly for cafés.
