An inventory system is a framework for managing the flow of goods within an organization. This includes forecasting demand, ordering and receiving products, and tracking their movement through the warehouse and distribution channels.
There are two main types of inventory systems: periodic inventory systems and perpetual inventory systems.
Periodic inventory systems update inventory levels only at regular intervals, such as monthly or quarterly. This system requires manual data entry for each item and can be prone to human error.
Perpetual inventory systems continuously update inventory levels based on real-time data from the supply chain. This means that inventory is always up-to-date and accurate.
Periodic inventory systems are often used in small businesses or organizations with predictable demand and limited inventory turnover.
Perpetual inventory systems are often used in large corporations with complex supply chains and high inventory turnover. This system is more efficient and accurate and can help to reduce carrying costs.
Here's a table comparing the two types of inventory systems:
| Feature | Periodic Inventory System | Perpetual Inventory System |
|---|---|---|
| Update frequency | Regularly (monthly or quarterly) | Real-time |
| Data entry | Manual for each item | Continuous |
| Inventory accuracy | Can be less accurate | More accurate |
| Suitable for | Small businesses with predictable demand | Large corporations with complex supply chains and high inventory turnover |
