Definition of Inventory Forecasting
Inventory forecasting is essentially a businesses attempt at guessing how much stock you will need in the future. It uses information from the past, trends, and what might happen soon to infer what might occur in the future. This helps make sure a business has enough goods to give customers without having too much extra stock.
Having too much can tie up money that could be used for other things. The key points needed for good inventory forecasting are knowing how much stock you have now, any orders not filled yet, old trends, and what demand is expected during different times of year.
Importance of Efficient Inventory Forecasting
Right forecasting can keep your business from extra costs. Extra inventory costs money to store and it may go bad over time. Having less product than you need can also be a problem.
This is where good inventory forecasting comes in handy.
Inventory Forecasts use data like current stock levels, purchase orders, past trends, seasonal changes and how customers buy certain items to guess future sales. This way businesses know what products they'll need more of or less of in the future and when they should order them.
They can make sure there's just enough stock - not too much or too little. This helps save money by avoiding waste from spoiling items and storage fees for excess products.
Core metrics used in Inventory Forecasting
Understanding inventory forecasting starts with key facts. These facts or metrics make it possible to plan for future needs. Five core metrics used in inventory forecasting are:
- Current Inventory Levels: This shows the amount of stock on hand at any time.
- Outstanding Purchase Orders: This is a count of items yet to be delivered by suppliers.
- Historical Trendlines: This points out past trends in sales, and helps guess future ones.
- Forecasting Period Requirements: This metric determines the time frame for which we need a forecast.
- Expected Demand and Seasonality: These measure how much clients will want items, and if they would buy more during certain seasons.
- Maximum Possible Stock Levels: Knowing this limit helps stop oversupply problems.
- Sales Trends and Velocity: A fast look at how quick goods sell over a given period.
The 4 Major Types of Inventory Forecasting
There are several types of inventory forecasting, including quantitative forecasting, qualitative forecasting, trend forecasting, and seasonality forecasting.
1. Quantitative Forecasting
Quantitative forecasting uses past data to guess future needs. It is a key part of inventory planning. This method is often more exact than others. To do it right, you need certain data.
