All of this information is viewed holistically to predict demand for consumer goods. You want to be flexible enough to handle sporadic influxes but also take a long-term approach.
Measuring this helps track demand for different products at different times. While they each ship an average of 5,000 orders per month, some months are much lighter than others. At its core, it predicts what, how much, and when customers will purchase. Choose your time period, the specific product or general category you’re looking at, and whether you’re forecasting demand for everyone or a specific subset of people.
It’s important to adjust future projections to account for historical anomalies. For example, perhaps you had a sudden spike in demand last year. However, it happened after your product was featured on a popular television show, so it is unlikely to repeat. Or your eCommerce site got hacked, causing your sales to plunge. Be sure to note unusual factors in your historical data when you use the trend projection method. The internal business forecasting type will uncover limitations that might slow your growth. It can also highlight untapped areas of opportunity within the organization.
This means both avoiding situations where a product is out of stock and times when unsold goods waste excess retail space.

Worse still, things reshaping customer intentions happen quite unexpectedly. Think, for instance, of the teenage climate activist Greta Thunberg.
They need more customers to grow their enterprise into a sustainable eCommerce business. They average the last three years of sales data and use that to project trends for the coming year. Historical data tells them that their best months are May and October, and the worst are December and August.
But there are technologies to improve the accuracy of demand forecasting. Honestly, it will never be 100 percent precise, yet it can be precise enough to help you achieve your business goals. Demand forecasting keeps your warehouses ready for changes in demand, so when a sudden spike in interest comes, you’ll be there to provide a quick, reliable solution for customers.
Optimize Your Inventory With Demand Forecasting
Market research can give you a better picture of your typical customer. Your surveys can collect demographic data that will help you target future marketing efforts. Market research is particularly helpful for young companies that are just getting to know their customers.
These could include trade magazine writers, economists, bankers, and professional consultants. However, being outsiders to your company, they have less of a grasp on the demand for your individual products.
Apart from analyzing huge volumes of information, smart systems continuously retrain models, adapting them to changing conditions thus addressing volatility. These capabilities enable ML-based software to produce more accurate and reliable forecasts in complex scenarios. To predict the future, statistics utilizes data from the past. That’s why statistical forecasting is often called historical.
But today, it’s absolutely true that we can use a data-based approach to predicting how humans will behave. Forecast accuracy in the supply chain is typically measured using the Mean Absolute Percent Error or MAPE.
Find a small, isolated, area that has your targeted demographic. Roll out every stage of your marketing plan including advertising, promotion, and distribution plans. Measure product awareness, penetration, market share and total sales.

Demand forecasting helps the business estimate the total sales and revenue for a future period of time. Your fulfillment company is an important partner for your demand forecasting.
Any number of factors can influence a business, and no two industries are the same. For flexible supply chains, demand forecasting tools could be the most important tools of all. Demand Forecasting is the pivotal business process around which strategic and operational plans of a company are devised. Show your forecast to the appropriate people in your company and discuss it with them. Gather input from sales and marketing, finance, production, and all other managers and then revise your forecast.
Collect And Record Data
Demand forecasting can help you spend less money on both inventory purchase orders and warehousing as the more inventory you carry, the more expensive it is to store. Good inventory management involves having enough product on hand but not too much. Good inventory management is the foundation of good demand planning. If you don’t have a handle on what you have in the warehouse, you can over- or underestimate your production. Fortunately, your 3PL services provider can help you with that. The econometric demand forecasting method accounts for relationships between economic factors. For example, an increase in personal debt levels might coincide with an increased demand for home repair services.
For example, if you create a line graph, put the months on the horizontal axis and product demand quantity on the vertical axis. If you forecasted that you will need 600 units in October and 800 in November, then place those points on the graph. You can also plot past data on the graph to compare your research data with historical data. Create a model that simulates the flow of components into manufacturing plants based on your material requirement planning schedules and the distribution flow of your finished goods. For example, calculate the lead time to receive each component including shipping time no matter where it is sourced in the world. This will give you insight on how fast you can make your product to meet the demand. The industries that use this model the most include high technology, fashion, and products facing short life cycles.
Amazon filed a patent in the field of anticipatory shipping, allowing them to accurately forecast demand at the intersection of product and neighborhood/city using AI technology. There are many factors that go into a business’s daily interactions with customers.
Factors like the prices of a product, related marketing campaigns, employment opportunities, customer economic data, and competitors in the area are all taken into account.

Demand forecasting can be valuable for all kinds of businesses. Projections on profit margins, expenditure, turnover, risk assessment, and other key elements of a business model can be very useful for business planning.
Heavily relying on machine learning algorithms, demand sensing inherits all ML pros and cons. It requires significant computing power, massive volumes of data, and a large library of pre-built models.
Considerations can include the economic outlook, growth projections for your market sector, and projected cost savings from supply chain efficiencies. Startups that have less historical data to draw on will need to base their assumptions on external data. It’s necessary to be aware that any demand forecasting system is vulnerable to anomalous events, such as the Coronavirus pandemic. Now with the new machine learning algorithms arrived, most businesses are seeking to take advantage of them in conjunction with big data to automate and optimize business processes. The forecast error needs to be calculated using actual sales as a base. There are several forms of forecast error calculation methods used, namely Mean Percent Error, Root Mean Squared Error, Tracking Signal and Forecast Bias. Demand forecasting is an always-evolving practice, with businesses learning as they go.
While you can dive into steps 2 and 3, a weekly or monthly forecasting interval may not allow for this luxury if you’re managing your forecasting in a spreadsheet. Through this process of analyzing history you’ll form a bottoms-up forecast. This will serve as your foundation to be molded by the factors in the next step.
Why Your Ecommerce Company Needs Demand Forecasting
Bottom up modelling based on purchasing intentions is not the only method available for forecasting demand for new products. In some markets, such as technology and consumer electronics, products can go through an entire life cycle in a matter of months. Such narrow windows of opportunity make it vitally important to assess demand as accurately as possible. The most damaging situation is having a stock shortage while the product is still hot, leading disappointed consumers to purchase a competitor’s product. Traditional forecasting needs two to five years of sales data to guarantee an acceptable level of accuracy.
