How Digital Tools Are Transforming Demand Forecasting in Fashion Wholesale

Demand forecasting for fashion wholesale has always been a complex process, as consumer habits and trends can change rapidly without warning. Short product lifecycles and long lead times can be difficult to balance, so it comes as no surprise that in recent years buyers have been bolstering their intuition-based forecasting with data-driven analytics. These digital tools are improving demand forecasting accuracy, accelerating speed-to-market, and enabling easier scaling. 

‍

What Is Demand Forecasting in Wholesale Fashion?

Demand forecasting in the fashion industry is the process of predicting which items will be most popular with consumers, and the sizes, colorways, and styles they’ll require. It's a vital part of the wholesale supply chain that ensures brands manufacture the right amount of inventory and retailers purchase the right amount of stock for their stores.

‍

It's a particularly important and difficult process within the fashion industry, where trends change with every season, and consumer needs are constantly evolving. 

‍

Why Demand Forecasting Is Especially Challenging in Fashion Wholesale

Fashion demand forecasting has its own unique set of challenges. Firstly, fashion has a higher SKU variety than many other industries, as buyers must determine not only the sizes, but also the colors, styles, and seasons they require. Secondly, as many trends are new or emerging, there is often a very small window of opportunity to predict demand, as long lead times and overseas sourcing can slow down the process.

‍

Wholesale pre-orders can be an early indicator of demand that can help brands to plan products, however this can sometimes lead to buyers understocking an item that may later turn out to be a bestseller.

‍

Looking at sell-through data can also be helpful with demand forecasting, but if restocking takes too long, retailers can potentially lose out on sales for trending items and run the risk of their customers searching for them elsewhere. 

‍

Consequences of Bad Forecasting

• Overstocking: leads to markdowns and a loss of profit.
• Stockouts: not ordering enough of a popular item creates loss of sales.
• Cash flow pressure: cash held up in stock can stifle business growth. 

‍

The Limitations of Traditional Demand Forecasting Methods  

Spreadsheet-Based Forecasting

Any kind of demand forecasting that requires manual data entry is incredibly time-consuming. Due to the manual nature of spreadsheets, it can often be impossible to process large, multichannel data sets. 

‍

Historical Sales-Only Metrics 

This method of trend forecasting has an over-reliance on past seasons, which isn’t always the most efficient in a trend-driven industry. It also means brands and buyers are unprepared for sudden demand shocks like extreme weather or an event like COVID-19. 

‍

Human Bias & Gut-Driven Planning

While buyers with years of industry experience do have a genuine talent for reading the market, confidence in buyers’ intuition can often be overestimated. Relying solely on human instincts can also be risky, as this often leads to inconsistencies across different teams and regions.
