Is there a way to create a bestselling assortment mix every time?

Assortment planning is one of the biggest challenges in fashion retail and one that can make or break company performance. Determining which products customers will want to buy and estimating the right amounts to order for each location is an immense task that merchandisers have to perform regularly. Order too little of an in-demand item and you’re leaving money on the table. Order too much and you’re not only reducing your profit margins but also wasting materials and polluting the environment when getting rid of them. In fact, nearly 20% of global wastewater is produced by the fashion industry, as much as 12% of fibres are still discarded on the factory floor, and 25% of garments remain unsold according to McKinsey. Those are staggering statistics, but what if there was a way to minimize risks when it comes to assortment planning and instead create an ideal product mix that boosts your profits and reduces waste every time?

What is an assortment mix simulator?

Usually, merchandisers have to work together with designers and vendors to come up with the ideal product mix that will sell. They have to consider past performance, trends, markups, and at times rely on their gut instincts. Intricate and enormous workload has to be performed to accomplish the ultimate goal - create a strong assortment that will keep the brand profitable and customers satisfied. However, some merchandisers struggle to develop this ideal product mix and may require a little help from artificial intelligence and machine learning technologies. It is for those merchandisers that we have developed a matrix simulator platform that creates an optimized assortment mix for the next season at the click of a button.
