What is the Inventory Management?
Most often, this is believed to be an activity thanks to which companies ensure a stable supply of goods in order to meet customer demand. Inventory management aims to have the right products in the right place at the right time. However, one measurement of good inventory management is inventory turnover, not the customer happiness. The turnover reflects the frequency of product being sold during a given period. A business does not want more inventory than sales. Low inventory turnover can lead to unsold stock, losses, and sometimes even bankruptcy. Well, the good inventory management system is the backbone of retail success, ensuring that the right products are available at the right time to meet both customer demand and seller profit.
Inventory management involves tracking products from manufacturers to warehouses to points of sale, maintaining optimal stock levels, and minimizing both stockouts and excess inventory.
As the retail landscape evolves, advanced technologies and innovative practices are transforming how inventory is managed, offering significant competitive advantages to businesses.
The Future Belongs To Retail Chains
For years, independent stores have been facing increasing competition from retail chains. And even if they stay independent, they create associations or group themselves into small chains to face the competition of large players. Nowadays, it is difficult to find, eg. an independent cosmetic store not being a member of some chain. This changes the approach to inventory management.
While a single point of sale must deal with logistics on its own, allocating usually modest human and time resources, big chains solve problems at the level of hundreds and even thousands of POS using proportionally fewer resources. Thanks to mass management processes, chains can be much more efficient, profitable and competitive than independent stores.
This is why the future of retail belongs to chains, even if only regional ones, which is nothing new in the era of shortening supply chains, gaining even greater momentum in almost all industries since the Covid-19 pandemic. Competition between retail chains will largely focus on optimizing resource management and reducing costs. Those that can best cope with these challenges will grow faster and take larger market shares.
