Sellers of goods and services use different methods, promotional offers, and loyalty programs to increase consumer demand. However, product recommendation is the most popular and modern trend. In this case, sellers use various analytical systems and artificial intelligence. These methods make it possible to determine the behavioral and purchasing habits of the clients to make high-quality personal offers of goods and services in the future, so a certain buyer begins to be shown and offered the most relevant products that match his preferences and needs.

All of these recommendations are based on collected data about goods, or purchases of people with similar shopping behaviors. The main goal, in this case, is to choose from various assortment and to show the client the right goods and services that fully correspond to his interests. This method helps to follow the consumer demand and forms loyalty to the product, service, or brand. This "adjustment" may become a unique business style of the company.

A few months ago, RusHOLTS company started a project of coffee solution implementation in the VkusVill retail chain. The high marginality of the coffee business attracts many people and businesses, including large retail chains. Self-service coffee modules have been installed in VkusVill stores. The customers can make a cup of freshly brewed and aromatic take away coffee. However, we decided to implement two technological solutions. Except for the coffee modules we installed "BaristaGo" on all the coffee machines in VkusVill stores.

The "BaristaGo" solution allows customers to personalize all coffee drinks and prepare coffee according to the individual taste preferences. Some people like a stronger americano, some prefer more foam in a cappuccino. The standard settings of the coffee machine do not allow making the individual taste of drinks. However, with the BaristaGo solution, individualization has become possible. The strength of the coffee, the amount of water and milk, and the level of foam have become adjustable.

Moreover, the process of making drinks is technological and is carried out through an application that clients install on their mobile phones. After starting the application, the user enters a convenient and usable interface, where he or she selects the drink and adjusts its parameters. There is one more advantage because the order of coffee in this case is carried out in a non-contact way, which especially matters during a pandemic. The user does not need to press the buttons of the coffee machine. The settings of the parameters and the start are carried out on a personal mobile device. We have already collected primary feedback from Vkusvill customers and we can confidently remark that there are only positive reviews. We are glad to tell more about the RusHOLTS coffee solution and the BaristaGo application to everyone interested!
