Study the information about the company and complete the company’s information:
Birds Store is a company based in Serbia. It was opened in summer 2022. It has two clothes shops in Belgrade and one in Novi Sad. All their goods come from France and Italy. Birds Store doesn’t have any warehouses to store delivered goods. For that purpose, they use additional storing rooms in every store. Overall, there are 18 employees. Clients can order clothes online and take from one of the stores. Dushan Jovich, the sales manager, is facing some troubles with his time-management now because of a number of handwriting sales reports which he needs to fill in every day. Moreover, customers are constantly complaining to sales assistants about the availability of goods in offline stores — the website every time shows the wrong information about the range of clothes. One of administrators, Elena Bajovich, also has some problems but with slow computers at work: while she is trying to change the information on the website, everything starts to freeze.
