CHAPTER I: OVERVIEW OF THE TOPIC

I WHY CHOOSING THIS SUBJECT?

In the past, most of us would buy food mainly from wholesale markets, buying agents in big centers or in markets and department stores Today, the development of the digital economy has changed the business perception of the whole society It can be seen that all products and services can be introduced and "sold" on the Internet Moreover, customers increasingly need to know information about the origin and origin

of agricultural products that ensure quality and safety for health or not? Therefore, in addition to improving food quality, brand communication, and packaging improvement

to affirm quality reputation, managers need a more effective communication channel and app design is the ultimate solution selected best Owning a sales app will help businesses attract more potential customers through the internet According to the latest statistics, Vietnam currently has about 41 million internet users, accounting for about 45% of the country's population, most of which are young people with high shopping needs Moreover, nowadays, the online trend is developing day by day and is buying by many users About one third of the population uses the internet to search and look up information about services and products Therefore, when you have a sales app, your business has attracted a number of customers on the internet Without the app, you would have lost an opportunity to sell and give that opportunity to competitors

II PROJECT OBJECTIVES

Promote sales activities anytime, anywhere Customers will not have to come directly to the store or purchase according to the store's operating hours but can buy at any time This helps to maximize sales opportunities, boost sales and facilitate customers to shop, making them more satisfied

Reduce business costs Having a sales app will help save a lot of costs for store rental, warehouse and human resource costs In addition, having a sales app also makes the payment of customers convenient and easier Customers can pay via ATM cards, through electronic payment methods

Having a separate sales app for the business will also help improve the reputation and brand value of the business The face of a business on the internet is the app and the colors, features and information on the app will fully reflect the image of the business with the customer, contributing to affirm the company's brand value in the hearts of the public
