PLS READ THE QUESTION DONT COPY PASTE WRONG ASNWER

A stationery store has been running for 10 years and is located near a campus where you are studying in USA. You often stop by this store to buy stationery, markers, rulers, and photocopies of necessities for college. So far, the store runs manually which means that sales transactions are all recorded manually because so far you are served directly without going through a computer or system.

Although when the new stock comes, it turns out that the owner still uses microsoft excel to record purchases, this you know from conversations with the store owner. Because you are a frequent visitor to this store, one day the owner said that he will soon move to another city in 3 months because of urgent matters and the store will be taken care of by his son. His son has a place to live in Bogor so he is likely to recruit staff to guard the store. So far, there have never been employees because the owner has been guarding his own store so far, the owner feels that there is no need to use the system and because the products sold are also not too many so there is actually not so much problem. As a student majoring in Information Systems, of course, you offer the owner to be able to use the system only so that the store can be left to employees and be more controlled. A simple cashier system that can record purchases and sales transactions. Because the owner has never tried and knows how this kind of system works, then you provide some references that are currently very much online and can be downloaded via smartphones. The store owner seems very interested in your explanation, especially if you already know the business process of similar applications. Next week When you visit the store again, the shop owner says that he has had a lot of discussions with his son and finally they have 1 plan

The first plan: is that the store continues to run as usual but uses a system so that it can be left to employees and it is easier to control sales and purchases (starting from purchases to suppliers, recording new products, sales transactions, and sales reports)

The shop owner also had doubts between the two options but what is clear is that the shop owner said that he prefers to create his own system from scratch rather than buy a ready-made one because it adjusts to his wishes. Therefore, seeing your abilities, the shop owner intends to recruit you to develop his system. You agreed to help and you also brought in some friends and formed a project team. Of course, you are paid professionally.
