2. Uttam Kumar Gupta of Std. XII would like
to express my sincere thanks to my
computer teacher “Amit Sir” for assigning
me this project. I feel extremely lucky to
have been given a golden chance or
opportunity to work under such a highly
experienced teacher.
Secondly I would also like to thank all my
family members without whose support it
was impossible for me to complete this
project.
Last but not least I would also like to
thank all my friends provided me some
suggestion in completing this project.

3. Thank You!

A computer shop management system sells various types of
hardware and software accessories such as Laptop, Antivirus
and Keyboard etc. It’s very hard for the shopkeeper to
remember their cost price and in what price these items to
be sold. As the market goes up and down for various
products daily, so there should be some proper medium
through which prices of these items can be changed
frequently without any problem. There are many customers
who will make their payment online, so there should be a
medium to take their credit card as input and reduce exact
amount from their account. This computer shop
management system will enable its user’s keep their
customers report secure, so that next time these customers
when arrive to their shop, do not have to enter their details
again. Buyers will also able to select products options while
purchasing through computer screen and can make their
payment from that particular screen and pick up their
materials which they have selected at the pickup center
within the shop.
