The project is on Supermarket Billing. Supermarket is the place where customers come to purchase their daily using products & pay for that. So there is a need to calculate how many products are sold & to generate the bill for the customers. In this project, we have 3 users. First is the data entry operator who will enter the products in the database. Second one is the administrator who will decide the taxes & commissions on the products & can see the report of any product. Third one is the bill calculating operator who will calculate the bill & print.

Organization Overview
The project is on Supermarket Billing. Supermarket is the place where customers come to
purchase their daily using products & pay for that. So there is a need to calculate how many
products are sold & to generate the bill for the customers.
In this project, we have 3 users. First is the data entry operator who will enter the products
in the database. Second one is the administrator who will decide the taxes & commissions on the
products & can see the report of any product. Third one is the bill calculating operator who will
calculate the bill & print.

4. 4
Objectives of Proposed System
To make software fast in processing, with good user interface so that user can change it &
it should be used for a long time without error & maintenance.

5. 5
Current System
Many supermarkets use this type of billing system for a decade. It is improved many times
according to requirements of sellers & customers. It does the same work i.e. calculating the bill,
gives it to the customer & maintain proper database. They are accurate in calculation & printing,
they also generate records.
A new concept is also added in the billing system is that they also maintain relationships
with the customers who purchase more products from the store regularly. System also concerns
their requirements & gives them more commission. It also shows the overall reports which items
are required & which have cross their expiry date.

6. 6
Limitations of Current System
Every system has pros & cons so existing system have many advantages &
disadvantages. So the limitations of existing are as follows:
 User Interface:
User interface is not so much good that operators feel some problems in working.
 Graphical User Interface:
GUI is not good so the operators get bored by watching screen.
 Processing Speed:
Processing speed of the software is not so much good to operate fast.
 Flexible:
Existing system is not so much flexible that can be changed according to the operators &
customers.
 Automatic Generation of Reports:
Not able to automatic generate the reports & documents.
 Workload:
Sometimes the system hangs when workload is more.
 Error Free:
Sometimes the system gives error in the calculation in making the bill & in the information
of the products due to workload.
 Man Power:
Existing system uses so many people to operate the system.
 Resources:
System does not use the resources properly.

7. 7
Advantages of Proposed System
To reduce the limitations of the existing system there is a need to develop a new system.
The new system should concern the requirements of the customers & the sellers. It has following
quality:
 Reduction in processing cost.
 Error reduction.
 Automatic posting.
 Improve reporting.
 Automatic production of documents & reports.
 Faster response time.
 Ability to meet user requirements.
 Flexibility.
 Reduced dependency.
 Improves resource users.
 Reduction in use of paper.
 Reduction in use of man power.
Proposed system includes these above qualities including existing qualities.
