INTRODUCTION

E-billing is the electronic delivery of financial documents to the customer

that represents and replaces the conventional paper based document.

E-billing is the delivery of electronic bills to end consumers and providing

a payment option for them.

In previous systems different worksheets were used to maintain product

list, customer list and billing information they are not able to share data

between each other.

This E-billing system is used to overcome the entire problem which they

are facing in older billing system, and making complete atomization of

manual billing system.

ACKNOWLEDGEMENT

The work is an accomplishment for the project works under the

invaluable guidance of Mr.V.D.MHASKE of department of ComputerEngineering. Behind every success there is a source of inspiration. In our case,

that source was our HOD MR.NIKHADE sir whose inspiration and

encouragement led us to complete this assignment to our satisfaction. In spite

of the busy schedule of department work they spend their valuable time for us

and acted as a friend and guide.

We also like to thank of staff member of our department and

classmates for the help they provide us.

Hence we drive a sense of satisfaction and pleasure in submitting

this project. We would like sincerely thank our guide for their guidance and

encouragement in completing this project.

We are equally thankful to assistance who are directly or

indirectly for developing the project. We are also thankful to the non teaching

staff of our Computer Department for helping us in our project.

DESCRIPTION OF THE CURRENT SYSTEM

The client uses MS Excel, and maintains their product list,

customer list, and prints the invoice, however it is not possible them to share

the data from multiple system in multi user environment, there is lot of

duplicate work, and chance of mistake. When the product price are changedthey need to update each and every excel file. There is no option to find and

print previous saved invoice. There is no security; anybody can access any

report and sensitive data, also no reports to find out the sales volume, stock

list, and summary report. This eBilling and invoicing system is used to

overcome the entire problem which they are facing currently, and making

complete atomization of manual billing and invoicing system

Then the world move towards electronic billing which creates,

processes, stores & print bill electronically by one single application. But thissystem also has some disadvantages.

The programmer then needs to build different application for

different store and the retailers. If suppose two customers needs billing

software each having different retail store the developer then needs to produce

separate application which was wastage of time.

After the deployment of the software if customer specified or

requested for a change then the developer has to recompute the logic. Suppose

there are 10 sub stores and the owner decided to add new substore containing

different products. Then the owner need to inform the developer about the

specified change and then the developer update the software by adding

requested changes. In this way the owner need to pay the extra cost for

expanding his billing software.

LIMITATIONS OF THE CURRENT SYSTEM

Current system is complex, hard to manage & time consuming.

Replication is another disadvantage of the current system.

It is tedious task to manage large amount of data.

Cannot be used for more than one retail store or shop.

Security of data & transaction is very poor.

PROPOSED SYSTEM

Customer comes in store and order for some products.Computer

operator takes customers details such as customer name and customers contact

number. Then computer operator creates bill of customer by adding product

name and quantity. The amount will generate automatically by multiplicationof quantity and rate of the product.Total amount will generate automatically

by addition of amount of each product. Computer operator do not need of

calculator to calculate the amount of the product. The person who is having

the basic knowledge about the computer can operate computer easily.By

simple clicking and editing text transactions can complete easily and

faster.The computer operator can easily see the report and print it whenever

he/she wants.

The Security is further enhanced by giving separate privileges to

Administrator & local user. The Administrator will be having all the rights

whereas local user has limited functions. So if there are major changes to

make only the administrator can perform it. Such as Backing up & Restoring

database. The product details can be easily managed by local user to add new

stock or updating existing stock details.

We have provided some utilities to secure the data and application

such as Restore, Backup, Change password. The Add/Modify store info

Utility expand the capability of the Project And provides flexibility to the user

by adding new store in the application this is the main advantage of ourproject which is not provided by traditional softwares. Here we can add more

than one store and maintain the transactions of each store separately. Only one

store will perform its operation at a time and the user can rapidly switch to

another store and perform the operations associated with it.

PROGRAM LIST

1. Frmsplash: - It is used as simple startup form which contains name of our

Project.

2. frmlogin: - Provide access to Project only to authenticate user. The user

login into application using password.

3. MDIForm1: - The main transactions start from this form. It is the main

from that provide access to other forms.

4. Product_list: - It is used to add, modify or delete a product details from

particular Retail Store or Shop.

5. Bill_frm: - Used to generate bills corresponding to that store and print it.

6. Bill_product: - It shows the stock of available products and enable user to

enter the quantity that he wanted. The details then added to Bill form.

7. frmfind_bill: - Used to find the previous Bills stored in Database. It can

also be act as Reports. The user can search Bills by Bill no., Customers name

or Date that he specifies.

8. frmutility: - Provides utility tools such as backup database, restoredatabase, change password that help to secure the data.

9. Backup: - User can take backup of database using this form. So you can

store multiple copies of data.

13


14/73

10. Restore: - In case the database is corrupted or deleted then using this

utility you can restore backup file.

11. Change_passwd: - This form enable user to change his password for

security purpose.

12. Store_info: - Shows the number of stores present in application and its

details. Users can also add/modify/delete store information.

13. frmchange_store: - If there are more than one store in application user

can rapidly switch among the stores without logging out.

14. frmAbout_us: - Shows name of the Project Developer and Project Guide.

72/73

CONCLUSION AND FUTURE ENHANCEMENT

This project will be developed to fulfill user and business requirement;

however there are lots of scopes to improve the performance of the eBilling

System in the area of user interface, database performance, and queryprocessing time.

Future enhancements for this project are as follows:

Integration with travel agent through Web Services

Electronic Data Interchange (EDI) system between banks, other credit

verification agency and their vendors

In the area of data security and system security.

Provide more online tips and help.

To optimize the query which is embedded in the system.

We can provide more ways for payment of bill.

We can build this project compatible for multiuser environment.
