INTRODUCTION

HOTEL BILLING SYSTEM

This project has been made for storing stock

customer number, name , phone number,

charges for room etc. It contains addition,

modification, deletion and searching of bills,

generating of bills as per requirement. Total

amount is being calculated automatically.

AIM

The main aim of my project is to create bills

helps to store the records of customers in

particular table [Items] and these records can

be easily accessed by the person in fast

manner.

MERITS

1. Records can be stored in fast manner.

2. Any record can be easily accessed.

3. Bill can be generated as per entered bill number and

bill number is settled as primary key in the table so

that no duplicate entry can be maintained against bill

number.

DE-MERITS

1. Due to failure of electricity, no work can be

processed.

2. No multiple bills can be generated.

3. Once records are being deleted can’t be rollback

again to recover them.

Conclusion

“Hotel Bill Generating System” has been

prepared to reduce manual work and with the

help of this project total amount to be paid is

being calculated automatically in fast manner.
