HOTEL BILLING SYSTEM
This project has been made for storing stock

particular table [Items] and these records can
be easily accessed by the person in fast
manner.

29. 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.

30. 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.

31. 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.
