Our project “entitled Design and implementation of automated Billing system for supermarket” (using Maris Supermarket Owerri Imo State as our case Study), which uses manual mode of operation.

The supermarket has been experiencing so many difficulties with this mode of operation; which includes;

Lots of paperwork:Existing system uses so many papers and even a small transaction require many papers to fill.

Secondly; Difficulty in reports generation. Either no reports generation in a current system or they are generated with great difficulty; reports take time to generate in the current system.

Finally, the project is to computerize the Front Office Management of the supermarket to develop software which is user friendly, simple, fast, and cost – effective.
