i) Time Saving: TPS can process large volumes of data within a short period of time.

ii) Operational Efficiency: TPS will facilitate the smooth operations of the supermarket and will provide the base for other internal information systems.

iv) Activity Tracking: TPS assists information system managers and staff to keep track of all activities and transactions of the company, such as sales and receipts.

v) Access to a Wider Market: TPS will enable the supermarket to access potential customers to buy the goods when linked to the internet.

vi) Time Sharing: TPS facilitates the sharing of the system and its properties among multiple users working on the same transaction at the same time.

vii) Back-up: TPS provides the basic building blocks for other systems in that it has a backup in case of system failure.
