However, D&A Food Supply Pty is a big warehouse based in Brisbane for the major distribution of raw food (imported from Africa and Asia) to customers within the state.

There is no online payment gateway, and the customers must visitthepremises to make the payment. This is a majorinconvenience for customers which makes them feel uncomfortable and leads to losing potential revenuefor the company.

The purpose of the website is to provide a platform for customers to book and makeanonline payment for raw food. The website will also allow the customers to manage their accounts and view the status of their orders. In addition, it also provides a delivery tracking system so that the customers can scheduletheir works to receive the orders.) Using the table of content below:
