#5🏗 Procurement Management System For Construction Industry

This is my individual part of the Case Study implementation of the 3rd Year 2nd Semester - Case Studies in Software Engineering (CSSE) module. Here we try to solve the difficulties faced in the procurement procedures in the construction industry. As a solution we have created a Web application and a mobile application, whereas this is a the Mobile Application, implemented with React-Native, NodeJS, ExpressJS and MongoDB.

Here I have implemented the part:
Once a Site Manager add a purchase order, it should be sent for Procurement Department for approval. Once it's approved they make a quotation and send it to the Supplier. Supplier can view those quotations, make a invoice and send back it to Procurement Department. Those invoices view and find the best one by Procurement Department and change the status accordingly. If the status is approved the Supplier can add delivery details. Those details can be viewed by Site Manager and then he/she can make a relevent payment.
