Procurement processes in the Philippines include sales and purchase activities within two entities, comprising various aspects of searching, sourcing, discussion, requiring, and receipts, in post- purchase reproduction which results to a slow process, repetitive work, expensive and financially consuming. Sometimes it is tough to find a supplier because only a few of them have a website which is challenging to get low prices and rates. Hence, the E- procurement systems were made to address the solution. E- procurement has a ranking method that helps facilitate the customer's search on the products or suppliers. Present search ranking session is a common problem in making a consumer decision that takes a multi-step decision on clicking on products or supplier on the website. Thus, this study aimed to develop an eprocurement management system a centralized platform for business-to-business (B2B) and business to customer (B2C) that connects all suppliers and buyers across the entire archipelago in the Philippines where customer can avail good pricing and rate with the same quality of products. It also provides an alternative method in the procedure of a ranking system by applying the search results ranking algorithm that customer can rate suppliers by stars (0-5) according to their experience. The number of stars affects the order of search results (best supplier first). The reviews and scores are visible to users browsing the site. An average of user ratings for the supplier is calculated and displayed. Finally, to attest the general performance of the system researcher used the SUS evaluation tool with the result of the perception of the usability of the application is a 91.28 of Usability Percentile.
