Development and Implementation of Point of Sale System (POS): Profitability Measurement for Retail Business

Geraldine B. Mangmang


This study is an innovation of POS system wherein notification features through screen pop-ups of overdue payments and out of stock items were integrated. The developed system gave satisfaction to an enterprise-Sheallzy Enterprises,located in Malitbog Southern Leyte. The software product is created in Microsoft Visual Studio 2012 with Microsoft SQL Server 2005 as the database. The ISO/IEC25010:2011 standard was used as a model for evaluating the created software. This study used a developmental evaluative design which is an approach that supports innovation. A research questionnaire was used to assess the performance of the existing system and the developed software. The research instrument was validated by an information technology expert to ensure the validity of the questionnaire. The target client of the study served as the respondents of the study in order to achieve the purpose of the software,specifically,the owner and the cashier of the business. The quality in use model(i.e. effectiveness) and product quality model (i.e. usability, performance efficiency) were used to assess the quality of the new system. Results revealed that the management is very satisfied in the performance of the new software. The developed system is efficient, and effective compared to the existing system. Findings of the study proved that embracing technological advancement can improve the whole business operation. It is recommended that retailers who deal with credit transactions use the system in order to have close monitoring of overdue payments.
