Media Digital Publikasi Indonesia en-US SAGA: Journal of Technology and Information System 2985-8933 https://journal.mediadigitalpublikasi.com/index.php/saga/article/view/547 <p>The use of manual transaction recording in Micro, Small, and Medium Enterprises (MSMEs) often causes data inaccuracies, inefficient transaction processes, and difficulties in inventory monitoring. Toko Sumber Rejeki Karangbener Kudus is an MSME that still applies handwritten sales records, leading to limited transaction documentation and delayed reporting. This study aims to design a web-based Point of Sale (POS) system to support sales transactions, inventory management, and sales reporting. The study employs a Research and Development (R&amp;D) approach using the Waterfall model. Data were collected through observation of transaction activities, interviews with the store owner, and a literature review related to POS systems and MSME digitalization. System design was carried out using structured modeling, including use case diagrams, activity diagrams, data flow diagrams, entity relationship diagrams, sequence diagrams, and user interface design. The developed system provides role-based access for cashiers, administrators, and owners. Cashiers handle sales transactions and cash sessions, administrators manage product and stock data, and owners monitor sales reports. The proposed system is expected to reduce recording errors, streamline transaction processes, and improve data organization, serving as a practical solution for MSMEs transitioning from manual to digital transaction recording.</p> Agatha Ayu Amalia Endang Supriyati Tri Listyorini Copyright (c) 2026 Agatha Ayu Amalia, Endang Supriyati, Tri Listyorini https://creativecommons.org/licenses/by-sa/4.0 2026-03-03 2026-03-03 3 3 475 486 10.58905/saga.v2025i3.547 https://journal.mediadigitalpublikasi.com/index.php/saga/article/view/546 <p>Inventory management at Hotel Guna Wijaya currently relies on manual ledgers, leading to inaccurate real-time data and risks of record loss. Key challenges include difficult stock monitoring and delayed reporting due to manual recapitulation. This study develops a web-based inventory information system to enhance transparency, stock accuracy, and reporting efficiency using the Waterfall model: requirements analysis, system design, implementation, and testing. System design utilized Unified Modeling Language (UML), while testing employed Black Box and User Acceptance Testing (UAT) focusing on Role-Based Access Control (RBAC). Results demonstrate that the system successfully prevents data duplication through a Double-Check Validation feature on item names and locations. The digitalization significantly reduces report generation time from days to seconds using a Reporting Engine integrated with WhatsApp and Email. Furthermore, the Safety Stock Alert feature effectively provides early warnings to prevent shortages. Overall, the system improves monitoring, maintains data integrity, and supports efficient managerial decision-making at Hotel Guna Wijaya.</p> Dina Surya Shahhilina Endang Supriyati Tri Listyorini Copyright (c) 2026 Dina Surya Shahhilina, Endang Supriyati, Tri Listyorini https://creativecommons.org/licenses/by-sa/4.0 2026-03-03 2026-03-03 3 3 487 497 10.58905/saga.v3i3.546
