Abstract

Financial record keeping in micro, small, and medium enterprises is still largely conducted manually, causing transactions to be easily missed, recapitulation to be slow, and business decision making to be less data driven. SiNaik was developed to support financial recording; however, its web-based usage remains vulnerable under unstable network conditions. This study aims to enhance SiNaik into a progressive web application to improve reliability across varying connectivity and to evaluate its quality in terms of performance, usability, and user acceptance. The study applies design science research, which includes problem identification, artifact design and development, demonstration, evaluation, and iterative improvement. The progressive web application implementation is carried out using a web app manifest, a service worker, and caching strategies. Performance evaluation uses Google Lighthouse, while usability and user acceptance are measured using the System Usability Scale and the Technology Acceptance Model with 8 micro, small, and medium enterprise respondents in Cilegon City. The results show that the Google Lighthouse performance score increased from 46 to 88, with other metrics such as accessibility reaching 94, while best practices and search engine optimization reached 100. Usability evaluation yields a mean System Usability Scale score of 80.62, indicating good to excellent usability. User acceptance is also high, with mean perceived usefulness of 4.78 and perceived ease of use of 4.72 on a 1–5 scale, indicating that the application is considered useful and easy to use. Keywords: design science research, progressive web application, system usability scale, technology acceptance model, micro, small, and medium enterprise
