This study aims to redesign the accounting information system for SDI Salafiyah 03 using Business Process Model and Notation (BPMN) to develop an integrated educational finance platform called EduFinancePro. Employing a qualitative case study approach, data were collected from key financial personnel through interviews, direct observations, and document analysis. The research focused on four financial processes: tuition fees, BOS funds, donations, and payroll. Through BPMN-based modelling, the study analysed the transformation from manual to digital workflows, enabling data entry automation, real-time reporting, and audit trail monitoring. The collected data were analysed using a qualitative descriptive method, involving data reduction, data display, and conclusion drawing. To ensure reliability, the study utilised triangulation and member checking. Additionally, the financial workflows were modelled using Bizagi Modeller 4.1 to visualise the transformation from manual to digital systems. The findings suggested that even resource-limited schools can adopt digital systems to enhance financial accountability and operational efficiency. Despite facing infrastructural and personnel readiness challenges, this study demonstrates that BPMN can be effectively applied in primary school contexts. Future research is encouraged to quantitatively evaluate system performance and scalability across various educational institutions.
