A Secure Web-Based Investment Club Management System with Integrated Accounting and Role-Based Access Control

Abstract

Cooperative savings and investment clubs play a crucial role in domestic finance in sub-Saharan Africa, but most rely on handwritten records that are error-prone, vulnerable to fraud, and easily lost. This paper describes the design and development of an online Investment Club Management System (ICMS) that digitises the entire operating cycle of a cooperative savings and loan society. The system integrates type-safe client–server communication, role-based access control, and a structured Know Your Customer onboarding process. A four-stage loan workflow is implemented with capacity-aware guarantor allocation, alongside automated amortisation and double-entry accounting within a general ledger framework. The proposed design improves data integrity, operational transparency, and financial reporting accuracy. Experimental evaluation demonstrates reliable performance and consistency in transaction processing. The system enhances transparency and efficiency and provides an architectural template for developing secure financial management systems for community organisations.
