The increasing operational complexity of modern laboratories has intensified the demand for reliable digital infrastructures capable of managing high-frequency transactional records with accuracy, traceability, and secure accessibility. Conventional paper-based registers and decentralized spreadsheet repositories continue to dominate routine laboratory workflows in many institutional settings, leading to fragmented data storage, delayed information retrieval, and increased susceptibility to transcription errors. From a systems engineering perspective, these inefficiencies can be interpreted as a rise in operational latency and error propagation, where the expected processing time for record retrieval may be approximated as $T_r = n \times t_s$, with $n$ representing the number of stored entries and $t_s$ denoting the average search time per record. As $n$ increases in manual systems, $T_r$ grows linearly, thereby constraining administrative responsiveness and reducing workflow transparency. Furthermore, the absence of centralized authentication and structured logging mechanisms limits accountability and complicates audit verification in multi-user laboratory environments. To address these operational constraints, this study introduces \textit{Labsoft}, a web-based laboratory register management system engineered to digitize issue and receiving workflows while enforcing administrative governance through secure access mechanisms. The system architecture adopts a modular client--server paradigm, integrating a single-page application developed using a Vite-based interface with a RESTful backend implemented in Node.js and Express, supported by a relational database schema optimized for transactional consistency. Security enforcement is achieved through role-based access control (RBAC) and token-based authentication using JSON Web Tokens, while password credentials are protected using adaptive cryptographic hashing via the bcrypt algorithm. The platform further incorporates automated report generation, structured audit trails, and data backup utilities to ensure operational continuity and regulatory compliance. Data integrity within the system is maintained through validation constraints and duplicate-detection algorithms, formally represented as an integrity function $I_d = 1 - \frac{D_e}{N_t}$, where $D_e$ denotes the number of detected duplicate or erroneous entries and $N_t$ represents the total transaction count within a defined operational interval. The experimental evaluation was conducted using a controlled dataset comprising simulated laboratory transaction logs derived from real-world operational patterns, including sample receipt records, issue dispatch logs, and administrative user activities. Performance benchmarking compared manual register workflows with the proposed digital system across key metrics such as record retrieval latency, transaction accuracy, and system throughput. Results indicate a substantial reduction in average retrieval time and a measurable improvement in data reliability, with system efficiency quantified using the ratio $\eta = \frac{P_c}{P_t}$, where $P_c$ represents successfully processed records and $P_t$ denotes total processed transactions. Empirical observations demonstrate that centralized database indexing and automated validation routines significantly enhance operational consistency while reducing administrative overhead. The implemented architecture also exhibits stable performance under concurrent access conditions, confirming its suitability for multi-user laboratory environments requiring dependable record management. In summary, the proposed Labsoft framework establishes a secure and scalable digital infrastructure for laboratory register automation, combining structured data management, authenticated access control, and real-time audit visibility within a unified platform. The principal contribution of this work lies in demonstrating that a lightweight, web-based register management architecture can substantially improve data traceability, operational efficiency, and administrative accountability in resource-constrained laboratory settings without necessitating the complexity of full-scale laboratory information management systems.
