Design of a Web-Based Sales Information System Using the Laravel Framework for PT Surya Sentosa Dealership, Sarolangun Regency

Abstract

Vehicle information and ordering services at PT Surya Sentosa in Sarolangun Regency rely on brochures and direct communication, while initial Vehicle Order Letter (SPK) data are recorded manually and service appointments are arranged through WhatsApp. This study aims to design and develop a web-based sales information system that integrates vehicle information, SPK submissions, and customer services. Data were collected through observation, an interview with the branch manager, and document analysis. Development followed the Waterfall model using Unified Modeling Language, Laravel 12, and MySQL, with black-box functional testing. The system provides public, customer, administrator, and manager areas supporting vehicle catalogs, variant-specific financing packages, quotation requests, test drives, SPK revisions, recorded leasing survey results, purchase guarantee payments, managerial decisions, signed document delivery, and service bookings. The database contains 26 application tables and one migration table. All 26 test scenarios produced the expected outputs. These findings indicate functional conformity within the tested prototype; service time improvements, user satisfaction, and usability have not been measured. Purchase guarantee payments and leasing survey results still require manual verification or recording. Further development should include user evaluation and operational deployment.
