<![CDATA[Twentyone is a creative service business in Sumedang that provides photography, videography, graphic design, and printing services. Its operational process still faces delayed responses to clients, overlapping booking schedules, and unintegrated order records. This study aims to design and develop a website for Twentyone creative services using the Prototype method. System development was carried out through problem identification, data collection, requirements analysis, prototype design, evaluation, iterative improvement, and implementation. The resulting system provides service information, portfolios, packages and prices, booking, payment, order-status checking, booking management, vouchers, operational expenses, transactions, fixed expenses, and reports according to the access rights of customers, Admin, and Owner. The system was developed as a web-based application using WordPress with supporting plugins and custom coding to accommodate Twentyone’s business processes. System testing used Black Box Testing by providing input data to the tested functions and comparing the actual results with the expected results. The findings indicate that the website can support booking, payment, data management, transaction processing, and report presentation in a more structured manner. The implementation is expected to improve service accessibility for customers and support the operational management of Twentyone. ]]>
