AnggaNet is an individual WiFi voucher service provider that still manages its sales process manually, resulting in frequent recording errors and preventing customers from purchasing vouchers whenever the owner is unavailable. This study aims to develop a web-based WiFi voucher sales information system using React, Express.js, Prisma, and MySQL, integrated with WhatsApp Gateway to automatically deliver voucher codes to customers upon successful transactions. The system was developed using the Waterfall method and evaluated through Black Box Testing. This system is expected to automate AnggaNet's transaction process efficiently without requiring the owner's physical presence in every transaction.
