Perkembangan teknologi informasi mendorong pemanfaatan e-commerce sebagai media transaksi digital bagi pelaku usaha, termasuk UMKM. Toko Bunga Untukmu masih melakukan pemesanan melalui media chat sehingga data pesanan tidak terintegrasi, berpotensi menimbulkan kesalahan pencatatan, keterlambatan konfirmasi pembayaran, serta pelanggan tidak dapat memantau status pesanan. Penelitian ini bertujuan merancang dan membangun sistem informasi e-commerce berbasis Business-to-Consumer (B2C) guna mendukung pemesanan dan manajemen pesanan bouquet secara terpusat. Metode penelitian meliputi observasi, wawancara, dan studi pustaka, dengan pengembangan sistem menggunakan model Waterfall. Perancangan sistem dilakukan menggunakan Unified Modeling Language (UML) dan Entity Relationship Diagram (ERD), sedangkan pengujian sistem menggunakan Black Box Testing dan White Box Testing. Sistem dikembangkan menggunakan PHP dengan framework Laravel dan basis data MySQL. Hasil penelitian menunjukkan bahwa sistem mampu mengintegrasikan proses pemesanan, pembayaran, dan pengelolaan pesanan dalam satu platform, sehingga meminimalkan kesalahan pencatatan, mencegah pesanan terlewat, serta memudahkan pelanggan memantau status pesanan.

This study aims to design and develop a Business-to-Consumer (B2C)-based e-commerce information system to support centralized bouquet ordering and order management. The techniques of collecting data used in this study include observation, interviews, and literature study, while the system development method applies the Waterfall model. Designing the system, it uses Unified Modeling Language (UML) and Entity Relationship Diagram (ERD), while system testing uses Black Box Testing and White Box Testing.The system is developed using PHP with the Laravel framework and MySQL for Database.
