Ngày nay, đời sống của con người ngày một phát triển kéo theo nhu cầu mua sắm, buôn bán của con người ngày càng tăng cao. Công việc quản lý của các chủ cửa hàng tạp hóa lớn nhỏ ngày càng khó khăn và phức tạp hơn. Có rất nhiều giải pháp phần mềm được đưa ra để giải quyết vấn đề này, nhưng nó đắt và khó áp dụng cho các cửa hàng quy mô vừa và nhỏ.Qua nghiên cứu, học hỏi từ thầy cô và bạn bè về giải pháp quản lý bán hàng kết hợp với quá trình khảo sát thực tế trên nhiều cửa hàng, em muốn đưa ra giải pháp bán hàng cho cửa hàng vừa và nhỏ. Hi vọng sản phẩm này có thể giúp các nhà quản lý kiểm soát được toàn bộ quá trình kinh doanh của cửa hàng mình.Vì vậy, em đã thực hiện dự án “XÂY DỰNG CHƯƠNG TRÌNH QUẢN LÝ BÁN HÀNG” cho cửa hàng tạp hóa ABC. Được sự hướng dẫn tận tình của thầy Trần Xuân Sang em đã hoàn thành bài báo cáo đồ án này. Mặc dù chúng tôi đã cố gắng hết sức tìm hiểu, phân tích, thiết kế và lắp đặt hệ thống nhưng không thể tránh khỏi những thiếu sót. Tôi mongADO nhận được sự thông cảm và góp ý của bạn. Xin chân thành cảm ơn.
