**Frontend Dashboard** - Order management UI ## Business Value for VUE Madrid ### Problem Statement Spanish bakeries struggle with: - Manual order tracking on paper or spreadsheets - Lost orders and miscommunication (especially phone orders) - No customer purchase history for relationship management - Complex wholesale order management with multiple B2B clients - Overdue payment tracking for credit accounts - No analytics on customer behavior or product popularity ### Solution Bakery-IA Orders Service provides: - **Digital Order Management**: Capture all orders across channels - **Customer Database**: Complete purchase history and preferences - **B2B Automation**: Recurring orders and automated invoicing - **Payment Tracking**: Monitor outstanding payments with alerts - **Analytics**: Customer segmentation and product performance ### Quantifiable Impact **Revenue Growth:** - 10-20% revenue increase through improved B2B relationships - 5-10% from reduced lost orders (99% order accuracy) - 15-25% customer retention improvement with history tracking - **Total: €300-600/month additional revenue per bakery** **Time Savings:** - 5-8 hours/week on order management and tracking - 2-3 hours/week on invoicing and payment follow-up -
