Inventory Inquiry: Users can view the current inventory status at any time, checking quantities and locations of items to respond to market demand swiftly. Inventory Alerts: The system triggers an alert when any item falls below the preset threshold, reminding users to restock and prevent shortages. Stock Counting: Conduct regular stock takes to verify that actual stock matches system records, addressing any discrepancies. Report Analysis: Provides various reports, such as inbound/outbound statistics and inventory turnover rate analysis, to help managers make data-driven decisions. Access Control: Permissions are assigned based on employee roles, with each role limited to specific actions, ensuring data security. System Integration: The Inventory Management System can integrate seamlessly with other business systems (e.g., ERP, CRM), enhancing overall operational efficiency. User Interface: Applications developed in PB feature intuitive graphical user interfaces, making operations simple and lowering learning curves. Customization: PB’s flexible development capabilities allow for system customization to meet specific business needs, catering to diverse operational scenarios.
