Introduction

This feature enables users to convert existing Excel-based inventory lists into a barcode/QR code system for efficient inventory management. The system will read product codes from Excel files, generate corresponding barcodes or QR codes for printing, and provide a mechanism for users to scan codes and update inventory levels in real-time.

Requirements

Requirement 1

User Story: As an inventory manager, I want to import my existing Excel inventory list, so that I can convert product codes into scannable barcodes/QR codes without manual data entry.

Acceptance Criteria

  1. WHEN a user uploads an Excel file THEN the system SHALL parse and extract product codes, descriptions, and current inventory levels
  2. WHEN the Excel file contains invalid data THEN the system SHALL display clear error messages indicating which rows have issues
  3. WHEN the Excel file is successfully processed THEN the system SHALL display a preview of the imported data for user confirmation

Requirement 2

User Story: As an inventory manager, I want to generate printable barcodes or QR codes for each product, so that I can physically label items on shelves for easy identification.

Acceptance Criteria

  1. WHEN a user selects products from the imported list THEN the system SHALL generate barcodes or QR codes containing the product information
  2. WHEN generating codes THEN the system SHALL allow users to choose between barcode and QR code formats
  3. WHEN codes are generated THEN the system SHALL provide a printable layout with product codes, descriptions, and corresponding barcodes/QR codes
  4. WHEN printing THEN the system SHALL support standard label sizes and printer formats

Requirement 3

User Story: As a warehouse worker, I want to scan barcodes/QR codes to quickly identify products, so that I can update inventory levels without manual lookup.

Acceptance Criteria

  1. WHEN a user scans a barcode or QR code THEN the system SHALL immediately display the product information and current inventory level
  2. WHEN a product is identified THEN the system SHALL allow the user to update the inventory quantity
  3. WHEN inventory is updated THEN the system SHALL save the new quantity with a timestamp
  4. WHEN a scan fails or code is not recognized THEN the system SHALL display an appropriate error message

Requirement 4

User Story: As an inventory manager, I want to export updated inventory data, so that I can maintain records and integrate with other systems.

Acceptance Criteria

  1. WHEN a user requests data export THEN the system SHALL generate an Excel file with updated inventory levels
  2. WHEN exporting THEN the system SHALL include timestamps of last updates for each product
  3. WHEN exporting THEN the system SHALL maintain the original Excel file structure and formatting where possible
  4. WHEN export is complete THEN the system SHALL provide download functionality for the updated file

Requirement 5

User Story: As a system administrator, I want inventory data to be stored reliably, so that updates are not lost and the system remains performant.

Acceptance Criteria

  1. WHEN inventory data is updated THEN the system SHALL persist changes immediately to prevent data loss
  2. WHEN multiple users access the system THEN the system SHALL handle concurrent updates without data corruption
  3. WHEN the system stores data THEN it SHALL maintain data integrity and provide backup capabilities
  4. WHEN querying inventory data THEN the system SHALL respond within 2 seconds for typical operations
