QR Inventory turns your phone into a complete inventory and asset tracking system. Scan QR codes individually or in bulk, or use voice commands to record inventory and asset transactions. Access current stock counts, asset locations, item specifications, and documentation using natural language voice queries or a QR code scan. Record inventory transactions with all additional details using continuous QR code scanning - no extra navigation and clicks until all transaction batch is scanned. QR Inventory works well for: * Field-based businesses with multiple locations * Manufacturers needing lightweight software with real-time inventory and WIP tracking * Construction and mechanical contractors tracking tools, parts, and materials across trucks and job sites * Warehouses needing a flexible, real-time inventory system Businesses that lose tools, delay projects due to shortages, or make unnecessary purchases because of poor inventory visibility can benefit from QR Inventory. If you are still using spreadsheets and manual notes because inventory software feels too expensive or complicated, QR Inventory is for you. It is fast to implement and easy to use, with an intuitive interface, efficient navigation, fast QR code scanning, and natural language voice commands. WHAT YOU CAN DO WITH QR INVENTORY * Track supplies, parts, materials, equipment, tools, assets, and samples. * Bulk scan QR code or barcode labels using your phone camera — no external hardware required. * As employees record transactions, stock counts and asset locations update in real time. * Maintain a complete audit trail showing: - When materials were received and delivered - When inventory was used and for which project - Who has tools and equipment - When assets were checked out and returned * Records can include date, time, employee, GPS location, photos, signatures, and custom fields. * Check current stock across all locations, locate tools and equipment, and access specifications, documentation, and operating instructions. * Ask questions in natural language such as: "Where do we have Widget A?" "What is the warranty expiration for pumps?" "What inventory is available in the Boise warehouse?" Or scan a QR code to instantly access item information. * Use photo attachments for visual documentation including damaged stock, serial plates, receipts, and completed work. * Capture signatures on a smartphone to confirm deliveries or equipment check-out and check-in. * Use your phone to order materials in the field. Select frequently ordered items or use QR code scanning. Requests can trigger approval and fulfillment workflows, while scanning delivered items updates PO status in real time. * Track generic and serialized assemblies, including component serial numbers for full traceability. * Track inventory stored in pallets, bins, totes, and other containers. Record inventory movement with QR code scanning. When a container moves, all inventory inside moves automatically with it.
