Utilising Barcodes and QR Codes in Inventory Management: Smarter Tracking for Small Businesses
Scanning Your Way to Simpler Inventory
Have you ever spent hours trying to reconcile physical stock with what’s on your spreadsheet, only to find something doesn’t add up? You’re not alone. Manual inventory management is time-consuming, error-prone, and exhausting.
But here’s the good news: the answer might be in your hand — literally. Barcodes and QR codes have revolutionised how businesses track products, cut errors, and save hours of precious time.
This guide shows how barcode inventory and QR code tracking can make operations easier. They improve accuracy and help small businesses compete with larger ones.
Let’s unpack how a simple scan can mean smarter stock control.
What Are Barcodes and QR Codes in Inventory Management?
Barcodes
Barcodes are linear, machine-readable codes that represent data about a product. Usually found on packaging or labels, they hold numeric or alphanumeric data for scanners to read.
QR Codes
QR codes are two-dimensional barcodes. They hold more information than regular barcodes. They are square-shaped, can be scanned from multiple angles, and are often readable by smartphones.
How They Help
- Faster stock checks
- Real-time updates
- Fewer human errors
- Better visibility across locations

How Barcode and QR Code Tracking Works
1. Assign Unique Codes
Each item or SKU gets a unique barcode or QR code.
2. Print and Apply Labels
Labels are printed using barcode software or label printers and attached to stock items or shelves.
3. Scan During Movement
When stock is received, moved, or sold, the barcode or QR code is scanned using.
- Handheld barcode scanners
- Mobile apps
- POS terminals
4. Real-Time Data Sync
Scanned data is updated in the inventory software. This gives real-time insight into stock levels, location, and activity history.
Benefits of Using Barcodes and QR Codes in Inventory Technology
Speed & Accuracy
Scanning is significantly faster than manual entry. A barcode scan takes 1 second; typing a SKU can take 10+ seconds.
Error Reduction
Manual data entry has an error rate of around 1 in 300 characters. Barcode scanning? Less than 1 in 36 trillion.
Cost Savings
Reduce:
- Labour costs for stock counts
- Loss from inventory inaccuracies
- Delays in restocking
Real-Time Inventory Visibility
- Know what’s in stock at all times
- Instantly track what’s sold, returned, or transferred
Scalability
Barcoding systems work for:
- 50 SKUs in a single shop
- 50,000 SKUs in multi-warehouse operations
Barcode vs. QR Code: What Should You Use?
Feature | Barcode | QR Code |
Data Capacity | Low (up to 20 characters) | High (up to 4,000 characters) |
Scan Direction | Horizontal only | Omni-directional |
Device Compatibility | Barcode scanner | Smartphone or scanner |
Label Size | Smaller footprint | Larger, but more data-rich |
Use Case | Retail, manufacturing | Logistics, complex product info |
Recommendation: Use barcodes for basic item tracking. Use QR codes for detailed data, marketing, or traceability.
