A barcode is a machine-readable label that identifies an item. In an inventory system, scanning a barcode replaces typing a name or code — which is faster and avoids mistakes.
Benefits
- Faster billing at the counter.
- Quicker, more accurate stock counts.
- Fewer picking and dispatch errors.
- Easier tracking of lots and batches.
Common barcode types
| Type | Best for |
|---|---|
| Code128 | Internal codes and logistics; compact and flexible |
| EAN-13 | Retail products sold in shops |
| QR code | Holds more data; scanned by phone cameras |
Setting up
- Give every product a unique code.
- Choose the barcode type that suits your scanners and customers.
- Print labels on a sticker template that fits your printer.

Frequently asked questions
Do I need a special scanner?
Most handheld USB scanners work like a keyboard. Phone cameras can read QR codes.
Can I use my supplier's barcode?
Often yes, if it is unique across your products. Otherwise generate your own.
Do barcodes need a licence?
Internal barcodes do not. For EAN-13 retail codes registered globally, check the rules of the issuing body.
