Barcode-Based Inventory Management in ERP

Why Barcode Integration Is a Game-Changer

Manual product selection during billing is slow and error-prone — especially when you have thousands of SKUs. One wrong item selection creates a billing mistake that frustrates customers and creates inventory discrepancy. Barcode scanning eliminates this entirely.

ERP systems with barcode support let your billing staff scan a product and instantly add it to the bill — with correct price, GST, and stock deduction — all in under a second.

How Barcode Inventory Works in ERP

Setting Up Barcodes

• Assign barcodes to each product in the item master
• Use existing manufacturer barcodes (EAN/UPC) or generate custom barcodes
• Print barcode labels for items without printed barcodes

Barcode Billing Process

1. Open billing screen in ERP
2. Scan barcode with USB or Bluetooth scanner
3. Product adds to bill automatically with correct price and GST
4. Scan next item — repeat in under a second per item
5. Total calculated automatically — save invoice
6. Stock deducted automatically

Barcode for Purchase (GRN)

1. Receive goods from supplier
2. Scan each item barcode during goods entry
3. Stock entered automatically — no manual typing needed
4. Purchase matched against PO automatically

Stock Audit with Barcode

Use a mobile barcode scanner to conduct stock audits. Scan every item on the shelf — ERP compares scanned quantities against system records instantly — identifying discrepancies in minutes rather than days.
