Assign one reliable identity
Each barcode should map consistently to the intended product variation or SKU.
Choose label data carefully
Useful labels may include product name, SKU, variation and barcode without overloading the physical label.
Use scanning at control points
Receiving, transfer, picking and stock count are common moments where scanning can reduce manual identification errors.
Handle supplier barcodes deliberately
Decide whether to use existing manufacturer codes or an internal barcode standard.
Test label readability
Printer settings, label size and barcode format can affect scan reliability.
Audit duplicate mappings
Two SKUs should not accidentally share the same scannable identifier.
The operating principle
Every event should remain connected to the product, contact or transaction that created it. That is what lets ERP explain a number instead of only displaying it.
