Your first step in establishing a working barcode inventory system is
to create a product code using either a Universal Product Code (UPC), a
stock keeping unit (SKU), or a United Nations Standard Products and
Services Code® (UNSPSC).
Getting a UPC is as simple as registering the product with Global
Standard 1 to be assigned a unique company code, which can help with the
tracking of products all over the world. A UPC helps prevent theft,
allows customers to find information about a product online, and assists
in inventory management.
SKU numbers can be manually created or used in an inventory
management software system. SKUs are often unique to a company, and are
mainly used in internal operations to keep track of stock, track
purchases, and monitor inventory.
After the barcode has been created, it’s as easy as printing the
barcode using a simple inkjet printer and a label sheet, but thermal
printers are recommended for printing the labels—thermal printers have a
lower cost than laser printers, they’re easier to maintain, and they
tend to last longer, which are all important points to consider if
you’re going to be printing potentially thousands of barcodes.
