For tracking and payment accountability with digital sales, internet sales and international sales, you must understand that one barcode does not satisfy all sales venues.  All three (UPCs, Bar-Codes and ISRC Codes) must be purchased for both physical sales and digital sales of the same product.  Likewise, this holds true for international sales accountability.  Don’t settle for an inexpensive one bar-code covers all purchase.  Don’t think short-term.  Protect yourself in the long-run.  Let us help you get your full reimbursement.
