About the book

From the book.

This cheat sheet is one appendix of Barcode or Bleed: The Real Cost of Manual Inventory — and How to Stop Paying It, the field guide for warehouse owners and ops directors who have never barcoded.

No theory. No futurism. Just the blunt financial case for barcoding the operation you have right now, and the first ninety days of doing it.
