Bill Of Lading
  
A bill of lading is what you wish you had when your valuable package mysteriously “goes missing” in the mail.
In short, it makes sure stuff doesn’t get stolen when it’s shipped from point A to point B.
A bill of lading is a legal document between the goods-seller (known as the “shipper”) and the goods-transporter (known as the “carrier”). The carrier, shipper, and goods-receiver all sign the bill of lading, which details what goods are being carried, and how much.
