Levels 1 and 2 are fairly easy to achieve. Level 1 only requires standard transaction details such as date and amount, and can be achieved through any processing method. Level 2 includes the same details plus the addition of sales tax.
In order to achieve Level 3, there are nearly twenty fields of line-item data that must be sent along with the transaction, including: invoice number, PO number, freight amount, item commodity code, unit of measure, tax detail, and many more.
Level 3 pricing is available for purchasing, corporate and government spending accounts (GSA). Businesses who wish to receive Level 3 must send all line-item data and transaction information to the card-issuing bank.
