Factoring
In terms of e-commerce, factoring is the practice of allowing other companies to process credit card transactions through one company's merchant account rather than requiring them to purchase a merchant account of their own, in exchange for a percentage of the transaction. This is also known as credit card laundering, and is illegal practice that can result in heavy fines.

Floor Limit
A specific dollar limit which designates that certain transactions must be authorized. For instance, if your floor limit is $1,500, authorization is required for any transaction over that amount.
