Credit was the act of lending money to a person until they could pay it back.
After he ran out of money, Kozak wanted to buy more bloodwine with credit, something which Quark was not open to, as his bar was not as profitable as it had been at the time. (DS9: "The House of Quark")
In 2372, Quark told Morn not to extend any lines of credit while the Lurian was temporarily running the bar. (DS9: "Little Green Men")
By the end of the year, Quark had begun to give his customers credit, something which Brunt criticized him for. (DS9: "Body Parts")
