Open-end credit refers to a type of credit that allows a borrower to make purchases on credit up to a predetermined credit limit. This type of credit is also commonly referred to as a revolving credit or a line of credit. Some other synonyms for open-end credit include revolving credit account, charge account, and credit line. These terms all refer to the same type of credit, where a borrower can borrow up to a limit, pay it back, then borrow again. This flexibility allows for the borrower to use the credit as needed and have the ability to continue to borrow as long as they make timely payments on their account.
