The main purpose of the credit guarantee services is to enable promising Small and Medium-sized Enterprises (SMEs) without enough collateral to obtain funds and make smooth headway in the financial or business transaction. In an attempt to meet SMEs' demand for financing service, Korea Credit Guarantee Fund provides enterprises with credit guarantee services for the repayment of liabilities assumed by business enterprises in transactions with other companies or institutions.

By doing so, the credit guarantee services facilitate the financing of SMEs through the credit guarantees and stimulate the sound credit transaction through the efficient management of credit information.

Credit guarantee services involve a series of interactions among three parties: the guarantor (KODIT), the debtor (enterprises), and the creditor (financial institutions). If the debtor defaults, KODIT pays the guarantee obligation to financial institutions in place of the debtor.
