The invention proposes an improvement for a method for collecting a debt. The method includes entering in a data processing system data at least including data concerning the debtor and the debt, permitting debt access to at least two parties to at least a part of the data entered in the system, and initiating an action for collecting the debt on a basis of the data entered in the database. The improvement comprises entering accounting data regarding accounts payable to the creditor and payments to the creditor into the system, enabling a financing party providing a loan to the creditor on the payable accounts to inspect at least a part of the accounting data for determining an amount of the loan based on at least the part of the accounting data.
