PURPOSE: An integrated donation system is provided to enable a consumer to consistently donate through consistent consumption unless the consumer changes a fixed direct recommendation code or a fixed indirect recommendation code. CONSTITUTION: If a management code of a consumer is inputted and a product purchase history is inputted, a selling server(30) transmits the inputted information to a donation server(50) through a communication network(40). The donation server extracts a direct recommendation code or an indirect recommendation code through the management code. The donation server fixes the amount of a donation by extracting a preset share from the amount of transaction money according to the product purchase history. The donation server automatically transfers the donation to a recipient account.
