The invention provides a method for designing a group financial incorporation system based on real-time account incorporation. In the financial management field, the group faces trouble when issuing the financial report of the entire group, even though a financial management information system is applied, the old way of manual operation is continuously used, namely, each subordinate unit keeps accounts, formulates the statement and reports the statement to the group company, and then the group company summarizes the statements, calculates elimination entry and carries out incorporation treatment, finally the incorporated financial report of the entire group is shaped. The entire process flow features multiple links, long period, complex steps and low accuracy and can not satisfy the requirement of the current management of the group company. In the financial management information field, the method adopts a creative way, namely account incorporation treatment, when the group financial report is issued, adopts the way of directly incorporating the subject balance accounts of the subordinate units to directly form the financial situation report of the entire group, thus simplifying the flows and witnessing more rapid and effective realization.
