The invention relates to the field of electronic automatic account checking technology, and particularly to a marketing/finance integration electricity charge account checking system which is suitable for electricity charge collection. The marketing/finance integration electricity charge account checking system is characterized by comprising the components of a real-time transfer arrival data receiving unit which is used for receiving bank real-time transfer arrival information and outputting the transfer arrival information, a transfer arrival confirmation unit which is used for confirming the transfer arrival information, a local account checking information acquiring unit which is used for acquiring a local account checking file, a bank account checking data acquiring unit which is used for acquiring bank fixed-time account checking data, an account checking unit which is used for matching data output from an account checking information generating unit with bank account checking information that is received by an account checking data receiving unit, and a display unit which is used for displaying a result output from the account checking unit. Compared with the prior art, the marketing/finance integration electricity charge account checking system has advantages of effectively shortening transfer arrival time in electricity charge collection, ensuring in-time enough-amount handover of enterprise electricity charge, increasing fund returning speed of the enterprise, and reducing load cost.
