The invention discloses a network payment accounting affair processing system and method based on the Internet of Things. The internet-of-things-based network payment accounting transaction processing system comprises an ordering module, a main control module, an internet-of-things communication module, an order information statistics module, a payment module, an expenditure and income accounting module, a financial statement generation module, an accounting information storage module and a display module. The IoT equipment is used for preferentially detecting the IoT gateway through the IoT communication module, and if the IoT gateway is found, the authentication information of the IoT equipment accessing the IoT platform can be obtained while the IoT gateway is accessed to the IoT platform. And the hidden danger that the IoT equipment cannot normally access the IoT platform when the IoT gateway sends a fault is effectively prevented. The reliability of the network is effectively improved. And meanwhile, the user can be more conveniently assisted to complete payment through the payment module, so that the payment efficiency is improved.
