This study takes 17 414 panel data of Chinese A-share listed companies from 2010 to 2020 as a sample to explore the function mechanism of customers' information technology ability on audit pricing. The empirical results reveal that for state-owned enterprises, customers' information technology capability negatively affects audit pricing, but for non-state-owned enterprises, it affects positively. Compared with local small-scale accounting firms, international "Top Four" accountants firms can better adapt to the growth of customers' capabilities, and the positive correlation between the two is not significant. The positive effect of the capability on audit pricing is mainly reflected in the period after the audit price limit and in smaller companies.
