Do ISAs fulfil their aim in the audit of SMEs? : A study concerning how the implementation of ISAs in Sweden has affected audit quality and efficiency in the audit of small and medium-sized enterprises

Previous research noticed a conflict between audit quality and efficiency that has been discussed when applying International Standards on Auditing (ISAs) in the audit of small and medium-sized enterprises (SMEs). However, there is a lack of research that concerns ISAs affect on audit quality and efficiency in the same study. Hence, the following research question was formulated: How has the implementation of International Standards on Auditing in Sweden affected audit quality and efficiency in the audit of small and medium-sized enterprises? Based on the perceptions of the interviewees, the implementation of ISAs has resulted in clearer risk assessment and increased use of analytical procedures, thereby improved audit quality. Further, ISAs have increased the hours spent on internal control, which impair audit efficiency since this activity is not judged as important when gathering audit evidence. This conflict between audit quality and efficiency is mostly explained by the shall requirements of ISAs since many of these are not applicable in the audit of SMEs. Our findings indicate a need to adapt ISAs and to allow deviations from shall requirements. The outcome would be that ISAs are closer to fulfil their aim in the audit of SMEs, which is higher audit quality without the loss of efficiency.
