T This final project report discusses the audit procedures for the estimation of the allowance for impairment losses on trade receivables conducted by kap haf for its client (pt wwi). the background of this study is driven by the importance of executing audit procedures on the estimation of allowance for impairment losses on trade receivables in accordance with applicable auditing standards. this ensures that the allowance balance is fairly stated and reflects the true economic condition of the company, considering the high uncertainty inherent in estimating the allowance for impairment losses on trade receivables. this report was compiled based on the field internship experience at kap haf, using data collection techniques such as direct observation through active participation in the audit process of trade receivables and the estimation of allowance for impairment losses on trade receivables, interviews with the engagement team and client management, as well as the review of supporting documents and reference materials. the analysis results indicate that, in general, kap haf has executed the audit procedures for the estimation of allowance for impairment losses on trade receivables based on the auditing standard sa 540 (revised 2021). however, the risk identification and assessment phase was not fully compliant with the procedures prescribed in sa 540 (revised 2021). kap haf did not perform the assessment of inherent risk and control risk separately, which is a mandatory procedure under sa 540 (revised 2021). risk identification and assessment regarding the estimation of the allowance for impairment losses on trade receivables need to be properly executed so that professional judgments and assessments of management bias have a more robust foundation.
