T This internship was conducted at an international shipping company that provides intermodal services as part of its integrated logistics solutions. the purpose of the internship was to gain an understanding of the intermodal business process, identify issues related to the management of purchase orders (pos) and vendor invoices, and propose recommendations to improve the existing process.the methodology used in this report consisted of direct observation, participation in intermodal administrative activities, and analysis of documents and systems utilized by the company. the study focused on the vendor invoice management process involving job orders (jos), purchase orders (pos), the invoice upload system, and the verification procedures performed by the accounts payable (ap) department.the analysis identified four main issues: delays in po creation, invoice submissions without po numbers, the manual linking process between pos and invoices, and incomplete or inconsistent transaction data. these issues negatively affected operational efficiency, increased the risk of errors, delayed vendor payments, and reduced the quality of financial reporting.to address these challenges, several recommendations were proposed, including the automation of po creation, the implementation of po numbers as a mandatory field in the invoice upload system, the development of an auto-linking feature between pos and invoices, the enhancement of data quality through regular monitoring activities, and the strengthening of existing standard operating procedures (sops). the implementation of these recommendations is expected to improve effectiveness, operational efficiency, and internal control quality in the management of intermodal services.
