Plan de mejora para el proceso de facturación del centro administrativo documental (CAD) de Interaseo S.A.S. E.S.P.

Abstract

This report presents an improvement plan developed based on my professional internship at the Administrative Documentation Center (CAD)—a unit within the Shared Services Department of Interaseo S.A.S. E.S.P.—carried out between March 4 and September 3, 2026, as a requirement for the International Business program at Santo Tomás University (Medellín campus). Over the course of six months, I processed various types of domestic and international invoices and performed supplier reconciliations. A SWOT analysis of the area revealed a key weakness: the invoicing process relied on manual steps spread across multiple tools, resulting in long processing times relative to the daily invoice volume. Addressing this weakness and the threat of potential operational delays, I proposed a process automation plan; its implementation—led by the CAD specialist—reduced the processing time per invoice from five to four minutes. The report describes the company, the formulation of the improvement plan, the proposal and its results, and the monitoring conducted throughout the four cycles of the internship.
