This study aims to analyze the Puig Brasil accounts payable process and establish its current levels of efficiency and effectiveness, and then propose changes to optimize it. The focus of the study was the theories of renowned authors in the field of management that address relevant issues when related to the management of organizational processes. The survey was conducted through a qualitative approach, through in-depth interviews with people using the process on a regular basis at different hierarchical levels, in order to show all the process perceptions. The groups were divided into: process operators, internal customers and external customers (suppliers). Particular problems were identified in three stages of the process. In the planning stage flaws have been found in the staff preparation for the use of the tool that supports the process. When it comes to implementation, we can highlight problems in the flow of information within the process. In control step, underscores the lack of indicators to measure final results.
