Design and Implementation of an Automated CFDI Analysis Algorithm for Accounting and Tax Optimization in SMEs

This study aimed to develop and evaluate an algorithm designed to reduce the time required for the analysis of Digital Tax Receipts (CFDI), with application to small and medium-sized enterprises (SMEs). Using a mixed and experimental approach, the performance of the algorithm was compared with manual review conducted by 170 Financial Engineering students. The results indicated that the algorithm was significantly more efficient, achieving an average reduction of 220.14 seconds and a very large effect size (Cohen’s d = 3.77). Furthermore, the algorithm achieved an effectiveness rate of 88% in determining the validity of CFDIs with respect to their deductibility for tax purposes, thereby highlighting its potential to optimise processes, improve productivity, and support decision-making in accounting and organisational contexts.
