    Talleres Barriga Sánchez TABSA experienced limitations in inventory control, reflected in incomplete records, discrepancies between physical and digital stock, limited traceability, and the absence of clearly defined replenishment parameters. The general objective of the research was to implement and evaluate an inventory control system at Talleres Barriga Sánchez TABSA, aimed at improving physical-digital accuracy, traceability, and replenishment compliance, with results measured through pre-intervention and post-intervention key performance indicators. The study adopted a mixed-methods approach with a quantitative emphasis, an applied research design, and a single-group pre-experimental pre-test/post-test structure. The participants comprised the manager and eight employees. The technical database included 21 coded inventory references with monthly records from January to September 2026, equivalent to 189 consumption records. Data were collected through an interview, questionnaire, direct observation, documentary review, physical stock count, physical-digital reconciliation, a FENIX functional checklist, and a KPI matrix. Ten paired items were used to assess inventory accuracy. The results showed favourable operational changes: physical-digital accuracy increased from 40% to 90%; average recording time decreased from 18 to 7 minutes; internal shortages fell from 12 to 4 cases; replenishment compliance increased from 45% to 82%; traceability rose from 30% to 85%. The exact two-sided McNemar test yielded p = 0.0625; therefore, the improvement in accuracy was interpreted as descriptive rather than statistically conclusive at the 5% significance level. Overall, the system strengthened inventory control, traceability, and operational monitoring at TABSA.
