<![CDATA[Twenty2 Clothing Store is a fashion business experiencing difficulties in inventory control due to demand uncertainty.

The reorder point for June 2025-January 2026 was 131 pcs, for February-March 2026 was 134 pcs, and for April-May 2026 was 38 pcs. The recommended optimal order quantity for June 2025-January 2026 was 396 pieces, for February-March 2026 was 176 pieces, and for April-May 2026 was 28 pieces. The analysis of inventory management internal control according to COSO control components at Twenty2 Clothing Store was good but still simple and not yet digitalized.
