To maximize margins, analyze the Total Cost of Ownership (TCO), including fabric costs, CMT (Cut, Make, Trim) labor, and logistics. Bulk discounts usually trigger at 500-1,000 units per style, potentially reducing unit costs by 15-25%. Consider fabric pooling (using the same fabric for different designs) to meet Minimum Order Quantities (MOQ) for custom dyeing. Also, evaluate the trade-off between FOB (Free On Board) and DDP (Delivered Duty Paid) to manage your shipping risks and costs effectively.
