"Buying every SKU at the same MOQ—that's not your strategy. That's a vendor constraint." [03:57]
Most product founders think hitting MOQ on every item is the safest path. But Mary Wiegand, who spent 10+ years managing inventory at Target, Tiffany & Co., and Victoria's Secret, reveals why this approach creates lumpy inventory and cash flow problems. In this episode, she breaks down the three lead times you're probably missing, the safety stock formula that prevents panic orders, and why tracking revenue instead of unit velocity is costing you money. If you've ever run out of stock during a promotion or air-freighted inventory because you miscalculated timing, this conversation will change how you plan.
