Episode 46: The Inventory Strategy That Saves Founders $10K+


Listen Later

"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.

  • The three lead times you must track: fabric, production, and transit [09:35]

  • Why unit velocity per SKU matters more than total revenue [10:49]
  • How to track trends using the last 2-4 weeks of sales data [10:49]
  • The marketing inputs that affect demand: ads, influencers, events [11:59]
  • Why carrying promotional spikes forward destroys cash flow [16:50]
  • How to adjust size curves based on actual sales (not assumptions) [22:31]
  • Why tank tops sold smaller sizes than other styles—and what that reveals [22:31]
  • When it's okay to consciously choose an out-of-stock period [08:50]
  • The replenishment log that tells you when to reorder before you run out [30:21]
