StockSync is a PO optimization engine for boutique multi-store apparel retailers that recommends reorder quantities, timing, and payment splits to minimize cash tie-up while meeting demand. It blends historical sell-through, seasonality, lead-times and vendor payment options to generate optimized POs and suggested negotiation scripts. Target users are inventory managers and operations leads at mid-market fashion retailers who want to increase turnover and reduce working capital. The product ships as a replenishment assistant with actionable POs and a/b-tested reorder rules.
