Core Responsibilities

Primary Functions

Develop and maintain accurate demand forecasts for assigned categories by analyzing historical sales, market trends, promotions, seasonality and collaborative inputs from sales, marketing and merchandising to minimize out-of-stocks and excess inventory.
Execute end-to-end purchase order management: create, validate, issue, track and confirm POs in ERP systems (SAP, Oracle, NetSuite, Blue Yonder/JDA), ensuring on-time delivery and correct pricing, lead times and incoterms.
Build and maintain replenishment plans and safety stock policies using statistical models, vendor lead-time variability and service-level targets to optimize inventory turns and working capital.
Plan and manage promotional forecasting and inventory allocation for trade promotions and marketing campaigns, coordinating timing, quantities and distribution across channels to meet promotional demand without overstocking.
Own vendor performance management: monitor on-time delivery, fill rate, quality metrics, lead time adherence, and coordinate corrective actions with suppliers and operations.
Negotiate commercial terms, price, freight and lead time agreements with suppliers and logistics partners to reduce costs and improve supply reliability.
Partner with Category Management and Merchandising to align assortment changes, new product introductions (NPIs) and phase-outs with supply plans and sourcing strategies.
Drive weekly/monthly S&OP processes: provide data-driven demand inputs, review supply constraints, update inventory projections and recommend order revisions to leadership.
Monitor inventory health through metrics (turns, days of cover, aged inventory, slow-moving SKU analysis) and implement disposition strategies including markdowns, transfers, promotions or supplier returns.
Conduct root-cause analysis of forecast variance and supply disruption events; propose and implement corrective improvements to forecasting algorithms, demand inputs and supplier measures.
Maintain and reconcile master data for assigned SKUs: lead times, reorder points, safety stock, pack sizes, BOMs, item classifications and vendor assignments to ensure system accuracy.
Develop and deliver weekly and ad-hoc inventory, forecast and purchasing reports and dashboards for stakeholders using Excel, Power BI or Tableau to support decision-making.
Manage onboarding and qualification of new suppliers including sample review, compliance checks, capacity assessment and contractual terms to ensure supply continuity for NPIs.
Coordinate cross-functional launch plans for NPIs, ensuring procurement timelines, tooling/mfg lead-times and inventory buffers are set to support first sale.
Implement continuous improvement initiatives for purchasing and planning processes, including automation of PO creation, forecast smoothing, and cycle-count feedback loops.
Evaluate and select inventory replenishment strategies (min/max, EOQ, continuous review) by SKU class and channel, applying ABC/XYZ segmentation to prioritize focus and resources.
Escalate and manage supply chain disruptions (supplier delays, capacity shortages, logistics constraints), developing contingency plans such as alternative suppliers, freight changes, or allocation prioritization.
Prepare and present monthly review packages to commercial and finance stakeholders outlining forecast accuracy, inventory positions, P&L impact and recommended actions to achieve KPI targets.
Ensure compliance with procurement policies, import/export regulations, customs documentation and corporate governance standards for international sourcing and vendor contracts.
Collaborate with finance to model the working capital impact of purchasing decisions, identify inventory write-offs and drive cost-to-serve improvements.
Conduct competitor and market intelligence to identify sourcing opportunities, pricing pressures, and category trends that inform buying strategies.
Maintain strong cross-functional relationships (warehouse, logistics, quality, customer service) to ensure seamless order fulfillment and continuous improvement in supply reliability.
Coordinate cycle counts, stock audits and supplier reconciliations to verify inventory accuracy and drive accountability back to procurement and trading partners.
