CEO Executive AssistantInventory Control: The Function That Determines Margin
Inventory management is one of the most financially consequential functions in ecommerce. Too little inventory means stockouts, missed sales, and frustrated customers. Too much inventory means working capital tied up in slow-moving stock, markdown risk, and warehouse cost. Getting inventory right requires sophisticated planning, reliable supplier data, demand forecasting accuracy, and responsive operational processes.
All of this is a specialized professional function that the CEO should not be managing personally. Yet many ecommerce CEOs, particularly those with merchandising or operations backgrounds, stay deeply involved in inventory decisions: reviewing purchase orders, questioning reorder quantities, and getting pulled into individual SKU conversations. This involvement creates bottlenecks without improving outcomes.
The CEO’s Inventory Control Role
The CEO’s appropriate involvement in inventory:
Inventory investment policy: The overall level of inventory investment (targeted weeks of supply, maximum inventory as a percentage of revenue) is a financial policy decision that affects working capital. The CEO sets this policy with the CFO.
Inventory risk tolerance: The policy for how much excess inventory is acceptable and at what point markdowns should be taken is a margin management decision that reflects the business’s brand positioning and financial strategy.
Strategic category investments: When entering a new category or backing a major product launch with deep initial inventory, this is a strategic capital allocation decision.
Major write-off approvals: Significant inventory write-offs (above a defined financial threshold) require CEO and CFO approval.
All other inventory decisions, including SKU-level reorder decisions, safety stock levels, days of supply targets by category, and the management of slow-moving inventory, belong to the inventory management team.
Building the Inventory Control Team
The inventory function should include:
Head of Inventory Management or Supply Chain Planning: Owns the inventory policy implementation, demand forecasting, purchase order management, and the team that executes day-to-day inventory management.
Inventory Planners: Manage SKU-level demand forecasting, reorder calculations, and purchase order creation. Each planner typically owns a category or supplier group.
Demand Forecasting Analyst: Develops and maintains the statistical demand forecasting models that inform inventory planning, incorporating historical sales data, promotional calendars, and seasonal patterns.
Inventory Operations Coordinator: Manages the purchase order workflow, supplier communication, inbound shipment tracking, and receiving coordination.
The Inventory Management System
Effective inventory delegation requires the right technology. An inventory management system (IMS) or a supply chain planning tool connected to the OMS and the ecommerce platform gives the inventory team the data they need to make accurate reorder decisions without CEO input.
The inventory system should:
- Track current stock levels by SKU and location in real time
- Calculate days of supply based on current velocity
- Generate reorder recommendations when SKUs approach the reorder point
- Track inbound purchase orders and expected receipt dates
With this system in place, the inventory team makes reorder decisions based on data-driven recommendations rather than manual analysis or CEO direction.
Inventory Metrics for CEO Oversight
The CEO monitors inventory health through a monthly report covering:
- Inventory turns: Total COGS divided by average inventory value. Higher turns indicate more efficient inventory use.
- Days of supply: Average days of supply across the active SKU base. Should be within the policy range set by the CEO.
- Stockout rate: The percentage of active SKUs that experienced a stockout in the period. Stockouts directly represent lost revenue.
- Excess inventory value: The value of inventory exceeding a defined excess threshold. A leading indicator of potential markdown needs.
- Inventory write-off: Any inventory written off in the period and the reason.
These metrics give the CEO a clear view of inventory health without reviewing individual SKU reports.
Reducing Inventory Risk Through Supplier Collaboration
One effective strategy for improving inventory performance is closer supplier collaboration. Sharing demand forecasts and inventory data with key suppliers enables them to plan their own production more accurately and reduces lead time variability, which directly improves inventory planning accuracy.
The inventory team, in collaboration with the procurement function, should manage supplier collaboration programs. The CEO may have executive-level conversations with major supplier executives about supply chain partnership, but the operational work of supplier data sharing and collaborative forecasting belongs to the inventory and procurement teams.

Conclusion
Inventory control is a discipline that rewards professionalization. CEOs who invest in capable inventory leadership, the right technology, and a clear inventory policy framework will find that their inventory performance improves and that they spend almost no time on inventory decisions. The CEO’s role is to set the financial guardrails and the strategic priorities, then trust the inventory team to manage within those parameters.
