overstocking

Overstocking refers to holding more inventory than is necessary to meet expected demand. It increases carrying costs and elevates the risk of obsolescence or spoilage, tying up capital and occupying storage space. Overstock can result from forecasting errors, aggressive promotions, bulk purchasing, supplier lead times, or seasonality.

Causes of overstocking include demand variability and misaligned forecasts, overestimation of future sales, changes in consumer preferences, promotions or price guarantees, bulk ordering to secure discounts, supply chain disruptions, and the accumulation of returns that have not yet been resold.

Consequences comprise higher holding costs such as storage, insurance, depreciation, and obsolescence; markdowns or write-downs to clear excess stock; cash flow strain and reduced profitability; potential space constraints that crowd out newer or faster-moving items; and the risk of expiry for perishable goods.

Management and mitigation strategies focus on inventory optimization and disciplined forecasting. Techniques include ABC analysis to classify items by value and turnover, safety stock optimization, accurate demand planning, and regular inventory audits. Approaches such as just-in-time or vendor-managed inventory, better supplier collaboration, dynamic pricing, product lifecycle management, and targeted clearance of excess stock can help reduce overstock.

Sector considerations vary by context. Retailers often face overstock with seasonal or fashion items, while manufacturers contend with raw materials or finished goods inventories. In healthcare and food, spoilage, expiry, and regulatory constraints heighten the costs of excess stock, making efficient inventory control particularly important in these sectors.
