Order Fulfillment
Definition
Order fulfillment is the end-to-end process of receiving a customer order and delivering it: order capture, allocation, picking, packing, shipping, and confirmation. It is where supply chain performance becomes visible to the customer.
In Practice
Fulfillment starts the moment an order arrives: the system checks credit and inventory, allocates stock, and routes the order to a warehouse. There it is picked, packed, labeled, and handed to a carrier, with tracking pushed back to the customer. Each step has a cycle-time and accuracy target, and the weakest step sets the customer experience.
Planners care about fulfillment because upstream decisions determine its ceiling. If inventory is positioned in the wrong region, no amount of warehouse hustle delivers next-day. Allocation rules also embed strategy: when stock is short, do you serve the largest customer, the earliest order, or the highest-margin channel? Those rules deserve deliberate design, not defaults.
E-commerce has raised the bar dramatically. A retailer promising next-day delivery must complete picking and packing within hours of order cutoff, which drives choices about DC locations, labor shifts, carrier pickups, and how much inventory to forward-deploy.

A perfect order is one delivered complete, on time, damage-free, and with accurate documentation. The perfect order rate multiplies these components together, making it one of the most demanding measures of fulfillment quality.
Service LevelThe target probability of not stocking out during a replenishment cycle, or more broadly the standard of product availability promised to customers. It is the key input for sizing safety stock.
BackorderA customer order, or portion of one, accepted for fulfillment despite the item being out of stock, to be shipped when inventory becomes available. Managing backorders means tracking, prioritizing, and clearing this unmet demand.
StockoutA stockout occurs when inventory of an item is exhausted and demand cannot be met from available stock. It results in lost sales, backorders, expediting costs, and eroded customer trust.
