A warehouse dashboard says orders are flowing. The receiving dock has a different opinion. Fulfillment is a chain of handoffs: providers take on tasks, inbound stock is checked and stored, order lines are picked and packed, and parcels meet a carrier cutoff. One vague word can hide three different costs or a queue that nobody owns. This guide follows inventory from the supplier dock to outbound dispatch, then connects speed and accuracy to the operating choices behind them. Use each metric with its start event, end event and service scope written down.

📎 How to read this page
What it means gives the precise meaning. Operator translation gives the version you might hear in a real ecommerce meeting. In real life shows an illustrative example. Watch out and the confusion boxes show where a familiar term can mislead.
📈 Read the relationships first
These combinations are diagnostic hypotheses, not proof of causality. Compare the same period and scope, then investigate the mechanism.
🚚 Receiving up + dock-to-stock time up
Usually means: Inbound volume or exceptions may exceed receiving and putaway capacity. Check next: appointment timing, discrepancy rates and labor by shift.
📦 Orders picked up + order accuracy down
Usually means: Higher throughput may be outrunning verification or creating tote-sort errors. Check next: SKU scans, batch separation and substitutions.
⏱️ Same-day dispatch up + missed cutoff up
Usually means: The order promise or workload is misaligned with pickup capacity. Check next: order eligibility, local time zones and carrier collection windows.
🏭 Inventory spread across nodes + split shipments up
Usually means: Stock placement and routing may not match basket demand. Check next: SKU-level availability, order routing and cost per shipped parcel.

🔀 3PL vs 4PL
A 3PL performs contracted logistics tasks. A 4PL usually coordinates providers or a wider logistics network. Names vary; compare the actual scope and accountability in the contract.
🔀 Cross-docking vs putaway
Cross-docking routes inbound goods toward outbound dispatch with little storage. Putaway assigns received stock to a storage location for later use.
🔀 Batch picking vs wave picking
Batch picking combines orders into a shared picking trip. Wave picking releases a planned set of work; a wave can use several picking methods.
🔀 Fulfillment vs shipping vs delivery
Fulfillment covers warehouse processing and dispatch. Shipping covers carrier movement. Delivery is the parcel's arrival outcome; keep measures in their own scope.
