On-Time Delivery Rate OTD

COO VP Operations CFO

On-Time Delivery Rate (OTD) measures the percentage of orders or projects delivered to customers by the committed delivery date. It is a primary supply chain and operations quality metric that directly affects customer satisfaction, repeat purchase behavior, and SLA compliance. High OTD requires coordination across procurement, manufacturing (or fulfillment), logistics, and customer communication.

OTD should be tracked separately for customer-committed dates vs. internal target dates; the customer-committed OTD is the metric that directly affects satisfaction and SLA compliance.

Formula

Orders Delivered On or Before Committed Date ÷ Total Orders Delivered × 100

NetSuiteOrder management and OTD reporting
SAPSupply chain OTD analytics for enterprise manufacturers

What Drives It

Inventory availability at time of order (stockout rate)
Fulfillment center processing speed and capacity
Carrier reliability and last-mile delivery performance
Demand forecasting accuracy preventing out-of-stock delays
Order management system efficiency and automation

Causal Analysis: Carrier performance analysis identifies which shipping partners cause the most OTD failures, enabling data-driven carrier selection and routing decisions.

Benchmark

Best-in-class e-commerce OTD targets 95%+; B2B supply chain typically targets 90%+; below 85% consistently causes significant customer satisfaction and churn risk.

Common Mistake

Measuring OTD at the shipping-out date rather than customer delivery date, which counts late deliveries as on-time if they left the warehouse on schedule.

How different roles think about this metric

Each function reads OTD through a different lens and takes different actions when it changes.

COO

The COO monitors OTD as a primary supply chain performance metric and coordinates across fulfillment, logistics, and procurement to maintain target rates.

VP Operations

VP Operations drills into OTD failures by root cause (stockout, carrier delay, fulfillment error) to prioritize supply chain improvement investments.

CFO

The CFO monitors OTD because persistent failures generate customer compensation costs, return rates, and churn that directly affect revenue and margin.

Common Questions About On-Time Delivery Rate

Click any question to expand the answer.

How should OTD be calculated when delivery dates span across a month?

Calculate OTD as the percentage of orders due in the period that were delivered on or before their committed date. Measure at the customer-promised delivery date, not the internal processing or shipping target. Include orders with customer-rescheduled dates in the calculation but flag them separately to distinguish voluntary rescheduling from operational delays.

What is the difference between OTD and fulfillment rate?

OTD measures whether orders are delivered when promised. Fulfillment rate measures whether orders can be shipped at all (i.e., whether the item is in stock and can be fulfilled). An order can be fulfilled (item in stock, shipped) but not delivered on time (carrier delay). Tracking both metrics together reveals whether delivery failures are upstream (inventory, fulfillment) or downstream (shipping and logistics) issues.

How does carrier performance affect OTD?

Last-mile carrier reliability is a significant driver of OTD for businesses using third-party logistics. Carrier on-time performance varies by region, service level, and season. Businesses should track OTD by carrier to identify which partners have the worst performance, negotiate performance SLAs into carrier contracts, and maintain backup carrier options for critical delivery windows.

How can I improve OTD without increasing logistics costs?

Improve demand forecasting to reduce stockouts that cause order delays. Optimize fulfillment center processes to reduce processing time between order receipt and shipment. Implement intelligent order routing that assigns orders to the fulfillment location closest to the customer with available inventory. Use carrier selection algorithms that optimize for reliability and delivery date probability rather than just cost.
