On-Time Delivery Metrics

Overview

The On-Time Delivery metric helps you keep track of how accurate your delivery time estimations are and whether or not your deliveries are getting to their destination on time. It is important that packages arrive on time, as late deliveries negatively affect customer loyalty and can cause you to lose business.

This e-commerce metric is crucial for e-commerce businesses, as it helps them evaluate the efficiency of their order fulfillment process, shipping partners, and overall customer satisfaction.

Why this KPI matters

Fast shipping is table stakes. Reliable shipping wins loyalty. On-time delivery protects margins by cutting reships, refunds, and support contacts. It also feeds your review score and repeat purchase rate.

How to calculate it correctly

1. Define on-time. Delivered by the promised date or within the promised window.
2. Use shipment-level data. Count packages or orders, then flag each as on-time or late.
3. Compute the share. Divide on-time shipments by total shipments for the period.

Data you need

• Ship date, promised date, delivered date, carrier, service level
• Order ID and destination region
• Exception codes for delays

Improve on-time delivery

• Set honest promises. Tighten your promise logic by region and service level. Pad peak periods.
• Clean pick-pack workflow. Slot fast movers near packing, use scan checks, and measure pick time.
• Carrier performance reviews. Compare carriers by lane. Shift volume to the most reliable ones.
• Proactive comms. Send delay alerts early with clear new ETAs and easy refunds where needed.

Track on-time delivery in Klips

1. Connect systems. Bring in data from your OMS/WMS and carrier tracking feeds.
2. Create calculations. Compute on-time flags, late reasons, and average days late.
3. Visualize. A gauge for current on-time rate, a heatmap by region, and a trend line by week give a fast read.
4. Set thresholds. Colour rules flag lanes below target. Add notes for weather or peak events.
5. Share. Send a daily snapshot to operations and support managers.

Common pitfalls

• Over-promising in checkout. Conversion goes up, reviews go down. Tune promises to your true performance.
• Not separating controllable vs uncontrollable delays. Track both and fix what you control first.
• Ignoring partials. Split shipments can hide lateness. Measure at the line or package level.
