What is On Time In Full (OTIF)?

If you own or manage a transportation company and are hearing about this for the first time, you’re probably wondering: “What is OTIF?” and “Why should my business care about it?”

OTIF, or On Time In Full (OTIF), is a delivery performance metric used in supply chains. It’s measured into two distinct halves. The first half, On Time, means that the driver arrived precisely as scheduled, corresponding closely with the established ETA window.

The second half, In Full, means that every item in an order was delivered and accepted by a customer. Simply put, the exact quantity ordered matches what was ultimately delivered.

While this measurement tool may seem unwieldy at first, it’s extremely easy to understand and apply. And once you grasp what OTIF (or DIFOT) is, you’ll be able to use it to improve virtually every aspect of your shipping process as well as customer satisfaction.

What is OTIF and How Does it Impact Your Supply Chain Operations?

OTIF (sometimes called DIFOT) is a key performance indicator (KPI) used in supply chain management. It assesses whether customer orders were successfully delivered on the promised date and in the correct quantity and condition.

Your business can use whichever acronym makes more sense to you and your team. Regardless of which one you choose, you’ll use it to better understand how well your supply chain functions and where you can improve your operation.


OTIF is often used interchangeably with DIFOT, which stands for Delivered in Full On Time. There is no difference between these two and logistics operators can use either one as their main KPI.

OTIF Calculation: Measuring OTIF Performance

DIFOT is calculated in a very simple way that any business can use to determine the efficiency of their supply chain operations.

Here’s how:

▶️ Identify whether items in a given order are Delivered, Not Delivered, or Partially Delivered. By using a Delivery Management Software like TransVirtual, your business can track items at every single point of the delivery process and ensure they reach their destination. Then, you’ll be able to determine the exact percentage of items delivered in full over time.

▶️ Determine whether the items in the order were delivered on time. Since this is decided mostly by the logistics manager, it may be more difficult to pin down. Most of the time, that ETA falls within a 90-minute window. Fortunately, with quality transportation management software, you can set a specific time window for the ETA and learn the percentage of deliveries made within that window.

▶️ Calculate the percentage of items delivered in full and on time over a given period. For example, if 95 out of 100 items were delivered in full and on time on a given day, you have a 95% DIFOT.

OTIF/DIFOT software can provide highly accurate reports that allow you to easily parse the data and understand any issues you may have in your supply chain.

Why is OTIF One of the Most Important Supply Chain Metrics?

OTIF is a critical key performance indicator (KPI) because it accurately defines supply chain efficiency with more nuance than other indicators. The higher your OTIF/DIFOT score, the more demonstrably successful you are at taking orders, procuring freight, communicating with suppliers, and transporting the cargo itself.

Most businesses in the transportation industry consider OTIF a better performance indicating metric than less comprehensive alternatives like shipped-on-time (SOT), on time delivery, or on-time performance (OTP). DIFOT looks at deliveries from a better perspective altogether – that of the customer.

In other words, if your business can present itself as having a higher OTIF scores than your competitors, potential customers will see that as an indicator of your commitment to efficiency and excellence.

How to Improve DIFOT Performance (or OTIF Scores)

Once you calculate OTIF, you can then thoroughly examine the data you’ve collected. For example, if only a few of your deliveries had issues, you can probably assume the errors were due to human error or carrier failure.

The majority of factors that impact your OTIF metrics are related to shipping routes and incorrect assumptions about established transit times. But if you see multiple delivery issues with the same customer, it’s likely a systemic problem that can be corrected and prevented in the future.

With the right monitoring tools on your side, you should be able to pinpoint transit issues when they occur and why. By fixing them, you’ll see an increase in your overall DIFOT performance. These include optimal cargo loading, perfected route navigation, utilizing contactless delivery options, and much more.
