OTIF On Time In Full Explained

Definition, Formula, & Benchmark

What's Keeping Your Customers Waiting?

DIFOT (Delivery In Full On Time) is Australia's preferred term for what globally is known as OTIF on-time in full – the critical supply chain metric that separates thriving businesses from those struggling with customer dissatisfaction and operational inefficiencies. 

Picture this: A customer places an order, eagerly anticipating its arrival, only to receive an incomplete shipment three days late. The frustration is palpable, the trust eroded, and the likelihood of repeat business diminished. This scenario plays out countless times across supply chains worldwide, highlighting the critical importance of delivering orders correctly and punctually.

In today's competitive marketplace, customer satisfaction hinges on one fundamental promise: delivering exactly what was ordered when it was promised. This is where DIFOT (or OTIF globally) becomes the ultimate measure of supply chain excellence.

Whether you're managing logistics operations, overseeing supply chain processes, or striving to improve supply chain visibility, understanding and optimising your OTIF performance can transform your business from struggling with customer dissatisfaction to achieving operational excellence that drives customer loyalty and business growth.

What is OTIF and Why Should You Care?

Improve Supply Chain Visibility

OTIF on time in full is a critical supply chain metric that measures a supplier's ability to deliver complete orders within agreed timeframes. This comprehensive measure evaluates two essential components: temporal accuracy (delivering on time) and quantity accuracy (delivering in full). The concept gained prominence. Walmart formalised OTIF as a mandatory supplier KPI in 2017 as a key performance indicator to track supplier performance, drive operational improvements, and increase customer satisfaction across its entire supply chain.

The significance of time in full OTIF extends far beyond simple delivery tracking. It serves as a barometer for supply chain operations effectiveness, revealing how well your supply chain management systems coordinate to meet customer demand. When you measure OTIF consistently, you're essentially evaluating your organisation's reliability in fulfilling delivery promises, which directly impacts customer satisfaction and long-term business performance.

This supply chain metric has become increasingly vital as market demands continue to evolve. Customers expect not just competitive pricing but also reliable service that consistently delivers on-time deliveries without compromising on order completeness. The beauty of OTIF lies in its simplicity and comprehensiveness - it provides a holistic view of your supplier's ability to meet commitments, encompassing everything from raw materials procurement to final delivery across your entire supply chain.

Calculate OTIF: Breaking Down the Numbers That Matter

Understanding the OTIF On Time in Full Calculation & Formula

To calculate OTIF effectively, you need to understand the fundamental formula that drives this crucial measurement. The OTIF formula is straightforward yet powerful:

OTIF Rate = (Total deliveries made on time and in full / Total deliveries made) × 100

For example, if your company processes 800 orders in a month and 680 arrive at the correct location within the confirmed delivery time, containing all requested items, your OTIF rate would be (680/800) × 100 = 85%.

However, calculating OTIF isn't always as simple as it appears. The challenge lies in defining what constitutes "on time" and "in full." Different retailers and supply chain partnerships may have varying interpretations - some consider delivery within a specific delivery window acceptable, while others require delivery on the exact confirmed delivery time. This lack of a standard OTIF definition creates complexity in supply chain management as manufacturers struggle to meet diverse retailer requirements.

The timing component requires careful consideration of lead time expectations and delivery delays, while factors such as supply chain disruptions and logistics challenges can significantly impact your ability to maintain consistent on-time deliveries. Similarly, the "in full" component depends on accurate inventory management, efficient warehouse management systems, and robust supply chain visibility to ensure complete order fulfilment without compromising your OTIF calculated results.

Good OTIF Benchmark: Setting Realistic Performance Targets

Establishing Standards for Good OTIF Score and Performance

In Australia, a DIFOT above 95 per cent is generally expected, while world-class performers aim for 97-99 per cent. Although 100 per cent perfection is the ideal, real-world supply chains face variables—long distances, sparse population centres and extreme weather - that make lead-time adherence the main OTIF failure mode.

Walmart’s programme illustrates how benchmarks evolve: the US retailer raised its supplier threshold from 75 per cent in 2017 to 98 per cent today, backed by a 3 per cent cost-of-goods penalty for non-compliance.

Illustrative OTIF/DIFOT targets by ABC inventory class

(actual targets are always contract-specific)

• Class A (high-value / high-volume): 97–99 %
• Class B: 92–96 %
• Class C (low-value / long-tail): 80–90 %

The financial stakes are significant: a 2019 McKinsey study on OTIF in the consumer sector estimated US $5-6 billion in annual OTIF penalties across the US consumer-packaged-goods sector. Australian retailers do not yet levy OTIF-specific charge-backs, but the upcoming Supplier Protection Code enables fines of up to A$10 million for wider supply-chain breaches.

Regional variations - network infrastructure, regulations and customer expectations - mean each business should calibrate “good” OTIF against its own lane lengths, partner SLAs and cost-to-serve economics.

The Hidden Costs of Low OTIF Scores

Beyond Numbers: Real Business Impact on Inventory Levels

Low OTIF scores create ripple effects throughout your organisation that extend far beyond immediate delivery performance issues. The most visible impact is customer dissatisfaction, which manifests through negative reviews, increased customer service inquiries, and reduced customer loyalty. When customers experience late or incomplete deliveries repeatedly, they lose confidence in your brand's reliability, often leading to customer churn and reduced lifetime value.

The financial implications of poor OTIF performance are multifaceted and substantial. Direct costs include retailer penalties, expedited shipping charges to correct delayed deliveries, and inventory holding costs for products that couldn't be delivered as planned. Supply chain disruptions often compound these effects, as partners throughout your network lose confidence in your operational efficiency, resulting in less favourable contract terms and reduced priority during capacity constraints.

Poor OTIF performance also reveals underlying weaknesses in supply chain processes, indicating inadequate inventory levels, inefficient warehouse operations, poor demand forecasting, or insufficient supply chain visibility. The reputational damage from consistently poor performance can be particularly challenging to overcome, as customers readily share negative experiences through social media and review platforms, making customer acquisition more expensive and retention increasingly difficult.

Inventory Management: The Foundation of OTIF Success

Optimising Stock Levels for Consistent Performance

Effective inventory management & forecasting serve as the cornerstone of achieving consistently high OTIF scores. Without adequate stock levels strategically positioned throughout your distribution network, even the most efficient logistics processes cannot deliver complete orders on time. Strategic inventory positioning across multiple distribution centres reduces lead times and improves the likelihood of on-time deliveries by analysing customer demand patterns and geographic distribution to optimise placement and minimise shipping distances.

Safety stock calculations must balance the cost of carrying excess inventory against the risk of stockouts that damage OTIF performance. Advanced forecasting techniques that incorporate seasonal variations, promotional activities, and market trends help determine optimal safety stock levels for different product categories. Real-time inventory visibility across your entire supply chain enables proactive management of stock levels and helps prevent situations that could compromise OTIF performance.

Demand forecasting accuracy directly impacts your ability to maintain appropriate inventory levels for optimal OTIF performance. Statistical forecasting models that incorporate multiple variables - including historical sales data, market trends, and promotional plans - provide more accurate predictions than simple trend analysis. Machine learning algorithms can continuously refine these forecasts based on actual performance, improving accuracy over time and ensuring your inventory investment supports your OTIF goals while minimising carrying costs.
