What is OTIF in fashion?
OTIF (On Time In Full) measures the share of orders or lines delivered by the agreed date and in the full ordered quantity.
In short
OTIF, short for On Time In Full, is a supply chain metric showing the percentage of orders delivered both within the agreed time window and with the complete quantity. It is widely used by retailers to measure wholesale suppliers and by brands to measure factories.
How does it work in practice?
An order or order line counts as OTIF only if it meets both conditions. Definitions must be agreed in detail:
- On time: against the requested date, confirmed date or a window, and measured at shipment or receipt.
- In full: at order, line or unit level, and whether tolerances apply.
- Whether partial shipments, substitutions or early deliveries count.
Data comes from purchase orders, order confirmations, ASNs and goods receipts. Many retailers share OTIF results on supplier scorecards each season.
Why does it matter for fashion businesses?
Late or incomplete deliveries shorten the full-price selling period, leading to markdowns and lost sales. Retailers may apply chargebacks for non-compliance, and poor OTIF can affect a brand's order volume in future seasons. Internally, OTIF highlights where problems begin, whether in late fabric, capacity shortages or warehouse processing.
How is AI changing it?
Predictive models analyse production milestones, supplier history and shipping data to flag orders at risk of missing OTIF early enough to act. Supply chain control towers combine these signals so planners can expedite, reallocate or inform customers in advance. AI can also reconcile mismatched order and receipt data that distort OTIF calculations.
Common pitfalls
- Different definitions between brand and retailer, causing disputes.
- Measuring only at order level, which hides chronic line shortages.
- Optimising OTIF by shipping early, which retailers may not accept.
A practical first step is to agree a written OTIF definition with each key retail partner and to calculate the metric from the same data on both sides, so that weekly reviews focus on root causes rather than arguing about the numbers.
Frequently asked questions
What is the difference between OTIF and fill rate?
Fill rate measures only quantity delivered versus ordered. OTIF requires both the right quantity and the right timing.
Why do retailers charge penalties for low OTIF?
Late or short deliveries cost retailers sales and operational effort. Penalties encourage suppliers to meet agreed terms, and the rules are usually set out in vendor compliance manuals.
