Key takeawaysLine fill rate — fully fulfilled lines / total linesUnit fill rate — units shipped / units orderedOrder fill rate — 100%-fulfilled orders / total orders (the strictest) What fill rate is Fill rate measures how much of demand you fulfil from available stock at first delivery. It can be computed by lines, units or orders (order fill rate = fully fulfilled orders / total orders). Types of fill rate Line fill rate — fully fulfilled lines / total lines Unit fill rate — units shipped / units ordered Order fill rate — 100%-fulfilled orders / total orders (the strictest) Why it matters Low fill rate = lost sales and frustrated customers. At retailers, fill rate below threshold = OTIF penalties. It is the ‘In Full' component of OTIF, alongside ‘On Time'. How Azuvio helps Through correct allocation, realistic ATP and demand-based replenishment, Azuvio raises fill rate without overstocking: fewer stockouts on demanded products, with less capital locked in slow movers. Frequently askedDifference between fill rate and OTIF?Fill rate = the ‘In Full' component (how much of demand you fulfil). OTIF combines ‘On Time' and ‘In Full'. You can have good fill rate but poor OTIF if you deliver in full but late.What fill rate is good?It depends on industry, but 95%+ on lines is healthy in distribution. Order fill rate (fully fulfilled orders) is stricter and usually lower. Retailers impose contractual thresholds.How do I raise fill rate without overstock?Through per-SKU analysis: enough buffer on frequently demanded products, reduced stock on slow movers, realistic ATP and replenishment triggered by real demand, not intuition.
