Backorder rate
Quick answer
The share of orders (or lines) that cannot be fulfilled immediately from stock and go on backorder: backordered / total × 100.
Key takeaways
- Insufficient safety stock on demanded SKUs
- Inaccurate demand forecasting
- Underestimated replenishment lead times
- No live visibility of real stock
What backorder rate is
Backorder rate measures how often you cannot fulfill an order immediately due to lack of stock, forcing it onto backorder (deferred delivery). It is the negative mirror of fill rate: a 95% fill rate means a 5% backorder rate.
Why it matters to the board
Every backordered order is a promise at risk: the customer waits, may cancel or switch to a competitor. A chronically high backorder rate signals poor stock planning and erodes trust and margin (partial shipments, double transport).
Common causes
- Insufficient safety stock on demanded SKUs
- Inaccurate demand forecasting
- Underestimated replenishment lead times
- No live visibility of real stock
How CRMconnect helps
CRMconnect provides live stock availability (ATP) and ties demand to replenishment, reducing backorders. When a backorder is unavoidable, it orchestrates allocation and automatic communication of the new promised date.
Real-world example
A distributor had a 12% backorder rate at seasonal peak. With demand-calibrated safety stock and live ATP, it dropped to 3% without raising total inventory.

Frequently asked
Is backorder rate the opposite of fill rate?+
Essentially yes. Fill rate measures what you fulfill immediately; backorder rate measures what stays outstanding. Together they cover 100% of demand.
Is a low backorder rate always good?+
Usually, but zero backorders can mean costly overstocking. The target is a balance between availability and tied-up capital.
