Your results
Calculation breakdown
- Picking accuracy
- correctly picked assessed lines ÷ all assessed order lines × 100
Worked example
If 49,600 of 50,000 assessed order lines have the correct item, variant and quantity, picking accuracy is 99.2% with 400 errors.
Assumptions
- Each assessed line has equal weighting.
- Correction records use the same definition of a picking error.

How this calculator works
Measure the share of assessed e-commerce order lines picked with the correct product, variant and quantity before dispatch. Line accuracy focuses on warehouse picking and does not claim an entire multi-line order was perfect. Inputs and intermediate quantities remain visible so Australian operators can reconcile the result with point-of-sale, inventory, fulfilment, website or campaign records.
Frequently asked questions
Which records should I use for the order picking accuracy result?
Define a correct line in advance and use scan, audit or correction records from the same warehouse and period. Use one consistent reporting period and document any exclusions or channel filters.
What can distort this order picking accuracy estimate?
Undetected errors, packing mistakes, damage, substitutions, weighting and sampling design can change the measured rate. Compare like-for-like periods before treating a change as operational improvement.
Does this order picking accuracy calculator confirm compliance?
No. It is a transparent operational estimate only. Define a correct line in advance and use scan, audit or correction records from the same warehouse and period. Obtain qualified advice where consumer, privacy, spam, tax or accounting obligations apply.
