How this calculator works
Measure how much of a retailer's ordered unit quantity a supplier delivered by the assessed receipt cut-off. Unit fill rate shows quantity completeness but does not establish whether the delivery was timely or damage-free. 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 purchase order fill rate result?
Match accepted receipts to the same purchase orders and cut-off, excluding rejected or cancelled quantities consistently. Use one consistent reporting period and document any exclusions or channel filters.
What can distort this purchase order fill rate estimate?
Line fill, order fill, substitutions, quality failures, split deliveries and late receipts need separate analysis. Compare like-for-like periods before treating a change as operational improvement.
Does this purchase order fill rate calculator confirm compliance?
No. It is a transparent operational estimate only. Match accepted receipts to the same purchase orders and cut-off, excluding rejected or cancelled quantities consistently. Obtain qualified advice where consumer, privacy, spam, tax or accounting obligations apply.
