Purchase Orders & Purchasing Controls Practical guide
When an Invoice Shows More Units Than the Order
Compare ordered, shipped, received, and billed quantities
The short answer
An invoice can exceed an order because of a partial shipment followed by a second bill, a documented change, a unit-of-measure conversion, or an actual billing error. The receiving record is the bridge between what was ordered and what arrived.
How to approach it
Reconcile each stage before raising a dispute: approved quantity, amendments, packing slip, received amount, and previously billed amount. Keep any short-shipment or backorder note attached to the same order.
- Confirm the order quantity and approved changes
- Count received units using the same unit of measure
- Check prior invoices for already billed quantities
Could this affect your business?
- Can the reviewer locate the approved order and every written change?
- Do you know what arrived or which service milestone was accepted?
- Is the person approving payment able to see the source evidence?
