Fictional sample review Records disagree

The invoice lists two more units than the purchase order.

In this fictional example, Meridian Medical Systems Ltd. lists 14 Mobile Diagnostic Workstations on the invoice. The purchase order lists 12 at the same unit price. The difference is 2 units, or $7,300.

Calculation

(14 invoiced − 12 approved) × $3,650 = $7,300

Both fictional records use USD and state the same unit price.

What the reviewer should check

Three explanations could resolve this difference. Each is a possibility, not a conclusion.

  1. A later approved change increased the quantity.
  2. The invoice combines items from another purchase order.
  3. One of the source records contains an incorrect quantity.

ProcureTrace identifies the disagreement. The reviewer determines whether another authorization or source record resolves it.

What it does not establish

  • That the supplier acted improperly.
