01
The first invoice after a rate change.
An amendment changes the monthly base to $10,300 from August 1, and the August invoice still shows $10,000. The comparison puts the clause, effective date and $300 difference on one line; your billing team checks for a credit before correcting.

Extra visits billed in a month.
The service log and the invoice both show three additional visits. The comparison shows the quantity and the rate from the schedule beside the billed amount and marks the line as a match, so the question is closed without tracing it by hand.

An amendment that refers to something missing.
A service schedule points to pricing in Amendment 2, which isn't among the documents. The comparison names the missing record and leaves the amount open rather than guessing. You add the amendment and use the included rerun.
