When match tolerances quietly widen after go-live
Elevated three-way match tolerances often survive the project phase. Here is how we sample them during a financial audit of an AP automation application.
During the first weeks after an accounts payable automation application goes live, project teams often raise match tolerances so invoices keep moving. The temporary setting becomes the permanent one when nobody schedules a rollback date.
In fieldwork we ask for the tolerance history, not only the current screen. A sample of invoices near the old and new thresholds shows whether rush suppliers are driving permanent risk. Controllers who set a calendar reminder to restore tolerances before the second month-end avoid explaining the same exception to auditors two years running.
If your team cannot produce a tolerance change log, treat that as a finding in its own right during the financial audit of the accounts payable automation application.
