Why the signed list is not enough
A signed inspection list proves that someone was there on one day. It does not prove what happened in the weeks in between, and that is exactly what an auditor asks about as soon as they see an infestation in the history. The question then is not “were you there?”, but “how long has this been going on?”.
A digital log has an answer to that for every single day, because every station reported every day: activity or no activity. Twelve data points a year become a continuous history, and an assumption becomes a date.
How the auditor gets access
Two ways, both without preparation: select the period and site and export as a PDF, or give the auditor read-only access so they can go through the history themselves. Many businesses now prefer to show it live rather than on paper, because follow-up questions can be cleared up right at the screen.
You set the retention period to match what your standard requires. Export is possible at any time, even retroactively for past years.
