The usual failure mode
A permit PDF lands in email. Someone files it. The date sits in a filename or a cell. Six months later nobody owns the renewal.
What “good” looks like
Upload the document, confirm the extracted expiry, assign an owner, and schedule reminders early enough to act — for one site or every customer tenant.
