What the portal is actually checking
Most systems test three things: that required documents exist, that they are current, and that they match the contractor entity and the work category selected. The third is where errors cluster. A contractor registered under a general services category may be asked for a different document set than one registered for cleaning, and an incorrect category produces either missing-item flags or a compliant status that does not reflect the work being done.
The systems are also literal. A certificate that expires next week reads as compliant today and non-compliant on the day it lapses, with no grace period and often no warning to the client. That is why the portal's own reminder settings matter as much as the documents. Someone on the contractor side has to own the calendar, because the client usually discovers the lapse from a rejected site entry.
