A spreadsheet someone owns personally
The expiry dates live in a workbook on one person's drive, maintained out of goodwill. When they move on, the organisation inherits a file nobody trusts and nobody wants to own.
Licences, tickets, verifications of competency and inductions tracked against the worker and the site that requires them, with the evidence attached where it was captured. An audit becomes a query rather than a fortnight of hunting.
The expiry dates live in a workbook on one person's drive, maintained out of goodwill. When they move on, the organisation inherits a file nobody trusts and nobody wants to own.
A verification of competency or a high risk work licence expires with no alert attached to it. The first anyone hears is a refusal at the gate, or an incident review that finds it afterwards.
Asked to evidence a crew's competency for a client audit, someone spends days pulling certificates out of inboxes, folders and personal drives, then hopes the set is complete.
Without one matrix the same refresher gets booked by two coordinators, while the worker who actually needed it this month is missed entirely.

What a role on a site demands is written down once, so compliance is measured against a standard rather than against an opinion.

The certificate, verification or induction record is attached to the worker when it happens, not filed later into a folder somebody has to find.

Every dated item carries its expiry, and the ones approaching appear on a list far enough ahead to rebook without losing a shift.

Role by role and site by site, who holds what and what is short. It updates as records change instead of being rebuilt monthly.

Refreshers are raised from the same list that found the gap, so the same course is not booked twice and the person who needed it is not missed.

A client asks for evidence and the answer is filtered from live records with the documents attached, in minutes rather than days.
