A contractor audit is often reduced to collecting licences and registers. That is only the beginning. The real question is whether the evidence describes the workforce actually deployed at the establishment and whether the principal employer can demonstrate meaningful oversight.
Start with the establishment footprint. Identify every site, contractor, work order, headcount category and period of deployment. A contractor appearing in a register but missing from the operational population is itself a control failure.
The next layer is reconciliation: attendance to wage records, wage records to bank evidence where available, statutory returns to headcount, licences to the actual activity and contract terms to what happened on the ground.
Findings should be graded. A missing signature is not equivalent to an expired licence, underpayment exposure or a contractor population that was never brought into the compliance process. Management needs to know what is administrative, what is financial and what can create regulatory exposure.
Principal-employer controls should also be tested. The contract may allocate responsibilities, but the audit should examine what the business actually monitored, escalated and retained.
Every material finding should have an owner, corrective action, evidence requirement and target closure date. Without that tracker, an audit report becomes a document rather than a control mechanism.
The best output is therefore an establishment-wise exposure statement supported by evidence and a closure tracker. It should allow management to answer: who was deployed, under which contractor, under what licence, paid on what basis, and what evidence supports the conclusion.
