The questions we hear most.
Does KoalaDoc work on a phone with patchy coverage?
Yes. The signing page is lightweight and loads on 3G; once a signer has it open they can complete the document offline and submit when signal returns.
Can the head contractor see who's signed the SWMS for today?
Yes. Project owners and admins see real-time signing status for every worker on every active envelope.
Is the payment-claim delivery record strong enough for a SoP-Act adjudication?
Our timestamped, hash-chained delivery and view record is designed to satisfy the evidentiary standard adjudicators look for. We can't guarantee a specific adjudication outcome, but the record itself is solid.
Compliance isn't a tick-box. It's the foundation.
