Evidence integrity
What is an append-only evidence trail — and why frontline operators need one
When a client disputes whether a job was done — or a worker disputes their pay — the question is always: what does the record say, and could anyone have changed it?
Append-only, in plain English
When a client disputes whether a job was done, or a worker disputes what they were paid, the question is always the same: what does the record say — and could anyone have changed it?
An append-only record is one you can add to but not quietly edit or delete after the fact. New events get written; history stays intact. That’s the difference between a spreadsheet, where anyone can change a cell, and a trail you can actually stand behind.
Why it matters for frontline work
Shifts, approvals and incidents are exactly the events that get argued about weeks later. If your only record is an editable file or a chat thread, you can’t show what it looked like at the time. An append-only trail means the record from the shift in question still exists, unchanged.
How Emprovia OnSite uses it
Shift clock-ins, approvals and incident logs are written to an append-only evidence trail, so you have a durable record to produce in a client or pay dispute. Where a worker’s account and a confirmer’s account differ, both are kept side by side — never overwritten — so a genuine difference can be reviewed instead of quietly erased. Those same approved hours are what export to Xero at pay time.
The honest limit
This is a record-integrity feature — not a compliance certification or an audit sign-off, and we don’t claim it is. It’s about being able to show what happened, not a regulatory stamp.
