Checks the payroll run before the money leaves
Payroll is the largest recurring payment most organisations make, it runs on a deadline that cannot slip, and it is almost never reviewed before it is paid. The review happens afterwards, when an employee notices — and only for errors in their favour, because nobody reports being overpaid.
That asymmetry is the problem. Underpayments get corrected because somebody complains. Overpayments accumulate silently: the leaver still on the run, the allowance that outlived the role it was attached to, the salary change applied twice, the contractor paid through payroll and through accounts payable in the same month.
Payroll software calculates correctly — that is not the failure. It calculates correctly from inputs nobody checked, and those inputs come from a different system owned by different people.
This agent reads the run before it is paid. It compares every line against the contract, against the previous period, and against who actually joined and left, and reports what changed without an explanation. Timing is the entire value: a finding the day before is a correction, and the day after it is a conversation about reclaiming money someone has already spent.
It pays nothing, changes nothing, and never sees a bank detail it could act on.
Before the payment, not after the complaint.
The kind that damage trust far beyond the amount.
Including the month the payroll manager is on leave.
The day before is a correction. The day after is asking an employee to return money they have already spent.
Every change in pay, and whether anything on record explains it. Unexplained is the finding.
Nobody reports being overpaid, so this one never surfaces on its own.
A change applied twice, or someone paid through payroll and accounts payable in the same month.
Not against what was paid last time — that only proves the error is consistent.
It has no access to a payment file or a bank detail, and it never will.
Why HR & People in particular. Errors are only reported in one direction — nobody reports being overpaid. The leaver still on the run, the allowance that outlived the role, the change applied twice: all silent, all recurring.
Runs unattended
Started by you or by an event, and it finishes on its own. Nothing waits for someone to be at a desk.
The same standard every time
The two-hundredth item is held to the bar the first one was. Consistency is the part people cannot sustain.
It cannot act on its own
Payroll Assurance Agent has no path to sending, spending or committing. That limit is why its output is safe to act on.
This agent runs server-side through the PROMIVO runtime. Each run is logged step by step and every tool call is permission-checked before it executes.
Read-only by design. This agent has no path to sending, spending, publishing or committing anything. Where that limit is the product, removing it would remove the reason to trust the output.

No. It reads a draft run and reports on it. It has no route to a payment file, a bank detail or the payroll system, and adding one would make it a different and far more dangerous product.
It must, to do the job. It reports by employee reference rather than by name where references are supplied, and it never discloses one person's pay in a finding about another.
No. It is the second pair of eyes they never get, on a deadline where there is no time for one. Every finding goes to them to judge.
