Deploying agents for your back office?

Your team writes the rules in plain English. Novarch checks every agent action before it runs: it blocks what breaks them, and hands close calls to a person with the evidence attached.

WHAT SLIPS THROUGH A BUSY BACK OFFICE

What's the biggest issue in your back office?

Pick the ones that cost you.

01 We do the work. We do not always bill all of it, or at the right rate.

What went out on the invoice is checked against what was delivered and the terms you sell on: the extra day, the rush rate, the line that never made it on. What slipped comes back as a list, in dollars.

The free billing audit

02 We paid an invoice twice, or paid the wrong amount, and found out at month end.

Every payment is checked against the order, the contract and the vendor on file: a duplicate, an amount over what was agreed, a bank account that changed last week. When software is doing the paying, a close call waits for a person, and if the check cannot be reached, nothing goes out at all.

The close call

03 How we do things lives in three people’s heads, and one of them is out this week.

The person who owns the work writes the rules in the words the office already uses: who can approve what, which rate applies, when a credit needs a second signature. No IT project, and the rule holds when they are out.

Who writes them

04 A customer disputes an invoice, or the auditor asks why, and it takes a week to answer.

Every check is written down as it is made: the rule it cited, the lines it read, who signed off, and the record does not change after the fact. Answering is a lookup, and it takes minutes.

The record

WHAT IT TAKES TO SET UP

One integration, then it belongs to your team.

An engineer is involved once. After that, the people who own the work run it, which is the point: they are the ones who know what should have been stopped.

ONCE

An engineer

Registers the gate where your agent already calls its tools, and says which of those tools read and which ones commit. Your systems of record do not change.

About an afternoon of work.

WHENEVER THE POLICY CHANGES

The person who owns the work

Your AP manager, your project manager, your claims supervisor. Writes the rules, in the words the team already uses, and tries them against real traffic before committing them.

No ticket to file and no release to wait for.

AS THEY COME UP

Your team

Close calls land in one place, each with what the agent was about to do, the rule it tripped and the evidence already attached. Approve or deny, with a reason.

One queue, and nothing runs while it waits.

Writing rules, approving close calls and disputing a block are separate permissions. Every one of them is recorded with a name, a time and a reason, and the original decision stays in the record.

THE DECISION LEDGER

Your workflows keep running. You only look at what needs you.

Every action that crossed the gate, newest first, with the verdict on each. Cleared means it was checked against your rules and passed, counted over thirty days. Paused and blocked are what is on someone’s desk right now, and nothing executes while it waits.

Payments, purchase orders and refunds. Three agents, one queue.

THE SCREEN BEHIND ONE PAUSE

The close call lands on someone’s desk.

A block is the system’s decision. A pause is yours.

The agent is holding. Nothing has executed.

Approve and it picks up where it left off. Deny and the session ends. If nobody answers in time it fails closed, and the payment does not go out.

Why it paused

The vendor’s bank account changed 5 days ago and nothing on file confirms it: no callback note, no Finance ticket. Every other check passed, which is why the agent submitted it. Whether that call happened is the kind of thing a person simply knows.

Every decision is recorded with a name, a time and the reason given. Mis-clicks get a two-second undo on the button itself.

THE RECORD BEHIND ONE BLOCK

Audit-ready the moment it happens.

Every decision writes itself down as it is made, so there is nothing to reconstruct later. Your team gets enough to argue with it today, and an auditor gets enough to re-perform it a year from now. Same document.

The rule it cited, the signals it read, the model that judged it.

A block is final, so this record is what your team disputes against, and the dispute lands in the record beside it.

The record lives in your deployment: your own cloud and your own database, or a single-tenant instance we run for you on shared infrastructure. One customer per database, never pooled.

BLOCKED · OFF-CYCLE WITHOUT EXCEPTION TICKET

Rule cited

Any off-cycle payment without a recorded exception ticket must be blocked. Off-Cycle Without Exception Ticket
Written in plain English by Dave Thompson, Accounts Payable Manager

Why it was blocked

This payment breaks the off-cycle policy: the payment is off the vendor’s normal cycle; no Finance exception ticket is referenced. Vendor identity, amount, and domain match all passed in isolation — the violation is the missing audit trail, not the payment. The agent has no way to know that process exists; this rule is what enforces it.

Signals cited

Signal	Value
Billing cycle	off the vendor’s normal billing cycle
Exception ticket	no exception ticket is referenced
Vendor in master DB	the vendor is on file
Submission hours	submitted in business hours
Urgency pressure	no urgency language
Amount vs approval ceiling	$9,750.00 of $25,000.00 (39%)

Signal values are recorded at the moment of the decision, not summarised after it. The decision ledger is append-only.

HOW IT STARTS

You watch it work before you turn it on.

Nothing is enforced on day one. We start against your own recorded history, where being wrong costs nothing.

01
We write your first rules with you, in the words your team already uses.
02
We replay them against your own history, before anything is enforced.
03
For an agent, you turn enforcement on when the record convinces you.

PILOT PROGRAM

We're working with back-office teams now.

Start with a free billing audit, or with an agent that's live or waiting on approval.

Our founding team works directly with a designated operator on your side. You get the product at a discount earlier than it ships publicly, and we get the kind of feedback we can't manufacture from a desk.

Right fit:

Work that touches money or commitments, done by your people or by an agent.
A real audit obligation, regulator, customer, or internal.
A willing operator who'll triage with us once a week.

THE LOOP

It gets sharper the longer it runs.

Enforcement produces a record. The record is what makes the next rule change safe to make.

RUNNING TODAY

Test a rule against your own traffic.

Change the wording, replay it over everything the gate has already seen, and read what would have changed before you commit it.

A replay changes nothing. The new wording is not in force until someone commits it, and the version that was in force at each decision stays on the record.

The record proposes the rule.

The same history your operators have been deciding against, read back as the rule nobody has written down yet, with the evidence it would have to carry.
