Sentinel: Continuous AI Monitoring for Your Accounting Data

Sentinel detects anomalies, flags irregular transactions, and generates risk scores — automatically, in real time, with plain-English explanations.

How It Works

From connection to insight in four simple steps.

01

Connect your accounting system

Link Sentinel to Xero, QuickBooks, or your accounting platform in minutes. No complex setup required.

02

AI analyses your data

Our models learn your business's unique financial patterns using historical transaction data.

03

Anomalies are flagged with explanations

When something looks wrong, Sentinel surfaces it with a plain-English explanation and risk score.

04

Instant alerts & risk reports

Receive real-time alerts via email or dashboard so your team can investigate and act immediately.

Features

Everything you need to catch anomalies, fraud, and compliance gaps — before they cost you.

Continuous, automatic monitoring

Every transaction, invoice, bill, payment, contact, and payroll record is checked around the clock, catching issues before they turn into audit findings.

Broad coverage across finance & payroll

Works across journal entries, invoices, bills, payments, bank transactions, contacts, and payroll — so nothing falls through the cracks.

Multi-layer detection

Combines up to 80 proven rule-based checks with machine learning that learns your organisation's normal patterns, catching both known red flags and subtle statistical outliers.

Purpose-built fraud detection

Specifically designed to catch invoice redirection scams, payroll diversion, fake or shell vendors, duplicate payments, and other schemes finance teams worry about most.

Payroll & tax compliance built in

Flags ghost employees and payments to terminated staff wherever payroll data is connected, plus region-specific compliance checks where applicable data is available.

Explainable results, not a black box

Every flagged item comes with a plain-English reason, so teams can trust and act on alerts quickly.

Works out of the box

New customers get reliable detection from day one, with no setup or training period required.

Investigation workflow included

Assign, track, comment on, and resolve cases with built-in service-level targets, so nothing goes stale.

Instant alerts wherever your team works

Real-time notifications to Slack, Microsoft Teams, PagerDuty, or other tools your team already uses.

Professional-grade trust & security

Built to meet the data protection expectations of finance, audit, and compliance teams, with strict tenant data isolation and encryption of sensitive information.

Connects to your existing systems

Integrates directly with Xero and QuickBooks, including payroll, so there's no manual data entry or duplicate bookkeeping.

Key Benefits

Sentinel pays for itself by preventing errors and fraud before they cost you.

Reduce audit time

Significantly reduce manual review time. Sentinel surfaces what matters so auditors focus only on genuine issues.

Catch errors before they escalate

Identify duplicates, mispostings, and fraud indicators in real time — not in your next audit cycle.

Improve compliance & governance

Generate detailed audit trails and risk reports that satisfy regulatory requirements and board oversight.

Save on manual reviews

Reduce the cost of manual transaction reviews and redirect that resource toward strategic finance work.
