The only vendor monitoring tool built for accounting firms — not enterprise AP teams
Connects to QuickBooks in one click. No vendor portals, no IT tickets, no DKIM configuration. Your vendors do nothing — you get alerts and a documented review process immediately.
How Vantirs monitors your clients
From first sync to every payment run — continuous monitoring and alerts without another spreadsheet.
Step 1
Connect QuickBooks
OAuth to your client's QuickBooks Online in one click. We sync vendors and invoice history.
Step 2
Fingerprint every vendor
We analyze payment patterns and build statistical profiles—so anomalies stand out instantly.
Step 3
Alert before pay runs
High-risk invoices surface in your queue with context — review, approve, reject, or call the vendor directly before payment goes out.
What we detect
Purpose-built signals for BEC and vendor impersonation—not generic "risk scores."
Bank account changes
Alerts you when a vendor's bank account details differ from prior payment history — so you can verify before approving.
Duplicate invoices
Detects invoices submitted twice — same vendor, same amount, different invoice number — before double-payment clears.
Amount anomalies
Statistical outliers vs. the vendor history—so unusual is measurable, not a hunch.
New vendor review
First-time vendors get explicit review—no payment history, no automatic trust.
Your auditor is about to ask about vendor bank verification
NACHA's 2026 rule changes require ACH originators to have documented, risk-based controls for vendor payment monitoring. Vantirs gives you a timestamped alert log and audit trail for every vendor — supporting your compliance documentation automatically.
- Bank account change alerts on every sync — logged with timestamp
- Full audit trail per vendor: who reviewed, when, and what was flagged
- Exportable monitoring report for E&O carriers and external auditors
- No manual process, no spreadsheet — documented review workflow by default
What auditors now ask
Do you have controls to monitor vendor bank accounts before ACH payments?
Yes — Vantirs alerts us when any vendor's bank account differs from prior payment history, so we can verify directly before payment.
Can you show me your vendor monitoring controls?
Yes — every invoice has a timestamped scan record with risk score, signals checked, reviewer, and decision. Exportable on request.
What happens when a new vendor requests payment?
Vantirs flags first-time vendors automatically for explicit review before any payment is approved.
How it works
Exactly what gets checked — and how
Vantirs reads your QuickBooks history. Every signal is derived from data that already exists in your books — no manual input, no vendor portals, no configuration.
Connect QuickBooks via official OAuth
Two-minute setup using QuickBooks' own OAuth flow. Vantirs receives read-only access — it cannot move money, create vendors, or modify any data in your books.
Vantirs builds a payment fingerprint per vendor
For every vendor across every client, Vantirs maps their historical payment destinations, typical invoice amounts, and billing cadence. This fingerprint is the baseline everything gets compared against.
Every new invoice is automatically scored
When a new invoice syncs from QBO, Vantirs scores it against that vendor's fingerprint. No manual submission — alerts are generated for your review on every payment run.
Anomalies surface with the specific reason
Alerts say exactly what changed: "Bank account routing number differs from the last 12 payments to this vendor" or "Invoice amount is 340% above this vendor's historical average." Your team reviews the evidence and decides — Vantirs never makes the payment decision for you.
Verifiable by your IT or compliance team
Read-only. No credentials stored. Revoke access from your QBO settings at any time.
All payment data encrypted at rest using AES-256-GCM. Bank account details are encrypted and hashed — never stored in plaintext.
Every invoice decision logged with timestamp, reviewer, and risk factors. Exportable for auditors.
Vendors do nothing. No signup, no portal, no disruption to existing payment workflows.
Every payment run deserves a second look

Important: Vantirs is a monitoring and alerting tool that surfaces anomalies for your review. It does not guarantee detection of all fraudulent activity, does not verify bank account ownership with external registries, and does not make or block payment decisions. All payment decisions remain the sole responsibility of the user. Always verify suspicious activity through direct phone contact with known vendor numbers before approving any payment.
