The only vendor verification 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 protected immediately.
How Vantirs protects your clients
From first sync to every payment run—continuous controls 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—approve, reject, or escalate with confidence.
What we detect
Purpose-built signals for BEC and vendor impersonation—not generic "risk scores."
Bank account changes
Flags when an invoice asks for a different bank account than prior payments to that vendor.
Email domain spoofing
Surfaces sender domains that don't match known vendor domains—including look-alikes.
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 verify that bank account details belong to the intended recipient before every payment. Vantirs gives you a documented, auditable verification record for every vendor — automatically.
- Bank account change detection on every invoice — logged with timestamp
- Full audit trail per vendor: who approved, when, and what was flagged
- Exportable compliance report for E&O carriers and external auditors
- No manual process, no spreadsheet — defensible documentation by default
What auditors now ask
Do you verify vendor bank accounts before ACH payments?
Yes — Vantirs flags any bank account change vs. prior payment history before your client pays.
Can you show me your vendor verification controls?
Yes — every invoice has a scan record with risk score, factors checked, and approver.
What happens when a new vendor requests payment?
Vantirs flags first-time vendors automatically and holds them for explicit review.
From accounting firms using Vantirs
Trusted by the teams writing the checks
“We nearly wired $84,000 to a spoofed vendor. Vantirs caught the bank account change 20 minutes before the payment run. That one catch paid for years of subscription.”
“During Q4 close we process 300+ vendor payments a week. I used to manually spot-check maybe 10% of them. Now every single invoice gets scored automatically — I sleep better.”
“Our E&O insurance carrier asked us to document our AP review controls. Vantirs gave us a full audit trail for every invoice decision. That conversation went from painful to easy.”
“Three of our clients got BEC phishing attempts in the same quarter. Vantirs flagged all three bank account changes before any payment went out. That's the whole product right there.”
“I manage AP for 14 clients. Keeping track of which vendors are legitimate across all of them was a spreadsheet nightmare. Vantirs just handles it — vendor history, anomaly flags, the works.”
“A client's construction vendor changed their routing number mid-project. Old me would have approved it after a quick email. Vantirs flagged it as high risk and made me call the vendor directly — good thing I did.”
Every payment run deserves a second look
