How Zip prevents risky payments before money moves

A careful AP reviewer would check a few things before approving a new payment method. Does the bank info on the form match the voided check? Is the email asking for the change actually from the vendor's domain? Has this routing number shown up before? Is the bank account even real?

At a handful of vendors a week, a single person can do that. At enterprise scale, with thousands of payment methods moving through approval queues, almost no one can.

Bank Account Verification and Payment Risk Insights are how Zip solves this problem. These are AI skills that run automated fraud and identity checks on every payment method, invoice, and vendor document as it moves through approval, then surface specific alerts to the right approver at the right step. Across Zip customers, the system has flagged over $200 million in risky payments. Anomalies it surfaces have shown to be 15x more likely to be fraudulent than baseline.

What Bank Account Verification confirms

Bank Account Verification runs the moment a vendor submits a new payment method. Zip queries verification providers to confirm the account exists, is open, and belongs to the named account holder. Coverage spans institutions in 30+ countries through a few different paths:

• US accounts are verified against industry bank data networks, with real-time micro deposit fallback via RTP.
• International accounts route through JP Morgan's Global Account Verification service.
• EU and UK markets use standardized Confirmation of Payee schemes built directly into banking rails.

Results surface to the payment method approver as one of three outcomes: account verified, name matched, or a specific discrepancy to investigate.

What Payment Risk Insights checks

Payment Risk Insights analyzes data already in Zip (vendor records, invoice history, supporting documents, user activity) and flags discrepancies that fit known fraud patterns.

On payment method submission, it checks whether bank details match the supporting documents, whether the account holder name matches the vendor record, and whether the routing number appears on fraud lists or is unusual for business payments. 

Zip flags when the vendor user submitting a new payment method recently reset their password or MFA. Credential resets immediately before a payment method change are a hallmark of account takeover, and this alert routinely surfaces fraud attempts that would otherwise look routine. Zip also flags when the submitting user's email domain differs from other contacts at the same vendor.

The moment an invoice hits the inbox, Payment Risk Insights checks whether the sender's domain matches the vendor's known contacts, whether payment instructions on the invoice align with the selected payment method, and whether that method fits the vendor's invoice history. 

AI-powered signals layer urgency language, extreme discount terms, PDF metadata anomalies, and company information inconsistencies that pattern-match to known fraud tactics.

One of the most common patterns in production is a vendor email arriving just before the invoice; manufactured urgency designed to override a reviewer's judgment. Payment Risk Insights prevents that timing signal automatically.

Where the checks happen

Both features sit inside Zip's existing Procure-to-Pay workflow at three touchpoints, without any configuration or separate tools needed.

1. Payment method approval. When a vendor submits new bank details, results surface to the approver before sign-off. This is the first and most important intervention point; catching a fraudulent payment method before it gets attached to any invoice.
2. Invoice review. When a bill is coded and a payment method is selected, Zip surfaces anomalies in the invoice, sender, or payment method to the bill approver. This prevents the second-most-common vector: a legitimate-looking invoice routed to an illegitimate account.‍
3. Payout group approval. Before a batch executes, unresolved alerts from earlier steps surface to the payout approver as a final check.

Availability

Payment Risk Insights is generally available now for Global Payments customers, with alerts activating automatically. Bank Account Verification is available as an opt-in add-on for Global Payments and Procure-to-Pay customers. 

Both features were refined in beta before general availability and are part of Zip's broader AI Automation for Procure-to-Pay suite.
