Continuous payment monitoring for finance teams: how to evaluate it

Continuous payment monitoring is the practice of verifying vendor and payment details on an ongoing basis, rather than only at onboarding or during periodic audits. It checks that bank account details, vendor identity, and payment instructions are still valid every time a payment is about to leave your account, not just the first time a vendor was added. For finance teams, the goal is to catch fraud, redirected payments, and data errors before money moves, while keeping the existing accounts payable workflow intact and satisfying compliance obligations.

This guide sets out the criteria finance leaders should use to evaluate continuous payment monitoring and vendor payment verification software: how to assess fraud detection, how to judge fit with your ERP and AP process, and how to weigh control over everyday payment errors alongside fraud.

Why continuous monitoring matters now

Payment fraud is no longer an occasional event. In the 2026 AFP Payments Fraud and Control Survey, most organizations reported they experienced attempted or actual payment fraud, and business email compromise (BEC) remained the most common vector. The financial scale is set out in the FBI's 2025 Internet Crime Report, which recorded $20.9 billion in reported losses, up from $16.6 billion the year before and BEC accounting for more than $3 billion.

The mechanism behind most of these losses is simple. An attacker compromises or imitates a vendor's email, sends a bank account change request that looks routine, and the payment is approved through the normal process. The control that should catch this, confirming the change is genuine, often happens through the same email channel the attacker is using.

AI has exacerbated this by removing the friction that used to expose a fake request: convincing emails, cloned vendor domains, and even voice calls are now cheap to produce at scale.

Periodic checks were built for a slower threat. Verifying a vendor once at onboarding tells you the details were valid on that day. It says nothing about the bank account change that arrives eight months later, which is exactly when most payment redirection fraud happens.

Some of this monitoring is also becoming a formal obligation rather than a best practice: Nacha's 2026 fraud monitoring rules introduce explicit monitoring expectations for organizations sending and receiving ACH payments.

Continuous monitoring versus periodic checks and manual verification

The three common approaches differ in when verification happens, what they catch, and how much manual effort they demand.

Manual verification and periodic checks share the same weakness: they leave gaps between the moments of review, and fraud is timed to fall into those gaps. Continuous monitoring closes the gap by treating every payment as a checkpoint.

The core criteria for evaluating continuous payment monitoring

Use these as the spine of any vendor evaluation. Each one maps to a question you can put directly to a provider. For larger organizations comparing platforms side by side, our guide to the best AP fraud prevention platforms for enterprise teams reviews the main options against criteria like these.

Fraud detection capability

Detection is only as good as the data it checks against. Ask what authoritative sources the software verifies bank account ownership against, and whether it confirms that the account belongs to the vendor you intend to pay, not just that the account exists and is correctly formatted. Strong detection cross-checks vendor identity, bank account ownership, and historical payment patterns, and it flags a mismatch before the payment is released rather than reporting it after settlement.

Watch for the difference between validation and verification. Validation confirms an account number is real and active. Verification confirms the account belongs to the intended recipient. Only the second one stops a redirected payment.

ERP and AP workflow fit

A control that sits outside your payment process will be worked around. Confirm the software integrates with your ERP or accounting system, whether that' NetSuite, SAP, Oracle, Microsoft Dynamics, Xero, or another, and that verification results appear inside the workflow your AP team already uses. The practical test is whether a payment officer sees a clear status before approving a payment, without leaving their normal screen or running a separate process.

Ask how vendor master data stays in sync, how the software handles a vendor record that changes in the ERP, and whether it supports your approval hierarchy rather than replacing it.

Control over payment errors, not just fraud

Most finance teams lose more to error than they expect: duplicate payments, transposed account numbers, payments to closed accounts, and stale vendor records. Good monitoring software treats these as first-class problems, not a side effect of fraud detection. Ask whether it flags duplicate or anomalous payments, identifies dormant or changed vendor records, and reduces the manual correction work that follows a misdirected payment. This is often where the clearest day-one return sits, because errors are far more frequent than fraud attempts.

Vendor and bank account verification depth

Depth is what separates a surface check from a real control. Ask how the software verifies a new vendor at onboarding, how it handles a bank detail change request, and whether it confirms changes through a channel independent of the one the request arrived on. The strongest providers verify out of band by design, so a change requested by email is never confirmed by replying to that email.

For organizations that pay internationally, confirm coverage across the countries and banking systems you actually pay into. Domestic-only verification leaves your cross-border payments unprotected. For wire payments specifically, data-quality changes such as the Fedwire ISO 20022 migration can cause rejected or returned payments, which is another reason to confirm details are correct before a payment is sent.

Coverage, alerting, and auditability

Coverage is the share of your payments the software can actually verify. A provider that verifies 95% of your payment volume automatically is materially different from one that verifies half and leaves the rest to manual review. Ask for the expected automated verification rate against a payment file like yours.

On alerting, ask what triggers an alert, how false positives are minimized, and who receives the flag. On auditability, confirm the software produces a clear, timestamped record of what was checked, what was flagged, and who approved each payment, because that record is what you will rely on during an audit or after an incident.

A practical evaluation checklist

Run a candidate provider against these before shortlisting:

• Verifies bank account ownership against authoritative sources, not just account format
• Confirms the account belongs to the intended vendor, not only that it exists
• Integrates with your ERP or accounting system and shows status inside the AP workflow
• Verifies bank detail changes through an independent, out-of-band channel
• Flags duplicate, anomalous, and error-prone payments, not only suspected fraud
• Covers the countries and banking systems you pay into, including cross-border
• Publishes an expected automated verification rate for a payment file like yours
• Produces a timestamped audit trail of checks, flags, and approvals
• Supports your existing approval hierarchy rather than replacing it
• Backs verified payments with a clear commitment, and states the terms plainly

Questions to ask a provider during evaluation

• What sources do you check bank account ownership against, and how current are they?
• Do you verify that the account belongs to the vendor, or only that the account is valid?
• How does a bank detail change get confirmed, and through which channel?
• What share of our payment volume would you expect to verify automatically?
• How does verification appear inside our ERP and approval process?
• How do you reduce false positives, and what happens when one occurs?
• What audit record do we get for each verified payment?
• What does your guarantee or commitment cover, and what are the conditions?

What good looks like across the payment lifecycle

Continuous payment monitoring is one part of a broader set of continuous controls for outgoing payments. The strongest approach is not a single check bolted onto the end of the process. It runs across the full payment lifecycle: verifying a vendor at onboarding, re-verifying when bank details change, and confirming account ownership at the moment each payment is approved.

This is the model Eftsure uses, combining independent ownership verification, automated registry and compliance checks, and a verification layer that sits inside the AP workflow, with verified payments backed by a guarantee, subject to Eftsure's standard terms and conditions. Used as a benchmark, it shows what end-to-end verification should cover, regardless of which provider you choose.

The test of any provider is whether it closes the gap that fraud relies on: the moment between a change request and a payment, where a single unverified detail can send money to the wrong account.

Frequently asked questions

What is continuous payment monitoring?

It is the ongoing verification of vendor details, bank account ownership, and payment instructions every time a payment is made, rather than only at onboarding or during periodic audits. It is designed to catch redirected payments, identity mismatches, and errors before money leaves your account.

How is continuous payment monitoring different from a periodic audit?

A periodic audit reviews payments and vendors at set intervals, so it can only catch issues present at the point of review. Continuous monitoring checks every payment as it happens, which closes the gap between reviews where most payment redirection fraud occurs.

Does continuous payment monitoring integrate with our ERP?

The better providers integrate directly with major ERP and accounting systems and surface verification results inside the AP workflow, so payment officers see a clear status before approving a payment. Confirm support for your specific system during evaluation.

Will it stop business email compromise?

It reduces the risk by verifying bank account ownership independently of email, so a change requested through a compromised or spoofed email is not confirmed through that same channel. No control eliminates fraud entirely, but out-of-band verification removes the mechanism most BEC attacks rely on.

Does it help with payment errors as well as fraud?

Yes. Strong monitoring software flags duplicate payments, transposed account numbers, and stale vendor records, which are more frequent than fraud attempts and often deliver the clearest early return.

How do we measure whether it works?

Track the share of payments verified automatically, the number of redirected payments and errors caught before settlement, and the reduction in manual verification time for your AP team.
