# Manual callbacks vs bank-account validation vs RealPayee

> There are three main ways to stop fake vendor bank changes and fake payment requests. **Manual callbacks** verify the person but depend on discipline. **Bank-account validation** (Eftsure, Trustpair, Ramp and Bill.com checks) verifies that the account belongs to the payee, but not who asked for the change. **RealPayee** verifies the real person out-of-band and records it. Most teams should combine account validation with person verification.

_Updated 2026-10-05_

Payment fraud against businesses usually isn't a bank hack. It's a convincing request - a vendor “changing banks”, a CEO who needs a wire today - that an employee acts on. Stopping it means answering two separate questions: **is this account really the payee's?** and **did the real person actually ask for this?**

The three approaches below answer those questions differently. None is perfect on its own; this page lays out what each one does and doesn't catch, so you can decide what fits your team.

## Side-by-side comparison

| Criterion | Manual callbacks | Bank-account validation | RealPayee |
| --- | --- | --- | --- |
| What it verifies | The person, by phone | The bank account and its owner | The real person, bound to their known phone or ID + live selfie |
| Catches vendor impersonation by email | Yes, if done to a known number every time | Partly - if the new account's owner doesn't match | Yes - the known contact must verify |
| Catches deepfake / phone / video executive requests | Partly - voices can be cloned; depends on challenge questions | Not designed for this | Designed for this - approval bound to the executive's device or ID |
| Catches fake bank-detail changes | Yes, when performed | Many - especially name mismatches | Yes - change held until verified |
| Effort per payment or change | High - manual calls, chasing, notes | Low - automated | Low for AP - the verified person taps to confirm |
| Audit trail | Manual notes, often inconsistent | Validation results logged | Who verified, how and when, per change or wire |
| Typical buyer | Any AP team | Mid-market and enterprise finance, treasury, procurement | Controllers, CFOs and AP managers at US companies ($20M–$500M revenue) |
| Price signal | Free, but costs staff time | Included in some AP suites; dedicated platforms usually quote-based | Based on payment volume - see [pricing](https://realpayee.com/#pricing) or [book a demo](https://realpayee.com/demo) |

## Manual callbacks

An AP team member calls the vendor's known contact (or the executive) on a number from your own records and confirms the request before anything changes.

**Examples:** Your AP team phoning a known contact; a written callback policy and checklist

**Pros**

- Free and available today; no integration needed.
- Verifies the person, so it catches impersonation by email.
- Widely recognized by auditors and often referenced in insurance verification conditions.

**Cons**

- Only as good as the discipline behind it: skipped under deadline pressure, or done with the number from the email.
- A voice on the phone can be cloned, and an inbound call is easy to fake.
- Evidence is often a note in a spreadsheet, if it exists at all.
- Takes AP time on every change and chases unreachable contacts.

**Best for:** Small teams with few bank changes and a strong control culture, or as the baseline for everyone.

## Bank-account validation

Software checks that a bank account exists and that its owner matches the vendor on record, often continuously across your vendor master file. In August 2026, Basware agreed to acquire Trustpair.

**Examples:** Eftsure and Trustpair (vendor-data and account-ownership validation); built-in checks in AP suites such as Ramp and Bill.com; bank services such as Early Warning Verify Account and Plaid Identity Match; micro-deposits

**Pros**

- Automated and scalable across thousands of vendors.
- Catches mismatched account names, typos and many mule accounts.
- Usually integrated into the ERP or AP workflow, with monitoring of the vendor master.

**Cons**

- Verifies the account, not the human: a request from a hijacked vendor mailbox to a plausibly named account can pass.
- Not designed for executive or deepfake requests to wire money.
- Coverage varies by bank and country.
- Dedicated platforms are typically priced for mid-market and enterprise budgets.

**Best for:** Teams with large vendor bases and high payment volumes that need continuous account-level checks.

## RealPayee

A vendor bank-detail change or high-value wire is held until the vendor's known contact or the real executive verifies out-of-band - a phone-bound approval or ID plus live selfie via SMS, Slack or Teams - then released or blocked with an audit record.

**Examples:** Triggers from NetSuite, QuickBooks, Xero, Bill.com or Ramp

**Pros**

- Verifies the person behind the request, including executive and deepfake scenarios.
- Enforces the hold, so verification can't be skipped under pressure.
- Produces an audit record of who verified what, when and how.
- Complements account-validation tools rather than replacing them.

**Cons**

- Newer than established AP suites: confirm your ERP and approval flow are covered on a demo.
- Does not by itself confirm bank-account ownership - pair it with account validation.
- Requires vendor contacts and executives to complete a verification step.

**Best for:** Controllers and CFOs at US companies who want person-level verification enforced, with evidence, on bank changes and large wires.

## When to use which

### Start with written callbacks - everyone

A documented out-of-band callback policy is the baseline. If you don't have one, start with our free [policy template](https://realpayee.com/templates/vendor-bank-change-policy).

### Add account validation when volume grows

If you onboard or change many vendors, automated account-ownership checks (built into Ramp or Bill.com, or dedicated platforms like Eftsure or Trustpair) catch mismatches at scale.

### Add person verification where impersonation is the risk

If you've seen fake vendor emails, executive impersonation or deepfake attempts - or your insurer asks for verification evidence - enforce out-of-band verification of the real person on bank changes and high-value wires.

### Best practice: layer them

Account validation answers “is this the payee's account?”. Person verification answers “did the real payee ask for this?”. Fraudsters only need you to skip one.

## Frequently asked questions

### What's the difference between account validation and person verification?

Account validation confirms that a bank account exists and that its owner matches the payee. Person verification confirms that the real vendor contact or executive actually made or approved the request. Impersonation attacks can pass the first and fail the second.

### Does RealPayee replace Eftsure, Trustpair or Ramp's vendor checks?

No. RealPayee verifies the person behind a change or wire; those tools verify accounts and vendor data. They are complementary, and many teams will want both.

### Are manual callbacks still worth doing?

Yes - a callback to a known number is one of the most effective controls when it's actually done. The weaknesses are consistency, cloned voices on inbound calls, and missing evidence.

### Which approach do auditors and insurers prefer?

Both look for evidence that verification happened, consistently, before payment. Whatever you use, keep a record of who verified, how, when and who approved. Check your insurance policy's specific verification conditions.

### Is RealPayee available now?

Yes. RealPayee is available for finance teams on NetSuite, QuickBooks and Xero. You can [book a demo](https://realpayee.com/demo) to see it on your payment flow.
