# MonitorPay alternatives: MonitorPay vs RealPayee and others

> MonitorPay is a usage-priced verification API: it validates IBANs and US accounts, matches payee names, checks ownership, VAT and EIN against registries, and monitors verified accounts for change. RealPayee verifies that the real vendor contact or executive asked for a bank change or payment, out-of-band, inside NetSuite, QuickBooks, Xero, Bill.com or Ramp. MonitorPay checks the account and the business; RealPayee checks the person. Teams can use both.

## What MonitorPay is

MonitorPay describes itself as "one API to validate accounts, confirm payees, verify ownership, and monitor for change". Its homepage lists IBAN validation, payee name matching, account ownership verification via government registries, VAT number checks, account status monitoring, continuous monitoring with alerts, and bulk validation by API or file upload, with coverage of 150+ countries and 100+ corporate registries.

It targets fintechs and payment providers, banks, marketplaces, and corporate treasury, AP and procurement teams. It also publishes EIN verification against IRS records and ACH account validation for US suppliers. Pricing is usage-based, from €0.10 per check with 100 free verifications and no monthly minimum, per its site. ERP connection is through its API, writing results back to the supplier record, rather than through packaged native connectors.

## MonitorPay vs RealPayee at a glance

|  | MonitorPay | RealPayee |
| --- | --- | --- |
| What it checks | Account validity, payee name match, ownership, VAT and EIN registry data, account status | Whether the real person (the vendor's known contact, or the real executive) actually made the change or request |
| Main trigger | API calls or bulk files at onboarding, before payment and via monitoring | Vendor bank-detail changes and payments above a threshold, detected in NetSuite, QuickBooks, Xero, Bill.com or Ramp |
| How it confirms | Automated data checks against bank formats and registries | Out-of-band by SMS, Slack or Microsoft Teams: phone-bound approval, or government ID plus live selfie |
| Typical stack | Any system via API (results written back to supplier records) | NetSuite, QuickBooks, Xero, Bill.com, Ramp |
| Coverage | 150+ countries (per MonitorPay) | Wherever the vendor contact or executive can receive SMS, Slack or Teams |
| Moves money | No; verification only | Never moves money. Holds the change or payment, then releases or blocks it |
| Evidence | Verification results per check | Audit record of who confirmed, how and when, for auditors and cyber insurers |
| Pricing | Usage-based from €0.10 per check (per MonitorPay) | Starter $250/month, Growth from $750/month, Enterprise custom |

## Where MonitorPay wins

- **Transparent, usage-based pricing** from €0.10 per check, with free verifications to start (per MonitorPay).
- **Account and entity data.** IBAN and US account validation, payee name matching, ownership, VAT and EIN checks in one API, which RealPayee does not do.
- **Developer-first.** Bulk validation and an API that fits fintechs, marketplaces and teams with engineering help.
- **International coverage** across 150+ countries (per MonitorPay).

## Where RealPayee wins

- **It verifies the person, not only the account.** A request from a hacked genuine vendor mailbox, or a fraudster's account that matches a plausible name, can pass data checks. RealPayee asks the vendor's known contact to confirm.
- **Executive and wire requests**, including deepfake voice or video, not only supplier bank data.
- **No build required.** RealPayee works inside NetSuite, QuickBooks, Xero, Bill.com and Ramp and holds the change or payment until confirmation.
- **Audit evidence** of who confirmed, how and when, for auditors and insurers.

## When to choose which

### Choose MonitorPay if

- You have developers and want to add account, payee and registry checks to your own product or payment flow.
- You validate many international accounts or need VAT and EIN checks at scale.
- You want pay-per-check pricing with no platform commitment.

### Choose RealPayee if

- Your risk is fake bank-change requests and executive impersonation that look genuine.
- You run NetSuite, QuickBooks, Xero, Bill.com or Ramp and want a hold-and-confirm control without building it.
- You need a named person's confirmation on record for every change and large payment.
- You want to see it on your own flow first: [book a demo](https://realpayee.com/demo).

## Can you use both?

Yes. MonitorPay can confirm that an account and business check out; RealPayee confirms that the real contact asked for the change. Running the data check inside the RealPayee hold covers both questions.

### Does MonitorPay integrate with NetSuite, QuickBooks or Xero?
