Vendor Verification: Process, Checklist & Software Guide

Vendor imposter fraud jumped from 34% to 45% of companies between 2023 and 2024, according to the Association for Financial Professionals’ 2025 Payments Fraud and Control Survey. Most businesses still verify a vendor once, at onboarding, and never look back.

That gap is exactly where fraud, compliance failures, and payment errors creep in. This guide covers what vendor verification means, why it matters, the step-by-step process, a practical checklist, and how to automate it inside your procurement workflow with Mekari Expense.

What is vendor verification?

Vendor verification is the process of confirming a supplier’s legal identity, business legitimacy, financial standing, and compliance status before onboarding them, and at regular intervals afterward.

It covers four areas: who the vendor legally is, whether their business is properly registered and licensed, whether their financial and banking details are accurate, and whether they meet your compliance and risk requirements.

Vendor verification is sometimes used interchangeably with vendor validation, but validation usually refers narrowly to confirming payment details before a transaction. Verification is the broader, lifecycle-wide process that validation sits inside.

Why vendor verification matters in procurement

1. Fraud is rising fast. 79% of organizations reported actual or attempted payment fraud in 2024, with business email compromise (BEC) cited as the most common attack vector by 63% of respondents (AFP 2025 Payments Fraud and Control Survey, via apexanalytix). Fraudsters increasingly impersonate real vendors to redirect payments.

2. Vendor imposter fraud is accelerating. The share of companies targeted by vendor imposter fraud rose from 34% in 2023 to 45% in 2024 (Commerce Bank, citing AFP 2025). Smaller businesses are especially exposed because they often lack dedicated fraud-detection teams.

3. Compliance and audit readiness depend on it. Unverified vendors create blind spots in tax documentation, licensing, and contractual obligations, which surface during audits or regulatory reviews.

4. Operational risk compounds. Paying an incorrect account, relying on a non-compliant supplier, or discovering a vendor doesn’t legally exist mid-contract all disrupt operations and erode trust with stakeholders.

The vendor verification process step by step

A structured vendor verification process generally follows six steps.

Step 1: Collect vendor documentation

Request business registration documents (such as NIB for Indonesian entities), tax identification (NPWP), bank account details, and relevant certifications or licenses.

Step 2: Verify legal identity and business registration

Cross-check the vendor’s registration against official government or business databases to confirm the entity legally exists and is active.

Step 3: Validate financial standing and bank details

Confirm bank account ownership matches the registered legal entity to prevent payments being redirected to fraudulent accounts.

Step 4: Screen for sanctions and risk flags

Check vendors against sanctions lists, watchlists, and any adverse public records relevant to your industry and jurisdiction.

Step 5: Assess compliance documents

Review category-specific requirements such as business licenses, insurance certificates, or industry certifications depending on what the vendor supplies.

Step 6: Approve, classify, and re-verify

Assign the vendor a status (unverified, pending, or verified), grant procurement access accordingly, and schedule periodic re-verification rather than treating the first check as final.

Vendor verification checklist

Use this checklist across four categories before approving a new vendor or re-verifying an existing one.

Legal and identity

• Business registration/license number confirmed against an official database
• Tax identification number (NPWP or equivalent) verified
• Legal business name matches across all documents
• Authorized signatory or contact person identified

Financial

• Bank account name matches the registered legal entity
• Bank account ownership confirmed before first payment
• Payment terms and currency documented
• Credit or financial standing reviewed for high-value vendors

Compliance and risk

• Sanctions and watchlist screening completed
• Required licenses or certifications collected and valid
• Insurance documentation on file (where applicable)
• Data privacy or security requirements met for vendors handling sensitive data

Operational

• Vendor category and risk level assigned
• Verification status recorded (unverified/pending/verified)
• Re-verification schedule set
• Vendor record linked to procurement and payment systems

Manual vs. automated vendor verification

Choosing vendor verification software

When evaluating vendor verification software, look for capabilities that fit into your broader procurement workflow rather than standing alone.

• Centralized vendor database. A leading business database for vendor verification should let you store, search, and update vendor records in one place, replacing scattered spreadsheets and email threads.
• Configurable verification status and approval flows. The software should support clear vendor statuses (such as unverified, pending, verified) and let you define who approves each stage based on your company structure.
• Document management. Vendors should be able to upload and update licenses, certifications, and bank details, with the system flagging expirations.
• Integration with procurement and payments. Verification status should directly gate purchase requests, POs, and payment processing, not sit in a separate system disconnected from spend.
• Audit trail and reporting. Every verification action should be logged and reportable for internal audits and compliance reviews.
