The Real Cost of Skipping Verification

A single bad supplier can damage cash flow and reputation. The most common losses come from a few predictable failures.

• Payment fraud: A "factory" takes a deposit, then disappears.
• Trading companies posing as factories: You pay markups and lose quality control.
• Quality failures: Goods arrive defective, late, or non-compliant.
• Compliance gaps: Labor or environmental violations expose your brand.

VALO Vietnam's view: Most sourcing disasters are not bad luck. They are skipped verification steps that a simple checklist would have caught.

Why Vietnam Needs a Local Lens

Vietnamese business documents and registration systems differ from Western norms. Communication can be indirect, and English fluency varies by region.

Verification that works in the US may miss local signals. Local knowledge turns a generic check into a reliable one.

The 15-Point Supplier Due Diligence Vietnam Checklist

This checklist is your master framework. Work through every point before signing a contract or sending a deposit.

Legal and Identity Checks

These four points confirm the company legally exists in Vietnam.

1. Enterprise Registration Certificate (ERC): Confirm the legal name, address, and registration number.

2. Tax code verification: Match the tax code to the registered entity.

3. Business scope: Confirm the license actually covers your product category.

4. Years in operation: Check the registration date against claimed experience.

Capacity and Operations Checks

These points confirm the supplier can actually make your product.

5. Factory ownership: Verify they own or lease the production site, not subcontract it.

6. Production capacity: Match monthly output to your order volume.

7. Equipment and machinery: Confirm the right machines exist for your product.

8. Workforce size: A realistic headcount should match claimed capacity.

Compliance and Quality Checks

These points protect your brand and your shipment.

9. Certifications: Verify ISO, BSCI, or product-specific certificates with issuing bodies.

10. Quality control system: Confirm documented inspection and defect-handling processes.

11. Export experience: Check past shipments to your region.

12. Labor and environmental compliance: Confirm safe, lawful working conditions.

Financial and Reputation Checks

These final points reduce payment and reliability risk.

13. Financial stability: Review basic financial health and payment terms.

14. Bank account match: The account name must match the registered entity exactly.

15. Client references: Contact at least two existing buyers directly.

Document Verification: How to Confirm a Vietnamese Supplier Is Real

Document verification is the foundation of supplier due diligence Vietnam. Paper can be faked, so you must verify against official sources.

Start With the Enterprise Registration Certificate

The ERC is Vietnam's core company document. It lists the legal name, head office, charter capital, and legal representative.

Request a copy early. Then confirm the details against the national business registration portal.

Cross-Check the Tax Code and Business Scope

Every legitimate company has a unique tax code. The code should link to the same legal name and address as the ERC.

Also confirm the registered business scope. A company licensed only for trading is likely not a real factory.

Verify Certificates at the Source

Never accept a certificate image at face value. Many are expired, edited, or borrowed.

• Confirm the certificate number with the issuing body.
• Check expiry dates and the named legal entity.
• Match the scope of the certificate to your product.

VALO Vietnam's view: A verified document is one you confirmed independently, not one the supplier emailed you.

Factory Audit: Verifying Capacity on the Ground

A factory audit confirms what documents cannot. It proves the supplier produces goods rather than reselling them.

What a Factory Audit Covers

A strong audit inspects the physical site and live operations. The goal is evidence, not a sales tour.

• Facilities and equipment: Machines match the claimed product line.
• Production lines: Work in progress reflects real, active output.
• Quality control stations: Inspection happens at defined checkpoints.
• Working conditions: Safety and labor standards are met.

On-Site Visit Versus Virtual Audit

An in-person audit is the gold standard for high-value orders. A trained inspector spots staged setups and borrowed equipment.

When travel is impossible, a live video audit is the next best option. Avoid pre-recorded videos, which are easy to fake.

Audit Reporting

A useful audit ends with a clear, documented report. It should include photos, capacity findings, and a pass or fail recommendation.

This report becomes your decision record. It also strengthens your position in later negotiations.

Red Flags: Warning Signs to Stop and Reassess

Some signals appear long before a contract. Spotting them early saves money and stress.

Documentation Red Flags

These signs suggest the company may not be what it claims.

• No ERC or refusal to share registration details.
• Tax code that does not match the company name.
• Certificates with no verifiable issuing body.

Behavioral Red Flags

How a supplier acts often reveals more than its paperwork.

• Refusal to allow any site visit or video audit.
• Pressure to pay fast with large upfront deposits.
• Vague answers about capacity, materials, or lead times.

Financial Red Flags

Payment details deserve special caution.

• Bank account name differs from the registered entity.
• Sudden requests to change payment to a new account.
• Personal accounts used instead of a company account.

VALO Vietnam's view: A mismatched bank account is the single most common fraud signal we see. Always pause and reverify.
