COMPANYPROOF · SUPPLIER DUE DILIGENCE
Supplier due diligence starts with the right legal entity.
A supplier questionnaire is a set of claims. Check the legal identity behind those claims, compare the available company records and keep the evidence your procurement team needs to explain its decision.
A practical supplier due diligence checklist
Ask for the legal name, registration number, country of registration and registered address. Compare these details with the contract and invoice. If the supplier uses a trading name, establish its relationship to the company that will sign the agreement.
Next, check company status and incorporation date. Review directors, shareholders and group relationships where the relevant records are available. For a financial claim, preserve the currency, reporting period and whether the figure covers the individual company or a consolidated group.
- Confirm the legal entity and contracting party.
- Check status, registration details and material company assertions.
- Review ownership and financial source records when available.
- Record unresolved questions and assign a reviewer.
- Complete payment, sanctions and other controls required by your policy.
- Set review dates and monitor eligible company changes.
Turn supplier statements into individual checks
Paste company information from a questionnaire, email or research summary into CompanyProof. Include the company name and jurisdiction. The checker identifies factual assertions and returns the evidence available for each result, asking for clarification when key identity details are missing.
For automated onboarding, use the business verification API and company-profile endpoints. Store the original statement beside the observed value. This makes it possible to explain why a statement was accepted, corrected or referred for review without reconstructing the research later.
Keep missing information separate from supplier risk
An unavailable shareholder record can reflect registry disclosure limits. It is not evidence that a supplier concealed its ownership. Equally, an active registration is not proof that the supplier can deliver a contract or that an invoice contains legitimate payment instructions.
Use CompanyProof for company facts and their evidence. Apply your existing approval policy to financial resilience, sanctions, operational capability and bank details. When an eligible monitored company fact changes, reopen the relevant part of the review rather than repeating every check automatically.
Checks and evidence
| Supplier check | Evidence to retain | Question for procurement |
|---|---|---|
| Legal identity | Registered name, number and jurisdiction | Is this the entity signing our contract? |
| Company status | Observed status and check time | Does it match the supplier statement? |
| Ownership | Returned records and disclosure gaps | What is known and what needs review? |
| Financial statement | Entity, period, currency and source | Are the figures comparable? |
| Payment instructions | Your separate beneficiary checks | Have we verified who receives the money? |

Supplier due diligence: your questions answered
What is supplier due diligence?
It is the review of a supplier before and during a business relationship. Company identity, ownership, financial capacity and operational or risk checks depend on the contract and your policy.
What should a supplier due diligence checklist include?
Include legal identity, registration status, the contracting party, material ownership and financial information, unresolved questions, approval ownership and a recheck schedule.
What is the difference between supplier and vendor due diligence?
Procurement teams often use supplier and vendor interchangeably. Vendor due diligence can also describe a seller-commissioned review in an acquisition, which is a different workflow.
Can CompanyProof check a supplier questionnaire?
You can paste the company information into the text checker. It evaluates factual company assertions using the available evidence and asks for missing identity details.
Can I automate supplier verification?
Use the company search, profile and claim-verification contracts to integrate checks into onboarding. Define your own review and approval rules around the returned evidence.
Is active company status enough to approve a supplier?
No. Active status is one company fact. It does not establish financial resilience, delivery capability or payment safety.
How should missing ownership information be treated?
Record the gap, its source and any disclosure limitation. Follow your review policy; do not treat unavailable information as a verified negative finding.
How do I compare supplier financial figures?
Match the legal entity, reporting period, currency, units and accounting scope. A group revenue figure may not describe the company signing your contract.
How often should supplier checks be repeated?
Use your organisation's risk and contract policy to set review dates. Eligible claim monitoring can flag changes between those scheduled reviews.
Does CompanyProof replace every supplier risk check?
No. It supplies company information and evidence for factual checks. Your procurement process remains responsible for additional controls and the approval decision.
